Service
23. Have your power tool serviced by a qualified
repair person using only identical replacement
parts.
This will ensure that the safety of the power
tool is maintained.
24. Follow instruction for lubricating and changing
accessories.
25. Keep handles dry, clean and free from oil and
grease.
SPECIFIC SAFETY RULES
GEB004-2
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to hammer safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious personal injury.
1.
Wear ear protectors.
Exposure to noise can cause
hearing loss.
2.
Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
3.
Hold tools by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord.
Con-
tact with a “live” wire will make exposed metal parts
of the tool “live” and shock the operator.
4.
Wear a hard hat (safety helmet), safety glasses
and/or face shield. Ordinary eye or sun glasses
are NOT safety glasses. It is also highly recom-
mended that you wear a dust mask and thickly
padded gloves.
5.
Be sure the bit is secured in place before opera-
tion.
6.
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.
7.
In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper warm-
up, hammering operation is difficult.
8.
Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
9.
Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
13. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
14. Do not operate the tool at no-load unnecessarily.
15. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
OPERATING INSTRUCTIONS
Installing or removing the bit (Fig. 1)
CAUTION:
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.
Side handle (auxiliary handle) (Fig. 2)
The side handle can be either freely swiveled 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.
• Switch can be locked in “ON” position for ease of oper-
ator comfort during extended use. Apply caution when
locking tool in “ON” position and maintain firm grasp on
tool.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop. For continuous operation, pull
the switch trigger and then slide down the lock button. To
stop the tool from the locked position, pull the switch trig-
ger fully, then release it.
Chipping / Scaling / Demolition (Fig. 4)
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.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes (Fig. 5, 6 & 7)
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced. Keep the carbon brushes
clean and free to slip in the holders. Both carbon brushes
should be replaced at the same time. Use only identical
carbon brushes.
• Use a screwdriver to remove the holder cap plates.
• Use a screwdriver to remove the brush holder caps.
Take out the worn carbon brushes, insert the new ones
and secure the brush holder caps.
• Reinstall the holder cap plates firmly
