PREPARING WRENCH FOR USE

Air Supply
Recommended hook-up procedure.

• Ensure wrench air valve (or trigger) is in the “off” position (i.e. released) before connecting to the air supply.
• 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.
•  Drain the compressor air tank daily. Water in the air line will damage the wrench.
•  Clean air inlet filter weekly. 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.
• Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.

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.

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 a impact wrench.
  • DO NOT use worn or damaged sockets.
  •  Connect the wrench to the air hose.
  • Place the socket over the subject nut and depress the trigger to operate the wrench.
  • To change direction, push the button above the handle. Direction of “R” for reverse and F” for forward
  • The flow of air may be regulated by adjusting flow valve at the base of the handle.
• DO NOT use any additional force upon the wrench in order to loosen/tighten a fixing.
• DO NOT allow wrench to free run for an extended period of time as this will shorten bearing life.

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.

•  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.

• Check and top up the gearbox by removing grub screw located on the side of the body
  adjacent to the trigger.

•  Clean the wrench after use.

•  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 chapter 3.
  • 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.
  •  For a full service contact your local Sealey service agent.
  •  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 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):  5.78 m/s²
• Uncertainty value(k):  0.6468 m/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.
