DX-100 ½" Drive Impact Wrench / Rattle Gun

E&OE

Guidelines for Use

Fully understand all operational

safety warnings

before using the tool.

•

Always use the correct socket for the fastener size.

•

Always torque to the required value

– do NOT over-tighten.

•

When tightening, wait for the drive pin to disengage

– this means that the set torque has been reached.

•

Always hold the tool "square" to the fastener. That is, screw straight. Do not apply sideways pressure to
the tool.

•

Apply sufficient pressure to prevent the socket slipping from the fastener head.

Maintenance and Troubleshooting

Disconnect the tool from the electrical supply before performing any mainten

ance. • The

machine should be cool enough to touch before performing maintenance activities. • Some

maintenance activities described may be beyond the scope of some users. For procedures that you are not
comfortable with or have the tools, knowledge or experience for, have the unit serviced by an authorised
service centre or qualified technician.

•

Clean the tool regularly with a soft cloth

– do NOT use water, solvents, abrasives etc. Remove any

debris from the drive pin and tool ventilation slots using a soft brush.

Motor Brushes

The electric motor uses 2 carbon "brushes" in order to function. The brushes wear as a result of use

– this is

normal, and some tools may come with replacement brushes. If the brushes are allowed to wear past the
acceptable limit, the motor may produce less power, operate intermittently, or not operate at all. To check
brushes:

1. Clean the tool in the area under the brush covers to help prevent any dirt or other material entering the

motor housing.

2. Use a coin or wide flat blade screwdriver to remove the brush cap (

3. Pull the brush (

) from the cavity and check the length of the carbon section (

). If the brush length is

close to the minimum acceptable limit (7mm), replace the brush

– always replace both brushes at the

same time.

4. Insert the brush into the cavity.

5. Re-install the brush cap (rotate right. Do not over-tighten).
