185MM CIRCULAR SAW ENG
OPERATING INSTRUCTIONS
Note: Before using the power tool, read the instruction manual carefully.
1. Intended use
The machine is intended for lengthways and crossways cutting of wood with straight cutting lines as
well as mitre cuts in wood.
2. Before using your power tool
1) Before using your saw, check for foreign objects in wood, such as nails, screws, etc. and remove
them as required
2) Before using your saw, the anti-rust oil on the saw blade must be removed, otherwise the wood will
become soiled.
3. Adjusting the cutting depth
1) Ensure that the saw is facing away from you.
2) Loosen the depth locking lever.
3) Hold the base plate flat against the edge of the workpiece and lift the body of the saw until the blade
is at the right depth (See Fig 1). Use the depth scale to determine the cutting depth.
4) Tighten the depth locking lever.
Note: Always use the correct blade depth setting. The correct blade depth setting for all cuts should not
be more than a full tooth of the blade teeth below the material being cut. Allowing more depth will
increase the chance of kickback and result in a rough cut.
4. Adjusting the cutting angle
The saw can be adjusted to cut at any angle between 0° and 45°. When making 45° bevel cuts, there is
a blade guide notch in the saw base to help you line up the blade with the line of cut. Align your line of
cut with the inner blade guide notch on the base of the saw when making 45° bevel cuts.
1) Loosen the bevel locking knob located at the front of the base plate (See Fig 2).
2) Tilt the body of the saw until the required angle is reached using the bevel scale as a guide.
3) Tighten the bevel locking knob to secure the base plate.
Note:
•Always make a trial cut in a scrap piece of material along a guideline to determine how much you
should offset the blade from the guideline to make an accurate cut.
•For bevel cuts, the cutting depth is smaller than the setting indicated on the cutting-depth scale.
5. Switching On and Off
The machine is equipped with a lock-off button to avoid unintentional starting.
1) To start the machine, first push the lock-off button for the on/off switch and then press the on/off
switch and keep it pressed (See Fig 3)
2) To switch off the machine, release the on/off switch
Note: For safety reasons, the on/off switch cannot be locked, it must remain pressed during the entire
operation.
6. Suing the parallel guide
10

185MM CIRCULAR SAW ENG
The parallel guide allows you to make parallel cuts in a sheet of wood, all at the same width.
1) Loosen the parallel guide locking knob. Slide the parallel guide through the parallel guide slots in the
base plate (See Fig 4).
2) Adjust the parallel guide to the required width and secure it in position with the parallel guide locking
knob.
3) Ensure that the parallel guide rests against the wood along its entire length to give a consistent
parallel cut.
7. Mounting or replacing the saw blade
Warning: Always wear sturdy gloves when handling or changing blades as they can be very
sharp. Only use sharp and undamaged saw blades. Cracked or distorted saw blades must be replaced
immediately.
1) Place the saw on its side on a flat surface. Rotate the saw blade by hand whilst depressing the
spindle lock button until the blade locks. The spindle lock button may be actuated only when the saw
spindle is at a standstill. Otherwise, the power tool can be damaged.
2) Whilst depressing the spindle lock button, unscrew the blade bolt anticlockwise with the hex key
provided (See Fig 5).
3) Remove the outer blade flange and the blade bolt.
4) Raise the lower blade guard using the blade guard lever. Remove the saw blade from the inner
flange and pull it out.
5) Clean the saw blade flanges thoroughly before mounting the new saw blade.
6) Mount the new saw blade onto the spindle and against the inner flange. If bore diameter of saw
blade is Ф16mm, before mount the saw blade, take out the bushing on the spindle (See Fig 6).
7) Replace the outer flange and tighten the blade bolt.
Note:
•The direction in which the blade rotates has to be the same as the direction of the arrow marked on
the upper blade guard. Ensure that the spindle lock button is released. Before using the saw again,
check that the safety devices are in good working order.
•After replacing the saw blade, make sure that the saw blade runs freely by turning the blade by hand.
Plug the machine into a power socket and run the saw under no load to check that it runs smoothly
before using it to cut any material.
•Do not under any circumstances use grinding discs as the cutting tool.
8. Operation
1) Making a cut
a) Mark the line of cut on the workpiece. Adjust the depth of cut and bevel angle as required.
b) When making 90° cross or rip cuts, align your line of cut with the outer blade guide notch on the base
of the saw.
c) When making 45° bevel cuts, align your line of cut with the inner blade guide notch on the base of the
saw.
d) Rest the front edge of the base on the workpiece. Make sure the power cord is out of the way of saw
the blade and not in the line of cut.
e) Start the machine by push the lock-off button and press the on/off switch.
Note: Always let the blade reach full speed before you begin to cut into the workpiece.
11

