MAINTENANCE
ROUTINE MAINTENANCE
This section refers to the various components which require
periodic maintenance and replacement.
It should be noted that the intervals between service requirements
may be significantly reduced as a consequence of poor operating
environment. This would include effects of atmospheric contamination
and extremes of temperature.
The SE R VICE/MAINTENANCE
components' descriptions and the intervals when maintenance has to
take place. Oil capacities, etc., can be found in the GENERAL
INFORM ATION section of this manual.
Compressed air can be dangerous if incorrectly handled. Before
doing any work on the unit, ensure that all pressure is vented from the
system and that the machine cannot be started accidentally.
CAUTION: Before beginning any work on the compressor, open,
lock and tag the main electrical disconnect and close the isolation
valve on the compressor discharge. Vent pressure from the unit
by slowly unscrewing the coolant fill cap one turn. Unscrewing
the fill cap opens a vent hole, drilled in the cap, allowing pressure
to release to atmosphere. Do not remove the fill cap until all
pressure has vented from the unit. Also vent piping by slightly
opening the drain valve. When opening the drain valve or the
coolant fill cap, stand clear of the valve discharge and wear
appropriate eye protection.
Ensure that maintenance personnel are properly trained,
competent and have read the Maintenance Manuals.
Prior to attempting any maintenance work, ensure that:–
. all air pressure is fully discharged and isolated from the system. If
the automatic blowdown valve is used for this purpose, then allow
enough time for it to complete the operation.
. the machine cannot be started accidently or otherwise.
. all residual electrical power sources (mains and battery) are
isolated.
Prior to opening or removing panels or covers to work inside
a machine, ensure that:–
. anyone entering the machine is aware of the reduced level of
protection and the additional hazards, including hot surfaces and
intermittently moving parts.
. the machine cannot be started accidently or otherwise.
Prior to attempting any maintenance work on a running
machine, ensure that:–
DANGER
Only properly trained and competent persons should
undertake any maintanence tasks with the compressor running or
with electrical power connected.
. the work carried out is limited to only those tasks which require the
machine to run.
. the work carried out with safety protection devices disabled or
removed is limited to only those tasks which require the machine to be
running with safety protection devices disabled or removed.
