LONG DURATION OPERATION
If the machine happens to fall out of your hand
during long duration operation, it will not au-
tomatically shut off. In this situation, imme-
diately pull out the power plug and turn the
machine off.
To ensure a safe long duration operation:
• Hold the machine securely at all times.
• Always keep one finger on the on/off button
to be able to turn it off quickly.
For long duration operation, you can push the
lock-on button once, (the on/off switch must
be pressed for this). The machine will stay on
until the on/off switch is pushed quickly once
again and release the lock-on button.
SETTING THE ROTATION SPEED
By pressing the on/off switch, you can set the
rotation speed during idle operation. The op-
timal rotation speed depends on the material
drilled, the operation mode, and the inserted
drill.
Light pressure on the on/off button:
Low rotation speed is intended for:
Small/short screws, soft working materials.
Greater pressure on the on/off button: higher
rotation speed, designated for: large/long
screws, hard working materials.
NOTE: To prevent the cracking of drill holes
(e.g. when drilling tiles), drill holes first with
low rotation speed and then increase it. The
drill is then easier to control and will not slip.
SELECTING THE ROTATION DIRECTION
• Do not set the left/right spin selector during
drilling.
• The rotation direction is always according to
the switch position.
• Switch position R:
Right-rotation/forward/clockwise. To drill and
to screw in screws, push the right/left revers-
ible spin selector all the way to the right.
• Switch position L:
Left-rotation/backward/counter-clockwise.
To loosen or pull out screws and nuts, the right/
left reversible spin selector to the left.
COOLING THE MOTOR
If the motor has intensely overheated, allow
it to run idle for 2 to 3 minutes on maximum
rotation speed.
MAINTENANCE
WARNING: Before each use, inspect the
hammer drill, ON/OFF trigger switch, and cord
for any damaged, missing, or worn parts. Check
for loose screws, misalignment or binding of
moving parts, or any other condition that may
affect the operation. If abnormal vibration or
noise occurs, turn the tool off immediately, and
have the problem corrected before further use.
WARNING: Before cleaning or perform-
ing any maintenance, the tool should be
unplugged from the power supply. Using com-
pressed air may be the most effective cleaning
method.
Always wear safety goggles when cleaning
tools with compressed air.
WARNING: Do not let brake fluid, gasoline,
petroleum-based products, penetrating oil,
etc., come in contact with plastic parts. These
substances contain chemicals that can damage,
weaken or destroy plastic.
WARNING: Check extension cords before
each use. If damaged, replace immediately.
Never use tool with a damaged cord.
WARNING: To ensure safety and reliability,
all repairs should be performed by a qualified
service technician.