185MM CIRCULAR SAW ENG
f) Slowly push the saw forward using both hands. Apply downward pressure to keep the saw steady
and only enough forward pressure to keep the blade cutting (See Fig 7).
g) When making a cut always use steady, even pressure. Forcing the saw causes rough cuts and could
shorten the life of the saw or cause kickback. Allow the blade and the saw to do the work.
h) After completing your cut, release the switch and allow the blade to come to a complete stop. Do not
remove the saw from the workpiece while the blade is moving.
Note: Since blade thickness varies, always make a trial cut in scrap material along the guideline to
determine how much, if any, the guideline must be offset to get an accurate cut.
2) Making a plunge cut
a) Adjust the depth of cut as required.
b) Adjust the bevel setting to 0°.
c) Raise the lower blade guard lever to expose the saw blade and firmly rest the front of the base flat
against the workpiece with the main handle raised so the blade does not touch the workpiece.
d) With the blade just clearing the workpiece, start the machine by push the lock-off button and press
the on/off switch.
e) Always let the blade reach full speed before you begin to cut into the workpiece.
f) Slowly lower the saw into the workpiece, using the front of the base resting on the workpiece as a
hinge point.
Note: As soon as the blade starts cutting the material, release the lower blade guard lever.
g) After completing your cut, release the switch and allow the blade to come to a complete stop. Do not
remove the saw from the workpiece while the blade is moving.
h) If the corners of your pocket cut are not completely cut through, use a jigsaw to finish the corners.
Warning:Always cut in a forward direction when making a pocket cut. Cutting in the reverse
direction could cause the saw to climb up on the workpiece and back toward you, possibly causing
serious injury.
Warning:Never tie the lower blade guard in a raised position. Leaving the blade exposed could
lead to serious injury.
WORKING HINTS FOR YOUR POWER TOOL
1.Protect saw blades against impact and shock.
2.Guide the machine evenly and with light feed in the cutting direction. Excessive feed significantly
reduces the service life of the saw blade and can cause damage to the power tool.
3.Sawing performance and cutting quality depend essentially on the condition and the tooth form of the
saw blade. Therefore, use only sharp saw blades that are suited for the material to be worked.
MAINTENANCE
Warning: Remove the plug from the socket before carrying out any adjustment, servicing
or maintenance.
1. Keep the power tool ventilation slots clean and free from obstructions. If available, blow compressed
air into the vents to clear any internal dust (safety goggles must be worn when undertaking this
process).
2. Never use water or chemical cleaners to clean your power tool. Wipe clean with a dry cloth.
12

185MM CIRCULAR SAW ENG
3. The moving guard must always be able to move freely and retract automatically. Therefore, always
keep the area around the moving guard clean. Remove dust and chips by blowing out with compressed
air or with a brush.
4. Resin and glue residue on the saw blade produces poor cuts. Therefore, clean the saw blade
immediately after use.
5. Always store your power tool in a dry place.
6. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
TROUBLESHOOTING
1. If your power tool will not operate, check the power at the mains plug, or check the carbon brushes.
2. If your power tool doesn’t work properly, check that saw blade for sharpness, replace it with a new
one if worn.
3. If a fault can’t be rectified, return the power tool to an authorized dealer for repair.

