MAINTENANCE AND INSPECTION

WARNING:
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:
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.
NOTE: Use metabo HPT 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 metabo HPT AUTHORIZED SERVICE
CENTER, ONLY.
Be sure to switch power OFF and disconnect the plug from the receptacle
during maintenance and inspection.
Using this demolition hammer with loosen screws is extremely
dangerous.
