GENERAL SAFETY RULES GEA001-3
WARNING:
Read all instructions. Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury. The term “power tool” in all of the
warnings listed below refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
Work area safety
1. Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
2. Do not operate power tools in explosive atmos-
pheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while oper-
ating a power tool. Distractions can cause you to
lose control.
Electrical safety
4. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
5. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
6. Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the
risk of electric shock.
7. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords
increase the risk of electric shock.
8. When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of
electric shock.
Personal safety
9. Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
10. Use safety equipment. Always wear eye protec-
tion. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal inju-
ries.
11. Avoid accidental starting. Ensure the switch is
in the off-position before plugging in. Carrying
power tools with your finger on the switch or plug-
ging in power tools that have the switch on invites
accidents.
12. Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
13. Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected situations.
14. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
15. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
Power tool use and care
16. Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the rate
for which it was designed.
17. Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
18. Disconnect the plug from the power source and/
or the battery pack from the power tool before
making any adjustments, changing accessories,
or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool
accidentally.

4
19. Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
20. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tools operation. If damaged, have the power tool
repaired before use. Many accidents are caused
by poorly maintained power tools.
21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
22. Use the power tool, accessories and tool bits
etc. in accordance with these instructions and in
the manner intended for the particular type of
power tool, taking into account the working con-
ditions and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
23. Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
24. Follow instruction for lubricating and changing
accessories.
25. Keep handles dry, clean and free from oil and
grease.
GEB010-2
SPECIFIC SAFETY RULES
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to planer safety rules. If you use this tool unsafely or
incorrectly, you can suffer serious personal injury.
1. Wait for the cutter to stop before setting the
tool down. An exposed cutter may engage the sur-
face leading to possible loss of control and serious
injury.
2. Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand or against your body
leaves it unstable and may lead to loss of control.
3. Rags, cloth, cord, string and the like should
never be left around the work area.
4. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
5. Use only sharp blades. Handle the blades very
carefully.
6. Be sure the blade installation bolts are securely
tightened before operation.
7. Hold the tool firmly with both hands.
8. Keep hands away from rotating parts.
9. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or wob-
bling that could indicate poor installation or a
poorly balanced blade.
10. Make sure the blade is not contacting the work-
piece before the switch is turned on.
11. Wait until the blade attains full speed before
cutting.
12. Always switch off and wait for the blades to
come to a complete stop before any adjusting.
13. Never stick your finger into the chip chute.
Chute may jam when cutting damp wood. Clean
out chips with a stick.
14. Do not leave the tool running. Operate the tool
only when hand-held.
15. Always change both blades or covers on the
drum, otherwise the resulting imbalance will
cause vibration and shorten tool life.
16. Use only Makita blades specified in this man-
ual.
17. Always use the correct dust mask/respirator for
the material and application you are working
with.

ASSEMBLY CAUTION:
•Always be sure that the tool is switched off and unplugged before
carrying out any work on the tool.
Removing or installing planer blades
CAUTION:
•Tighten the blade installation bolts carefully when attaching the blades to
the tool. A loose installation bolt can be dangerous. Always check to see
they are tightened securely.
•Handle the blades very carefully. Use gloves or rags to protect your
fingers or hands when removing or installing the blades.
•Use only the Makita wrench provided to remove or install the blades.
Failure to do so may result in overtightening or insufficient tightening of
the installation bolts. This could cause an injury.
For tool with standard planer blades
To remove the blades on the drum, unscrew the installation bolts with the
socket wrench. The drum cover comes off together with the blades.
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 oscil-
lation/vibration will result, causing poor planing action and, eventually, tool
breakdown.
Place the blade on the gauge base so that the blade edge is perfectly flush
with the inside edge of the gauge plate. Place the adjusting plate on the blade,
then simply press in the heel of the adjusting plate flush with the back side of
the gauge base and tighten two screws on the adjusting plate. Now slip the
heel of the adjusting plate into the drum groove, then fit the drum cover on it.
Tighten all the installation bolts evenly and alternately with the socket wrench.

