Vibration information
Vibration total values (triax vector sum) determined according to
EN 60745:
Cutting into wood Vibration emission value ah CW= 5 .61m / s2
Uncertainty K=1.5m/s²
Cutting into steel
metal
Vibration emission value ah CM = 11. 4 m / s2
Uncertainty K=1.5m/s²
Warning: The vibration emission value during actual use of the
power tool can differ from the declared value depending on the ways
in which the tool is used dependant on the following examples and
other variations on how the tool is used:
How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained
The use the correct accessory for the tool and ensuring it is sharp and
in good condition.
The tightness of the grip on the handles and if any anti vibration
accessories are used.
And the tool is being used as intended by its design and these
instructions.
This tool may cause hand-arm vibration syndrome if its use is
not adequately managed.
Warning: To be accurate, an estimation of exposure level in
the actual conditions of use should also take account of all parts of
the operating cycle such as the times when the tool is switched off
and when it is running idle but not actually doing the job. This may
significantly reduce the exposure level over the total working period.
Helping to minimise your vibration exposure risk.
ALWAYS use sharp chisels, drills and blades
Maintain this tool in accordance with these instructions and keep well
lubricated (where appropriate)
If the tool is to be used regularly then invest in anti vibration
accessories.
Avoid using tools in temperatures of 100C or less
Plan your work schedule to spread any high vibration tool use across
a number of days.
Accessories
Blade for metal: 150mmx18TPI, BIM 1pc
We recommend that you purchase your accessories from the same
store that sold you the tool. Use good quality accessories marked
with a well-known brand name. Choose the type according to the
work you intend to undertake. Refer to the accessory packaging for
further details. Store personnel can assist you and offer advice.

Additional safety rules for your
reciprocating saw
Always wear a dust mask.
Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory
contacting a “live” wire may make exposed metal parts of the
power tool “live” and could give the operator an electric shock.
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 leaves it unstable and may lead to loss of control.
Always wear safety glasses or eye shields when using the
reciprocating saw. Everyday eyeglasses have only impact-
resistant lenses; they are NOT safety glasses. Following this
rule will reduce the risk of serious personal injury.
Always wear hearing protection during extended periods
of operation. Following this rule will reduce the risk of serious
personal injury.
Keep your hands away from cutting area. Do not reach under
the material being cut because the nearness of the blade to your
hand is hidden from your sight.
Do not use dull or damaged blades. Bent blades can break
easily, or cause kickback.
Remove the plug from the socket before carrying out any
adjustment, servicing or maintenance.
Fully unwind cable drum extensions to avoid potential overheating.
When an extension cable is required you must ensure it has the
correct ampere rating for your power tool and is in a safe electrical
condition.
Ensure your mains supply voltage is the same as indicated on the
rating plate.
Your tool is double insulated for additional protection against a
possible electrical insulation failure within the tool.
Always check walls, floors and ceilings to avoid hidden power
cables and pipes.
After long working period, external metal parts and accessories
could be hot.
Always hold the saw firmly with both hands when operating.
Only withdraw the blade from the cut when the blade has been
stopped moving.
The pivoting blade foot must be held firmly against the material
being cut to reduce saw vibration, blade jumping and blade
breakage.
Before cutting, check the cutting line is free of nails, screws, etc.
If possible, ensure the work-piece is firmly clamped to prevent
movement.
Never stop the cutting blade by applying side pressure to the blade.
Warning: Some dust particles created by power sawing,
contain 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 and cement and other masonry
products.
•Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending upon how
often you do this type of work. To reduce your exposure to these
chemicals:
•Work in a well-ventilated area.

Operating instructions
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 curved 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)
VARIABLE SPEED DIAL (See Fig. B)
Adjust the variable speed dial to increase or decrease the speed
according to the material, material thickness and blade specification
to be used. Refer to the table to select the proper speed for the
workpiece to be cut. In general, higher speeds will allow you to cut
workpieces faster but the service life of the blade will be reduced.

Note:
• If the tool is operated continuously at low speeds for a long period
of time, the operation life of the motor will be reduced.
• The variable speed control can be turned only as far as 6 and back
to 1. Do not force it past 6 or 1, or the speed adjusting function may
no longer work.
HAND GRIP AREAS (See Fig. C)
Always hold your saw firmly with both hands when operating.
TOOL-FREE BLADE FITTING (See Fig. D, E)
To install the blade, disconnect the saw from power supply. If
necessary, extend the pivoting blade foot away from the blade clamp
for easier access. Pull the tool-free blade clamp lever (3) up with your
3
4
10
thumb in clockwise 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: Blade teeth are very sharp. For best cutting results
ensure you use a blade suited to the material and cut quality you
need.
TOOL-FREE FOOT PLATE ADJUSTMENT (See Fig.F)
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-free 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.
Note: The pivoting blade foot must be held firmly against the material
being cut to reduce saw vibration, blade jumping and blade breakage.
PENDULUM ACTION CONTROL (See Fig. G)
The pendulum action varies the down cutting angle of the blade for
increased cutting efficiency. This can also be adjusted during no load
5
6
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)
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
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
Always ensure the work-piece is firmly clamped to prevent
movement. For easier control use low speed to start cutting, then
increase to the correct speed.
METAL CUTTING
This saw has different metal cutting capacities depending upon the
type of blade being used and metal being cut.
ALWAYS clamp the work down to prevent it from slipping.

11
Use a finer blade for ferrous metals and a coarse blade for non-
ferrous 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
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)
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
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)
Remove and check the carbon brushes regularly. When they are
worn to length of about 6mm, both new carbon brushes should be
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 service agent or similarly qualified persons in order
to avoid a hazard.
