1/2" AIR RATCHET WRENCH
Air ratchet wrench safety instructions
1. Always use the ratchet wrench in the manner and for the functions described in this
manual.
2. Always ensure the wrench is not moving and disconnected from the air supply
when changing sockets etc. Only use impact sockets. Do not use standard
sockets.
3. Always finish tightening threaded fasteners, bolts or nuts, or engine parts with a
calibrated torque wrench by hand to the correct torque as recommended by the
manufacturer where critical torque values are required.
4. Where critical torque values are not required, the final tightening of threaded
fasteners, bolts or nuts can be slightly tighter if gaskets are used between surfaces.
5. Use penetrating oil to assist in freeing off rusted fasteners, bolts and nuts if
necessary.
6. When assembling, first turn fasteners, bolts or nuts by hand onto workpiece. Then
start the tool for tightening.
7. Always ensure that the socket is correctly installed onto the tool anvil before
starting the tool.
8. Never carry the ratchet wrench by the air supply hose.
9. Always disconnect the tool from the air supply when changing sockets or when the
wrench is not required for immediate use in order to avoid accidental start.
10. Always ensure that the wrench has come to a complete stop before putting it
down after use.
11. If necessary, use clamps or proper devices to securely fix the workpiece when
installing/tightening or removing/loosening threaded fasteners on the workpiece.
12. For overhead work, wear a safety helmet.

your hands or arms. Stop using the tool if discomfort, a tingling feeling or pain
occurs. Resume work after recovery. Seek medical advice if a serious symptom
