Width of stock (mm)
1. Slowly feed the workpiece into the machine.
2. Feed the workpiece in the direction of the grain.

Snipe

Snipe is a depression made when the ends of the workpiece contact
the cutters. To avoid snipe:
1. Keep the workpiece level throughout the planing operation.
2. Feed the workpiece flat against the table.
Warping (fi g. P1–P4)
If your workpiece is only slightly warped, plane both sides to produce
the desired thickness.
BOWED WORKPIECES (FIG. P1, P2)
The feed rollers and cutterhead will temporarily flatten the workpiece
(fig. P1). The bowed shape, however, will return after planing (fig.P2).
• To remove the bow, use a jointer.
CUPPED WORKPIECES (FIG. P3, P4)
1. Rip the cupped workpiece in the middle (fig. P3).
2. Plane the pieces separately to eliminate waste.
• Alternatively, plane the top flat (55) first, turn the workpiece over
and plane the bottom flat (56) (fig. P4).
Dust Extraction (fi g. A1)
The machine is provided with a 100 mm dust extraction port on the
guard/chip collector (4). Provided with a suitable dust extraction device,
90% of the produced shaving can be caught if the air flow is at least
20 m/s.
Connect a suitable dust extraction device during all operations.
Whenever possible, connect a dust extraction device designed in
accordance with the relevant regulations regarding dust emission.
Transporting (fi g. Q1, Q2)
The castor wheels (30) provide an easy transport of the machine.
Securely holding the handle with both hands, transport the machine as
shown in figure Q2.

MAINTENANCE

Your D WALT power tool has been designed to operate over a long
E
period of time with a minimum of maintenance. Continuous satisfactory
operation depends upon proper tool care and regular cleaning. Every
week inspect Anti-kickback device and feet spindles for good working
order to ensure safe operation.
WARNING: To reduce the risk of injury, turn unit off
and disconnect machine from power source before
installing and removing accessories, before adjusting
or changing set-ups or when making repairs. Be sure
the trigger switch is in the OFF position. An accidental start-
up can cause injury.
Replacing the Blades (fi g. R1, R2)
The machine is equipped with a cutterhead that holds two blades.
WARNING: Always replace the blades simultaneously.

WARNING! Be aware the cutting blades shall be replaced
in the described way only. Never fit cutting blades other
than the ones recommended.
WARNING: Sharp edges.
WARNING: Wear gloves when replacing the blades.
WARNING: Prior to replacing the blades always unplug the
machine.
Removing the Blades
1. Remove the fence and the guard.
2. Carefully rotate the cutterhead (57) until the first blade becomes
visible.
3. Loosen the bolts (58) using the spanner supplied.
4. Lift the blade assembly (59) out of the cutterhead. Use a pair of
pliers if necessary.
5. Take the blade (60) from the holder (61).
6. Repeat as for the other blade.
Fitting the Blades
1. Attach the blade (60) to the blade holder (61). Make sure that the
outer bolt heads (62) fall in notches (63).
2. Re-fit the assembly into the cutterhead (57).
3. Adjust the blade as described below.
4. Tighten the bolts (58) (torque: 6-8 Nm).
5. Repeat as for the other blade.
Adjusting the Blades (fi g. R3)
1. Check the position of the blade (60) at both ends.
2. Position the gauge (64) over the cutterhead (57) as shown.
3. The bottom edge of the gauge must coincide with the tip of the
blade (60).
• If adjustment is required, proceed as follows:
• Turn each adjusting screw (65) in or out as necessary until the
blade tip coincides with the gauge.
Re-sharpening the Blades
The blades can be re-sharpened at 42°.
WARNING: The blades can be re-sharpened max. 3
mm down from their original size. If the blade size has
decreased by more than 3 mm, the blades have to be
replaced.
Lubrication
Your power tool requires no additional lubrication.
Cleaning
WARNING: Blow dirt and dust out of the main housing
with dry air as often as dirt is seen collecting in and around
the air vents. Wear approved eye protection and approved
dust mask when performing this procedure.
WARNING: Never use solvents or other harsh chemicals
for cleaning the non-metallic parts of the tool. These
chemicals may weaken the materials used in these parts.
Use a cloth dampened only with water and mild soap.
Never let any liquid get inside the tool; never immerse any
part of the tool into a liquid.
Before use, carefully check the cutter-head to determine that it will
operate properly. Ensure that resin or workpiece particles cannot lead to
blockage of one of the functions.
