MAINTENANCE
Your DEWALT power tool has been designed to
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
This machine is not user-serviceable. Take the
tool to an authorised DEWALT repair agent after
approximately 100 hours of use. If problems occur
before this time contact an authorised DEWALT
repair agent.

Grind the chisels on grinding discs. Refer to Figure 9
for the appropriate angles of the following chisels:
j. spade-shaped chisel
k. cold chisel
l. pointed chisel

WARNING: These chisels can be
reground only a limited number of
times. If in doubt, contact your dealer for
recommendations.
WARNING: Ensure that the cutting
edge does not show discolouration
caused by too much pressure. This may
impair the hardness of the accessory.
Lubrication
Your power tool requires no additional lubrication.
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
