DEMOLITION 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 WARNINGS

1.  Ensure that the power source to be utilized conforms 

to the power requirements speci

fi

 ed on the product 

nameplate.

2.  Ensure that the power switch is in the OFF position. 

If the plug is connected to a receptacle while the power 

switch is in the ON position, the power tool will start 

operating immediately, which could cause a serious 

accident.

3.  When the work area is removed from the power source, 

use an extension cord of su

ffi

  cient thickness and rated 

capacity. The extension cord should be kept as short as 

practicable.

4. Do not touch the bit during or immediately after 

operation. The bit becomes very hot during operation 

and could cause serious burns.

5.  Before starting to break, chip into a wall, 

fl

 oor or ceiling, 

thoroughly con

fi

 rm that such items as electric cables or 

conduits are not buried inside.
