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 commutator surface will “wear” longer.

BEARINGS

Model 398-49 has ball bearing construction. Under normal use no additional lubrication is required.

Cleaning

!WARNING To avoid accidents always disconnect the tool from the

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

Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings.

!CAUTION Certain cleaning agents and solvents damage plastic parts.

Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

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.
