4. PREPARATION
4.1. Air Supply.
4.1.1. Ensurewrenchairvalve(ortrigger)isinthe“o󰀨”positionbeforeconnectingtotheairsupply.
4.1.2. 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.
4.1.3. Drain the air tank daily. Water in the air line will damage the wrench.
4.1.4. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig.1.

4.1.5. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be
3/8 ” I.D. and fittings must have the same inside dimensions.
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.
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.
5. OPERATION
WARNING! Ensure you read, understand and apply safety instructions before use.
5.1.  Onlyuseimpactsocketswhicharespecicallydesignedforusewithanimpactwrench.
5.2. Connect the wrench to the air hose as in section 4.
5.3. Place the socket over the subject nut and depress the trigger to operate the wrench.
5.4. To change direction turn the reverse lever.
5.5. The flow of air may be regulated by adjusting flow valve below the trigger.
8DO NOT use any additional force upon the wrench in order to remove a nut.
8DO NOT allow wrench to free run for an extended period of time as this will shorten its life.
6. MAINTENANCE
WARNING! Disconnect wrench from air supply before changing accessories, servicing or performing maintenance. Replace or repair
damaged parts. Use genuine parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
6.1. Lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet.
6.2. Check and top up the gearbox by removing the set screw (item 13 on the parts diagram).
6.3. Clean the wrench after use. DO NOT use worn, or damaged sockets.
6.4. Loss of power or erratic action may be due to the following:
a) Excessive drain on the air line. Moisture or restriction in the air pipe. Incorrect size or type of hose connectors. To remedy
check the air supply and follow instructions in section 4.
b) Grit or gum deposits in the wrench may also reduce performance. Remove the strainer, clean it and flush the wrench out with
gum solvent oil or an equal mixture of SAE No 10 oil and paraffin. Allow to dry before use.
6.5. For a full service contact your local Sealey stockist.
6.6. When not in use, disconnect from air supply, clean wrench and store in a safe, dry, childproof location
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 to be operated in accordance with these instructions.
Measured vibration emission value (a): .....6.28m/s²
Uncertainty value (k): .....................2.5m/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 factors include; 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.
