Air impact wrench safety instructions
1. Always use the impact wrench in the manner and for
the functions described in this manual.
2. Always ensure the wrench is not moving and discon-
nected from the air supply when changing sockets etc.
Only use impact sockets. Do not use standard sock-
ets.
3. Always finish tightening wheel nuts or engine parts
with a torque wrench or suitable spanner to the
correct torque as recommended by the vehicle
manufacturer.
4. Always avoid excessive use of the impact wrench.
When tightening a nut or bolt, never allow the wrench
to impact more than 8 times. This is to avoid over-
tightening. 3 to 4 impacts is normally sufficient.
5. Always ensure that the socket is correctly installed
onto the tool anvil before starting the tool.
6. Due to the possible presence of asbestos dust from
brake linings, always wear suitable respiratory
protection.
7. Never carry the impact wrench by the air supply hose.
8. Always disconnect the tool from the air supply when
changing impact sockets or when the wrench is not
required for immediate use in order to avoid acciden-
tal start.
9. Hold the tool correctly. Always use both hands to
control the impact wrench.
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.
13. Do not discard the Operator's Manual. It contains
safety instructions.
14. Always store this product in a dry and safe place out
of reach of children or untrained operators.
5. Drain water from the air compressor tank daily, as
well as any condensation in the air lines. Water in the
air line may enter the tool and cause damage to the
tool mechanisms during operation.
6. Clean the tool air inlet screen filter for blockage
weekly. Clean if necessary.
7. A 3/8" (inner diameter) air hose is recommended for
air supply and airflow to get the optimum perfor-
mance of tool.
8. A long air hose (usually over 26 ft/8 m) may cause up
to 15 PSI/1.1 bar drop in pressure, so you need to set
the output pressure of the air compressor higher to
maintain the required working pressure at the tool.
9. Use proper hoses and fittings. It is not recommended
to use quick change couplings directly on the tool.
Tool vibration may cause damage or tool failure.
Instead, use a lead hose that can connect directly to
the tool, and a connect coupling between the air
supply and hose.
10. Check the hoses for wear or defects before each use.
Make certain that all connections are secure.
11. An individual air tool has its specification of air
consumption (CFM). Check the specifications of your
compressor to be sure that it can support both the
minimum CFM and PSI required.
Air Supply
1. Use only clean, dry, regulated compressed air as the
power source.
2. Make sure that the air compressor being used for the
tool operation supplies the correct output (CFM).
3. Have the tool in the "off" position when connecting
the tool to the air supply.
4. Use 90 PSI/6.3 bar working pressure for the tool.
High pressure and unclean air will shorten the life of
the tool due to faster wear of the tool.
WARNING
Read and understand the air compres-
sor instruction manual thoroughly before using the
tool. It contains important safety information pertain-
ing to the use of the air compressor and air hoses.
NOTE
Working pressure refers to the air line pressure
set to the tool when the tool is under working conditions.
Terms used throughout this manual are Cubic Feet per
Minute (CFM) and Pounds per Square Inch (PSI).

mended below.
