PRODUCT FEATURES Note: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagrams on page 17. 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 adding accessories or performing maintenance on the tool. OIL CAP(45) SLIDER(4) FRONT CAP(1) KNOB(105) AUXILIARY HANDLE(104A) POWER SWITCH(66) VARIABLESPEED CONTROL(72) FIGURE E 1. Oil Cap (45): Prior to the Demolition Hammer’s first use, remove the Oil Cap and check to make sure the tool is properly filled with grease. If necessary, fill the tool with approximately 1-1/4 ounces of #3 Lithium-based grease (not included). Then, replace the Oil Cap. Thereafter, replace the grease at the end of every 70 to 80 hours of tool use. (See Figure E.) Power Switch (66): 2. The Demolition Hammer is switched “ON” by the slide switch located in the rear Handle (62). To turn the tool “ON”, slide the switch to the right. To turn the tool “OFF”, slide the switch to the left. (See Figure E.) REV10d Variable Speed Control (72): 3. The Demolition Hammer is equipped with a Variable Speed Control Dial. The impact rate (BPM) and rotating speed (RPM) can be varied according to the type of work being performed by setting the Variable Speed Control Dial to the selected setting: 1-2-3-4-5-6 (“1” Being the lowest. “6” Being the highest.) The Variable Speed Control Dial may be adjusted while the Motor is running with the tool free from work, allowing the operator to adjust the impact rate and rotating speed according to the actual application. (See Figure E.) Auxiliary Handle (104A) and Knob (105): 4. The Demolition Hammer must be supported with the Auxiliary Handle, which can be swiveled 360 degrees. To reposition and/or swivel the Auxiliary Handle, loosen the Knob. Move the Auxiliary Handle to the desired position along the barrel of the tool and firmly retighten the Knob. (See Figure E.)

Front Cap (1) and Slider (4): To install a Chisel (106, 107), clean the insert shank end of the chisel to remove any debris. Then, lightly grease the shank with a light oil or grease. Insert the Chisel into the Slider through the Front Cap, while twisting and pushing inward until the Chisel locks into place. Pull outward on the Chisel to make sure it is locked into the Slider. (See Figure F.) OPERATING INSTRUCTIONS WARNING! Always wear ANSI-approved safety impact eye glasses and a full face shield when using the Demolition Hammer. Also wear heavy duty steel-toe boots, hearing protection, dust mask or respirator, and heavy duty work gloves. Install a Chisel (106, 107) as previously discussed. 1. (See Figure F.) Make sure the Power Switch (66) is in its “OFF” position. Then, connect the 2. Power Cord & Plug (70) to the nearest 120 volt, grounded electrical outlet. (See Figure E.) REV10d Grasp the Demolition Hammer firmly by its rear Handle (62) and Auxiliary Handle 3. (104A). Then, turn the Power Switch (66) to its “ON” position to begin work. IMPORTANT: 4. 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.) For the best penetration rates in concrete, run the Demolition Hammer with 5. a steady pressure but do not use excessive force as this will decrease the efficiency of the tool. If necessary, adjust the Variable Speed Control Dial (72) to increase the tool’s 6. cutting efficiency. (See Figure E.) When finished using the Demolition Hammer, turn the Power Switch (66) to its 7. “OFF” position. Then, unplug the tool from its electrical outlet. (See Figure E.) Allow the Chisel (106, 107) to completely cool. Then, pull and hold the locking 8. Slider (4) backward and pull the Chisel forward. The Chisel should be cleaned after removing. (See Figure F.) Make sure to store the Demolition Hammer in a clean, dry, safe location out of 9. reach of children and other unauthorized people. INSPECTION, MAINTENANCE, AND CLEANING 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. Before each use,1. 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. To replace the Motor Carbon Brushes: 2. It may b...
