KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
CONSIDER WORK AREA ENVIRONMENT. Don't use power tools in damp
or wet locations. Keep work area well
lit. Don't expose power tools to rain.
Don't use tool in presence of flammable liquids or gases.
KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don't let visitors contact tool or extension cord.
STORE IDLETOOLS. Whennot
in use, tools should be stored indry, and high
or locked-up place
- out of reach of children.
DON'T FORCE TOOL.
It will do thejob better andsafer at the rate for which
it was intended.
USE RIGHT TOOL. Don't force smalf tool or attachment to do the job of a
heavy-duty tool. Don't use tool for purpose not intended.
DRESS PROPERLY. Don't wear loose clothing orjewelry. They can becaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering to contain long hair.
USE SAFETY GLASSES. Also use face or dust mask
if cutting operation is
dusty.
DON'T ABUSE CORD. Never carry tool by cord or yank
it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold work. It's safer than using
your hand and
it frees both hands to operate tool.
DON'T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing acces-
sories. Inspect toolcords periodicallyand if damaged, haverepairedby autho-
rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECTTOOLS. When not inuse, before servicing, and when chang-
ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removed fromtool beforeturning
it on.
15. AVOID UNINTENTIONAL STARTING. Don‘t carry plugged-intool with finger
on switch. Be sure switch is
OFF when plugging in.
16. OUTDOOR USE EXTENSION CORDS. When tool is usedoutdoors, use only
extension cords intended for use outdoors and
so marked.
17. STAY ALERT. Watch what you are doing, use common sense. Don’t operate
tool when you are tired.
18. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other
part that is damaged should be carefully checked to determine that
it will
operate properly and perform its intended function. Check for alignment of
movingparts, bindingof movingparts, breakage of parts, mounting, andany
other conditions that may affect its operation. A guard or other part that
is damaged should be properly repaired or replaced by an authorized serv-
ice center unless otherwise indicated elsewhere inthis instruction manual.
Have defective switches replaced by authorized service center. Don’t use
tool if switch does not turn
it on and off.
19. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
20. REPLACEMENTPARTS.When servicing, use only identical replacement parts.
VOLTAGE WARNIN?: Beforeconnecting the tool toa power source (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplateof the tool. A power source with voltage greater than that specified
for the tool can result
in SERIOUS INJURY to the user - as well as damage to
the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source
with
voltage less than the nameplate rating is harmful to the motor.

ADDITIONAL SAFETY RULES
1. Rags, cloth, cord, string and the like should never be left around the work
2. Avoid cuttingnails. Inspectfor and remove all nails from the workpiece be-
3. Handle the blades very carefully.
4. Be sure the blade installation bolts are securely tightened before operation.
5. Hold the tool firmly with both hands.
6. Keep hands away from rotating parts.
7. Before using the tool on an actual workpiece, let it run for a while. Watch
for vibration or wobbling that could indicate poor installation or a poorly
balanced blade.
8. Make sure the blade is not contacting the workpiece before the switch is
turned on.
9. Wait until the blade attains full speed before cutting.

Removing or installing planer blades
CAUTION :
Always be sure that the tool is switched off and unplugged before removingor installing
the blade.
The blade
is secured with four bolts. Re-
move the inner two bolts entirely with
the socket wrench and loosen the outer
two bolts two turns each.
Press down on the pin inthe middle of the
drum with one end of the socket wrench
handle. The blade can be pushed and
jiggled out
so as to be removed. (If the
blade becomes
so short that it cannot be
grasped,
you must remove the four bolts
and the drum cover. Then push the blade
out with one end
of the socket wrench
handle.)
To install the blades, first clean out all
chips or foreign matter adhering to the
drum or blades. Use blades of the same
dimensions and weight, or drum oscilla-
tionhibration will result, causing poor
planing action and, eventually, tool break-
down.
Insert the blade, holding both ends,
so that
it protrudes from between the blade holder
and the drum. Then secure the four bolts
only finger-tight.

Align the blade edge with the mark and
make the drum stationary by means of the
stopper pin.
Place the leveller over the rear
base and blade, and press the leveller down
slightly.
Release the stopper pin.
Turn the drum in the direction of the
arrow
(Fig. 6) to check the blade protru-
sion, holding the leveller flush against the
blade and rear base. The blade edge should
just contact the underside of the leveller.
When the blade edge does not protrudefar
enough from the base, press down on the
pin in the middle of the drum with the
socket wrench handle, and adjust the
blades again
as mentioned above. After
adjusting both blades, tighten the four in-
stallation bolts evenly and alternately with
the socket wrench.

loose installationbolt can be dangerous. Always check to see they are tightened securely.

For the correct planer bladesetting
Your planing surface
will end up rough and uneven, unless the blade is set properly and
securely. The blade must
be mounted so that the cuttingedge is absolutely level, that is,
parallel to the surface
of the rear base. Below are some examples of proper and improper
settings.

(B)Rear base (Stationaryshoe)
Although this side view cannot show
it, the edges of the blades run perfectlv
parallel to the rear base surface.

Adjusting depth of cut
Depth of cut may
be adjusted by simply
turning the knobon
the front of the tool.
Switch action
To start the tool, simply pull the trigger.
Release the trigger tostop. For continuous
operation, pull the trigger and then push in
the lock button.
To stop the tool from the
locked position. pull the trigger fully, then
release
it.

CAUTION :
Before plugging in the tool, always check to see that the trigger switch actuates properly
and returns tothe
"OFF" position when released.

Planingoperation
First, rest the tool front base flat upon the
workpiece surface without the blades mak-
ing any contact. Switch on and wait until
the blades attain full speed. Then move the
tool gently forward. Apply pressure on the
front of tool
at the start of planing, and at
the back at the end of planing. Planingwill
be easier if you incline the workpiece in
stationary fashion,
so that you can plane

somewhat downhill. The speed and depth
of cut determine the kind of finish. The power planer keeps cutting
at a speed that will
not result injamming bychips. Forrough cutting, the depth of cut can be increased, while
for
a good finish you should reduce the depth of cut and advance the tool more slowly.
Chamfering
To make
a cut as shown at the right, align the "V" groove inthe
front base with the edge of the workpiece and plane
it as shown
inthe figure (A).
Sharpening planer

Always keep your blades sharpfor the best
performance possible.
Use the sharpening

to remove nicks and produce a fine
edge.

First, loosen the two wing nuts on the
holder and insert the blades
(A) and (B)
so that they contact the sides (C) and (D).
Then tighten the wing nuts.
Immerse the dressing stone in water for
2
or 3 minutes before sharpening. Hold the
holder
so that the blades both contact the
dressing stone for simultaneous sharpening
at the same angle.

MAINTENANCE
CAUTION :
Always be sure that the tool is switched off and unpluggedbefore attempting to perform
inspection
or maintenance.
The tool will stop when the carbon brushes wear to
a certain length. When this occurs,
both carbon brushes should be replaced.
To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection and
replacement, any other maintenance or adjustment should be performed by Makita
Authorized or Factory Service Centers, always using Makita replacement parts.
