General Power Tool Safety Warnings


WARNING: Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool. Failure to follow all
instructions listed below may result in electric shock,
fire and/or serious injury.

SAVE ALL WARNINGS AND
INSTRUCTIONS
FOR FUTURE REFERENCE
The term ‚power tool‚ in the warnings refers to your mains-operated (corded) power tool.

General Safety Instructions
1 . KEEP GUARDS IN PLACE and in working order.
2 . REMOVE ADJUSTING KEYS AND WRENCHES. Form
habit of checking to see that keys and adjusting wrenches
are removed from tool before turning it on.
3 . KEEP WORK AREA CLEAN. Cluttered areas and benches
invite injuries.
4 . DON’T USE IN DANGEROUS ENVIRONMENT. Don’t
use power tools in damp or wet locations, or expose them
to rain. Keep work area well lighted. Always operate tool
in a well-ventilated area free of combustible materials,
gasoline or solvent vapors. If sparks come in contact

or explosion.
5 . KEEP CHILDREN AWAY. All visitors should be kept safe
distance from work area.
6 . MAKE WORKSHOP KID PROOF with padlocks, master
switches, or by removing starter keys.
7 . DON’T FORCE TOOL. It will do the job better and safer at
the rate for which it was designed.
8 . USE RIGHT TOOL. Don’t force tool or attachment to do a
job for which it was not designed.
9 . USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry
the current your product will draw. An undersized cord
will cause a drop in line voltage resulting in overheating
and loss of power. The Minimum Gauge for Cord Sets
table shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use the
next heavier gauge. The smaller the gauge number, the
heavier the cord. When operating a power tool outside,
use an outdoor extension cord marked “W-A” or “W.”
These cords are rated for outdoor use and reduce the risk
of electric shock.
10 . WEAR PROPER APPAREL. Do not wear loose clothing,
gloves, neckties, rings, bracelets, or other jewelry which
may get caught in moving parts. Nonslip footwear is
recommended. Wear protective hair covering to contain
long hair. Air vents often cover moving parts and should
also be avoided.
11 . ALWAYS USE SAFETY GLASSES. Also use face or
dust mask if cutting operation is dusty. Everyday
eyeglasses only have impact resistant lenses, they are not
safety glasses.

this tool.

Fan-Assisted Chip Ejection System
Your planer is equipped with a fan-assisted chip ejection
system to aid in exhausting chips from the unit. The fanassisted chip ejection system will work in conjunction with
independent dust collection systems.
NOTE: It is not recommended that a shop vac be
connected to the DW735. The capacity of most vacs does
not support the volume of chips ejected during planing.
The vacuum hose may clog stopping the flow of chips. It is
recommended to use the dust collection system to clean
debris from the interior of the tool.
See the Troubleshooting Guide, for additional information.

Automatic Carriage Lock
There is no manual carriage lock on your planer. A

1. Be sure the carriage is set above 1–1/4" (32 mm) before
trying to set the turret stop.
2. Turn the dial on the front left of the planer until the
desired thickness setting aligns with the red indicator,
then lower the carriage.
3. Plane the workpiece at desired increments until the
correct final thickness is achieved.
NOTE: Do not use force to crank the carriage below
the level that the turret stop indicates. Permanent
damage to the height adjustment system on your
planer will result.

OPERATION



WARNING: To reduce the risk of serious personal

12

To remove material thickness more quickly, set the unit
at speed “2”. This setting delivers 96 cuts per inch to
the material.
For finishing, set the unit to speed “1”. Speed “1” is ideal for
ensuring the finest finish on the last pass before your final
thickness is achieved.
NOTE: When planing particularly hard or figured species of
wood, speed “1” is recommended. The slower feed rate will
reduce knife wear and tear-out by delivering 179 cuts per
inch to the material.

Material Removal Gauge (Fig. K)
Your planer is equipped with a material removal
gauge 15 . It is used to indicate the amount of wood that
will be removed in one pass with the carriage set at its
current height.
Fig. K

15

To Use the Material Removal Gauge
1. Slide approximately 3" (75 mm) of your material under
the middle of the carriage.
2. Be sure the wood is lying flat against the base of the
planer. If the material is inserted at an angle, the reading
may be inaccurate.
3. Crank the carriage down on the material until the
material removal bar engages the wood. You will see
the red arrow begin to move up the scale indicating the
amount of material to be removed with the carriage at
that height.
4. Adjust the carriage height until the desired depth of cut
appears on the gauge.
5. Pull the material out from under the carriage.
6. Turn the unit on and feed your material into
the cutterhead.
NOTE: Do not exceed the recommended depth of cut for
various widths of material recommended on the material
removal gauge.
7

English



WARNING: DO NOT switch the unit on with the
material positioned under the carriage. Serious
injury could result.

Planing Basics
Proper Planing Technique



WARNING: DO NOT turn the unit on with the
material already inserted under the carriage.
Wait until the rollers and cutterhead are up to
full speed before feeding your material into
the machine.

To Plane Your Material
1. Lower the carriage to the desired height for your
first pass.
2. Turn the unit on and feed the material into the
feed rollers.
3. Examine the finished cut and adjust the carriage to the
appropriate height for your next pass.
NOTE: Flip the board back and forth between each pass.
See the Troubleshooting Guide, for additional information.
For best results, plane both sides of the workpiece to reach
a desired thickness. For example, if you need to remove 1/8"
(3 mm) from your workpiece, remove 1/16" (1.6 mm) from
each side. This not only allows the workpiece to dry with an
even moisture content, it also produces finer cuts.
WARNING: Plane only wood that is free from foreign
objects, with no loose knots and as few tight knots as
possible. Do not plane wood that is severely warped,
twisted, knotted or bowed.
WARNING: Do not place your body between the rear
of the planer and a stationary object while material is
feeding. Serious injury could result.




Minimum/Maximum Width/
Height/ Depth
NOTE: Always plane in the direction of the grain. Support
the workpiece adequately at all times. Planing material less
than 3/4" (19 mm) wide is not recommended. If you must
plane narrow material, group several pieces together and
plane them as one wide workpiece whenever possible.
The maximum depth of cut your planer can take in one pass
is 1/8" (3 mm) [on material less than 6" (152 mm) wide].
Never attempt to modify your planer to take a deeper cut.
Follow the recommended depth/width of cut guidelines
shown in Table A for best results.

TABLE A

Snipe
Snipe is a depression made when an unsupported end of
your material drops toward the floor, causing the opposite
end to lift up into the cutterhead.

To Avoid Snipe
Feed the workpiece into the planer so it is level and remains
flat against the base at all times.
Keep the workpiece level throughout planing operation by
receiving or ‚catching‚ it from the rear of the planer.
If you are planing material that is especially long, the use of
additional material support is recommended.

Twisted, Cupped and Bowed Wood (Fig. L)
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.
Fig. L

To Plane Twisted Wood (Fig. M)



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.
Fig. M

To Plane Cupped Wood (Fig. N)
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.

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.
