GENERAL SAFETY RULES
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable liquids,
gases or dust. Power tools create sparks which may ig-
nite the dust or fumes.
3. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never mod-
ify the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfac-
es such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
4. Do not abuse the cord. Never use the cord for car-
rying, pulling or unplugging the power tool. Keep cord
away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric
shock.
5. When operating a power tool outdoors, use an ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.
6. If operating a power tool in a damp location is un-
avoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI reduces the risk of elec-
tric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inatten-
tion while operating power tools may result in serious
personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a respira-
tory mask, non-skid safety shoes and hearing protection
used for appropriate conditions will reduce the risk of
personal injury.
3. Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites
accidents.
4. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal
injury.
5. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jew-
elry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

GENERAL SAFETY RULES
7. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
2. Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained us-
ers.
5. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s opera-
tion. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
power tools.
6. Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situa-
tion.
8. Use clamps to secure your workpiece to a stable
surface. Holding a workpiece by hand or using your
body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.
SERVICE
1. Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is main-
tained.
CALIFORNIA PROPOSITION 65 WARNING
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities may contain
chemicals, including lead, known to the State of Califor-
nia to cause cancer, birth defects, or other reproductive
harm. Wash hands after handling. Some examples of
these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other
masonry products.
• Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies depending on
how often you do this type of work. To reduce your ex-
posure to these chemicals, work in a well-ventilated area
with approved safety equipment such as dust masks
specially designed to filter out microscopic particles.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

CIRCULAR SAW SAFETY WARNINGS
WARNING! Do not operate the power tool until you have read and understood the following instructions and
the warning labels.
CIRCULAR SAW SAFETY
1. Work environment. Do not operate the tool in wet
or damp conditions; doing so significantly increases the
risk of electrical shock. Do not operate the tool in the
presence of flammable liquids or gases. When operating
the tool from an elevated position, be aware of people or
things beneath you.
2. Personal Safety. Always wear ANSI Z87.1-approved
glasses, a dust mask and hearing protection when using
the saw. Do not wear loose clothing or jewelry as they
might get drawn in by the tool.
3. Preventing electric shock. When working with the
tool, make sure to keep the blade away from any power
cables, extension cords or wiring. Only hold the tool by
insulated gripping surfaces when performing an opera-
tion in case the cutter contacts its own cord. Cutting a
“live” wire may make exposed metal parts of the tool
“live” and could give the operator an electric shock.
4. Inspect your tool before operation. Before operation,
check the tool for any damage or missing parts. Do not
use the tool if any part is missing or damaged. Do not
use the tool if the power switch is faulty, the plug or
cable is damaged, or the tool produces sparks, smoke,
or unpleasant odors (you may smell brushes wearing
down for a few minutes as the tool breaks in during the
first use, that is normal). Make sure all adjustments are
correct and all connections are tight.
5. Lower blade guard safety. Check lower blade guard
for functionality before each use. To check the lower
guard, unplug the tool and open the lower guard by lifting
the blade guard lever, then release and watch the guard
close. Do not operate saw if lower guard does not move
freely or close immediately. Leaving a blade exposed is
very dangerous and can lead to serious personal injury.
• Never clamp, tie, or otherwise fix the lower guard into
the open position.
• If the saw is accidentally dropped, the lower guard may
bend. Raise the lower guard with the blade guard lever
to make sure it moves freely without touching the blade
or any other saw part for all angles and depths of pos-
sible cuts.
• Always ensure that the lower guard is covering the
blade before placing the saw down on a bench or floor.
An unprotected, coasting blade will cause the saw to
walk backwards, cutting whatever is in its path. Be aware
of the time it takes for the blade to stop after the switch
is released.
• The lower guard should be retracted manually only for
special cuts such as plunge cuts/pocket cuts. Raise the
lower guard by retracting the lever. As soon as the blade
enters the material, the lower guard must be released.
For all other sawing, the lower guard should operate au-
tomatically.
6. Supporting the workpiece. Never hold a piece being
cut in your hands or across your legs. It is important to
support the work properly to minimize body exposure,
blade binding, or loss of control.
7. Starting the tool. Always start the saw before the
blade comes into contact with the workpiece. Let the
blade reach full speed before using the tool. The reaction
to the torque as the motor accelerates to full speed may
cause the tool to kick back.
8. Standing position. Keep your body positioned to ei-
ther side of the saw blade, but not in line with the saw
blade. Kickback could cause the saw to jump backwards.

