Maintenance ol
Tool
Cleaning
Blowing dust and
grit
out oI the
motor housing using compressed
air is
a
necessary regular maintenance
procedure.
Dust and
grit
containing
metal
particles
often accumulate on
interior surfaces and
could create
an electrical shock hazard
if not frequently
cleaned
out.
CAUTION:
Never use solvenls or other
harsh
chemicals
for
cleaning
the
non-metallic
parts
of
the tool.
Use
clean, dry rag only.
Lubrication
DeWALT tools are
properly
lubricated at the
factory
and
are
ready for
use.
Tools should be
relubricated regularly every sixÿ days
to six
months,
depending on
usage.
(Tools
used constantly
on
production
or
heavy-duÿ
iobs
and
tools exposed to
heat may require more
frequent
lubrication.) This lubrication should only be attempted
by trained
power
tool repairpersons.
