INSTALLING FASTENERS

NOTE: Always keep the Impact Wrench at a right angle to the fastener to avoid

damaging the fastener head.

To fasten:

Start threading the fastener by hand onto or into its threaded counterpart

(e.g. nut onto bolt, or bolt into nut or threaded hole).

2. With the proper impact socket securely mounted to the wrench, slide the

impact socket onto the nut or bolt head.

3 Hold the tool securely with both hands and depress the switch at '_j.

The impact socket will turn the fastener and impacting will begin once the

fastener encounters resistance.

A_, WARNING: Do not over-tighten, as the force of the Impact Wrench can

break the fastener.

To loosen:

With the proper impact socket securely mounted to the wrench, slide the

impact socket onto the bolt head.

Hold the tool securely with both hands and depress the switch at _.. The

tool will start to impact immediately.

Once the fastener has "broken loose," it will start to unthread. Be careful that

you do not allow a fastener to spin freely once it is no longer engaged with

its threaded counterpart, as it may be thrown out of the socket.

IMPACTING TECHNIQUES

The proper fastening torque may differ depending on the type or size of the bolt,

the material of the workpiece to be fastened, etc.

NOTE: Hold the tool straight along the axis of the bolt or nut.

NOTE: Excessive fastening torque may damage the bolt/nut or socket. Before

starting your job, always perform a test operation to determine the proper

fastening time for your bolt or nut.

Practice with various fasteners, noting the length of time required to reach the

desired torque. Check the tightness with a hand-torque wrench. If the fasteners

are too tight, reduce the impacting time. If they are not tight enough, increase

the impacting time.

Hold the tool firmly, and place the socket over the bolt or nut. Turn the tool on,

and fasten the bolt or nut to the proper torque.

The torque that is required to loosen a fastener averages 75% to 80% of the

tightening torque, depending on the condition of the contacting surfaces.

However, if rust or corrosion causes seizing, more torque may be required.
