4. Inspecting the carbon brushes (Fig. 21)
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.
5. Replacing the carbon brushes
(1) Loosen the screws (2) for the chuck cover, then
remove the chuck cover from the housing (Fig. 17,
Fig. 18).
(2) Pinch the terminals for the carbon brushes with
pliers, then pull them out of the brush holder (Fig.
19).
(3) Pull the springs forward with a Phillips screwdriver,
then remove the carbon brushes (Fig. 20).
(4) Reverse these procedures to install the brushes.
6. Cleaning on the outside
When the power tool is stained, wipe with a soft
dry cloth or a cloth moistened with soapy water.
Do not use chloric solvents, gasoline or paint thinner,
as they melt plastics.
7. Storage
Store the power tool in a place in which the
temperature is less than 40°C and out of reach of
