Electric Brake - DeWalt D364-O4 Instruction Manual

10.
USE
ONLY BLADES
WITH 5/8"
DIAMETER
ARBOR.
Do not
ft
use blades with incorrect size holes. Never use defective or
'
incorrect blade washers
or
bolts.
11.
AVOID CUTTING
NAILS.
lnspect
for and remove
all
nails
from lumber before cutting.
CAUTION: When sawing into walls, floors or wherever "live"
electrical
wires may be encountered,
DO
NOT TOUCH ANY
METAL PARTS OF THE TOOL! Hold the Saw only by
its plas-
tic
handles
to prevent electric
shock
if you saw into a "live"
wire.
SAVE
THESE INSTRUCTIONS
Motor
Your DeWalt
tool is powered by
a
DeWalt-built motor. Be sure
your power supply
agrees
with nameplate marking. 120 Volts
AC/DC
means
your saw will operate on alternating or direct
cur-
rent.
Lower
voltage will cause loss
of power and can result
in
over-heating.
All
DeWalt
tools are factory-tested; if
this tool
does
not operate, check
the power supply.
Double lnsulation
Your unit is
DOUBLE INSUI-ATED.
This means
that it is
con-
structed
throughout with TWO
separate "layers" of electrical
insu-
lation
or one DOUBLE thickness
of
insulation between
you
and
the
tool's
electrical system.
Tools built with
this insulation system are not intended
to
be
grounded. As a result, your tool is equipped with a
two-prong plug
which permits
you to use
extension
cords without
concern for
maintaining a ground connection.
NOTE:
DOUBLE INSULATION does not take
the place of
normal
safeÿ precautions when operating
this
tool.
This
insulation sys-
tem is for added
protection againt injury
resulting
from a possible
,r{Bctrical
insulation failure within the tool.
-
l,UTION: When servicing
all tools, USE ONLY IDENTICAL
nEPIâCEMENT
PARTS. Repair
or replace damaged cords.
Electric Brake
Your saw has
an automatic electric brake
which is designed to
stop
the blade from coasting in about two seconds after you
release the trigger switch.
lt
is useful
when making certain
cuts
in
wood where
a
coasting blade would result
in a wide,
imprecise
cut.
Occasionally, under
certain conditions,
the
brake
will
not function
properly and
won't stop the saw in the 2 seconds
discussed
above.
lf this
condition persists, turn the
saw
on and off
four
or
five times.
lf
the brake still does not stop the blade in about 2 sec-
onds,
the
problem may
be
worn brushes. Replace the brushes as
described below and
try the
saw
again. lf the
problem still per-
sists, have the tool
seruiced at a service center or authorized ser-
vice
facility. DeWalt tools are serviced by
the lndustrial
Tool
Division
of
Black & Decker Canada lnc.
Brushes
DISCONNECT
PLUG
FROM POWER SUPPLY
lnspect
carbon brushes regularly by unplugging
tool,
removing
the'Brush
lnspection Cap
(Figure 2) and withdrawing
the
brush
assembly. Keep brushes clean and sliding freely in their
guides.
Always
replace
a used brush in
the
same orientation in
the holder
as it was
prior to
removal.
Carbon brushes have
varying symbols
stamped
into their sides, and if the
brushes are
worn
down
to the
line closest
to the
spring,
they must be replaced.
Use
only identi-
cal
DeWalt brushes.
Always replace both brushes. Use of the
correct grade of brush is
essential
for proper
operation
of electric
brakes. New brush assemblies
are available at
your
local service
center. The
tool should be allowed
to
"run
in" (run at no load with-
out blade)
for
10 minutes
before use
to seat
new brushes.
This
is
especially important
for saws equipped with electric
brakes,
which may be erratic
in
operation until
the
brushes
are properly
seated
(worn
in).
While "running in" DO
NOT
TlE, TAPE, OR OTHERWISE LOCK
THE TRIGGER SWITCH ON. HOLD BY HAND ONLY.
