Operation & Maintenance Manual MAINTENANCE
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 air lines are nylon tubing. The associated f ttings 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 The tubing can be withdrawn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 f tting. 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 f rst 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 1/4 inch O.D. tubing. This will ensure that tubing
is fully engaged in the sealing mechanism.
