MAINTENANCE

Your D WALT power tool has been designed to operate over a
E
long period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and regular
cleaning.
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments
or accessories. Before reconnecting the tool, depress and
release the trigger switch to ensure that the tool is off.
Cleaning
WARNING: Blow dirt and dust out of the main housing with dry air
as often as dirt is seen collecting in and around the air vents. Wear
approved eye protection and approved dust mask when performing
this procedure.
WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
weaken the materials used in these parts. Use a cloth dampened
only with water and mild soap. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.

Lubrication

D WALT tools are properly lubricated at the factory and are ready
E
for use. Tools should be relubricated regularly every sixty days to six
months, depending on usage. (Tools used constantly on production
or heavy-duty jobs and tools exposed to heat may require more
frequent lubrication.) This lubrication should only be attempted by
trained power tool repair persons such as those at D
centers or other authorized service locations.
Motor Brushes (Fig. 1)
Be sure tool is unplugged before inspecting brushes. Carbon brushes
should be regularly inspected for wear. To inspect brushes, unscrew
the plastic brush inspection caps (located in the sides of the motor
housing) and the spring and brush assemblies may be withdrawn
from the tool. Keep brushes clean and sliding freely in their guides.
Carbon brushes have varying symbols stamped into them, and if the
brushes are worn down to the line closest to the spring, they must
be replaced.

Accessories

WARNING: Since accessories, other than those offered by
D WALT, have not been tested with this product, use of such
E
accessories with this tool could be hazardous. To reduce the risk of
injury, only D WALT recommended accessories should be used with
E
this product.
Recommended accessories for use with your tool are available at extra
cost from your local dealer or authorized service center.
Use only accessories having a maximum operating speed at least as

This precaution applies to any accessory on any tool.
