MAINTENANCE
INSTALLING A NEW BELT
NOTE:
No tools are necessary to install a belt. The use of a screwdriver
or other tool to pry or stretch a belt may cause damage to the pulleys
and ultimately destroy the new belt.
WARNING:
TURN OFF THE PLANER AND DISCONNECT IT FROM
THE POWER SOURCE.
1. Remove the crank handle.
2. Remove the two Allen screws from the top, right side of the
planer.
3. Remove the two, small Phillips head screws securing the side
panels to the top of the planer.
4. Lift the side panel up out of the slot in the base and remove
the panel fro the machine. Notice the grooves inside the belt.
5. Start the belt on the top pulley (P) with 3 grooves on the pulley,
as shown in Figure 22.
6. Guide the belt between the lower pulley and the height adjust-
ment screw (Q), as shown in Figure 23.
7. With three grooves engaged on the large pulley, rotate the pul-
ley clockwise. Keep pressure on the edge of the belt to keep
the grooves engaged on the small pulley.
8. Continue pressure on the side of the belt and rotate the large
pulley while hopping the belt further onto the pulleys, as shown
in Figure 24.
9. All of the belt grooves should be engaged in the final position
and the pulleys should rotate smoothly.
10. Reinstall the side cover and the screws. Do not overtighten the
self-tapping screws.
CALIBRATING THE DEPTH ADJUSTMENT SCALE
The depth adjustment scale on your planer is set at the factory.
However, with extended use, the depth adjustment scale could show
an incorrect measurement.
TO CHECK THE DEPTH ADJUSTMENT SCALE
1. Plane a piece of wood, noting the measurement on the depth
adjustment scale.
2. Measure the finished thickness of the workpiece.
3. If the thickness of the workpiece does not match the reading
on the depth adjustment scale, loosen the two Phillips head
screws (R) shown in Figure 25.
4. Adjust the pointer up or down until its reading matches the
finished thickness of the workpiece. Securely re-tighten the
screws.
LEVELING THE TABLE EXTENSIONS
After extended use, the table extensions might become slightly out of
level. To ensure that the tables are level, place a straight edge on the
table extension. The straight edge should contact the edge of the table
extension and the main table (Fig. 7). When leveling, press the edge of
the table extensions down to remove any play. For best results, use a
level long enough to contact the edges of both table extensions.
If the table extensions are not level, loosen the jam nuts (T) and adjust
the table extension support bolts (S) up or down (Fig. 26).
NOTE:
The outside edges of the extension tables are level with the base
while the inside edges (closest to the cutter head) are below the edge
of the base. This is set at the factory to reduce unnecessary friction
between the material and the table while providing adequate support at
the two points (those farthest from the cutter head) on the tables that
are integral to snipe prevention.
TABLE
Keep the table clean and free from oil, grease and pitch. Treat the
table with paste wax to help maintain its smooth finish.
CIRCUIT BREAKER RESET BUTTON
Your planer is equipped with an 18 amp circuit breaker. If your planer
becomes overloaded and stops operating, turn off the planer, let the
unit sit for 2 minutes and press the reset button (U) (Fig 27) before
you resume working.
WARNING:
To prevent the planer from starting unexpectedly if
power is interrupted by a circuit breaker trip, make sure the switch is in
the OFF position before restoring power.
NOTE:
Circuit breaker overload is often the result of dull knives.
Change your knives on a regular basis to avoid tripping your breaker.
Check your knives before re-setting the circuit breaker and continuing
to plane.
See the Troubleshooting Guide at the end of this section for more
information.
BRUSHES
Inspect carbon brushes regularly. Keep brushes clean and sliding
freely in their guides. Always replace a used brush in the same orien-
tation in the holder as it was prior to its 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 identical D
E
WALT brushes.
New brush assemblies are available at D
E
WALT service centers. After
replacing brush assemblies, the tool should be allowed to “run in” (run
at no load) for 10 minutes to seat new brushes before using.
TO REMOVE BRUSH ASSEMBLY
WARNING:
DISCONNECT TOOL FROM THE POWER SOURCE
BEFORE ATTEMPTING TO REMOVE BRUSH ASSEMBLY.
1. Remove the brush inspection cap (V) (Fig 28).
2. Withdraw the brush assembly.
CLEANING AND LUBRICATION
CAUTION:
Never let any liquid get inside the tool; never immerse
any part of the tool into a liquid. Electric shock may result.
CAUTION:
Never use solvents or other harsh chemicals for cleaning
the non-metallic parts of the tool.
It is recommended that, once a year, you take or send the tool to a
D
E
WALT certified service center for a thorough cleaning, inspection
and lubrication of the gear case.
