1. SAFETY
WARNING! Ensure Health & Safety, local authority, and general workshop practice regulations are adhered to when using this equipment.
WARNING! Disconnect from air supply before changing accessories or servicing.
Maintain the wrench in good condition and replace any damaged or worn parts. Use genuine parts only. Unauthorised parts may be
dangerous and will invalidate the warranty.
WARNING! Check correct air pressure is maintained and not exceeded. We recommend 90psi.
Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each use and ensure that all connections are secure.
Only use impact sockets which are specifi cally designed for use with an impact wrench.
Wear approved safety eye/face shield, ear defenders and hand protection.
WARNING! Due to the possible presence of asbestos dust from brake linings, when working around vehicle brake systems we
recommend you wear suitable respiratory protection.
Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.
Keep children and non-essential persons away from the working area.
8 DO NOT use the wrench for a task it is not designed to perform.
WARNING! DO NOT use wrench if damaged or thought to be faulty (contact Service Agent).
8 DO NOT use wrench unless you have been instructed in its use by a qualified person.
8 DO NOT carry the wrench by the air hose, or yank the hose from the air supply.
8 DO NOT operate wrench if you are tired or under the influence of alcohol, drugs or intoxicating medication.
8 DO NOT carry wrench with your hand on the trigger in order to avoid unintentional starting.
8 DO NOT direct air from the air hose at yourself or others.
When not in use disconnect from air supply 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 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): 4m/s²
Uncertainty value (k): 2m/s²
Please note that the application of the tool to a sole specialist task may produce a di erent average vibration emission. We recommend
that a specifi c 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 su cient 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.
1.1. HEALTH SURVEILLANCE
We recommend a programme of health surveillance to detect early symptoms of vibration injury so that management procedures can
be modifi ed accordingly.
1.2. 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 su cient supply of clothing (including gloves) to enable the operator to remain warm
and dry and maintain good blood circulation in fi ngers etc. Please note that the most e ective 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.

2. INTRODUCTION
Combination of composite materials, alloyed metals and twin hammer design, result in a lightweight, durable and powerful air impact
wrench. Composite handle helps reduce the eects of vibration and chill. Handle exhaust reduces noise output and limits the circulation of
brake dust on wheel applications. Fingertip Control of power and direction via lever on rear of wrench.

Drive: ................................................................... 1/2”Sq
Fastening Torque: ................................ 450lb-ft (610Nm)
Free Speed: ...................................................... 8500rpm
Inlet Size: ..........................................................1/4”BSP
Noise Power/Pressure: ............................... 107/96dB(A)
Operating Pressure: ............................................... 90psi

4. PREPARATION
4.1. Recommended hook-up is shown in fig 1.
4.2. Ensure that the wrench trigger is in the “O” position before connecting the air supply.
4.3. You will require an air pressure of 90psi and an air flow of 7cfm.
WARNING! Ensure that the air supply is clean and does not exceed 90psi. Too high an air pressure and/or unclean air will cause
excessive wear and may result in damage and/or personal injury.
4.4. Drain the compressor air tank daily. Water in the air line will damage the wrench.
4.5. Clean compressor air inlet filter weekly.
4.6. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). Hose internal diameter and the bores of
fittings should be 1/4” minimum.
4.7. Keep hose away from heat, oil and sharp edges. Before each use check hose for wear and make certain that all connections are secure.
5. OPERATION
WARNING! Ensure you read, understand and apply safety instructions before use.
5.1. Only use impact sockets which are specifically designed for use with an impact wrench.
8 DO NOT use worn or damaged sockets.
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, twist the switch on the rear of the wrench (fig.3), “anti-clockwise” for
reverse and “clockwise” for forward.
5.5. The flow of air may be regulated by the switch on the back of the wrench, there are three
settings in the forward position.
8 DO NOT use any additional force upon the wrench in order to loosen/tighten a fixing.
8 DO NOT allow wrench to free run for an extended period of time as this will shorten bearing
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. Unauthorised parts may be dangerous and will invalidate the warranty.
6.1. If the air system does not have an oiler then 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 grub screw located on the side of the body adjacent to the trigger.
6.3. Clean the wrench after use.
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. If your model has an air strainer (located in the area of the air
inlet), remove the strainer and clean it. Flush the wrench out with gum solvent oil or an equal mixture of SAE No 10 oil and paran.
6.5. Allow to dry before use.
6.6. For a full service contact your local Sealey service agent.
6.7. When not in use, disconnect from air supply, clean wrench and store in a safe, dry, childproof location.
