4.1. Air Supply
Recommended hook-up procedure is shown in fig.1.
4.1.1. Ensure die grinder air valve (or trigger) is in "off" position before connecting to the air supply.
4.1.2. You will require an air pressure of 90psi, and an air flow according to specification.
4.1.3. WARNING! Ensure the air supply is clean and does not exceed 90psi 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.
4.1.4. Drain the air tank daily. Water in the air line will damage the die grinder.
4.1.5. Clean air inlet filter weekly.
4.1.6. 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.
4.1.7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all
connections are secure.
4.2. 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 fig.1 & 2.

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): .........1.25m/s²
Uncertainty value (k):.........................∙061m/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.
