Cordless impact wrench safety 

warnings

1. 

Hold the power tool by insulated gripping 

surfaces, when performing an operation 

where the fastener may contact hidden wiring.

 

Fasteners contacting a "live" wire may make 

exposed metal parts of the power tool "live" and 

could give the operator an electric shock.

2. 

Wear ear protectors.

3. 

Check the impact socket carefully for wear, 

cracks or damage before installation.

4. 

Hold the tool firmly.

5. 

Keep hands away from rotating parts.

6. 

Do not touch the impact socket, bolt, nut or the 

workpiece immediately after operation.

 They 

may be extremely hot and could burn your skin.

7. 

Always be sure you have a firm footing.

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.

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

Important safety instructions for 

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 atten-

tion right away. It may result in loss of your 

eyesight.

5. 

Do not short the battery cartridge:

(1) 

Do not touch the terminals with any con-

ductive material.

Avoid storing battery cartridge in a con-

tainer 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.

6. 

Do not store the tool and battery cartridge in 

locations where the temperature may reach or 

exceed 50 °C (122 °F).

7. 

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.

8. 

Be careful not to drop or strike battery.

9. 

Do not use a damaged battery.

10. 

The contained lithium-ion batteries are subject 

to the Dangerous Goods Legislation require-

ments. 

For commercial transports e.g. by third parties, 

forwarding agents, special requirement on pack-

aging and labeling must be observed. 

For preparation of the item being shipped, consult-

ing an expert for hazardous material is required. 

Please also observe possibly more detailed 

national regulations. 

Tape or mask off open contacts and pack up the 

battery in such a manner that it cannot move 

around in the packaging.

it from the tool and dispose of it in a safe 

place. Follow your local regulations relating to 

disposal of battery.

12. 

Use the batteries only with the products 

specified by Makita.

 Installing the batteries to 

non-compliant products may result in a fire, exces

-

sive heat, explosion, or leak of electrolyte.

13. 

If the tool is not used for a long period of time, 

the battery must be removed from the tool.

SAVE THESE INSTRUCTIONS.

CAUTION:

 

Only use genuine Makita batteries.

 

Use of non-genuine Makita batteries, or batteries that 

have been altered, may result in the battery bursting 

causing fires, personal injury and damage. It will 

also void the Makita warranty for the Makita tool and 

charger.

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 car-

tridge. Overcharging shortens the battery 

service life.

3.

perature at 10 °C - 40 °C (50 °F - 104 °F). Let 

a hot battery cartridge cool down before
