DOUBLE INSULATION
Only for EU countries
Do not dispose of electric equipment
together with household waste material! In
observance of the European Directive, on
Waste Electric and Electronic Equipment
and its implementation in accordance with
national law, electric equipment that have
reached the end of their life must be col-
lected separately and returned to an envi-
ronmentally compatible recycling facility.
Intended use
The tool is intended for planing wood.
Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and
can only be operated on single-phase AC supply. They
are double-insulated and can, therefore, also be used
from sockets without earth wire.
Noise
The typical A-weighted noise level determined accord-
ing to EN60745:
Sound pressure level (LpA) : 85 dB(A)
Sound power level (LWA) : 96 dB (A)
Uncertainty (K) : 3 dB(A)
WARNING: Wear ear protection.
Vibration
The vibration total value (tri-axial vector sum) deter-
mined according to EN60745:
Work mode: planing softwood
Vibration emission (ah) : 3.5 m/s2
Uncertainty (K) : 1.5 m/s2
NOTE: The declared vibration emission value has
been measured in accordance with the standard test
method and may be used for comparing one tool with
another.
NOTE: The declared vibration emission value
may also be used in a preliminary assessment of
exposure.
WARNING: The vibration emission during actual
use of the power tool can differ from the declared
emission value depending on the ways in which the
tool is used.
WARNING: Be sure to identify safety measures
to protect the operator that are based on an estima-
tion of exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as

General power tool safety warnings
WARNING: Read all safety warnings and
all instructions. Failure to follow the warnings and
instructionsmayresultinelectricshock,reand/or
seriousinjury.
Save all warnings and instruc-
tions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical Safety
1. 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. Unmodiedplugsandmatchingoutletswill
reduce risk of electric shock.
2. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
4. 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.
5. 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.
6. If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
7. Use of power supply via an RCD with a rated
residual current of 30 mA or less is always
recommended.
Personal Safety
1. 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 inuence of drugs, alcohol or med-
ication. A moment of inattention while operating
powertoolsmayresultinseriouspersonalinjury.
2.
Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for appropri-
ateconditionswillreducepersonalinjuries.
3. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
yourngerontheswitchorenergisingpowertools
that have the switch on invites accidents.
4. 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.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts.Looseclothes,jewel-
lery or long hair can be caught in moving parts.
7. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
Power tool use and care
1. 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.
2. 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.
3. 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 pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
4. 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.
5. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing into account the working conditions and
the work to be performed. Use of the power tool
for operations different from those intended could
result in a hazardous situation.
Service
1. Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
2. Follow instruction for lubricating and changing
accessories.
3. Keep handles dry, clean and free from oil and grease.

4ENGLISH
Planer safety warnings
1. Wait for the cutter to stop before setting the
tool down. An exposed rotating cutter may
engage the surface leading to possible loss of
controlandseriousinjury.
2. Hold the power tool by insulated gripping
surfaces only, because the cutter may contact
its own cord. Cutting a "live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
3. Use clamps or another practical way to secure
and support the workpiece to a stable plat-
form. Holding the work by your hand or against
the body leaves it unstable and may lead to loss of
control.
4. Rags, cloth, cord, string and the like should
never be left around the work area.
5. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
6. Use only sharp blades. Handle the blades very
carefully.
7. Be sure the blade installation bolts are
securely tightened before operation.
8. Hold the tool rmly with both hands.
9. Keep hands away from rotating parts.
10. 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.
11. Make sure the blade is not contacting the
workpiece before the switch is turned on.
12. Wait until the blade attains full speed before
cutting.
13. Always switch off and wait for the blades to
come to a complete stop before any adjusting.
14. Never stick your nger into the chip chute.
Chute may jam when cutting damp wood.
Clean out chips with a stick.
15. Do not leave the tool running. Operate the tool
only when hand-held.
16. Always change both blades or covers on the
drum, otherwise the resulting imbalance will
cause vibration and shorten tool life.
17. Use only Makita blades specied in this
manual.
18. Always use the correct dust mask/respirator
for the material and application you are work-
ing with.
SAVE THESE INSTRUCTIONS.
WARNING: DO NOT let comfort or familiarity
with product (gained from repeated use) replace
strict adherence to safety rules for the subject
product. MISUSE or failure to follow the safety
rules stated in this instruction manual may cause
serious personal injury.
