Risk of Hand Arm Vibration Injury.
The SA6.V2 Super Duty Air Impact Wrench, when operated in accordance with these instructions and tested in accordance with
EN 28662-2: 1994 results in the following vibration emission declared in accordance with BS EN12096: 1996.
Measured vibration emission value: .................... 4.4m/s²
These values are suitable for comparison with emission levels of other tools that have been subject to the same test.
This tool may cause hand-arm vibration syndrome if its use is inadequately managed.
Recommended Measures to reduce risk of hand-arm vibration syndrome:
This tool should not be used by an individual regularly for more than 5.27 hours in any 8 hour period.
This duration of use should be reduced if the individual is exposed to hand-arm vibration from other sources.

PREPARING WRENCH FOR USE
3.1.
Air Supply
Recommended hook-up is shown in fig 1.
3.1.1. Ensure wrench air valve (or trigger) is in the "off" position before connecting to the air
supply.
3.1.2. You will require an air pressure of 90psi, and an air flow according to specification.
WARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the
wrench. Too high an air pressure and unclean air will shorten the product life due to
excessive wear, and may be dangerous causing damage and/or personal injury.
3.1.3 Drain the air tank daily. Water in the air line will damage the wrench.
3.1.4. Clean air inlet filter weekly.
3.1.5. Line pressure should be increased to compensate for unusually long air hoses (over 8
metres). The minimum hose diameter should be 1/4" I.D. and fittings must have the same
inside dimensions.
3.1.6. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain
that all connections are secure.
3.2. 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. See fig 1 & 2.

OPERATING INSTRUCTIONS
WARNING! Ensure you read, understand and apply safety instructions before use.
4.1.
Only use impact sockets which are specifically designed for use with an impact wrench.
4.2.
Connect the wrench to the air hose as in Section 3.
4.3.
Place the socket over the subject nut and depress the trigger to operate the wrench.
4.4.
To change drive direction push the reverse valve button at the top of the handle.
4.5.
The flow of air may be regulated by adjusting the twist dial at the rear of the handle,
between 1 low power and 4 full power.
DO NOT use any additional force upon the wrench in order to remove a nut.
DO NOT allow wrench to free run for an extended period of time as this will shorten its life.
