wiring or its own cord.

 Cutting accessory 

contacting a "live" wire may make exposed metal 
parts of the power 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. 

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.

instruction manual may cause serious personal 
injury.
