Always disconnect the Rotary Hammer from its electrical power supply source before performing any inspection, maintenance, or cleaning procedure. 2. Before each use, inspect the general condition of the Rotary Hammer. Inspect switch, power plug and cord assembly, and extension cord (if used) for damage. Check for loose screws, misalignment, binding of moving parts, broken, cracked, or improper mounting of the chisels. If abnormal noise or vibration occurs, turn off the Rotary Hammer immediately and have the problem corrected before further use. Do not use damaged equipment! Replacing the Carbon Brushes (105) Replacing the Carbon Brushes (105) NOTE: The Rotary Hammer Has a red LED located on the handle that will light up when the Carbon Brushes (105) are worn down and need to be replaced. See Figure 5 below. To replace the Carbon Brushes (105) you must first remove the four screws that attach the Left Tail Cover (96) and the four screws that attach the Right Tail Cover (91). See Page 13. Next remove each Carbon Brush (105) by gently pulling on the wire that it is connected to. Disconnect the Carbon Brush connector and insert the new brushes by bushing them into the Brush House (104). After both Carbon Brushes (105) are inserted, attach the Carbon Brush connector, the Left Tail Cover (96) and the Right Tail Cover (91). See Figure 5 below. Left Tail Cover Left LED Light Figure 5 How to add grease to the gears Every 100 hours of use it is recommended that you add wheel bearing grease to the gears. To get access to the gears, you must remove Crank Case Cover (40) by removing the six machine screws (37). Next rub wheel bearing grease on all the gears in the chamber. Replace the Crank Case Cover (40) using the same machine screws (37) that held it on. See the assembly diagram on page 17 to identify the parts. TROUBLESHOOTING Problem Cause Action Motor doesn’t rotate when switched on. Disrupted power Poor switch contact Worn carbon brushes Check power supply Have switch repaired Replace brushes Overheated gearbox Dull Drill Bit Excessive use Gears need grease Replace or sharpen the Drill Bit Allow tool to cool down Add grease to the gears NOTE: Other than changing or cleaning the carbon brushes, all other internal repairs should be done by a qualified service technician.
