General; Daily Operation; Maintenance After Initial 50 Hours Of Operation; Maintenance Every 100 Hours - Sullair 900XH Operators Manual And Parts Lists

5.1 GENERAL

A good maintenance program is the key to long
compressor life. Below is a program that when
adhered to, should keep the compressor in top
operating condition. For engine maintenance
requirements, refer to the Engine Operator's
Manual for a detailed description of service instruc-
tions. See Parts Replacement and Adjustment
Procedures for a detailed description of specific
compressor system components. Prior to perform-
ing maintenance, read the CIMA Safety Manual, if
applicable.
DO NOT remove caps, plugs and/or
other components when compressor is
running or pressurized.
Stop compressor and relieve all inter-
nal pressure before doing so.
Stop compressor and relieve all internal pressure
before doing so.

5.2 DAILY OPERATION

Prior to starting the compressor, it is necessary to
check the fluid level in the sump. Should the level
be low, simply add the necessary amount. If the
addition of fluid becomes too frequent, a simple
problem has developed which is causing this
excessive loss. See the Troubleshooting Section
(5.11) under Excessive Fluid Consumption for a
probable cause and remedy. Also check the engine
oil level and the radiator coolant level prior to start-
ing.
The radiator and engine cooling sys-
tem must be drained and flushed every
two (2) years. Replace the coolant with
a solution of 50% ethylene glycol and
50% water or as required for your geo-
graphic location. DO NOT use a leak
sealing type of anti-freeze. Should a
100% water solution be used, a non-
chromate rust inhibitor must be added.
After a routine start has been made, observe the
instrument panel gauges and be sure they monitor
the correct readings for their particular phase of
operation. After the compressor has warmed up, it
is recommended that a general check on the over-
all compressor and instrument panel be made to
assure that the compressor is running properly.
WARNING
NOTE
Also check the air filter restriction gauges. Should
they indicate restriction, replace the elements
immediately (see Air Filter Maintenance in Section
5.10).
5.3 MAINTENANCE AFTER INITIAL 50 HOURS OF
OPERATION
After the initial 50 hours of operation, a few simple
maintenance routines can rid the system of any
possible foreign materials, if any. Perform the fol-
lowing maintenance operations to prevent unnec-
essary problems.
1. Clean the return line orifice and strainer.
2. Change compressor fluid filter.
3. Check Engine Operator's Manual for required
service.

5.4 MAINTENANCE EVERY 100 HOURS

After 100 hours of operation, it will be necessary to
perform the following:
1. Check the battery level and fill with water if nec-
essary.

5.5 MAINTENANCE EVERY 250 HOURS

Perform the following after every 250 hours of oper-
ation:
1. Check fan belt tension.
2. Clean the radiator and cooler exterior. Depending
on how contaminated the atmosphere may be,
more frequent cooler and radiator cleaning may
be necessary. To clean between fluid cooler and
radiator, the three (3) bolts securing the top of
the fluid cooler to the top mounting bracket
should be removed, allowing the fluid cooler to
swing down on its lower hinge. This will allow
easier access to clean between the fluid cooler
and radiator cores.
3. Check Engine Operator's Manual for required
service.
4. Change the engine oil and oil filter. This is best
done when the engine is hot.

5.6 MAINTENANCE EVERY 300 HOURS

When using fluids other than Sullair AWF, change
the compressor fluid and replace the fluid filter ele-
ment (See maintenance procedure in Section 5.10).

5.7 MAINTENANCE EVERY 500 HOURS

When using Sullair AWF, replace the fluid filter ele-
ment and change compressor fluid. (See mainte-
nance procedures in Section 5.10).

5.8 MAINTENANCE EVERY 1000 HOURS

Perform the following after every 1000 hours of
operation:
