ELECTRICAL SAFETY
WARNING: To avoid electrical hazards, fire hazards or damage to the
tool, use proper circuit protection.
This tool is wired at the factory for 120 V operation. It must be connected to
a 120 V 15 A time delayed fuse or circuit breaker. To avoid shock or fire,
replace power cord immediately if it is worn, cut or damaged in any way.
ALWAYS WEAR A DUST MASK DESIGNED FOR USE WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
WARNING: Some dust created by power sanding, sawing, grinding,
drilling and other construction activities contains chemicals known to cause
cancer, birth defects or other reproductive harm. 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 level of risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals, work in a
well-ventilated area and work with approved safety equipment such as dust
masks that are specially designed to filter out microscopic particles.
GENERAL SAFETY WARNINGS

5
GENERAL SAFETY RULES
WARNING: Read and understand
all instructions. Failure to follow all
instructions listed below may result in
electric shock, fire and/or serious personal
injury.
WORK AREA
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in potentially
explosive environments, such as in the
presence of flammable liquids, gas or dust.
Power tools create sparks which may
ignite the dust or fumes.
Keep bystanders, children and visitors
away while operating the tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
Double insulated tools are equipped with a
polarized plug (one blade is wider than the
other). This plug will fit in a polarized plug
only one way.
If the plug does not fit fully into the outlet,
reverse the plug. If it still does not fit,
contact a qualified electrician to install a
polarized outlet. Do not alter the plug in
any way. Double insulation eliminates the
need for the three-prong grounded power
cord and grounded power supply system.
Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and
refrigerators. There is increased risk of
electric shock if your body is grounded.
Do not expose power tools to rain or wet
conditions. Water entering the power tool
will increase the risk of electric shock.
Do not abuse the cord. Never use the cord
to carry the tool or pull the plug from an
outlet. Keep cord away from heat, oil,
sharp edges or moving parts. Replace
damaged cords immediately. Damaged
cords increase the risk of electric shock.
When operating a power tool outdoors,
use an outdoor extension cord marked “W-
A” or “W”. These cords are rated for
outdoor use and reduce the risk of electric
shock.
PERSONAL SAFETY
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use the tool while tired
or under the influence of drugs, alcohol or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose clothing
or jewelry.
Contain long hair. Keep your hair, clothing
and gloves away from moving parts. Loose
clothing, jewelry or long hair can be caught
in moving parts.
!
POWER TOOL SAFETY

6
PERSONAL SAFETY – cont’d
Avoid accidental starting. Be sure the
switch is OFF before plugging in. Carrying
tools with your finger on the switch or
plugging in tools that have the switch ON
invites accidents.
Remove adjusting keys or wrenches
before turning the tool ON. A wrench or
key that is left attached to a rotating part of
the tool may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. Proper footing and
balance enables better control of the tool
in unexpected situations.
Use safety equipment. Always wear eye
protection.
Dust mask, non-skid safety shoes, hard
hat or hearing protection must be used for
appropriate conditions.
TOOL USE AND CARE
Use clamps or another practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
Do not force the tool. Use the correct tool
for your application. The correct tool will do
the job better and safer at the rate for
which it was designed.
Do not use the tool if the power switch
does not turn it ON or OFF. Any tool that
cannot be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the power source
before making any adjustments, changing
accessories or storing the tool. Such
preventive safety measures reduce the risk
of starting the tool accidentally.
Store idle tools out of reach of children and
other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained
cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
Check for misalignment or binding of
moving parts, breakage of parts and any
other condition that may affect the tool’s
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools.
Use only accessories that are
recommended by the manufacturer for
your model. Accessories that may be
suitable for one tool may become
hazardous when used on another tool.
SERVICE
Tool service must be performed only by
qualified personnel. Service or
maintenance performed by unqualified
personnel could result in risk of injury.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to
follow Maintenance instructions may
create a risk of electric shock or injury.
POWER TOOL SAFETY

