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.

The proper fastening torque may differ 

depending upon the kind or size of the bolt. 

Check the torque with a torque wrench.

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.
