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 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.
e) 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.
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 a power tool while you are tired
or under the influence of drugs, alcohol or
medication.

ROTARY HAMMER SAFETY
WARNINGS
Safety instructions for all operations
1. Wear ear protectors
Exposure to noise can 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 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.
Safety instructions when using long drill bits with
rotary hammers
4. 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.
5. Apply pressure only in direct line with the bit and do
not apply excessive pressure.
Bits can bend causing breakage or loss of control,
resulting in personal injury.
ADDITIONAL SAFETY WARNINGS
1. Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Ensure that the power switch is in the OFF position.

REACTIVE FORCE CONTROL
This product is equipped with a Reactive Force Control
(RFC) feature that reduces jerking of the tool body.
If the tool bit is suddenly overburdened, any jerking of the
tool body is reduced by activation of the slip clutch or by
stopping of the motor by the sensor built into the tool body.
If the motor is stopped because of overburdening detection
by the controller, the Display lamp will blink while the switch
is pulled. In addition, the lamp will continue blinking for
approximately three seconds after the switch is released.
The motor will remain stopped while the lamp is blinking.
(Fig. 16)
Because the RFC feature may not activate or its performance
may be insufficient depending on the working environment
and conditions, be careful not to suddenly overburden the
tool bit and hold power tool firmly while operating.
●Possible causes of sudden overburdening
Tool bit biting into material
Impact against nails, metal or other hard objects
Tasks involving prying or any excess application of
pressure, etc.
Also, other causes include any combination of the
aforementioned.
●When the reactive force control (RFC) is triggered
When the RFC is triggered and the motor stops, turn
offthe tool’s switch and remove the cause of the
overburdening before continuing operation.
