Maintenance
5.1 General
Consistent and correctly performed maintenance will
ensure the compressor’s performance and extend its
operational life. See Section 5.9: Part replacement and
adjustment procedures on
page 5
1 for a detailed descrip-
tion of specific compressor component
s. Before perform-
ing maintenance actions, read the CIMA Sa
fety Manual,
if applicable. For engine maintenance requirements and
procedures, refer to the Engine Operator’s Manual.
5.2 Daily operation
Prior to starting the compressor, it is necessary to per-
form a daily inspection. Perform the following mainte-
nance operations to prevent unnecessary problems.
• Check the fluid level in the compressor receiver
tank. Should the le
vel 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.
Refer to Table 5-2: Troubleshooting guide on
page 57 under “Excessive Compressor Fluid
Consumption” for a probable cause and remedy.
• Drain water from the fuel/water separator.
• Check the fuel level in the fuel tank.
• Check the engine oil level.
• Check the engine coolant level.
• Check the engine DEF level.
• Check the air filter restriction gauges. Should
they indicate restriction, replace the elements
immediately. Refer to Section 5.9.3: Air filter
maintenance on page 52.
After a routine start has been made, it is necessary to
pe
rform an
inspection to ensure all operations are per-
forming correctly. Perform the following inspections to
pr
event unnecessary problems.
• 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 rec-
ommended that a general check on the overall
compressor and instrument panel be made to
assure that the compressor is running properly.
5.3 Engine coolant requirements
This machine is factory filled with Mobil Delvac Extended
Life Coolant. It is an ethylene glycol based, OAT inhibited
coolant. This coolant is able to protect the cooling system
from freezing, extend the boiling point, provide corrosion
protection for all metals within the cooling system; espe-
cially for systems with aluminum radiators, provide liner
cavit
ation
protection for heavy duty diesel engines, and
be safe to use with all seals/gasket materials.
This coolant should never be mixed with a different cool-
ant type, color, or brand. If radiator coolant is to be
added, for
any reason, be sure that the coolant added is
the same as what is in the cooling system, as well as
what is recommended.
WARNING
Do not remove caps, plugs and/or other compo-
nents when the compressor is running or pres-
surized. Stop the compressor and relieve all
internal pressure
by following proper lockout/
tagout procedures before removing these items.
WARNING
Failure to follow the coolant requirements may
cause cooling system inefficiencies which may
result in the engine overheating. Using a coolant
other than those recommended can drastically
reduce the life expectancy of the cooling circuit
and the engine.