CIRCULAR SAW SAFETY WARNINGS
WARNING! Do not operate the power tool until you have read and understood the following instructions and
the warning labels.
CIRCULAR SAW SAFETY
9. During the cut. Keep hands away from the cutting
area and the blade. Do not reach underneath the work-
piece. The blade guard cannot protect you from the
blade protruding from the underside of the workpiece.
Do not attempt to remove cut material when the blade
is moving.
10. Reducing kickback. Kickback is a sudden reaction
to a pinched, bound or misaligned saw blade, causing
an uncontrolled saw to lift up and out of the work piece
toward the operator. When the blade is pinched or bound
tightly by the kerf (width of cut) closing down, the blade
stalls and the motor reaction drives the unit rapidly back
toward the operator. If the blade becomes twisted or
misaligned in the cut, the teeth at the back edge of the
blade can dig into the top surface of the wood causing
the blade to climb out of the kerf and jump back towards
the operator. Take the proper precautions below to re-
duce the risk of kickback.
• Maintain a firm grip on the saw and position your body
and arm in a way that allows you to resist kickback forc-
es. Kickback forces can be controlled by the operator, if
proper precautions are taken.
• When a blade is binding (or when interrupting a cut for
any reason), release the trigger and hold the saw motion-
less in the material until the blade comes to a complete
stop. Never attempt to remove the saw from the work
or pull the saw backward while the blade is in motion or
kickback may occur.
• When restarting a saw in the workpiece, center the
blade in the kerf and check that the teeth are not en-
gaged into the material. If the saw blade is binding, it
may walk up or kickback from the work piece as the saw
is restarted. Investigate and take corrective actions to
eliminate the causes of blade binding.
• Support large panels to minimize the risk of blade
pinching and kickback. Large panels tend to sag under
their own weight. Supports must be placed under the
panel on both sides, near the line of the cut and near the
edge of the panel.
• Do not use dull or damaged blades. Unsharpened or
improperly set blades produce narrow kerf, causing ex-
cessive friction, blade binding, and kickback.
• The blade depth locking knob and bevel adjustment
locking knob must be tight and secure before making
a cut. If the blade adjustment shifts while cutting, it will
cause binding and kickback.
• Use extra caution when making a plunge cut/pocket cut
into existing walls or other blind areas. The protruding
blade may contact objects that could cause kickback.
11. Turning off the tool. Blades coast after turning the
saw off. Wait until the blade stops before reaching for
loose material or setting the tool down.
12. Replacing saw blade. Check the blade for chipped
or broken teeth. Do not use dull or damaged blades.
Unsharpened or improperly set blades produce narrow
kerf, causing excessive friction, blade binding, and kick-
back. Always use blades with correct size arbor holes.
Blades that do not match the mounting hardware of the
saw will run eccentrically, causing a loss of control. See
“Replacing the Blade.”
13. Making adjustments. Always turn off and unplug
the saw before making adjustments or changing at-
tachments. Accidental start-ups may occur if the saw is
plugged in during an accessory change or adjustment.