For tool with mini planer blades
1. Remove the existing blade, if the tool has been in use, carefully clean the
drum surfaces and the drum cover. To remove the blades on the drum,
unscrew the three installation bolts with the socket wrench. The drum
cover comes off together with the blades.
2. To install the blades, loosely attach the adjusting plate to the set plate
with the pan head screws and set the mini planer blade on the gauge
base so that the cutting edge of the blade is perfectly flush with the inside
flank of the gauge plate.
3. Set the adjusting plate/set plate on the gauge base so that the planer
blade locating lugs on the set plate rest in the mini planer blade groove,
then press in the heel of the adjusting plate flush with the back side of the
gauge base and tighten the pan head screws.
4. It is important that the blade sits flush with the inside flank of the gauge
plate, the planer blade locating lugs sit in the blade groove and the heel
of the adjusting plate is flush with the back side of the gauge base.
Check this alignment carefully to ensure uniform cutting.

5. Slip the heel of the adjusting plate into the groove of the drum.
6. Set the drum cover over the adjusting plate/set plate and screw in the
three hex flange head bolts so that a gap exists between the drum and
the set plate to slide the mini planer blade into position. The blade will be
positioned by the planer blade locating lugs on the set plate.
7. The blade’s lengthwise adjustment will need to be manually positioned
so that the blade ends are clear and equidistant from the housing on one
side and the metal bracket on the other.
8. Tighten the three hex flange head bolts (with the socket wrench pro-
vided) and rotate the drum to check clearances between the blade ends
and the tool body.
9. Check the three hex flange head bolts for final tightness.
10. Repeat procedures 1 - 9 for other blade.
For the correct planer blade setting
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 cutting edge is
absolutely level, that is, parallel to the surface of the rear base.

Connecting a vacuum cleaner
For tools with European type (round) chip cover
When you wish to perform clean planing operation, connect a Makita vacuum
cleaner to your tool as shown in the figure.
For tools with standard (non-round) chip cover
A nozzle and joint (optional accessories) are necessary to connect a Makita
vacuum cleaner to your tool. Consult a Makita catalogue or representative on
the nozzle and joint.
Nozzle assembly (optional accessory)
Use of the special nozzle assembly will minimize chip scatter, making for a
cleaner work area.

The nozzle assembly may be attached after the chip cover on the tool body is
removed. When slipping on the assembly, fit the pin on it into the rear cover
hole. Use the chip cover screws to fasten it in place.
OPERATION
Planing operation
First, rest the tool front base flat upon the workpiece surface without the
blades making 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. Planing will 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 in jamming by chips. For rough cut-
ting, 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.
Shiplapping (Rabbeting)
To make a stepped cut as shown in the figure, use the edge fence (guide rule).
Draw a cutting line on the workpiece. Insert the edge fence into the hole in the
front of the tool. Align the blade edge with the cutting line.

Adjust the edge fence until it comes in contact with the side of the workpiece,
then secure it by tightening the screw.
When planing, move the tool with the edge fence flush with the side of the
workpiece. Otherwise uneven planing may result.
Maximum shiplapping (rabbeting) depth is 9 mm.
You may wish to add to the length of the fence by attaching an extra piece of
wood. Convenient holes are provided in the fence for this purpose, and also for
attaching an extension guide (optional accessory).
Chamfering

MAINTENANCE CAUTION:
•Always be sure that the tool is switched off and unplugged before
attempting to perform inspection or maintenance.
Sharpening the planer blades
For standard blades only
Always keep your blades sharp for the best performance possible. Use the
sharpening holder 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 both blades contact the dressing stone for simulta-
neous sharpening at the same angle.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace when they wear
down to the limit mark. Keep the carbon brushes clean and free to slip in the
holders. Both carbon brushes should be replaced at the same time. Use only
identical carbon brushes.
