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
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.
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
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.
