MIGHTY COMPACT
½” IMPACT WRENCH
PREPARING WRENCH FOR USE
Air Supply
Ensure wrench air valve (or trigger) is in the “off” position
before connecting to the air supply. According to
specifications your wrench requires an air pressure of
90 psi.
• Drain the compressor air tank daily as water in the air line
will damange the wrench.
• Clean compressor air inlet filter weekly.
• Line pressure should be increased to compensate for
unusually long air hoses (over 8 meters).
• The minimum hose diameter should be 3/8”.
• Keep hose away from heat, oil and sharp edges.
• Check hose for wear,and make certain that all
connections are secure.
Couplings
Vibration may cause failure if a quick change coupling
is connected directly to the wrench. To overcome this,
connect a leader hose to the wrench. A quick change
coupling may then be used to connect the leader hose to
the air line recoil hose.
OPERATING INSTRUCTIONS:
WARNING
Ensure you read, understand and apply safety
instructions before use.
1. Only use impact sockets which are specifically
designed for use with an impact wrench.
2. Connect the wrench to the air hose.
3. Place the socket over the fastener nut and depress
the trigger to operate the wrench.
4. The Forward Reverse Valve is located on the
back of the Impact. Simply
move the valve right or left to
change direction.
DO NOT allow wrench to free run for an exdtended period
of time as this will reduce bearing life.
MAINTENANCE
WARNING
Disconnect wrench from air supply before changing
accessories, servicing or performing maintenance.
1. Replace or repair damaged parts. Use genuine
parts only. Unauthorized parts may be dangerous
and will invalidate the warranty.
2. If the air system does not have an oiler then
lubricate the Impact Wrench daily with a few drops
of air tool oil into the air inlet.
3. Clean the wrench after use.
4. DO NOT use worn, or damaged sockets.
