4. AIR SUPPLY
WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the wrench. Too high an air pressure and/or unclean
air will shorten the product life due to excessive wear, and may be dangerous causing damage and/or personal injury.
4.1. AIR SUPPLY
4.1.1. Ensure the wrench trigger is not depressed when connecting to the air supply.
4.1.2. You will require an air pressure of 90psi, and an air flow according to specification.
4.1.3. Drain your compressor air tank of water daily. Water in the air line will damage the wrench.
4.1.4. Clean the compressor air inlet filter weekly. Recommended hook-up procedure is shown in (fig.2); see also section 4.2.
4.1.5. Line pressure should be increased to compensate for unusually long recoil air hoses (over 8 metres). The minimum supply pipework

should be 1/2” I.D.
NOTE: The impact wrench requires a 1/4” BSP fitting.
4.1.6. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
4.2. COUPLINGS
4.2.1. 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 (g.2 & 3).

5. OPERATION
WARNING! Ensure you read, understand and apply safety instructions before use.
NOTE: Only use impact sockets which are specically designed for use with a impact wrench.
5.1. Connect the wrench to the air hose as in section 4.
5.2. Place the socket over the subject nut and depress the trigger to operate the wrench.
5.3. To change direction push the button at the rear of the head assembly.
5.4. The ow of air may be regulated by turning the same button.
8 DO NOT use any additional force upon the wrench in order to remove a nut.

repair damaged parts. Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
6.1. If the air system does not have an oiler, lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet.
6.2. The gearbox can be lubricated by greasing via the nipple on the rear of the wrench head.

HAND ARM VIBRATION
WARNING! – RISK OF HAND ARM VIBRATION INJURY.
This tool may cause Hand Arm Vibration Syndrome if its use is not managed adequately.
This tool is subject to the vibration testing section of the Machinery Directive 2006/42/EC.
This tool is to be operated in accordance with these instructions.
Measured vibration emission value (a): 5.47
m/s²
Uncertainty value (k):
1.5m/s²
Please note that the application of the tool to a sole specialist task may produce a different average vibration emission. We recommend
that a specific evaluation of the vibration emission is conducted prior to commencing with a specialist task.
A health and safety assessment by the user or employer will need to be carried out to determine the suitable duration of use for each tool.
NB: Stated Vibration Emission values are type-test values and are intended to be typical.
Whilst in use, the actual value will vary considerably from and depend on many factors, such as the operator, the task and the inserted
tool or consumable.
NB: ensure that the length of leader hoses is sufficient to allow unrestricted use, as this also helps to reduce vibration.
The state of maintenance of the tool itself is also an important factor, a poorly maintained tool will also increase the risk of Hand Arm
Vibration Syndrome.
HEALTH SURVEILLANCE
We recommend a programme of health surveillance to detect early symptoms of vibration injury so that management procedures can be
modified accordingly.
PERSONAL PROTECTIVE EQUIPMENT
We are not aware of any personal protective equipment (PPE) that provides protection against vibration injury that may result from the
uncontrolled use of this tool. We recommend a sufficient supply of clothing (including gloves) to enable the operator to remain warm and
dry and maintain good blood circulation in fingers etc. Please note that the most effective protection is prevention, please refer to the
Correct Use and Maintenance section in these instructions. Guidance relating to the management of hand arm vibration can be found on
the HSC website www.hse.gov.uk - Hand-Arm Vibration at Work.