WARNING: For your safety, do not
plug in your reciprocating saw until you
have read and understood this Owner’s
Manual.
Always wear eye protection that conforms
with CSA requirements or ANSI safety
standard Z87.1
Always wear hearing protection and dust
mask. Use only in well ventilated areas.
Use of personal protective equipment and
working in a safe environment will reduce
the risk of injury.
Turn off all electrical power in the vicinity of
work. Contact with ”live” wires could shock
the operator or cause a fire.
Check to make sure the reciprocating saw
power cord and any extension cord are
clear of the area to be cut. Contact with
”live” wires could shock the operator or
cause a fire.
Do not wear gloves, neckties or loose
clothing.
Hold tool by insulated gripping surfaces
when performing an operation where the
saw blade may contact hidden wiring or its
own cord. Contact with a “live” wire will
make exposed metal parts of the tool “live”
and shock the operator.
Always hold the tool with two hands.
Attempting to control the tool with only one
hand is dangerous. It could result in loss of
control and serious injury.
Never hold the workpiece in one hand and
the tool in the other hand when sawing.
Never place the hands near or below the
cutting surface. Clamp the workpiece and
guide the tool with both hands.
Always make sure the work surface is free
from nails and other foreign objects.
Cutting into a nail can cause the blade and
the tool to jump and damage the blade.
Never lay the workpiece on hard surfaces
like concrete, stone, etc. The protruding
blade may cause tool to jump.
DANGER: Always remove the
plug from the power source when
changing blade.
After changing a blade or making
adjustments, make sure the blade clamp
screw is securely tightened. Loose blades
and adjustment devices could be violently
thrown from the tool.
Never use dull or damaged blades. Sharp
blades must be handled with care.
Damaged blades can snap during use.
Dull blades require more force to cut the
workpiece, possibly causing the blade to
break.
Never touch the blade during or
immediately after use. After use the blade
is too hot to be touched
SPECIFIC SAFETY RULES
!

WARNING: Keep the extension
cord clear of the working area. Position
the cord so it will not get caught on the
workpiece, tools or any other obstructions
while you are working with the power tool.
Make sure any extension cord used with
this tool is in good condition. When using
an extension cord, be sure to use one of
heavy enough gauge to carry the current
the tool will draw. An undersized cord will
cause a drop in line voltage resulting in
loss of power and overheating.
The table at right shows the correct size to
use according to cord length and
nameplate ampere rating. If in doubt, use
the next heavier gauge. The smaller the
gauge number the heavier the cord.
Be sure your extension cord is properly
wired and in good condition. Always
replace a damaged extension cord or have
it repaired by a qualified electrician before
using it. Protect your extension cord from
sharp objects, excessive heat and damp or
wet areas.
Use a separate electrical circuit for your
power tools. This circuit must not be less
than 14 gauge wire and should be
protected with either a 15 A time delayed
fuse or circuit breaker. Before connecting
the power tool to the power source, make
sure the switch is in the OFF position and
the power source is the same as indicated
on the nameplate. Running at lower
voltage will damage the motor.

REMOVING BLADE
To remove the blade, simply loosen the
blade clamp set screw and pull the blade
out of the blade clamp.
ADJUSTING PIVOTING SHOE
The pivoting shoe will pivot to follow the
angle of the blade to the workpiece. This
action ensures the flat surface of the shoe
is against the workpiece for better cutting
action and easier control of the saw.
The shoe can be adjusted in or out,
allowing the use of the blade teeth at
different points of the blade. This will
provide longer blade life as one section of
the blade becomes dull.
1. To adjust the pivoting shoe (1), loosen
the two pivoting shoe hex screws (2)
on the lower side of the saw using the
4 mm hex key (3) supplied (see
Fig. 2).
2. Slide the pivoting shoe in or out until it
is in the appropriate position.
3. Lock the pivoting shoe in place by
tightening the pivoting shoe hex
screws.
4. Pull outward on pivoting shoe to
ensure it is firmly locked in place.
