MAINTENANCE AND INSPECTION

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

1.Inspecting the tool

Since use of a dull tool will degrade efficiency and cause possible motor malfunction, sharpen or replace the tool as soon as abrasion is noted.

2.Inspecting the mounting screws

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

WARNING: Using this demolition hammer with loosen screws is extremely dangerous.

3.Inspecting the carbon brushes (Fig. 7)

The Motor employs carbon brushes which are consumable parts. When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

Fig. 7

NOTE: Use HITACHI carbon brush No. 86 indicated in Fig. 7.

4.Replacing carbon brushes (Refer to figure for name of parts)

Loosen the screws (Hexagon socket hd. bolt M4 ⋅ 12) of the cap covers, then remove the cap covers. After removing the brush caps, the carbon brushes can be removed.

After replacing the carbon brushes, tighten the brush caps, then mount the cap covers securely.

5.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 AUTHORIZED SERVICE CENTER, ONLY.
