MAINTENANCE AND INSPECTION

WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection.

1.Inspecting the drill bits

Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace the drill bit with a new one or resharpening without delay when abra- sion is noted.

2.Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tight- ened. Should any of the screws be loosened, retighten them immediately.

WARNING: Using this rotary hammer with loosen screws is extremely dan- gerous.

3.Maintenance of the motor

The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

4.Inspecting the carbon brushes

For your continued safety and electrical shock protection, carbon brush inspec- tion and replacement on this tool should ONLY be performed by a HITACHI AU-

THORIZED SERVICE CENTER.

5.How to replace grease

Low viscosity grease is applied to this rotary hammer so that it can be used for a long period without replacing the grease. Please contact the nearest autho- rized service center for grease replacement when any grease is leaking from a loosened screw. Further use of the rotary hammer despite the grease shortage causes seizure to reduce the service life.

CAUTION: A specific grease is used with this machine, therefore, the normal performance of the machine may be badly affected by use of other grease. Please be sure to let one of our authorized service center undertaking replacement of the grease.

6.Service and repairs

All quality power tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only authorized replacement parts will be used, all service and repairs must be performed by a HITACHI AU-

THORIZED SERVICE CENTER, ONLY.
