DeWalt DW368 Manual De Instrucciones página 10

E. Backing unit up to clear blade can lead to twist if not done
carefully.
4. MATERIALS THAT REQUIRE EXTRA ATTENTION
A. Wet lumber
B. Green lumber (material freshly cut or not kiln dried)
C. Pressure treated lumber (material treated with preservatives or
anti-rot chemicals)
5. USE OF DULL OR DIRTY BLADES
Dull blades cause increased loading of the saw. To compensate,
an operator will usually push harder which further loads the unit
and promotes twisting of the blade in the kerf. Worn blades may
also have insufficient body clearance which increases the chance
of binding and increased loading.
6. LIFTING THE SAW WHEN MAKING BEVEL CUTS
Bevel cuts require special operator attention to proper cutting
techniques - especially guidance of the saw. Both blade angle to
the shoe and greater blade surface in the material increase the
chance for binding and misalignment (twist) to occur.
7. RESTARTING A CUT WITH THE BLADE TEETH JAMMED
AGAINST THE MATERIAL
The saw should be brought up to full operating speed before
starting a cut or restarting a cut after the unit has been stopped
with the blade in the kerf. Failure to do so can cause stalling and
kickback.
Any other conditions which could result in pinching, binding, twisting,
or misalignment of the blade could cause kickback. Refer to the
sections on "Adjustments And Set-Up" and "Operation" for procedures
and techniques that will minimize the occurrence of kickback.
MAINTENANCE
Cleaning and Lubrication
Use only mild soap and a damp cloth to clean the tool. Many
household cleaners contain chemicals which could seriously damage
plastic. Also, do not use gasoline, turpentine, lacquer or paint thinner,
dry cleaning fluids or similar products. Never let any liquid get inside
the tool; never immerse any part of the tool into a liquid.
Self lubricating ball and roller bearings are used in the tool and
relubrication is not required. However, it is recommended that, once
a year, you take or send the tool to a service center for a thorough
cleaning, inspection and lubrication of the gear case.
Brushes
DISCONNECT PLUG FROM POWER SUPPLY BEFORE SERVICING
Inspect carbon brushes regularly by unplugging tool, removing the
End Cap (Detail Page 4) 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 either brush is worn down to the line closest to the spring, they
must be replaced. Use only identical D
assemblies are available at your local service center. The tool should
be allowed to "run in" (run at no load without a blade) for 5 minutes
before use to seat new brushes.
While "running in" DO NOT TIE, TAPE, OR OTHERWISE LOCK THE
TRIGGER SWITCH ON. HOLD BY HAND ONLY.
SHOE ADJUSTMENT
DISCONNECT PLUG FROM POWER SUPPLY.
Your shoe has been factory set to assure that the blade is perpen-
dicular to the shoe. If after extended use, you need to re-align the
blade as follows:
ADJUSTING FOR 90 DEGREE CUTS
1. Return the saw to 0 degrees bevel.
2. Place the saw on its side, and retract the
lower guard.
3. Loosen the Bevel Adjustment Lever
(Figure 7 (A). Place a square against the
blade and the shoe.
