basic safety precautions should always
be followed to reduce the risk of fire,
electric shock and personal injury.
Read all these instructions
before attempting to operate this
product. Save these instructions
for future reference.
1. KEEP WORK AREA CLEAR. Cluttered
areas and benches invite injuries.
2. CONSIDER WORK AREA
ENVIRONMENT. Do not expose tools
to rain. Do not use tools in damp or
wet locations. Keep work area well lit.
Do not use tools in the presence of
ammable liquids or gases.
3. GUARD AGAINST ELECTRIC SHOCK.
Avoid body contact with earthed or
grounded surfaces.
4. KEEP OTHER PEOPLE AWAY. Do
not let others, especially children, not
involved in the work touch the tool or
the extension lead and keep them away
from the work area.
5. STORE IDLE TOOLS. When not in use,
tools should be stored in a dry locked-
up place, out of reach of children.
6. DO NOT FORCE THE TOOL. It will do
the job better and safer at the rate for
which it was intended.
7. USE THE RIGHT TOOL. Do not force
small tools to do the job of a heavy
duty tool. Do not use tools for purposes
not intended; for example do not use
circular saws to cut tree limbs or logs.
8. DRESS PROPERLY. Do not wear loose
clothing or jewellery, they can be caught
in moving parts. Nonskid footwear is
recommended when working outdoors.
Wear protective hair covering to contain
long hair.
9. USE PROTECTIVE EQUIPMENT. Use
safety glasses. Use face or dust mask if
cutting operations create dust.
10. CONNECT DUST EXTRACTION
EQUIPMENT. If devices are provided
2
breakage of parts, mounting and any
other conditions that may affect its
operation. A guard or other part that is
damaged should be properly repaired
or replaced by an authorised service
centre unless otherwise indicated in this
instruction manual. Do not use the tool if
the switch does not turn it on and off.
21.
WARNING. The use of any accessory or
attachment other than one recommended
in this instruction manual may present a
risk of personal injury.
22. HAVE YOUR TOOL REPAIRED BY
A QUALIFIED PERSON. This electric
tool complies with the relevant safety
rules. Repairs should only be carried
out by a qualied person using original
spare parts, otherwise this may result in
considerable danger to the user.
23. THROUGH POOR CONDITIONS OF
THE ELECTRICAL MAINS, shortly
voltage drops can appear when starting
the EQUIPMENT. This can inuence
other equipment (e.g. blinking of a
lamp). If the MAINS-IMPEDANCE
Zmax < 0.34 OHM, such disturbances
are not expected.
24. DO NOT USE SAW BLADES
MANUFACTURED FROM HIGH
SPEED STEEL.
25. KEEP THE FLOOR AREA AROUND
THE MACHIN LEVEL, well maintained
and free of loose material e.g. chips
and cutoffs.
26. USE CORRECTLY SHARPENED SAW
BLADES. Observe the maximum speed
marked on the saw blade. Ensure that
the machine is always xed to a bench,
whenever possible.
Additional Safety Rules
For Demolition Hammer
1. Hold tools by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring
or its own cord. Contact with “live” wire
will make exposed metal parts of the tool
“live” and shock the operator.
2. Wear ear protectors when using the
tool for extended periods. Prolonged
exposure to high intensity noise can
cause hearing loss.
3. Wear a hard hat (safety helmet), safety
glasses and/or face shield. Ordinary
eye or sun glasses are NOT safety
glasses. It is also highly recommanded
that you wear a dust mask and thickly
padded gloves.
4. Be sure the bit is secured in place
before operation.
5. Under normal operation, the tool is
designed to produce vibration. The
screws can come loose easily, causing a
breakdown or accident. Check tightness
of screws carefully before operation.
6. In cold weather or when the tool has not
been used for a long time, let the tool
warm up for a while by operating it
under no load. This will loosen up the
lubrication. Without proper warm-up,
hammering operation is difcult.
7. Always be sure you have a rm footing.
Be sure no one is below when using the
tool in high locations.
8. Hold the tool rmly with both hands.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate
the tool only when hand-held.
11. Do not point the tool at any one in the
area when operating. The bit could y
out and injure someone seriously.
12. Do not touch the bit or parts close to
the bit immediately after operation; they
may be extremely hot and could burn
your skin.
13. Some material contains chemicals which
may be toxic. Take caution to prevent
dust inhalation and skin contact. Follow
material supplier safety data.
WARNING! DO NOT let comfort or
familiarity with product (gained from
repeated use). Replace strict adherence
to hammer safety rules. If you use this
tool unsafely or incorrently, you can
suffer serious personal injury.
