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
ammable 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. Unmodied 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 inuence 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 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
nger 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.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair
can be caught in moving parts.
g) 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.
h) Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
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 remove the battery pack, if detachable, 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 and accessories. 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,

7
RECIPROCATING SAW EN
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.
h) Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling
and control of the tool in unexpected situations.
5) Service
a) Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
SAFETY INSTRUCTIONS FOR ALL
SAWS
a) DANGER: 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.
b) Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
c) 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.
d) Never hold workpiece in your hands or across
your leg while cutting. Secure the workpiece to a
stable platform. It is important to support the work
properly to minimise body exposure, blade binding,
or loss of control.
e) 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.
f) When ripping always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the
saw will run off-centre, causing loss of control.
h) 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.
e) Recommendation that the tool always be
supplied via a residual current device with a
rated residual current of 30 mA or less.
FURTHER SAFETY INSTRUCTIONS
FOR ALL SAWS
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.
a) Maintain a rm 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.
b) 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

8
RECIPROCATING SAW EN
saw backward while the blade is in motion
or kickback may occur. Investigate and take
corrective actions to eliminate the cause of blade
binding.
c) 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.
d) Support large panels to minimise 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.
e) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf
causing excessive friction, blade binding and
kickback.
f) 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.
g) Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
SAFETY INSTRUCTIONS FOR SAWS
WITH INNER PENDULUM GUARD
Lower guard function
a) 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.
b) 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.
c) Lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts.” Raise lower guard by
retracting handle and as soon as blade enters the
material, the lower guard must be released. For
all other sawing, the lower guard should operate
automatically.
d) Always observe that the lower guard is covering
the blade before placing saw down on bench or
oor. 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.
ADDITIONAL SAFETY RULES FOR
YOUR CIRCULAR SAW
1. Only use saw blades recommended in the
specication.
2. Do not use any abrasive wheels.
3. Use only blade diameter(s) in accordance with the
markings.
4. Identify the correct saw blade to be used for the
material to be cut.
5. Use only saw blades that are marked with a speed
equal or higher than the speed marked on the tool.

Intended Use
The machine is intended for lengthways and crossways
cutting of wood with straight cutting lines as well as
bevel angles to 45° while resting rmly on the work piece.
1. FITTING/REPLACING A SAW BLADE (SEE FIG. A1, A2, A3)
Press the spindle lock button and rotate the blade bolt (a)
in anti-clockwise direction with the hex key. Remove the
blade bolt (a) and the outer ange (b). Rotate the lower
blade guard clockwise by pushing the guard lever to take
out the old blade (15). Fit a replaced blade. Ensure that
the blade bore is located on the inner ange (c) and the
blade direction arrow points in the same direction as the
lower blade guard arrow. Place the outer ange (b) and
the blade bolt (a) onto the blade bore. Press the spindle
lock button again and use the hex key to tighten the bolt
with 1/4 turn more than nger tight in clockwise direction.
Check if the blade is securely clamped
WARNING: Blade teeth are very sharp. For best
cutting results ensure you use a saw blade suited to the
material and cut quality you need.
2. DEPTH OF CUT ADJUSTMENT (SEE FIG. B)
Lift the depth of cut lock lever and raise the saw body
away from the base plate. Set the depth of cut with the
scale and push the lever down to lock. Always add 3mm
to your depth of cut so that the blade can cut through
the material.
3. BASE PLATE ANGLE ADJUSTMENT (SEE FIG. C1, C2)
Turn the base plate bevel lock in anti-clockwise
direction to loosen the angle scale. Tilt the base plate
away from the machine until the required cutting angle
is adjusted on the angle scale. Tighten the bevel lock by
turning it in clockwise direction. Do not use the depth
of cut scale when making bevel cuts due to possible
inaccuracy.
4. DUST EXTRACTION OUTLET (SEE FIG. D)
Fasten the vacuum adapter (18) onto the dust extraction
outlet until it latches. Additionally fasten the vacuum
adapter (18) to the xed guard with the two screws.
Directly connect a suitable vacuum hose to the adapter.
The vacuum adapter must not be mounted when no
external dust extraction is connected. Otherwise
there is danger of the extraction system becoming
clogged.
Clean the vacuum adapter regularly to ensure
optimum dust extraction. The vacuum cleaner must
be suitable for the material to be worked.
5. HAND GRIP POSITION (SEE FIG. E)
Always hold your saw rmly with both hands when
operating.
6. SAFETY ON/OFF SWITCH (SEE FIG. F)
Your switch is locked off to prevent accidental starting.
Depress the lock off button then the on/off switch and
release the lock off button. Your switch is now on. To
switch off, just release the on/off switch.
The blade may continue to rotate after switching off.
Wait until the machine comes to a complete stop before
setting down.
7. CUTTING GUIDE (SEE FIG. G1 & G2)
There is a cutting guide notch on the front of the base
plate for use with a parallel guide. For straight cuts, use
the 0º guide mark to align with your parallel guide scale.
For a 45º bevel cut, use the 45º guide mark to align with
your parallel guide scale. Securely clamp the parallel
guide. Always make a trial cut to check the setting.

