HAMMER SAFETY WARNINGS

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 tool 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 power tool "live" 
and could give the operator an 
electric shock.

ADDITIONAL SAFETY RULES 
FOR HAMMER

1.  Always wear a dust mask.
2.  Safety boots are 
recommended at all times 
especially when using the chisel 
actions.
3.  Proper safety gloves are also 
recommended.
4.  The high torque machine 
should not be used, while 
standing on a ladder.
5.  Do not use damaged or worn 
Chisel bits.
6.  Do not run the machine with 
any part of the casing missing or 
damaged.
7.  Use a detector to localize lines 
in walls with concealed electric, 
water or gas lines. Avoid touching 
live components or conductors.

8.  Before starting to work, always 
check that the chisel properly 
locked in the chuck.
9.  Chisel bits may be flung out 
of the machine accidentally and 
cause serious injury.
10. Vibrations can injure the hand-
arm system. Keep exposure to 
vibrations as short as possible.
When carrying out work, always 
hold the hammer with both hands 
and ensure that you have a stable 
standing position.
