19. Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
20. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tools operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
22. Use the power tool, accessories and tool bits
etc. in accordance with these instructions and in
the manner intended for the particular type of
power tool, taking into account the working con-
ditions and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
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

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.
Hold power tools by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
3.
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.
4.
Be sure the bit is secured in place before opera-
tion.
5.
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.
6.
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.
7.
Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
8.
Hold the tool firmly with both hands.
9.
Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
12. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
13. Do not operate the tool at no-load unnecessarily.
14. 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 scaling chisel or other bit
(bull point, etc.) (Fig. 1 & 2)
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
To install the bit, first attach the dust cover provided to the
bit as shown in Fig. 1.
Then turn the tool retainer in the direction of the arrow
and insert the bit into the tool barrel as far as it will go.
Now turn the tool retainer in the opposite direction to
secure the bit.
To remove the bit, follow the installation procedure in
reverse.
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.
• Do not tape, tie or otherwise secure the trigger in the
"ON" position.
To start the tool, simply pull the trigger. tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop. A speed control screw is provided so
that maximum tool speed can be limited (variable). Turn
the speed control screw clockwise for higher speed, and
counterclockwise for lower speed.
Operation (Fig. 4)
Position the chisel at the location to be scaled, then pull
the trigger. Apply light pressure to the tool. Forcing the
tool will only decrease the tool performance.