2A 18 gauge 16 gauge 16 gauge 14 gauge
IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and
should be done only by qualified service personnel using identical replacement parts. Always use original factory
replacement parts when servicing.
1. Polarized Plugs. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than
the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the
plug. If it still does not fit, contact a qualified electrician to install a proper outlet. Do not modify the machine plug
or the extension cord in any way.
2. Ground fault circuit interrupter protection (GFCI) should be provided on the circuit or outlet used for this power
tool to reduce the risk of electric shock.
3. Service and repair. To avoid danger, electrical appliances must only be repaired by a qualified service technician
using original replacement parts.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The table below shows
the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The
smaller the gauge number, the heavier the cord.
DOUBLE-INSULATED CHARGER
The charger’s electrical system is double-insulated where two systems of insulation are provided. This
eliminates the need for the usual three-wire grounded power cord. Double-insulated tools do not need
to be grounded, nor should a means for grounding be added to the product. All exposed metal parts are
isolated from the internal metal components with protecting insulation.
1. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition.
Always replace a damaged extension cord or have it repaired by a qualified person before using it.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on
plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be
protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in
the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running
at a lower voltage will damage the motor.

• Avoid dangerous environments – Do not charge the
battery pack in rain, snow or in damp or wet locations.
Do not use the battery pack or charger in the presence
of explosive atmospheres (gaseous fumes, dust or flam-
mable materials) because sparks may be generated when
inserting or removing the battery pack, which could lead
to a fire.
• Charge in a well-ventilated area – Do not block the
charger vents. Keep them clear to allow for proper ven-
tilation. Do not allow smoking or open flames near a
charging battery pack. Vented gases may explode.
NOTE: The safe temperature range for the battery charg-
ing is 41°F to 104°F. Do not charge the battery outside
in freezing weather; charge it at room temperature.
• Maintain charger cord – When unplugging the char-
ger, pull the plug, not the cord, from the receptacle to
reduce the risk of damage to the electrical plug and cord.
Never carry the charger by its cord or yank it by the cord
to disconnect it from the receptacle. Keep the cord away
from heat, oil and sharp edges. Make sure the cord will
not be stepped on, tripped over or subjected to dam-
age or stress when the charger is in use. Do not use the
charger with a damaged cord or plug. Replace a dam-
aged charger immediately.
• Do not use an extension cord unless it is absolutely
necessary – Using the wrong, damaged or improperly
wired extension cord poses a risk of fire and electric
shock. If an extension cord must be used, plug the char-
ger into a properly wired 16 gauge or larger extension
cord with the female plug matching the male plug on the
charger. Make sure that the extension cord is in good
electrical condition.
• Charger is rated for 120 volt AC only – The charger
must be plugged into an appropriate receptacle.
• Use only recommended attachments – Use of an at-
tachment not recommended or sold by WEN Products
may result in risk of fire, electric shock or personal in-
jury.
• Unplug charger when not in use – Make sure to re-
move battery packs from unplugged chargers.
• Do not burn or incinerate battery packs – Battery
packs may explode, causing personal injury or dam-
age. Toxic fumes and materials are created when battery
packs are burned.
• Do not crush, drop or damage battery packs – Do not
use the battery pack or charger if they have sustained a
sharp blow, been dropped, run over or have been dam-
aged in any way (i.e. pierced with a nail, hit with a ham-
mer, stepped on, etc.).
• Do not disassemble – Incorrect reassembly may pose
a serious risk of electric shock, fire or exposure to toxic
battery chemicals. If the battery or charger are damaged,
call WEN customer service at 1-800-232-1195 for as-
sistance.
• Battery chemicals cause serious burns – Never let a
damaged battery pack contact the skin, eyes or mouth.
If a damaged battery pack leaks battery chemicals, use
rubber or neoprene gloves to safely dispose of it. If skin
is exposed to battery fluids, wash the affected area with
soap and water and rinse with vinegar. If eyes are ex-
posed to battery chemicals, immediately flush with wa-
ter for 20 minutes and seek medical attention. Remove
and dispose of contaminated clothing.
• Store your battery pack and charger in a cool, dry
place – Do not store the battery pack or charger where
temperatures may exceed 104 °F, such as in direct sun-
light or inside a vehicle or metal building during the
summer.
• Do not short circuit – A battery pack will short circuit if
a metal object makes a connection between the positive
and negative contacts on the battery pack. Do not place
a battery pack near anything that may cause a short cir-
cuit, such as paper clips, coins, keys, screws, nails and
other metallic objects. A short-circuited battery pack
poses a risk of fire and severe personal injury.
BATTERY & CHARGER SAFETY WARNINGS
Despite all of the safety precautions, caution must always be taken when handling batteries. The following
points must be obeyed at all times to ensure safe use. Safe use can only be guaranteed if undamaged cells are
used. Incorrect handling of the battery pack can cause cell damage.
WARNING! To reduce the risk of electric shock,
always unplug the charger before performing any
cleaning or maintenance. Do not allow water to
flow into the charger. Use a Ground Fault Circuit
Interrupter (GFCI) to reduce shock hazards.

