GENERAL POWER TOOL SAFETY WARNINGS

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 THE WARNINGS REFERS
TO YOUR MAINS-OPERATED JIGSAW.

Save all warnings and instructions for future reference.

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 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.

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.

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 cable. Never use the cable 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 cable 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 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, safety shoes, 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 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.

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 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 tools.

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]

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) SERVICING

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.

SPECIFIC WARNINGS FOR JIGSAWS

1. ONLY sharp saw blades in per fect working condition should be used;
cracked or bent saw blades should be discarded and replaced at once.

2. ALWAYS ensure that the blade is securely fixed.

3. ALWAYS use the appropriate blade for the material being cut.

4. ALWAYS use a cooling agent when cutting metals, i.e. cutting oil.

5. ALWAYS allow sufficient clearance beneath the work to ensure the blade
does not come into contact with the floor, table etc.

6. ALWAYS check for hidden electrical wires or water pipes etc.

7. ALWAYS keep the mains cable well away from the machine and ensure an
adequate electrical supply is close at hand so that the operation is not
restricted by the length of the cable.

8. When cutting wood, ensure any nails have been removed beforehand.
Nails will damage the wood saw blade.

9. NEVER allow the ventilation slots in the machine to become blocked.

10. NEVER attempt to stop the saw blade with your fingers.

11. NEVER put the saw down on a table or work bench unless switched off. The
saw blade will keep running briefly after the tool has been switched off.

12. DO NOT cut material above the specified thickness.

13. DO NOT cut through walls or cavities before checking for hidden electrical
wires or water pipes etc.

14. DO NOT touch the blade immediately after use, allow time for it to cool.

15. DO NOT attempt to saw extremely small workpieces.

16. Wherever possible, use clamps and vices to fasten the workpiece securely.

INSTALLING/CHANGING BLADES

1. Use only jigsaw blades with the
correcting T-shank.

2. This jigsaw comes with a
convenient tool-less quick release
blade retainer. To install a blade,
use your thumb to pull the lever
counterclockwise to open the
blade retainer (A).

3. With the blade teeth facing
forward, insert the blade (B) into
the blade retainer as far as it will
go. Make sure that the back edge
of the blade sits against the blade
support roller (C). Move the spring-loaded lever (A) to insert the blade,
then pull on the blade until the blade retainer snaps shut and secures the
blade.

• Take care never to use cracked, blunt or damaged blades.

OPERATION

CAUTION: DO NOT PLUG INTO THE MAINS UNLESS YOU HAVE ENSURED
THE JIGSAW IS SWITCHED OFF. TO DO THIS, SQUEEZE THE TRIGGER FULLY
UPWARDS, THEN RELEASE IT. THE TRIGGER IS LOCATED UNDER THE GRIP.

TURNING ON AND OFF

1. To start the jigsaw, squeeze the
trigger (B). Wait until the blade is
running at speed before
attempting to cut the workpiece.

CONTINUOUS OPERATION

2. To stop the jigsaw if the lock-on button is used, squeeze the trigger fully in,
then release it and the motor will stop.

ADJUSTING THE SPEED

The jigsaw speed can be adjusted
between 0 and 3,000 strokes per
minute by turning the speed selector
(A).

• The selector is marked 1 (lowest

speed) to 6 (full speed).

In general, higher speeds will allow
you to cut workpieces faster but the
service life of the blade will be
reduced.

DUST COLLECTION

The jigsaw is provided with a dust
extract connection, (A) where a
vacuum extractor may be
connected to the rear of the
machine.

Please note however, that this does
not preclude the user from wearing a
face mask to prevent the inhalation
of dust particles.

Connect the vacuum extractor port
to an extract system wherever
possible.

ADJUSTING THE SOLE PLATE FOR BEVEL CUTTING

The sole-plate (A) can be tilted so
that bevels of up to 45° may be cut
(left or right).

1. Loosen the two socket head
screws (B) under the body of the
saw using the hex key supplied,
before tilting the sole plate to the
desired angle and re-tightening
the screws.

2. Use the angle marks (C) as a
guide to the angle achieved. The
marks indicate the tilt angle from
0 to 45 degrees.

CUTTING PROCEDURES

WARNING: IF THE CUTTING OPERATION IS DUSTY, WE RECOMMEND THAT
YOU WEAR A DUST MASK.

USING THE JIGSAW

1. Ensure that the workpiece being cut is securely held in place and that the
cut line is clearly marked.

2. Place the sole-plate on the workpiece and squeeze the trigger to run the
jigsaw up to its working speed before letting the blade touch the cut line.

3. To make your cut, move the saw slowly forward along the cutting line
taking care that the blade is vertical (unless making an angled cut) and
correctly positioned in relation to the cut line.

4. Let the blade work forward, ensuring the sole plate is flush with the
workpiece.

5. Do not press too hard. If the saw slows down as it is cutting, apply less
pressure.

6. Adjust the speed control to suit the material being cut. The optimum speed
will be determined with practice.

7. When sawing do not put unnecessary pressure on the blade and avoid
applying lateral pressure.

8. Take extra care when cutting curves - move the blade slowly to avoid stress
on the blade.

9. Check that any previously used timber being sawn does not contain any
nails or other metal objects which would damage the blade.

10. Ensure the blade is not striking on anything below the workpiece and that
the power cable is well away from the moving blade before starting the
saw.

• If cutting out an aperture, it will be necessary to drill a suitably sized

hole in the workpiece for use as a starting point.

• Note that the blade should emerge from the workpiece at every

point of the cut.

11. Allow the saw to come to a complete stop before putting it down.

12. To prevent accidents, turn off the saw and disconnect the power supply
after use. Clean, then store the saw indoors out of the reach of children.
