1. SAFETY INSTRUCTIONS
Follow all workshop safety rules, regulations, and conditions when using wrench.
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. Non-authorised 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 specifically 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.
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).

3. PREPARING WRENCH FOR USE
3.1. Air Supply
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.
3.1.3. WARNING! Ensure that the air supply is clean and does not exceed 90 psi whilst
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.
3.1.4. Drain the air tank daily. Water in the air line will damage the wrench.
3.1.5. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig.1.
3.1.6. 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.
3.1.7. 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 figs.1 & 2).

4. 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 direction push the button at the top of the handle. Direction of “R” for reverse and
“F” for forward
4.5. The flow of air may be regulated by adjusting the flow valve at the base of the handle.
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.
5. MAINTENANCE
WARNING!Disconnect the wrench from the air supply before changing accessories,
servicing or performing any maintenance.Replace or repair damaged parts. Use genuine
parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
5.1. Lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet.
5.2. Check and top up the gearbox by removing grub screw located under the impact head.
5.3. Clean the wrench after use.

5.4. DO NOT use worn or damaged sockets.
5.5. 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
chapter 3.
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 paraffin.
Allow to dry before use.
5.6. For a full service, contact your local Sealey service agent.
5.7. When not in use, disconnect from the air supply, clean wrench and store it in a safe, dry,
childproof location.
WARNING! - Risk of Hand Arm Vibration Injury.
This tool is subject to the vibration testing section of the Machinery Directive 2006/42/EC. When operated in
accordance with these instructions and tested in accordance with the standard below, results in the following
vibration emission declared in accordance with EN 12096:1997
Model No:
Tested in Accordance with: BS EN ISO 28927-2:2009
Measured Vibration Emission Value (a): 5
Uncertainty value (k): 0
These values are suitable for comparison with the vibration emission levels of other tools that have been
obtained using the same test method.
This tool may cause hand-arm vibration syndrome if its use is not adequately managed.
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. Note that the value declared is an average figure from a series of tests according
to the applicable standard. The value may differ depending on a number of variables including but not limited
to; the user; the condition of the tool; attachments made to the tool i.e. sockets, grinding/cutting discs, sanding
discs, blades, handles, leader hoses (always recommended as this helps to reduce vibration).
Correct use and maintenance.
The vibration emission is closely linked to the operating pressure in the air supply. You should ensure that the
pressure is set in accordance with our recommendations to assure optimum efficiency with minimised vibration
exposure.
Health surveillance.
We recommend a programme of health surveillance to detect early symptoms of vibration injury so that
management procedures can be modified to help prevent significant handicap.
Personal protective equipment.
We are not aware of any personal protective equipment (PPE) that provides protection against vibration injury
by attenuating the vibration emissions 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.
Guidance relating to the management of hand arm vibration can be found on the HSC website www.hse.gov.uk