BATTERY & CHARGER SAFETY WARNINGS
ABOUT THE BATTERY
1. The battery pack has to be charged completely before you use the tool for the first time.
2. For optimum battery performance, avoid low discharge cycles by charging the battery pack frequently.
3. Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the latest when
its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery pack are no longer capable
of meeting the high power requirements needed for the proper operation of your tool, and therefore pose a safety
risk.
4. Do not throw battery packs into an open fire as this poses a risk of explosion. Do not ignite the battery pack or
expose it to fire.
5. Do not exhaustively discharge batteries. Exhaustive discharge will damage the battery cells. The most common
cause of exhaustive discharge is lengthy storage or non-use of partially discharged batteries. Stop working as soon
as the performance of the battery falls noticeably or the electronic protection system triggers. Place the battery pack
in storage only after it has been fully charged.
6. Protect batteries and the tool from overloads. Overloads will quickly result in overheating and cell damage inside
the battery housing even if this overheating is not apparent externally.
7. Avoid damage and shocks. Immediately replace batteries that have been dropped from a height of more than
one meter or those that have been exposed to violent shocks, even if the housing of the battery pack appears to be
undamaged. The battery cells inside the battery may have suffered serious damage. In such instances, please read
the waste disposal information for proper battery disposal.
8. If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch off the equip-
ment for safety reasons.
9. Use only original battery packs. The use of other batteries poses a fire risk and may result in injuries or an explo-
sion.
ABOUT THE CHARGER
Protect battery charger and cord from damage. Keep the charger and its cord away from heat, oil and sharp edges.
Electrical plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with ground-
ed appliances. Unmodified plugs and matching outlets will reduce the risk of electric shock.
Keep the battery charger, battery pack(s), and the cordless tool out of the reach of children.
Do not use the supplied battery charger to charge other cordless tools.
During periods of heavy use, the battery pack will become warm. Allow the battery pack to cool to room temperature
before inserting it into the charger to recharge.
Do not overcharge batteries. Do not exceed the maximum charging times. These charging times only apply to dis-
charged batteries. Frequent insertion of a charged or partially charged battery pack will result in overcharging and
cell damage. Do not leave battery in the charger for days on end.
Never use or charge a battery if you suspect that it has been more than 12 months since last time they were charged.
There is a high probability that battery pack has already suffered dangerous damage (exhaustive discharge).
Do not use battery that have been exposed to heat during the charging process, as the battery cells may have suf-
fered dangerous damage.
Do not use battery that have suffered curvature or deformation during the charging process or those that exhibit
other atypical symptoms (gassing, hissing, cracking, etc.)

ASSEMBLY & ADJUSTMENTS
SETTING THE DEPTH OF CUT
Before making a cut, it is important to set the correct blade depth. The saw’s maximum cutting depth at the 90° set-
ting is 2-1/6 inches (55mm) and 1-3/5 inches (40mm) at the 45° setting. Adjust the depth of cut to accommodate
the depth of the material being cut, but do not allow the saw to cut more than 1/4 inch below the bottom surface of
the material. Excessive blade depth increases the chance of saw kickback. For example, if your workpiece is 2 inches
deep, set the cutting depth around 2-1/8 inches, but no deeper than 2-1/4 inches. To adjust the cutting depth, you
can either reference the depth guide bracket, or the edge of the workpiece as described in the steps below.
WARNING! To avoid injury from accidental startups, be sure that the tool is switched off and disconnected
from the power supply before inspecting the unit, making adjustments, or changing accessories.

