DeWalt DW735 - Periodic Maintenance

11
ENGLISH
Periodic Maintenance
1. Routinely check the tool for damage or brokenparts.
2. Clean the top cover, dust shroud and all accessible areas
of the unit of dust and wood debris that have collected in
fromplaneing.
MAINTENANCE
Your 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.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can causeinjury.
3. Wipe off infeed and outfeedrollers.
4. Clean base table. Light waxing will help wood material pass
through theplaner.
5. Evaluate blade sharpness condition. Replace asnecessary.
6. Gauge Calibration, check thickness gauge calibration and
turret stopcalibration.
7. Check brushes for wear and replace asnecessary.
Changing or Rotating the Planer Knives

WARNING: To reduce the risk of serious personal
injury, disconnect the planer from the power source
before attempting to change or access the knives. An
accidental start-up can causeinjury.
To Change Planer Knives (Fig.N–S)
1. Use the T-wrench to remove the four screws in the top of
theplaner.
2. Lift the top off (Fig.N) and place itaside.
3. Remove the three wing nuts that seal the dust shroud over
thecutterhead.
4. Rotate the dust shroud up so the round connection that
locks onto the fan housing is in the open position (Fig.O).
5. Push the dust shroud to the left so it disengages from the
fanhousing.
6. Take the dust shroud out of the unit (Fig.P) and set itaside.
7. The cutterhead is nowexposed. If the eight screws in the
cutterhead clamp are not visible, use a piece of scrap wood
to carefully rotate the cutterhead (Fig.Q) until the screws
are accessible and the cutterhead lock lever
18
engages.
This will prevent further rotation of the cutterhead as you
change theknives.

WARNING: Keep your fingers away from the
cutterhead at all times. Use the tool provided to
handle theknives.
8. Use the T-wrench to remove the eight screws on the knife
clamp and set them in the small screws bin
19
on the front
panel of the planer (Fig.R).
9. Use the magnets on the top of the T-wrench to attract the
knife clamp and lift it off of the cutterhead. One of the knives
should now beexposed.
10. Use the magnet
20
on the top of the T-wrench (Fig.Q) to
attract the knife. Avoid touching it with yourfingers.
NOTE: Before installing the knife, ensure the cutterhead and
knife are free of debris, clean if needed.
If Only One Side of the Knife Is Worn
1. Rotate the knife around so that the sharp, unused edge
hangs over the end of the cutterhead where it will cut the
material. Be sure to set the oblong holes in the knife over
the pins machined on thecutterhead.
2. Reset the knife clamp over the knife. Be sure to align the
beveled edge on the clamp with the sharp, cutting edge of
the knife. If these are not aligned correctly, the clamp will
not secure the knifeproperly.
3. Install the screws into the clamp and tightensufficiently.
NOTE: Make sure all screws are tightenedsufficiently.
Twisted, Cupped and Bowed Wood (Fig. J)
If both sides of your material are very rough or if the material is
cupped, bowed or twisted, your planer may not produce the
desired result. Ideally, you should have at least one level face/
surface on your material before you plane. Your thickness planer
will work best with material that has been run through a jointer
to produce one flat surface. If you do not have at least one flat
surface or a jointer, see the followingrecommendations.
To Plane Twisted Wood (Fig.K)

WARNING: Twisted wood may jam your thickness
planer. If a jam occurs, turn the power off,
disconnect the power supply and raise the carriage
to release the material from thecutterhead.
If your material is only slightly twisted:
Plane both sides alternating from one to the other until the
desired thickness isreached.
To Plane Cupped Wood (Fig.L)
To obtain the best possible results with cupped wood:
Rip the material down the middle and plane it as two
separatepieces.
Ripping the material reduces the severity of the cup and allows
the machine to deliver better results. Understand that you will
have to remove more material on cupped wood to achieve the
desired thickness than you would on a normalboard.
If Ripping the Material is Not an Option
Plane one side of the material until flat, then plane the opposite
side until it is alsoflat.
NOTE: Do not flip the board back and forth between each pass
if wood iscupped.
To Plane Bowed Wood (Fig.M)
The feed rollers and cutterhead in your planer will push the bow
out of the material as it feeds. However, when the material exits
the planer, the pressure of the rollers and cutterhead will release
allowing the wood to spring back into a bowed formation. To
properly remove the bow, use ajointer. BOWED WOOD WILL
BE FLATTENED BY FEED ROLLERS AND CUTTERHEAD BUT BOW
WILL RETURN AFTER WOOD ISPLANED (Fig. M)
