Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and can
be operated on single-phase AC/DC supply. They are
double-insulated in accordance with European Standard
and can, therefore, also be used from sockets without
earth wire.
Safety hints
For your own safety, please refer to enclosed safety
instructions.
ADDITIONAL SAFETY RULES
1. Wear a hard hat (safety helmet), safety glasses
and/or face shield. It is also highly recom-
mended that you wear a dust mask, ear protec-
tors and thickly padded gloves.
2. Be sure the bit is secured in place before opera-
tion.
3. 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.
4. In cold weather or when the tool has not been
used for a long time, let the tool warm up for sev-
eral minutes by operating it under no load. This
will loosen up the lubrication. Without proper
warm-up, hammering operation is difficult.
5. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
6. Hold the tool firmly with both hands.
7. Keep hands away from moving parts.
8. Do not leave the tool running. Operate the tool
only when hand-held.
9. Do not point the tool at anyone in the area when
operating. The bit could fly out and injure some-
one seriously.
10. When chipping into walls, floors or wherever
“live” electrical wires may be encountered, DO
NOT TOUCH ANY METAL PARTS OF THE TOOL!
Hold the tool by the insulated grasping surfaces
to prevent electric shock if you chip into a “live”
wire.
11. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Installing or removing the bit (Fig. 1)
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
With the notched portion on the shank of the bit facing
toward the tool retainer, insert the bit into the tool holder
as far as it will go. Then pull out and turn the tool retainer
180° to secure the bit. After installing, always make sure
that the bit is securely held in place by trying to pull it out.
When installing the scaling chisel, clay spade or rammer,
remove the dust cover from the tool.
Side handle (auxiliary handle) (Fig. 2)
The side handle can be either freely swivelled or secured
at one position for use during tool operation. Just loosen
the nut to swivel the handle freely.
To secure the handle at a fixed position, first loosen the
nut and swing the handle to the desired position for use.
Then tighten the nut firmly. If the set bolt turns together
with the nut when you secure the nut, see that the pro-
jecting portion of the side handle fits into the notch on the
head of the set bolt.
Switch action (Fig. 3)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the “OFF”
position when released.
To start the tool, simply pull the trigger. Release the trig-
ger to stop. For continuous operation, pull the trigger and
then slide down the lock button. To stop the tool from the
locked position, pull the trigger fully, then release it.
Chipping / Scaling / Demolition
Hold the tool firmly with both hands. Turn the tool on and
apply slight pressure on the tool so that the tool will not
bounce around, uncontrolled. Pressing very hard on the
tool will not increase the efficiency.