Using the depth guide bracket:
1. Make sure that your tool is powered OFF and disconnected from the
power source.
2. Loosen the depth locking knob (Fig. 1 - 1) on the depth guide bracket at
the back of saw.
3. Move the base plate up or down to the desired depth, indicated on the
depth guide bracket.
4. Tighten the depth locking knob to secure the depth setting.
Using the edge of the workpiece:
1. Make sure that your tool is powered OFF and disconnected from the
power source.
2. Raise the lower blade guard (Fig. 2 - 1) by lifting the blade guard lever
(Fig. 2 - 2) to expose the blade. Place the saw base onto the workpiece sur-
face with the saw blade positioned against the side edge of the workpiece.
3. Loosen the depth locking knob (Fig. 1 - 1). Raise or lower the saw body
to obtain the desired depth of cut by observing how deep the blade will cut
relative to the top face of the workpiece.
4. Tighten the depth locking knob to secure the depth setting.
ADJUSTING THE BEVEL ANGLE
The saw can be tilted 50 degrees to the right for creating bevel cuts.
To adjust the bevel angle of the blade:
1. Loosen the bevel adjustment knob (Fig. 3 - 1) on the bevel adjustment
scale (Fig. 3 - 2) at the front of the saw.
2. Tilt the saw to the desired angle. The top edge of the indicator bar will
indicate the angle setting on the bevel angle bracket.
3. Tighten the bevel adjustment knob securely.
4. Make a test cut in scrap lumber and measure the angle of the cut to con-
firm that the bevel angle is properly set. If necessary, adjust the bevel angle
appropriately before cutting the actual work piece.

A line-of-cut indicator notch (Fig. 4 - 1) can be found at the front of the saw
base. This notch helps provide indication of where the cut will be occurring.
NOTE: Since blade thicknesses vary, it is necessary to make test cuts along
a guideline in scrap material to determine the proper alignment of the guide-
line within the notch. This will help to obtain an accurate cut with blades of
various thicknesses.
INSTALLING THE RIP GUIDE
When cutting lumber lengthwise you are usually cutting along the wood’s
grain rather then across the grain. Cutting with the grain of wood is called
“ripping,” also known as a rip cut. Since rip cuts tend to be lengthy, it can
be difficult to accurately follow the guideline the entire distance of the cut.
To assist you in obtaining a straight rip cut, it is recommended to use the
included rip guide (Fig. 5 - 1).
To install the rip guide on your saw, perform the following steps:
1. Make sure that your tool is powered OFF and disconnected from the
power source.
2. The rip guide should be attached from the left side of the saw. Insert the
rip guide (Fig. 5 - 1) through all the slots on the saw base until it extends
out of the base.
3. Adjust the position of the rip guide for the desired width of cut.
4. Securely tighten the rip guide locking knob (Fig. 5 - 2) to hold the rip
guide in position.
CONNECTING DUST COLLECTION
Saw dust generated during cutting operations can be hazardous to your
health. Use a dust extraction system to collect the dust and chips.
1. Attach a dust bag or other dust extraction system (not included) onto the
dust port (Fig. 6 - 1). The dust port’s outer diameter is 1-1/2” (39.1mm);
the inner diameter is 1-3/8” (34.8mm).

