SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with product (gained
from repeated use) replace strict adherence to ham-
mer 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. Contact
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 loca-
tions.
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 imme-
diately 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.

Installing side grip (auxiliary handle)
(Fig. 2)
The side grip swings around to either side, allowing easy

by turning it counterclockwise, swing it to the desired posi-
tion and then tighten it by turning clockwise.

been returned to the original position and the bit does
not come off the tool.
