4.1.5.
Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should
4.1.6.
be 1/2" internal diameter and fittings must have compatible inside dimensions.
4.1.7.
Keep hose away from heat, oil and sharp edges. Check hose for wear and make certain that all connections are secure.
COUPLINGS
4.2.
4.2.1.
Vibration may cause failure if a quick change coupling is connected directly to the wrench.
4.2.2.
To overcome this, connect a leader hose to the wrench (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. See fig.1 & fig.2.
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.
5.2.
Connect the wrench to the air hose as in Section 3.
5.3.
Place the socket over the subject nut and depress the trigger to operate the wrench.
5.4.
To change drive direction turn the direction control lever to the desired direction (fig.3).
DO NOT change direction whilst the wrench is running.
8
5.5.
The speed may be adjusted in forward or reverse gear by adjusting the speed control (fig.3). There are three speed settings in both
forward and reverse. DO NOT adjust speed whilst the wrench is running.
DO NOT use any additional force upon the wrench in order to remove a nut.
8
DO NOT allow wrench to free run for an extended period of time as this will shorten its life.
8
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. MAINTENANCE
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.
Clean the wrench after use. DO NOT use worn, or damaged sockets.
6.2.
6.3.
Loss of power or erratic action may be due to the following:
6.3.1.
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.
6.3.2.
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 and then lubricate before use.
6.4.
For a full service, contact your local Sealey service agent.
6.5.
When not in use, disconnect from air supply, clean wrench and store in a safe, dry, childproof location.
6.6.
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): 14.5 m/s²
Uncertainty value (k): 1.92m/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.
