NOTICE
Piping systems operating at less than 150 psi
(1050 kPa) may use a special nylon tubing. The
associated fittings are also of a special “push-in”
design. If so, 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 The tubing can be withdrawn only while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 button. 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 the tubing is fully
engaged in the sealing mechanism.
NOTICE
The oil filters must be replaced every 500 hours of
operation or three (3) months, whichever comes
first. On new or overhauled units, replace the
element after the first 50 and 150 hours of
operation; thereafter, service the oil filters every
500 hours.
To service the 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:
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 filter element
counterclockwise to remove it from the filter
housing. Insect the filter.
NOTICE
If there is any indication of formation of varnishes,
shellacs or lacquers on the oil filter element, it is a
warning the compressor lubricating oil has
improper
characteristics and should be
immediately changed.
3. Inspect the oil filter head to be sure the
gasket was removed with the oil filter element.
Clean the gasket seal area on the oil filter head.
NOTICE
Installing a new oil filter element when the old
gasket remains on the filter head will cause an oil
leak and can cause property damage.
4. Lubricate the new filter gasket with the same
oil being used in the machine.
5. Install new filter by turning element clockwise
until gasket makes initial contact. Tighten an
additional ½ to ¾ turn.
6. Start unit and allow to build up to rated
pressure. Check for leaks before placing unit
back into service.
FASTENERS
Visually check entire unit in regard to bolts, nuts and
screws being properly secured. Spot check several
capsrews and nuts for proper torque. If any are found
loose, a more thorough inspection must be made.
Take corrective action.
COMPRESSOR OIL
The lubricating and cooling oil must be replaced every
1000 hours of operation or six (6) months, whichever
comes first.
