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. Use auxiliary handle(s), if supplied with the 
tool. Loss of control can cause personal injury. 
3. Hold power tools by insulated gripping 
surfaces, when performing an operation where 
the cutting accessory may contact hidden 
wiring or its own cord. Cutting accessory 
contacting a "live" wire may make exposed metal 
parts of the tool "live" and could give the operator 
an electric shock. 
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 recommended that you wear a dust 
mask and thickly padded gloves. 
5. Be sure the bit is secured in place before 
operation. 
 
 
 
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 someone 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.
