TR20 Installation, Operating & Maintenance Manual
4.5
Driver Operating Instructions
The input speed should be between 900 and 1650 rpm and the maximum pressure
should not exceed 2.2 bar gauge.
To prevent high shaft torque and material blow-back, the TR20 should never be
started directly against a pressurised tank. Mid-delivery re-starting should only be
undertaken direct to atmosphere by opening the valve fitted in the discharge line
(prior to the check valve). When the compressor reaches operating speed, the valve
can be slowly closed again to restart delivery.
Inclination Angle
The maximum permitted inclination angle when operating the
TR20 is:
10
o
fore and aft
10
o
left to right
Pre-Start Procedure
• Check engine fuel level (if applicable).
• Check compressor oil level.
• Connet pressure lines.
• Check inlet filter has no blockages.
• Ensure tanker is not pressurised.
• Ensure pressure lines are open.
• If pressurised, open ball valve on the tanker.
Starting the compressor
• Check that the PTO is disengaged and then start the engine.
• Set the engine speed to tick over.
• Depress the clutch and allow a minimum of 5 seconds for the gears to stop
rotating.
• Engage the PTO.
• SLOWLY release the clutch.
• Check that the TR20 is producing air.
• Set the engine speed to give a compressor operating speed between 900 rpm
and 1650 rpm as required.
Commissioning
To avoid risk of burns, do
not touch pipework or stand
close to ventable valves
during discharge. If there is a
risk, suitably resistant gloves/
clothing must be used.
CAUTION
Do not operate compressor
against dead head or pressurised
tanker. This will result in
premature component or/and
system failure.
CAUTION
CAUTION
Where the operator will be
subjected to prolonged exposure
to noise, it is recommended that
ear protection is provided.
