Do not expose power tools to rain or wet
conditions. Water entering power tool will
increase the risk of electric shock.
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.
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.
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.
Power tool use and care
a
18. 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.
19. 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.
20. 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.
8.
9.
21. 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.
22. 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.
23. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
24. 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.
10. Use of power supply via a RCD with a rated
residual current of 30mA or less is always
recommended.
Personal safety
11. 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.
12. 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.
13. 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.
14. 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.
Service
25. 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.
26. Follow instruction for lubricating and
changing accessories.
15. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
16. 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.
17. 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.
27. Keep handles dry, clean and free from oil and
grease.

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.
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 recommended that you wear a dust
mask and thickly padded gloves.

1. Lock button
2. Switch trigger
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
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.
Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.

CAUTION:
WARNING:
•
•
Always check the direction of rotation before
operation.
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this
instruction manual may cause serious personal
injury.
Use the reversing switch only after the tool comes
to a complete stop. Changing the direction of
rotation before the tool stops may damage the tool.
When you operate the tool in counterclockwise
rotation, the switch trigger is pulled only halfway
and the tool runs at half speed. For
counterclockwise rotation, you cannot push in the
lock button.
•
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the
position (A side) for clockwise rotation or to the
4
position (B side) for counterclockwise rotation.
For drilling in wood, metal or plastic materials, depress
the lock button and rotate the action mode changing

CAUTION:
Torque limiter
•
Always set the knob fully to your desired mode
symbol. If you operate the tool with the knob
positioned half-way between the mode symbols,
the tool may be damaged.
The torque limiter will actuate when a certain torque level is
reached. The motor will disengage from the output shaft.
When this happens, the bit will stop turning.
•
•
Do not rotate the action mode changing knob when
the tool is running under load. The tool will be
damaged.
To avoid rapid wear on the mode change
mechanism, be sure that the action mode changing
knob is always positively located in one of the three
action mode positions.
CAUTION:
•
•
As soon as the torque limiter actuates, switch off
the tool immediately. This will help prevent
premature wear of the tool.
Hole saws cannot be used with this tool. They tend
to pinch or catch easily in the hole. This will cause
the torque limiter to actuate too frequently.

Never use "rotation with hammering" when the drill
chuck assembly is installed on the tool. The drill
chuck assembly may be damaged.
Also, the drill chuck will come off when reversing
the tool.
Pressing excessively on the tool will not speed up
the drilling. In fact, this excessive pressure will only
serve to damage the tip of your bit, decrease the
tool performance and shorten the service life of the
tool.
There is a tremendous twisting force exerted on the
