SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications provided
with this power tool. Failure to follow all instructions
listed below 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. Power tools can produce electromagnetic
elds (EMF) that are not harmful to the user.
However, users of pacemakers and other similar
medical devices should contact the maker of their
device and/or doctor for advice before operating
this power tool.
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 a dust mask, non-skid safety shoes, hard hat or
hearing protection used for appropriate conditions
will reduce personal injuries.
3. Prevent unintentional starting. Ensure the
switch is in the o󰀨-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 and clothing away
from moving parts. Loose clothes, jewellery 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.
8. Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore tool safety principles. A careless action
can cause severe injury within a fraction of a
second.

4ENGLISH
9. Always wear protective goggles to protect
your eyes from injury when using power tools.
The goggles must comply with ANSI Z87.1 in
the USA, EN 166 in Europe, or AS/NZS 1336
in Australia/New Zealand. In Australia/New
Zealand, it is legally required to wear a face
shield to protect your face, too.
It is an employer's responsibility to enforce
the use of appropriate safety protective equip-
ments by the tool operators and by other per-
sons in the immediate working area.
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 o󰀨. 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 remove the battery pack, if detachable,
from the power tool before making any adjust-
ments, changing accessories, or storing power
tools. Such preventive 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 and accessories. Check for
misalignment or binding of moving parts, break-
age of parts and any other condition that may
a󰀨ect 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 di󰀨erent from those intended could
result in a hazardous situation.
8. Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for
safe handling and control of the tool in unexpected
situations.
9. When using the tool, do not wear cloth work
gloves which may be entangled. The entangle-
ment of cloth work gloves in the moving parts may
result in personal injury.
Battery tool use and care
1. Recharge only with the charger specied by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of re
when used with another battery pack.
2. Use power tools only with specically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and re.
3. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from one
terminal to another. Shorting the battery termi-
nals together may cause burns or a re.
4. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If con-
tact accidentally occurs, ush with water. If
liquid contacts eyes, additionally seek medical
help. Liquid ejected from the battery may cause
irritation or burns.
5. Do not use a battery pack or tool that is dam-
aged or modied. Damaged or modied batteries
may exhibit unpredictable behaviour resulting in
re, explosion or risk of injury.
6. Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or tem-
perature above 130 °C may cause explosion.
7. Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specied in the instruc-
tions. Charging improperly or at temperatures
outside the specied range may damage the
battery and increase the risk of re.

Ejection of air
If air remains in the ow path of the grease, the tool
cannot pour grease accurately. Eject the air before each
use and also when the tool seems to work improperly
due to air.
1. To eject air from inside of the tool, loosen the valve
for air drain. Air comes out from the hole for air
drain.
2. Fasten the valve when you see the grease coming
out of the hole.

WARNING: Wear the protective goggles when
ejecting the air.
CAUTION: Wipe o󰀨 the grease that comes
out from the air drain with a dry cloth or the like.
Otherwise it may cause slipping and result in an
injury.
Dispensing the grease
In the following cases, purge the old grease inside the
tool before use;
— When using the tool for the rst time or;
— When using di󰀨erent type of the grease from
previous use.
With the new grease lled in the barrel, run the tool
for a while until the old grease is pushed out from the
adapter.
NOTICE: Do not connect the adapter to the
grease nipple until the old grease is purged. If
di󰀨erent kinds of grease are mixed, the performance
of the grease may decline.
NOTE: The tool has been tested at the factory and
small amount of the grease remains.
Perform the following procedure to dispense the
grease.
CAUTION: Always check the speed mode
before operation.
NOTICE: Before connecting the adapter to the
grease nipple, always make sure that the tool
dispenses grease properly.
NOTICE: Do not connect the adapter to the
grease nipple forcibly.
1. Wipe the adapter and the grease nipple before
connecting. Push the adapter straight at the
grease nipple.
2. Pull the switch trigger to dispense the grease.
3. When dispensing the grease is nished, remove
the adapter from the grease nipple. Tilt the
adapter slightly to release internal pressure and
then remove the adapter from the grease nipple.
Wipe o󰀨 the grease from the adapter and the
grease nipple.
NOTICE: Do not leave the tool running even after
the grease depleted. It may shorten the life of the
tool.
NOTE: If the internal pressure rises while the switch
trigger is not fully pulled, the protection system works
and the motor will stop even though the tool does
not reach the maximum operating pressure. When
injecting the grease at high pressure, pull the switch
trigger fully.
NOTE: The tool stops automatically when the tool
keep running for more than 6 minutes.
MAINTENANCE
CAUTION: Always be sure that the tool is
switched o󰀨 and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
