Operating & Maintenance Manual
Radiator
The use of water alone in this engine
can result in major engine failure.
Refer to engine section for coolant
recommendation.
Hoses
Each month it is recommended that all of the
intake lines to and from the air cleaners, the
engine cooling system hoses and all of the
flexible hoses used for air, oil, and fuel be
inspected.
To ensure freedom from air leaks, all rubber
hose joints and the screw-type hose clamps
must be absolutely tight. Regular inspection
of these connections for wear or deterioration
is necessary.
Premature wear of both the engine and
compressor is ASSURED whenever dust-
laden air is permitted to enter the engine's
combustion chamber or compressor intake.
The flexible hoses used in the fuel, oil and air
lines on these units are primarily used for
their ability to accommodate relative
movement between components. It is
important they be periodically inspected for
wear and deterioration. It is also important
the operator does not use the hoses as
convenient hand hold or steps. Such use can
cause early cover wear and hose failure.
Some of the airlines are nylon tubing.
The associated fittings are "push-in"

design. Features are as follows:
Pulling on the tubing will cause the inner
sleeve to withdraw and compress, thus
tightening the connection. The tubing can be
withdrawn only while holding the sleeve
against the fitting. The tubing can be
removed and replaced numerous times
without losing its sealing ability.
To install the nylon tubing, make a mark (with
tape or grease pencil) approximately 7/8 inch
from the end of the tubing. Insert the tubing
into the sleeve and "push-in" past the first
resistance to the bottom. The mark should be
approximately 1/16 inch from the sleeve, for
the 3/8 inch O.D. tubing; 1/8 inch for the 0.25
inch O.D. tubing. This will ensure that tubing
is fully engaged in the sealing mechanism.
Compressor Oil Filters
The oil filter must be replaced every 500
hours of operation or six (6) months,
whichever comes first.
To service oil filters it will first be necessary
to shut the unit down. Wipe off any external
dirt and oil from the exterior of the filter to
minimize any contamination from entering
the lubrication system. Proceed as follows:
!
WARNING
High pressure air can cause severe
injury or death from hot oil and flying
parts. Always relieve pressure before
removing caps, plugs, covers or other
parts from pressurized air system.
1. Open the service air valve(s) to ensure
that system is relieved of all pressure.
Close the valve(s).
2. Turn
the
spin-on
counterclockwise to remove it from the
filter housing. Inspect the filter.