GENERAL POWER TOOL SAFETY WARNINGS
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.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify 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.
b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, 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.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use
of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common 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 inattention while operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will
reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch isin 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 energising power tools that have the switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of
the power tool in unexpected situations.
5

185MM CIRCULAR SAW ENG
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g) If devices are provided for the connection ofdust extraction and collection facilities, ensure
these are connected and properly used. Use of dust collection can reduce dust-related hazards.
4) Power tool use and care
a) 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.
b) 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.
c) 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.
d) 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 users.
e) 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 operation. If damaged, have the power
tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these instructions,
taking into account the working conditions and the work to be performed. Use of the power tool
for operations different from those intended could result in a hazardous situation.
5) Service
a) 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 maintained.
ADDITIONAL SAFETY INSTRUCTIONS FOR YOUR POWER TOOL
Warning: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary
handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
1) Do not reach underneath the workpiece. The guard cannot protect you from the blade below the
workpiece.
2) Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
3) Never hold piece being cut in your hands or across your leg. Secure the workpiece to a stable
platform. It is important to support the work properly to minimize body exposure, blade binding, or loss
of control.
4) Hold the power tool by insulated gripping surfaces only, when performing an operation where the
cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will also make exposed
metal parts of the power tool “live” and could give the operator an electric shock.
5) When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
6

185MM CIRCULAR SAW ENG
6) Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades that
do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
7) Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and safety of operation.
8) Kickback causes and related warnings
•Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled
saw to lift up and out of the workpiece toward the operator;
•When the blade is pinched or bound tightly by the kerf 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 toward the
operator.
Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
9) Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces.
Position your body to either side of the blade, but not in line with the blade. Kickback could cause the
saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are
taken
10) When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the
saw motionless 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.
Investigate and take corrective actions to eliminate the cause of blade binding.
11) When restarting a saw in the workpiece, centre the saw blade in the kerf and check that saw teeth
are not engaged into the material. If saw blade is binding, it may walk up or kickback from the
workpiece as the saw is restarted.
12) 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 cut and
near the edge of the panel.
13) Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kickback.
14) Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade
adjustment shifts while cutting, it may cause binding and kickback.
15) Use extra caution when sawing into existing walls or other blind areas. The protruding blade may
cut objects that can cause kickback.
16) Check lower guard for proper closing before each use. Do not operate the saw if lower guard does
not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is
accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and
make sure it moves freely and does not touch the blade or any other part, in all angles and depths of
cut.
17) Check the operation of the lower guard spring. If the guard and the spring are not operating
properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
18) Lower guard function be retracted manually only for special cuts such as “plunge cuts and angle
cuts”. Raise the lower guard by retracting the handle and as soon as the blade enters the material,
release the lower guard. For all other sawing operations, the lower guard should operate automatically.
7

185MM CIRCULAR SAW ENG
19) Always observe that the lower guard is covering the blade before placing saw down on 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 switch is released.
20) Do not reach into the chip ejector with your hands. They could be injured by rotating parts.
21) Do not work overhead with the saw. In this manner you do not have sufficient control over the
power tool.
22) Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility
company for assistance. Contact with electric lines can lead to fire and electric shock.
23) Do not operate the power tool stationary. It is not designed for operation with a saw table.
24) Do not use high speed steel (HSS) saw blades. Such saw blades can easily break.
25) When working with the power tool, always hold it firmly with both hands and provide for a secure
stance. The power tool is guided more secure with both hands.
26) Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure
than by hand.
27) Always wait until the machine has come to a complete stop before placing it down. The tool insert
can jam and lead to loss of control over the power tool.
28) Wear ear protectors with power tool. Exposure to noise can cause hearing loss.
29) Wear safety goggles or eye protection when using this power tool. Use a dust mask or respirator
for applications which generate dust.
30) When an extension cord is required you must ensure it has the correct ampere rating for your
power tool and that it is in a safe electrical condition. Fully unwind extension cords to avoid potential
overheating.
DOUBLE INSULATION
The power tool is double insulated. This means that all the external metal parts are electrically insulated
from the main power supply. This is done by placing insulation barriers between the electrical and
mechanical components making it unnecessary for the power tool to be earthed.
IMPORTANT NOTE
Be sure the supply is the same as the voltage given on the rating plate. The power tool is fitted with a
two-core cable and plug.
Remove the main plug from socket before carrying out any adjustment or servicing.
