minutes before loading (or using) the tool. This will allow the brushes to “seat” properly and will give you more hours of life from each set of brushes. This will also extend the total life of your tool since the com- mutator surface will “wear” longer.

BEARINGS

Model 398 has ball bearing construction. Under normal use no additional lubrication is required.

Cleaning

!To avoid accidents always dis- CAUTION connect the tool from the power

supply before cleaning or performing any main- tenance. The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air.

Extension Cords

!If an extension cord is WARNING necessary, a cord with adequate

size conductors that is capable of carrying the current necessary for your tool must be used. This will prevent excessive voltage drop, loss of power or overheating. Grounded tools must use 3-wire extension cords that have 3-prong plugs and receptacles.
