MAINTENANCE AND INSPECTION

WARNING:
1. Inspecting the cutter
Continued use of a dull or damaged cutter will result in reduced cutting efficiency and
may cause overloading of the motor. Replace the cutter with a new one as soon as
excessive 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. Maintenance of the motor
The motor unit winding is the very "heart" of the power tool. Exercise due care to
ensure the winding does noto become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig. 24)
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. 43 indicated in Fig. 24.

5. Replacing carbon brushes

Loosen the set screws and remove the tail cover. Remove the brush caps and carbon
brushes. After replacing the carbon brushes, do not forget to tighten the brush caps
securely and to mount the tail cover with set screws.

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 metabo HPT AUTHORIZED
SERVICE CENTER, ONLY.
