Product Manual

2.7
General functional description
 Before switching on the compressor ensure that proper
earthing is done as per recommendation.
 Make all adjustments or repairs with one hand. This
minimizes the risk of creating a current path through
the heart.
 Conduct repairs only in a clean, dry, well-lit and
ventilated area.
 Do not leave the compressor unattended with open
electrical enclosures. If necessary to do so, disconnect
the power to the compressor at the source and lock it
out so that power is not in advertently restored.
 Disconnect, lock out, and tag the power source prior to
attempting repairs or adjustments, turning the
compressor manually or handling ungrounded
conductors.
 All electrical installation must be in accordance with
recognized electrical codes and any local health & safety
codes.
 Recognize that only authorized and qualified trained
personnel should carry out any electrical work on the
compressor.
 Regularly check that all electrical connections are tight
and in good condition.
Periodically check whether
 All guards are in place and securely fastened.
 All hoses and pipes inside the compressor are in good
condition, secure and not rubbing against each other.
 Any leaks exists.
 All fasteners are tight.
 All electrical leads are secure and in good order.
 Safety valves and other pressure relief devices are not
obstructed by dirt or paint.
 Air outlet valve, i.e. pipes, couplings, manifolds, valves,
hoses, etc. are in good repair, free of wear or abuse.
 The air-oil tank is properly grounded.
2.3.3 Precautions during maintenance
 Use safety glasses and incorporate safe working
practices before maintenance work.
 Use appropriate tools for all maintenance works.
 Use only genuine spare parts. Refer the section “Use
genuine spare parts” in “Maintenance” chapter.
 Ensure that the compressor is cooled down before
maintenance is performed.
 Springs under tension or compression store energy.
Uncontrolled release of this energy can cause serious
injury or death. Be cautious while performing the
maintenance of components loaded with springs (for
example minimum pressure valve, safety valve etc.).
 Display a warning sign that says “Maintenance under
progress, don’t switch on” near the start switch.
 Isolate the compressor from the air line (discharge) and
disconnect the power by opening and locking the
isolating switch before maintenance.
 Prior to attempting repairs or adjustments, disconnect
the power at the source and verify at the compressor
that the circuits have de-energized. This minimizes the
possibility of accidental start-up or operation, especially
when the compressor is remotely controlled.
 Open the oil filler cap only when the compressor is not
running and is not pressurized. Shut down the
compressor and bleed the receiver tank to zero internal
pressure before removing the cap.
