3.1 Air Supply
WARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the
die grinder. 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.
Recommended hook-up procedure is shown in fig 1.
3.1.1 Ensure die grinder air valve (or trigger) is in "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 Drain the air tank daily. Water in the air line will damage the die grinder.
3.1.4 Clean air inlet filter weekly.
3.1.5 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.
3.1.6 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 die
grinder. To overcome this, connect a leader hose to the grinder. A quick change coupling
may then be used to connect the leader hose to the air line recoil hose. See figs 1 & 2.

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): ................. 2.37m/s²
Uncertainty value (k):................................. 0.44m/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.
