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.
WORK AREA SAFETY
1
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.
ELECTRICAL SAFETY
2
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 is in the offposition 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.
2
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, 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 of dust 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.

Note: Before using the tool, read the instruction book carefully.
INTENDED USE
The machine is intended for sawing wood, plastic, metal, and building
materials while resting firmly on the workpiece. It is suitable for
straight and cur ved cuts. When using the appropriate bimetal saw
blades, it is possible to cut flush to the workpiece surface. The saw
blade recommendations must be observed.
KNOW YOUR RECIPROCATING SAW
vibrafree ™ RECIPROCATING SAW are uniquely designed to
cancel out the saw’s vibration in every load condition. This active
vibration canceling technology makes this saw more comfortable
and easy to use, taking the vibration out of the saw, the workpiece,
your hands and arms, and putting this energy to work sawing and
removing material.

TRIGGER SWITCH (See Fig. A)
Depress the switch to start and release it to stop your tool.
The blade plunger stroke rate can be adjusted from the minimum
to maximum by the pressure you apply to the trigger. Apply more
pressure to increase the speed and release pressure to decrease
speed. ( See Fig. A)

control without positive stops between 1 and 6 according to your
work. Refer to the table to select the proper speed for the workpiece
to be cut. However, the appropriate speed may differ with the type
or thickness of the workpiece. In general, higher speeds will allow
you to cut workpieces faster but the service life of the blade will be
reduced.

TOOL-LESS BLADE FITTING ( See Fig. D, E)
To install the blade, disconnect the saw from power supply. If
necessar y, extend the pivoting blade foot away from the blade clamp
for easier access. Pull the tool-less blade clamp lever (3) up with your
thumb in clock wise direction. (See Fig. D) Insert the blade into the
saw’s blade clamp and make sure that the blade attaches to the blade
pin inside the clamp. Release the blade clamp lever (3) to ensure the
blade is locked securely in place.
Before removing the saw blade, make sure it’s already cooled. To
remove Blade, disconnect saw from power supply. If necessary,
extend the pivoting blade foot away from the blade clamp for easier
access. First, pull the blade clamp lever ( 3 ) up with your thumb, and
then pull the blade out of the blade clamp. (See Fig. E )
Warning: Do not remove the saw blade immediately when
finished your working, you may get burned by the hot blade.
TOOL-LESS FOOT PL ATE ADJUSTMENT (See Fig.F)
5
If you need to reduce the cutting capacity of your tool (depth of cut),
the pivoting foot plate (6 ) may be adjusted as follows.
Press the tool-less foot plate adjusting button (7) on the underside of
the front housing. Slide the pivoting foot plate forward or backwards
to give the required distance from the end of the blade. Release the
pivoting foot plate adjusting button. The pivoting foot plate is now
locked in position but will continue to pivot as it follows the work
surface during the cut. The distance from the front of the foot plate to
the tip of the blade (on the longest part of the cutting stroke) equals
the cutting capacity of the tool.

PENDULUM ACTION CONTROL (See Fig. G)
6
The pendulum action varies the down cutting angle of the blade for
increased cutting efficiency. This can also be adjusted during no load
running.
Do not use excessive blade force when cutting with the pendulum
action.
Warning: Make sure the pendulum setting is “0’ when
using the saw blade teeth facing up.

PENDULUM SETTINGS
0 Thin materials, fine cuts, tight curves.
1 Hard materials (e.g. steel & chipboard ).
2 Thick materials (e.g. wood) & plastics.
3 Fast cuts (e.g. softwood). Cutting in the direction of the wood grain.
FLUSH CUTTING (See Fig. H, I)
7
It is possible to make cuts extremely close to floors, walls and other
difficult areas. Insert the blade shank into the blade clamp with the
blade teeth facing up (opposite to normal working position). This
I
will make cuts closer to the work surface (See Fig. H). Using special
flexible blades insert the blade into the blade clamp with the blade
teeth facing down (normal working position). It will allow flush pipe
cutting ( See Fig. I).
WOOD CUTTING

METAL CUTTING
This saw has different metal cutting capacities depending upon the
type of blade being used and metal being cut.
ALWAY S clamp the work down to prevent it from slipping.
Use a finer blade for ferrous metals and a coarse blade for nonferrous metals.
When cutting thin gauge sheet metals, ALWAYS clamp wood on
both sides of the sheet. This will give you a clean cut without excess
vibration or tearing of the metal.
DO NOT force the cutting blade. Forcing the blade will reduce blade
life and cause the blade to break.
Note: We recommend that you spread a thin film of oil or other
J
K
coolant along the line of cut ahead of the saw. This will allow easier
operation and help extend blade life. When cutting aluminum, use
kerosene.
POCKET CUTTING (Soft materials only) (See Fig. J, K)
10
Mark the pocket or internal hole to be cut out. Insert the special
cutting blade with blade teeth facing down and clamp securely. Angle
the saw so that the back edge of the blade guard is resting on the
L
work surface. Use a slow speed to start the cut to avoid breaking the
blade but increase to correct speed once the cut has started. With
the blade guard held firmly against the work surface, start a slow
but controlled upward swing of the saw. The blade will cut into and
through the material. Always ensure the blade is completely through
the material before cutting the remainder of the pocket.
REPLACING CARBON BRUSHES (See Fig. L)
11
Remove and check the carbon brushes regularly. When they are
worn to length of about 6mm, both new carbon brushes should be
12
replaced at the same time. When changing worn carbon brushes,
use a slotted screwdriver to remove the brush holder caps. Take out
the worn carbon brushes, insert the new ones and make sure the
carbon brushes moving freely in the brush holders. Finally, secure the
brush holder caps.
Work hints for your reciprocating
saw
If your power tool becomes too hot, set the speed to maximum and
run a no load for 2- 3 minutes to cool the motor.
Always ensure the work-piece is firmly held or clamped to prevent
movement.
The pivot foot plate must be held firmly against the material being cut
to reduce saw vibration, blade jumping and blade breakage.
Maintenance
Remove the plug from the socket before carrying out any
adjustment, servicing or maintenance.
Your power tool requires no additional lubrication 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 ser vice agent or similarly qualified persons in order
to avoid a hazard.
