3. Personal safety
General safety rules
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.
WARNING Read all instructions. Failure to follow all
instructions listed below may result in electric shock, fire and/
or serious injury. The term “power tool” in all of the warnings
listed below refers to your mains operated (corded) power
tool or battery operated (cordless) power tool.
Save these instructions.
1. Work area
b. Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
a. Keep work area clean and well lit. Cluttered and 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. Avoid accidental starting. Ensure the switch is in the
off position before plugging in. Carrying power tools with
your finger on the switch or plugging in power tools that
have the switch on invites accidents.
c. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
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.
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.
e. Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
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.
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.
c. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
g. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of these devices
can reduce dust related hazards.
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.
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.
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.
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 before
making any adjustments, changing accessories, or
storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
d. When battery pack is not in use, keep it away from
other metal objects like paper clips, coins, keys,
nails, screws, or other small metal objects that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause burns
or a fire.
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. Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from the
battery may cause irritation or burns.
e. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power tools
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
6. 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.
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.
Additional safety rules for reciprocating saws
Always remove the plug from the mains socket before
making any adjustments or maintenance, including
changing the blade.
• When operating the saw, use safety equipment including
safety goggles or shield, ear protection, dust mask and
protective clothing including safety gloves.
• Ensure that the lighting is adequate.
• Keep the area free of tripping hazards.
• Do not let anyone under the age of 18 years operate
this saw.
• Always stand to one side when operating the saw.
• Never use a cracked or distorted saw blade. Only use
sharp blades.
• When cutting round wood, use clamps that prevent the
work piece from turning on both sides of the blade.
• Never use your hands to remove sawdust, chips or waste
close by the blade.
g. Use the power tool, accessories and tool bits etc.,
in accordance with these instructions and in the
manner intended for the particular type of power
tool, 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. Battery tool use and care
a. Ensure the switch is in the off position before
inserting battery pack. Inserting the battery pack into
power tools that have the switch on invites accidents.
b. Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used with
another battery pack.
c. Use power tools only with specifically designated

• Avoid cutting nails. Inspect the work piece and remove all
nails and other foreign objects before beginning sawing.
• Support the work properly.
• When an extension cable is required, you must ensure
that it has the right ampere rating for your power tool and
is in safe electrical condition.
• After long working periods external metal parts and
accessories could be hot.
• Do not force the saw; let the tool do the work at a
reasonable speed. Overloading will occur if too much
pressure is applied and the motor slows resulting in
inefficient cutting and possible damage to the motor.
• Always remove the plug from the mains socket before
making any adjustments or maintenance, including
changing the blade.
WARNINGS. Before connecting a tool to a power source
(mains switch power point receptacle, outlet, etc.) be sure
that the voltage supply is the same as that specified on the
nameplate of the tool. A power source with a voltage greater
than that specified for the tool can result in serious injury to
the user, as well as damage to the tool.
• Never reach over the blade to remove waste or off cuts.
• Do not attempt to free a jammed blade before first
switching off the machine.
• Do not slow or stop a blade with a piece of wood. Let the
blade come to rest naturally.
• If you are interrupted when operating the saw, complete
the process and switch off before looking up.
• Periodically check that all nuts, bolts and other fixings are
properly tightened.
• Always hold the saw on parts that are insulated. If you
accidentally cut into hidden wiring or the saw’s own cable,
the metal parts of the saw will become “live”.
• Never saw near combustible liquids or gases.
The tool must be used only for its prescribed purpose.
Any use other than those mentioned in this Manual will
be considered a case of misuse. The user and not the
manufacturer shall be liable for any damage or injury
resulting from such cases of misuse.
If in doubt, do not plug in the tool. Using a power source
with a voltage less than the nameplate rating is harmful to
the motor.
Wear goggles
The manufacturer shall not be liable for any changes made
to the tool nor for any damage resulting from such changes.
Wear earmuffs
Wear a breathing mask
Even when the tool is used as prescribed it is not possible to
eliminate all residual risk factors. The following hazards may
arise in connection with the tool’s construction and design:

Using the pendulum control
Rotating the rear handle
1. With the pendulum control
1. The rear handle (8) can
be rotated, there are eight
set positions of operation,
spaced 45° apart.
(2) set at
the blade
moves backwards and
forwards only and does
not swing up and down as
well. This is called “straight
cutting”. Use straight cutting
when sawing hard materials
such as metal.
2. The rear handle must be
“locked” into one of the eight
preset positions. It must not
be used at any position in
between these eight preset
positions as it might rotate
during use and create a hazard.
Straight Cutting
2. With the pendulum control
(2) set at
the blade
swings up and down as well
as moving backwards and
forwards. This “pendulum
action cutting” is very
efficient when cutting softer
materials. It provides a more
aggressive and faster cut.
3. To rotate the handle press on
the rotating release switch
(9) and move the handle to
one of the present positions.
General cutting
1. Hold the saw firmly in front
and clearly away from you.
Pendulum Cutting
NOTE. Pendulum action cutting can leave a rough finish.
2. Make sure that the blade is
clear of any obstruction and
that the power cord or any
extension cord is out of the
path of the blade.
Use a file or rasp to clean up the cut edge if necessary.
WARNING. Use the straight cutting mode when you wish
to make curved or clean cuts, even when working with
soft materials.
3. Ensure that the material to
be cut is held firmly. Small
work pieces should be held
in a vice or clamped to the workbench.
4. Mark out the cutting line.
5. Press the lock-off button and squeeze the trigger.
6. Wait until the saw has reached maximum speed.
7. Place the shoe on the work piece and begin sawing.
NOTE. Use only enough pressure to keep the saw cutting.
Do not force the cutting; allow the blade and the saw to do
the work.
WARNING. Use of excessive pressure that causes bending
or twisting of the blade may cause the blade to break.

Plunge cutting
1. Mark the line of the cut.
Cleaning
1. Keep the tool’s air vents unclogged and clean at all
times.
2. Choose a point inside the
area to be cut out and place
the tip of the blade over that
point.
2. Remove dust and dirt regularly. Cleaning is best done
with a rag.
3. Re-lubricate all moving parts at regular intervals.
4. Never use caustic agents to clean plastic parts.
3. Rest the front edge of the
shoe on the work piece
and hold the saw firmly in
position.
CAUTION. Do not use cleaning agents to clean the plastic
parts of the saw. A mild detergent on a damp cloth is
recommended. Water must never come into contact with
the saw.
4. Press the lock-off button and squeeze the trigger to start
the cutting action.
General inspection
Regularly check that all the fixing screws are tight.
They may vibrate loose over time.
WARNING. Make sure that the blade does not touch the
work piece until the blade has reached maximum speed
since this could cause loss of control and serious injury.
Metal cutting
Repairs
Metals such as sheet steel,
pipe, steel rods, aluminium,
brass and copper can be cut
with your saw. Be careful not to
bend or twist the blade and do
not force the cutting action.
Only an authorised service centre should replace the
cordset or carry out other repairs. If the cordset is damaged
or worn, have it repaired or replaced by an authorised
service centre.
We recommend that you use
cutting oil to lubricate the cut
when sawing soft metals and
steel. It keeps the blade cooler
and prolongs blade life.
CAUTION. Clamp the work firmly and cut close to the
clamping point to minimise vibration. When cutting conduit
pipe or angle iron, clamp the work in a vice if possible and
cut close to the vice. To cut thin sheet metal, sandwich
the sheet between hardboard or plywood and clamp the
layers to prevent vibration and the tearing of the metal.
