1.Install a Chisel (106, 107) as previously discussed. (See Figure F.)

2.Make sure the Power Switch (66) is in its “OFF” position. Then, connect the Power Cord & Plug (70) to the nearest 120 volt, grounded electrical outlet.

(See Figure E.)

3.Grasp the Demolition Hammer firmly by its rear Handle (62) and Auxiliary Handle (104). Then, turn the Power Switch (66) to its “ON” position to begin work.

IMPORTANT: This Demolition Hammer requires a short period of time to warm up. Depending on the room temperature, this time may vary from approximately

15 seconds (at 90 degrees Fahrenheit) to 2 minutes (at 32 degrees Fahrenheit). A new Hammer requires a break-in period before full performance is

realized. This period may require up to 5 hours operation. (See Figure E.)

4.For the best penetration rates in concrete, run the Demolition Hammer with a steady pressure but do not use excessive force as this will decrease the efficiency of the tool.

5.If necessary, adjust the Variable Speed Control Dial (72) to increase the tool’s cutting efficiency. (See Figure E.)

6.When finished using the Demolition Hammer, turn the Power Switch (66) to its “OFF” position. Then, unplug the tool from its electrical outlet. (See Figure E.)

7.Allow the Chisel (106, 107) to completely cool. Then, pull and hold the locking Slider (4) backward and pull the Chisel forward. The Chisel should be cleaned after removing. (See Figure F.)

8.Make sure to store the Demolition Hammer in a clean, dry, safe location out of reach of children and other unauthorized people.

INSPECTION, MAINTENANCE, AND CLEANING

1. CAUTION! Always make sure the Power Switch (66) of the Demolition Hammer is in its “OFF” position and the tool is unplugged from its electrical outlet prior to performing any inspection, maintenance, or cleaning.

2.Before each use, inspect the general condition of the Demolition Hammer. Check for loose screws, misalignment or binding of moving parts, cracked or broken parts, damaged electrical wiring, and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, have the problem corrected before further use. Do not use damaged equipment.
