OPERATING INSTRUCTIONS

  Read the ENTIRE IMPORTANT 

SAFETY INFORMATION 

section at the beginning of this 

manual including all text under 

subheadings therein before set 

up or use of this product.

Tool Set Up

 

TO PREVENT 

SERIOUS INJURY 

FROM ACCIDENTAL 

OPERATION: Turn the Power 

Switch of the tool off and unplug 

the tool from its electrical outlet 

before adjusting tool or installing 

accessories.

Work Piece and Work Area Set Up

1.  Designate a work area that is clean 

and well-lit.  The work area must 

not allow access by children or pets 

to prevent distraction and injury.

2.  Route the power cord along a safe 

route to reach the work area without 

creating a tripping hazard or exposing 

the power cord to possible damage.  

The power cord must reach the work 

area with enough extra length to 

allow free movement while working.

3.  Secure loose work pieces using 

a vise or clamps (not included) to 

prevent movement while working.

4.  There must not be objects, such 

as utility lines, nearby that will 

present a hazard while working.

Mounting Tool Bits and 

Locking Side Handle

1. 

WARNING! 

Before installing new bit, 

verify Demolition Hammer is unplugged.

2.  Pull out and turn Locking Lever (73A) 

either clockwise or counterclockwise.

3.  Insert the shank portion of the 

chisel 1″ into the Retainer (70A).

4.  Slide Locking Lever back into Retainer.
5.  Pull chisel to verify it is secure.
6.  The Side Handle (91) can be loosened 

and readjusted to be either above or 

under housing.  To adjust its position, 

loosen the Hex Bolt (93A) and slide 

the Side Handle to desired position.  

Retighten the Hex Bolt until the Side 

Handle is fastened securely into place.

General Operating Instructions

1.  Once the chisel is installed and the Side 

Handle set in the desired position, set 

the tip of the bit against the work area.

2.  Place one hand on the Side 

Handle and the other hand around 

the Main Handle (80A).

3.  Press the Trigger Switch (79D) to 

activate the Demolition Hammer.

4. 

WARNING! 

Once activated, do not 

press, bear down or thrust forcibly 

against the work surface.  Hold the 

Demolition Hammer with just enough 

pressure so that the tool’s own 

weight supplies the needed force. 

5. 

NOTE:

 If the Demolition Hammer has 

not been used for a long period of time 

or is being used in low temperatures, 

keep the tool running for about five 

minutes to allow for warm-up. Make 

sure the Trigger Switch properly 

actuates when pressed and that the 

tool turns off when its released.

6.  When work is complete, 

release the Trigger Switch.
