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. pWARNING! 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.
3.1.4. 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 figures 1 and 2.
3. PREPARING WRENCH FOR USE
4. OPERATING INSTRUCTIONS
pWARNING! Ensure you read, understand and apply safety instructions before use.
4.1. Only use impact sockets which are specifically designed for use with a impact wrench.
4.2. Connect the wrench to the air hose as in chapter 3.
4.3. Place the socket over the subject nut and depress the trigger to operate the wrench.
4.4. To change direction turn the lever on the back body housing.
4.5. The flow of air may be regulated by turning the knob 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.

p 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.
5.1. Lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet
to prolong its life.
5.2. Clean the wrench after use. DO NOT use worn, or damaged sockets.
5.3. 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.
5.4. For a full service contact your local Sealey service agent.
5.5. 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): ................. 10.3m/s²
Uncertainty value (k):................................. 1.51m/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.
PREPARING FOR USE.
Air Supply.
WARNING!
Ensure the air supply is clean and does not exceed 90psi while operating the tool.
Too high an air pressure and unclean air will shorten the product life due to excessive wear and may cause damage and/or
personal injury.
Ensure that the tool air valve (or trigger) is in the “off” position before connecting to the air supply.
Monitor the compressor daily to ensure that moisture is not present in the compressed air. Water in the air line will damage the tool.
Line pressure should be increased to compensate for unusually long air hoses (over 8metres).
The minimum hose diameter should be ¼” internal diameter. Fittings must have compatible inside dimensions.
Keep hoses away from heat, oil and sharp edges. Check hoses for wear and ensure that all connections are secure.
Couplings.
Vibration may cause failure if a quick change coupling is connected directly to the tool.
To overcome this, connect a leader hose to the tool (Sealey ref: AH2R or AH2R/38).
A quick change coupling may then be used to connect the leader hose to the air line recoil hose.
CORRECT USE.
Vibration emission is closely linked to the operating pressure in the air supply. The user should ensure that the pressure is set in
accordance with our recommendations to assure optimum efficiency and minimise vibration exposure.

MAINTENANCE.
If the air system does not have an oiler, lubricate the air tool daily with a few drops of Sealey air tool oil dripped into the air inlet.
Clean the tool after use.
DO NOT use worn or damaged grinding discs (if applicable).
Loss of power or erratic action may be due to the following:
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 the PREPARING FOR USE section.
Grit, residual deposits (gum) in the tool may also reduce performance.
Remove the strainer. Clean the strainer and flush the tool out with gum solvent oil or an equal mixture of SAE No: 10 oil and
paraffin.
Allow the tool and strainer to dry then lubricate before use.
For a full service, contact your local Sealey service agent.
When not in use, disconnect the tool from the air supply, clean the tool and store the tool in a safe, childproof, location.
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.
