CARBON BRUSHES

When the carbon brushes are worn down, the Auto-Stop feature will
automatically turn the machine off in order not to damage the motor.
The brushes must then be replaced. Use only genuine WALTER carbon
brushes. These brushes are specially made for this tool; they will maintain
its high performance standard and ensure maximum life of the motor.
To check or replace carbon brushes:
1. Disconnect the tool from power supply.
2. Remove motor housing cover.
3. Carbon brushes may be pulled from their holders after lifting spring and
detaching the connector.
4. Replace brushes if necessary. Always replace them in pairs.
5. Check that the new brushes move freely in their holders. To help seat the
carbon brushes properly after they have been installed, use the power
tool without applying a heavy load for at least 30 minutes.
However, when the carbon brushes require replacement, it is recommended
that the tool be sent to a WALTER Factory Service Center or a WALTER
Authorized Service Center. Apart from changing the brushes, your power
tool will be cleaned, inspected and lubricated as required. If new parts are
necessary, only genuine WALTER replacement parts will be used.

PREVENTIVE MAINTENANCE

Your WALTER power tool should be properly maintained to insure
continued high performance. Use low pressure compressed air to blow
out dust from the motor through the vent openings. Clean dust and dirt
deposits from the exterior of the tool. Clean the power cord to prevent
deterioration from oil and grease and check for possible damage.
Note: Damaged cord sets must be replaced. Refer
to Spare Parts List for the ordering number.
