IMPORTANT SAFETY INSTRUCTIONS FOR
CHARGER & BATTERY CARTRIDGE

1. Before using battery cartridge, read all instruc-

tions and cautionary markings on (1) battery
charger, (2) battery, and (3) product using bat­tery.

2. Do not disassemble battery cartridge.

3. If operating time has become excessively

shorter, stop operating immediately. It may
result in a risk of overheating, possible burns
and even an explosion.

4. If electrolyte gets into your eyes, rinse them out

with clear water and seek medical attention right
away. It may result in loss of your eyesight.

5. Always cover the battery terminals with the bat-

tery cover when the battery cartridge is not
used.

6. Do not short the battery cartridge:

(1) Do not touch the terminals with any conduc-

tive material.

(2) Avoid storing battery cartridge in a container

with other metal objects such as nails, coins,
etc.

(3) Do not expose battery cartridge to water or

rain.
A battery short can cause a large current flow,
overheating, possible burns and even a break­down.

7. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).

ENC004-1

8. Do not incinerate the battery cartridge even if it
is severely damaged or is completely worn out.
The battery cartridge can explode in a fire.

9. Be careful not to drop or strike battery.

SAVE THESE INSTRUCTIONS.

Tips for maintaining maximum battery life

1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat­tery cartridge when you notice less tool power.

2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.

3. Charge the battery cartridge with room tempera­ture at 10°C – 40°C (50°F – 104°F). Let a hot bat­tery cartridge cool down before charging it.

4. Charge the Nickel Metal Hydride battery car­tridge when you do not use it for more than six
months.

ADDITIONAL SAFETY RULES FOR TOOL

1. Be aware that this tool is always in an operating
condition, because it does not have to be
plugged into an electrical outlet.

2. Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring. Contact with a “live”
wire will also make exposed metal parts of the
tool “live” and shock the operator.

3. Wear ear protectors.

4. Check the socket carefully for wear, cracks or
damage before installation.

5. Hold the tool firmly.

6. Always be sure you have a firm footing.

7. Be sure no one is below when using the tool in
high locations.

8. The proper fastening torque may differ depend­ing upon the kind or size of the bolt. Check the
torque with a torque wrench.

OPERATING INSTRUCTIONS

Installing or removing battery cartridge (Fig. 1)

• Always switch off the tool before insertion or removal of
the battery cartridge.

• To remove the battery cartridge, withdraw it from the
tool while pressing the push buttons on both sides of
the cartridge.

• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.

• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.

Selecting correct socket

Always use the correct size socket for bolts and nuts. An
incorrect size socket will result in inaccurate and inconsi­stent fastening torque and/or damage to the bolt or nut.

Installing or removing socket (Fig. 2)

Important:
Always be sure that the tool is switched off and the bat­tery cartridge is removed before installing or removing
the socket.

Move the O-ring out of the groove in the socket and
remove the pin from the socket. Fit the socket onto the
anvil of the tool so that the hole in the socket is aligned
with the hole in the anvil. Insert the pin through the hole
in the socket and anvil. Then return the O-ring to the ori­ginal position in the socket groove to retain the pin. To
remove the socket, follow the installation procedures in
reverse.

Switch action (Fig. 3)

CAUTION:
Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the “OFF” position when released.

To start the tool, simply pull the trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.

Reversing switch action (Fig. 4)

CAUTION:

• Always check the direction of rotation before operation.

• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.

This tool has a reversing switch to change the direction
of rotation. Slide the reversing switch to the left for
clockwise rotation or to the right for counterclockwise
rotation.

Operation (Fig. 5 & 6)

The proper fastening torque may differ depending upon
the kind or size of the bolt. The relation between faste­ning torque and fastening time is shown in the figures.

Hold the tool firmly and place the socket over the bolt or
nut. Turn the tool on and fasten for the proper fastening
time.

NOTE:

• Hold the tool pointed straight at the bolt or nut without
applying excessive pressure on the tool.

• Excessive fastening torque may damage the bolt or
nut. Before starting your job, always perform a test
operation to verify the adequate fastening speed and
time for your bolt or nut.

The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.

1. When the battery cartridge is discharged almost

completely, voltage will drop and the fastening
torque will be reduced.

2. Socket

• Failure to use the correct size socket will cause a
reduction in the fastening torque.

• A worn socket (wear on the hex end or square
end) will cause a reduction in the fastening
torque.

3. Bolt

• Even though the torque coefficient and the class
of bolt are the same, the proper fastening torque
will differ according to the diameter of the bolt.

• Even though the diameters of bolts are the same,
the proper fastening torque will differ according to
the torque coefficient, the class of bolt and the
bolt length.

4. The use of the universal joint or the extension bar
somewhat reduces the fastening force of the impact
wrench. Compensate by fastening for a longer
period of time.

5. Type of materials to be fastened, the manner of hol­ding the tool and the tool speed will affect the torque.

CAUTION:
If the tool is operated continuously until the battery cartri­dge has discharged, allow the tool to rest for 15 minutes
before proceeding with a fresh battery.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the bat­tery cartridge is removed before carrying out any work on
the tool.

To maintain product safety and reliability, repairs, mainte­nance or adjustment should be carried out by a Makita
Authorized Service Center.
