DO NOT let children come into contact with the tool.
Supervision is required when inexperienced operators use
this tool.
• Young children and the infirm. This appliance is not
intended for use by young children or infirm persons
without supervision.
• This product is not intended for use by persons (including
children) suffering from diminished physical, sensory or
mental abilities; lack of experience, knowledge or skills
unless they are supervised by a person responsible for their
safety. Children should never be left alone with this product.
Active Vibration Control (Fig. A)
The active vibration control neutralises rebound vibration from
the hammer mechanism. Lowering hand and arm vibration
allows for more comfortable use for longer periods of time and
extends the life of the unit.
For best vibration control, hold the tool with one hand on the
main handle and the other hand on the side handle
2
Apply just enough pressure so the hammer is approximately
mid-stroke.
The hammer only needs enough pressure to engage the active
vibraton control. Applying too much pressure will not make
the tool drill or chip faster and active vibration control will
not engage.
Torque Limiting Clutch
WARNING: The user must always maintain a firm grip on
the tool when in operation.
The torque limiting clutch reduces the maximum torque
reaction transmitted to the operator in case of jamming of a drill
bit. This feature also prevents the gearing and electric motor
from stalling.
NOTICE: Always turn the tool off before changing torque
control settings or damage to tool may result.
ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. Be sure the
trigger switch is in the OFF position. An accidental start-up
can cause injury.
Selecting the Operating Mode (Fig. C)

Rotary drilling: for screwdriving and for drilling into