OPERATION
TYPES OF CUTS
• Cross-Cutting And Rip Cutting
Cutting directly across the grain of a piece of wood is called “cross-cutting” and is likely the most common type of
cut done with a circular saw. Cutting wood lengthwise, or with the grain, is referred to as “rip cutting.” Attach the
rip guide to your saw to help create straight cuts along the side of your workpiece.
• Bevel Cutting
Cutting the workpiece at a bevel angle between 0° and 50° is called “bevel cutting.” Set the bevel angle prior to
performing your cut.
• Plunge Cutting
A plunge cut is a cut that must be made inside the area of the workpiece rather than starting from an outside edge
and working inward.
NOTE: Plunge cuts can be very dangerous for the novice to attempt.
PREPARING FOR OPERATION
Correct preparation of the workpiece and work area prior to cutting is very important for safe operation.
1. Set the correct depth of cut for your workpiece. Set the bevel angle for bevel cutting and attach the rip guide as
necessary for cross-cutting or rip cutting.
2. Place the workpiece with the “good” side down (the saw blade cuts upward through the material, and may “blow
out” the top side). Set-up and support the workpiece so the cut is always on your right. Securely clamp down the
workpiece so it will not move during the cut.
4. Draw a guideline along the desired path of the cut before starting your saw or the cut.
5. Wear safety goggles, a dust mask, and hearing protection.
WARNING! To prevent serious injury, make sure all the instructions have been read and understood before
operating this tool. Before connecting the tool to its power source, always check to see that the tool is turned
OFF. Accidently starting the saw could result in injury.
STARTING AND STOPPING THE SAW
To start the saw:
1. Press and hold the trigger safety lock (Fig. 7 - 1), and then pull the power
trigger (Fig. 7 - 2) to start the saw.
NOTE: Always let the blade reach full speed before guiding the saw into the
work piece. The blade coming into contact with the workpiece before reach-
ing full speed could cause your saw to kick back towards you.
To stop the saw:
Release the power trigger to stop the saw.
NOTE: Do not remove your saw from the work piece while the blade is still
moving. Allow the blade to come to a complete stop before setting down
the tool.

OPERATION
OPERATING THE SAW
1. Hold the tool firmly with both hands, using both the front handle and rear handle. Avoid placing your hand on the
workpiece while making a cut. If both hands are holding the saw, they cannot be cut by the blade.
2. Make sure that you are not in the path of chips and wood dust being ejected from the saw.
3. Set the front portion of the saw’s base on the workpiece to be cut without letting the blade contact the workpiece.
Position the saw with its motor facing toward the larger section of board that isn’t falling away when cut. Align the
line-of-cut indicator notch (Fig. 4) on the base with your guideline.
4. Turn on the saw and let the blade reach full speed before guiding the saw into the work piece.
5. Ease the tool forward over the workpiece surface, keeping it flat and advancing smoothly while following your
guideline until sawing is completed.
• Do not force the saw forward too quickly in order to try and hurry up the process. Let the tool work at its own pace.
• To make sawing easier and safer, be sure to move the tool forward gently in a straight line. Never force or twist the
saw during operation. Forcing or twisting the tool will result in overheating the motor and will increase the chances
of dangerous kickback, possibly causing severe personal injury.
• If the cut fails to properly follow your intended cut line, release the switch trigger, wait for the blade to stop, and
then remove the tool. Realign saw on a new cut guideline and start the cut again. Do not attempt to turn or force the
tool back to the cut line. Doing so may bind the blade and lead to dangerous kickback and possible serious injury.
6. Once the cut is complete, release the switch trigger. Wait for the blade to completely stop. Check that the lower
blade guard has returned to position surrounding the blade. Now you can safely set the saw down out of the way.
Disconnect the saw from the power source.
CROSS-CUTTING AND RIP CUTTING
Cross-cutting means cutting directly across the grain of a piece of wood and it is likely the most common type of
cut done with a circular saw. As mentioned in “Installing the Rip Guide,” cutting wood lengthwise, or with the grain,
is referred to as rip cutting (or simply “ripping”). Both types of cuts are performed in the same manner with the
exception of the methods used to support and secure the work piece for cutting.
BEVEL CUTTING
Bevel cuts are made using the same technique as crosscuts and ripping described in the previous section. The dif-
ference is that the blade is set at a tilted angle between 0° and 50°. A bevel cut made at an angle to the edge of a
board is called a compound miter. Some compound cuts may require you to manually retract the lower guard to
allow the blade to enter into and/or through the cut.
There are tools better suited for bevel and compound cuts than the hand-held circular saw. Although the inner
line-of-cut indicator notch aids the operator in following the cut’s guideline, the tilted motor housing sometimes
obstructs the operator’s ability to see the blade, making accurate cuts difficult. Before taking on a project with nu-
merous compound or bevel cuts it’s suggested that the inexperienced saw user spends time making practice cuts in
scrap lumber to become familiar with and overcome difficulties associated with compound/bevel cutting.

