MAINTENANCE AND INSPECTION

WARNING:
1. Inspecting the diamond wheel
Since use of a dull diamond wheel will cause motor malfunctioning and degraded
efficiently, replace with a new one without delay when abrasion is noted.
2. Inspecting the screws
Regularly inspect all screws and ensure that they are fully 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 not become
damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig. 6)
The motor employs carbon brushes which
are consumable parts. Replace the carbon
brush with a new one when it becomes
worn to its wear limit. Always keep carbon
brushes clean and ensure that they slide
freely within the brush holders.
CAUTION
●
Using this grinder with a carbon brush which is worn in excess of the wear limit will
damage the motor.
NOTE: Use metabo HPT carbon brush No. 43 indicated in Fig. 6.
Replacing carbon brushes:
Loosen the set screw 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 install the tail cover.
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.