10
RECIPROCATING SAW EN
8. PARALLEL GUIDE ADJUSTMENT (SEE FIG. H)
It is used for making cuts parallel to a workpiece edge
at a chosen distance. Slide the parallel guide arm
through the xture to achieve the required cutting
distance then tighten the lock knob to clamp. It can be
used from both sides of the base plate. For straight
cuts, use the 0° guide mark to align with your parallel
guide scale. For a 45° bevel cut, use the 45° guide mark
to align with your parallel guide scale. Securely clamp
the parallel guide.
Note: It is best to carry out a trial cut.
9. CUTTING OPERATION
Set the required base plate angle and cutting depth.
Place front of the base plate on the workpiece (do not
allow the blade to touch the workpiece at this time).
Start the saw. When the saw reaches the maximum
speed, push it forward slowly. Always hold your saw
rmly with both hands when operating.
WORK HINTS FOR YOUR
RECIPROCATING SAW
If your power tool becomes too hot, run it no load for
2-3 minutes to cool the motor. Avoid prolonged usage at
very low speeds.
Always use a blade suited to the material and material
thickness to be cut. The quality of cut will improve as
the number of blade teeth increase. Always ensure
the work-piece is rmly held or clamped to prevent
movement. Support large panels close to the cut line.
Any movement of the material may affect the quality
of the cut. The blade cuts on the upward stroke and
may chip the uppermost surface or edges of your work
piece. When cutting, ensure your uppermost surface
is a non-visible surface when your work is nished.
Feeding too fast signicantly reduces the performance
of the machine and shortens the life of the saw blade.
Always face the good side of the work piece down
to ensure minimum splintering. Only use sharp saw
blades of the correct type.
For pocket cutting (soft materials only) this operation
requires much skill with a saw and must only be carried
out by a competent person.
Warning: The blade teeth are exposed during
this operation, so operate with extreme caution.
Clearly mark the area to be cut. Set the depth of cut on
the saw. Position the saw over the marked area with
the front edge of the base plate resting on the work
surface and cutting guide aligned with marked line
on workpiece. Ensure the blade is not touching but
is close to the work surface. The moving lower guard
must be rotated open by using the lever. Switch on the
saw and gently swing the blade down into the material
but maintain a pivoting force on the front edge of the
base. The moving lower guard can now be released for
normal action of the guard.
MAINTENANCE
Remove the plug from the socket before carrying out
any adjustment, servicing or maintenance.
There are no user serviceable parts in your power
tool. Never use water or chemical cleaners to clean
your power tool. Wipe clean with a dry cloth. Always
store your power tool in a dry place. Keep the motor
ventilation slots clean. Keep all working controls free
of dust. Occasionally you may see sparks through the
ventilation slots. This is normal and will not damage
your power tool.
If the supply cord is damaged, it must be replaced by
the manufacturer, its service agent or similarly qualied
persons in order to avoid a hazard.
