CORDLESS ROTARY HAMMER
SAFETY WARNINGS
Safety instructions for all operations
Wear ear protectors. Exposure to noise can
1.
cause hearing loss.
2. Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
3. Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting accessory may contact hidden wir-
ing. Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
Safety instructions when using long drill bits with
rotary hammers
1. Always start drilling at low speed and with the
bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate
freely without contacting the workpiece, resulting
in personal injury.
2. Apply pressure only in direct line with the bit
and do not apply excessive pressure. Bits can
bend, causing breakage or loss of control, result-
ing in personal injury.
Additional safety warnings
1. 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 recom-
mended that you wear a dust mask and thickly
padded gloves.
Be sure the bit is secured in place before
2.
operation.
3. 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.
In cold weather or when the tool has not been
4.
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 difficult.
5. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.
6. Hold the tool firmly with both hands.
Keep hands away from moving parts.
7.
8. Do not leave the tool running. Operate the tool
only when hand-held.
9. Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
10. Do not touch the bit, parts close to the bit, or
workpiece immediately after operation; they
may be extremely hot and could burn your
skin.
11. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.
12. Always be sure that the tool is switched
off and the battery cartridge and the bit are
removed before handing the tool to other
person.
13. Before operation, make sure that there is no
buried object such as electric pipe, water pipe
or gas pipe in the working area. Otherwise, the
drill bit/chisel may touch them, resulting an electric
shock, electrical leakage or gas leak.
14. Do not operate the tool at no-load
unnecessarily.

Important safety instructions for
battery cartridge
1. Before using battery cartridge, read all instruc-
tions and cautionary markings on (1) battery
charger, (2) battery, and (3) product using
battery.
2. Do not disassemble or tamper with the battery
cartridge. It may result in a fire, excessive heat,
or explosion.
3. If operating time has become excessively
shorter, stop operating immediately. It may
result in a risk of overheating, possible burns
and even an explosion.
4. If electrolyte gets into your eyes, rinse them
out with clear water and seek medical atten-
tion right away. It may result in loss of your
eyesight.
5. Do not short the battery cartridge:
(1) Do not touch the terminals with any con-
ductive material.
(2) Avoid storing battery cartridge in a con-
tainer with other metal objects such as
nails, coins, etc.
(3) Do not expose battery cartridge to water
or rain.
A battery short can cause a large current
flow, overheating, possible burns and even a
breakdown.
6. Do not store and use the tool and battery car-
tridge in locations where the temperature may
reach or exceed 50 °C (122 °F).
7. Do not incinerate the battery cartridge even if
it is severely damaged or is completely worn
out. The battery cartridge can explode in a fire.
