MAINTENANCE AND INSPECTION

WARNING:
1. Inspecting the saw blade
Always replace the saw blade immediately upon the fi rst sign of deterioration or damage.
A damaged saw blade can cause personal injury and a worn saw blade can cause ineff ective
operation and possible overload to the motor.
CAUTION:
2. Inspecting the carbon brushes (Fig. 28 and Fig. 29)
The carbon brushes in the motor are expendable parts.
If the carbon brushes become excessively worn, motor trouble might occur.
Therefore, inspect the carbon brushes periodically and replace them when they have
become worn to the wear limit line as shown in Fig. 28.
Also, keep the carbon brushes clean so that they will slide smoothly within the brush
holders.
Use a slotted screwdriver to turn the spring-loaded cap counterclockwise carefully to
remove the cap on the side of the motor. Pull out the carbon brush and replace. The ears on
the metal end of the assembly go in the same hole the carbon part fi ts into. Last, tighten the
cap snugly, but do not overtighten. Repeat above procedure for the carbon brush located
on the other side of the motor.
NOTE:
When replacing the carbon brushes, use only metabo HPT carbon brushes.

To avoid an accident or personal injury, always confi rm that
the trigger switch is turned OFF and the power plug has been
disconnected from the receptacle before performing any
maintenance or inspection of this tool.
Never use a dull saw blade. When a saw blade is dull, its resistance
to the hand pressure applied by the tool handle tends to increase,
making it unsafe to operate the power tool.
Using this saw with a carbon brush which is worn in excess of the
wear limit will damage the motor.
