MAINTENANCE AND INSPECTION

WARNING
Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and
inspection.
Using cracked, deformed or damaged wheels can lead to wheel breakage and resulting serious injury.
1. Inspecting the cutting wheel
Ensure that the cutting wheel is free of cracks and
surface defects.
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
Using this cut-off machine with loosened screws
is extremely dangerous.
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. 4)
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 number indicated in

5. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
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.
