XK12 Installation, Operating & Maintenance Manual
4.5 Driver Operating Instructions
The input speed should be between 1000 and 1600 rpm (1810 and 2896 rpm for high
speed machine) and the maximum pressure should not exceed 2.5 bar gauge.
Where the operator will be subjected to prolonged exposure to noise, it is
recommended that ear protection is provided.
To prevent high shaft torque and material blow-back, the XK12 should never be
started directly against a pressurised tank. Mid-delivery re-starting should only be
undertaken direct to atmosphere by fi tting a valve from discharge line (prior to the
check valve). When the compressor reaches operating speed, the line can be slowly
closed again to restart delivery.
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 XK12 is producing air.
• Set the engine speed to give a compressor operating speed
between 1000 rpm and 1600 rpm as required, (1810 and 2896 rpm for high
speed machine).
Stopping the compressor
• Return the engine speed to tick over
• Disengage the PTO.
• Stop the engine.
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.
