4.2. Drain the air tank daily. Water in the air line will damage the saw and will invalidate your warranty.
4.3. Clean compressor air inlet filter weekly.
4.4. 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.
4.5. Keep hose away from heat, oil and sharp edges. Check hoses for wear and make certain that all connections are secure.
4.6. Couplings Vibration may cause failure if a quick-change coupling is connected directly to the air saw. To overcome this, connect a
leader hose (Sealey Part No. AH2R) to the saw. A quick-change coupling may then be used to connect the leader hose to the air line
recoil hose. MAINTENANCE

5.1.6. If the cut ends within the sheet material allow the blade to come to a stop before removing the saw from the workpiece.
5.1.7. If the cut starts within the bounds of the material cut a starter slot by hand.
5.1.8. DO NOT allow the saw to run without load for any length of time as this will damage the bearings.
5.2. TO CHANGE THE BLADE

6. MAINTENANCE
WARNING! Disconnect saw from air supply before changing the blade, servicing or performing maintenance.
6.1. Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
6.2. Unless the air supply system includes an oiler, lubricate the air saw daily with a few drops of air tool oil, dripped into the air inlet
before use (use Sealey part no. ATO/500 or ATO1000).
6.3. 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 line. 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saw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 saw out with gum solvent oil or an equal mixture of SAE No 10 oil and kerosene.
Allow to dry before use.
If you continue to experience problems, contact your local Sealey service agent.

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): ........12.166 m/s²
Uncertainty value (k):...........................1.5 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HSEwebsite
