Intended Use
Your heavy-duty rotary hammer is designed for professional
masonry drilling and chiseling applications.
DO NOT use under wet conditions or in the presence of
flammable liquids or gases.
Your heavy-duty rotary hammer is a professional power tool.
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.
Soft Start Feature
The soft start feature allows the tool to accelerate slowly, thus
preventing the drill bit from walking off the intended hole
position when starting.
The soft start feature also reduces the immediate torque
reaction transmitted to the gearing and the operator if the
hammer is started with the drill bit in an existing hole.
Vibration Control System
For best vibration control, hold the tool as described in Proper
Hand Position and apply just enough pressure so the damping
device on the main handle is approximately mid stroke.
The active vibration control neutralises rebound vibration from
the hammer mechanism. Lowering hand and arm vibration,
it allows more comfortable use for longer periods of time and
extends the life of the unit.
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.
Lock-On Switch (Fig. A)
Chipping mode only
The lock-on switch 8 offers increased comfort in extended use
applications. To lock the tool on, depress the lock-on switch
while the tool is running. The tool will continue to run after the
switch is released. To unlock and turn off the tool, depress and
release the switch.
Electronic Speed and Impact Control (Fig. A)
The electronic speed and impact control allows the use of
smaller drill bits without the risk of bit breakage, hammerdrilling
into light and brittle materials without shattering and optimal
tool control for precise chiseling.
To set the electronic speed and impact control dial
9 , turn the
dial to the desired level. The higher the number, the greater
the speed and impact energy. Dial settings make the tool
extremely flexible and adaptable for many different appli cations.
The required setting depends on the bit size and hardness of
material being drilled.
•
When chiselling or drilling in soft, brittle materials or when
minimum break-out is required, set the dial to a low setting;
• When breaking or drilling in harder materials, set the dial to
a high setting.
Overload Clutch
In case of jamming of a drill bit, the drive to the drill spindle is
interrupted. Because of the resulting forces, always hold the
tool with both hands and take a firm stance. After the overload,
release and depress the trigger to re-engage drive.