OPERATION
MAKING PLUNGE CUTS/POCKET CUTS
A plunge cut is a cut that must be made inside the area of the workpiece rather than starting from an outside edge
and working inward. Plunge cuts can be very dangerous for the novice to attempt because of the need to manually
retract the lower guard and perform a plunge cut which is potentially hazardous.
Before performing plunge cuts, it’s recommended that the inexperienced saw user spends time making practice cuts
in scrap lumber to become familiar with and overcome difficulties associated with plunge cuts.
1. Disconnect the saw from the power supply.
2. Set the blade to the correct depth of cut, see “SETTING THE DEPTH OF CUT”.
3. Swing the lower blade guard (Fig. 2 - 1) up using the lower blade guard lever (Fig. 2 - 2).
NOTE: Always raise the lower blade guard with the blade guard lever, not the side of the blade guard to avoid seri-
ous injury.
4. While holding the lower blade guard by the lever, rest the front of the base flat against the workpiece with the rear
handle elevated so the blade does not touch the work piece.
5. Start the saw and let the blade reach full speed.
6. Guide the saw down into the workpiece and make the plunge cut.
WARNING! Always cut in a forward direction when plunge cutting. Cutting in the reverse direction could
cause the saw to climb up on the work piece and back toward you.
7. Release the power trigger (Fig. 7 - 1) and allow the blade to come to a complete stop.
8. Lift the saw from the workpiece.
9. Repeat this procedure for the remaining sides, and then clear the corners out with a hand saw or jig saw.
WARNING! Never clamp, tie, or otherwise fix the lower blade guard in a raised position. Leaving the blade
exposed could lead to serious injury.

MAINTENANCE
REPLACING THE SAW BLADE
The quality of the cut depends on the condition of the saw blade. Never use a dull, rusty, or damaged blade. Before
operation, check the blade and replace if the blade is worn-out or damaged.
Use circular saw blades with 6-1/2-inch diameter and 20mm arbor size. Do not use a blade that does not match the
diameter or arbor of the saw. Do not use a blade that is too thick; this will prevent the arbor bolt from securing the
blade on the arbor. Do not use a blade thicker than 1.2mm (0.045 inch). Replacement saw blades (Model 20625B)
can be ordered from wenproducts.com. Note that parts that wear down over the course of normal use (like saw
blades, carbon brushes, etc.) are not covered by the two-year warranty.
WARNING! To avoid injury from accidental startups, be sure that the tool is switched off and disconnected
from the power supply before inspecting the unit, making adjustments or changing accessories.
WARNING! Wear safety gloves when handling saw blades to prevent injuries from accidentally contacting
the sharp blade tip.
1. Unplug your circular saw from the power source.
2. Press down the spindle lock to prevent the blade from spinning.
3. Using the included 5mm hex wrench, remove the arbor bolt by turning it clockwise (the bolt is left-hand threaded).
4. Remove the washer and outer flange washer.
5. Lift the lower guard and remove the existing blade.
6. Lift the lower guard and slide the new saw blade onto the spindle. Make sure the arrows printed on the blade
match the direction of the arrows shown on the upper blade guard, and the blade teeth are pointing up.
7. Replace the outer flange washer.
8. Press the spindle lock and replace the arbor bolt and washer. Tighten the arbor bolt securely by turning it coun-
terclockwise with the wrench while holding the spindle lock.
9. Check to make sure the blade is properly installed and spins freely inside the housing. Check that the arbor screw
is tightened and the blade does not wobble while spinning.
