MAINTENANCE (Continued)
c. Apply pressure with finger to one belt
at midpoint span. Tension is correct if belt
can be depressed
3/8 to 1/2". Make further adjustments if
necessary.
d. Check the alignment of pulleys.
Adjust if necessary.
e. Tighten mounting hardware to secure
motor on base.
f. Re-install guard and secure
with bolts.
Never operate unit
without belt guard in place. Removal will
expose rotating parts which can cause
injury or equipment damage.
EVERY 90 DAYS OR 500 HOURS
1. Change crankcase oil. Use type
grade oil as specified in the
section on "Compressor Oil
Specifications
2. Check entire system for air leakage
around fittings, connections, and
gaskets, using soap solution and
brush.
3. Tighten nuts and capscrews
as required.
4. Check and clean compressor
valves, as required. Replace parts
when worn or damaged.
Valves must be
replaced in original position. Valve gaskets
should be re-placed each time valves are
serviced.
5. Pull ring on all pressure relief valves
to assure proper operation.
GENERAL MAINTENANCE NOTES
BELTS
Drive belts must be kept tight enough to
prevent slipping. If belts slip or squeak,
see V-belt maintenance in preceding
section.
If belts are too tight,
overload will be put on motor and motor
bearings.
COMPRESSOR VALVES
If compressor fails to pump air or seems
slow in filling up tank, disconnect unit
from power source, remove valves, and
clean thoroughly, using compressed air
or a soft wire brush. After cleaning,
exceptional care must be taken that all
parts are replaced in exactly the same
position and all joints must be tight or the
compressor will not function properly.
When all valves are replaced and
connections tight, close hand valve at tank
outlet for final test. Valve gaskets should
be replaced each time valves are removed
from pump.
CENTRIFUGAL UNLOADER AND
PRESSURE RELEASE VALVE
The centrifugal unloader is operated by
two governor weights. It is totally enclosed
and lubricated from the crankcase of the
compressor. When compressor starts the
governor weights automatically open
compressing the main spring, allowing the
unloader release valve to close. When the
compressor stops, the main spring returns
the governor weights to normal position
and opening the pressure release valve and
unloading the compressor.
This prevents overloading the motor when
starting. If air continues to escape through
the governor or unloader pressure release
valve while operating, this is an indication
that the release valve is not closing tightly
and may be held open by foreign
substance which has lodged on the seat. In
order to correct this, remove the governor
release valve cap, giving access to release
valve spring and ball. Clean thoroughly and
return parts in the same order in which
they were removed.
Loose drive belts can also cause unloader
to leak by preventing the compressor from
reaching proper speed. (See "BELTS"
above.)
LUBRICATION OF COMPRESSOR
Fill crankcase to proper level as indicated
by oil sight gauge. Keep crankcase filled as
required by usage.
AIR COMPRESSOR OIL
SPECIFICATIONS
Compressors are factory filled with
CHAMPLUB hydrocarbon based recip
lubricant.
This is an ISO 100 non-detergent industrial
lubricant with rust and oxidation inhibitors
specially formulated for reciprocating
compressors. It is recommended this
compressor be maintained using this oil
for ambient temperatures above 32°F.
CHAMPLUB synthetic is a premium grade
diester based synthetic lubricant providing
excellent performance in high temperature
applications.

Do not mix oil types,
weights or brands.
"Emulsification of
oil (white milky substance) indicates
unsafe accumulation of moisture and
may be evidence compressor is
oversized for application. Failure to
promptly consult your local
distributor, or Champion Customer
Service, can be grounds to deny
warranty."
NOTES:
1. Normal break-in period of
Champion air compressors is 25
hours.
2. For the first 100 hours of
compressor operation, a careful
and regular check of the oil level
should be made. Maintain oil level
at the full line.
CHANGING TO SYNTHETIC LUBRICANT
(Applies to diester based synthetic
lubricant only).
If changing to synthetic lubricant, the
following steps must be completed.
1.
Compressor must run for a 25 hour
break-in period using
ChampLub ISO 100 oil.
2.
Thoroughly drain existing oil from
crankcase.
3.
Fill crankcase with a full charge of
synthetic lubricant.
4.
Run compressor for 200 hours.
5.
Stop compressor and thoroughly
drain the synthetic lubricant.
6.
Add a full charge of synthetic
lubricant.
7.
Compressor now ready to run for
extended period before next
lubricant change.
