If the compressor is equipped with an automatic start-stop
control (with pressure switch unloading), it is automatically
unloaded upon starting, and will automatically load after
attaining running speed. If the compressor is equipped with
a constant speed control (pilot valve unloading), it is
necessary to manually unload the compressor, if there is
pressure in the discharge line, in order to achieve an
unloaded start. The compressor must be manually loaded
after the compressor has attained full running speed, there
after, it functions automatically to maintain operating
pressure until the unit is shut off.
Close the disconnect switch and start the compressor.
Observe the direction of rotation, which should be
counterclockwise when viewed from the flywheel side of the
compressor on all models. For single-phase units, the
direction of rotation is determined by the motor nameplate
instructions, and is adjusted at the factory. For three-phase
units, if the rotation is incorrect, stop the unit and
interchange any two of the three wires to the motor at the
disconnect switch. This will reverse the direction of rotation
of the motor and compressor.
PREVENTIVE MAINTENANCE
A good maintenance program will add years of service to your air
compressor. The following is recommended as a minimum
maintenance program. (TURN OFF POWER BEFORE
SERVICING.)
LUBRICATION
1. For proper lubrication the compressor shall not be
operated below the minimum or above the maximum R. P.M.
recommended for the various models.
2. Maintain oil level mid-way between the upper and lower lines
of the crankcase sight gage. NOTE ILLUSTRATION:
3. Stop compressor to add and gauge oil.
4. Do not fill above the upper line and do not operate compressor
with oil level below the lower line.
DO NOT OVER FILL
5. Change oil at the first 100 hours of operation and 1000 hours
thereafter, or as required. It may be necessary to change oil
more frequent due to abnormal humid and contaminated
conditions.
DAILY MAINTENANCE
1. Check and maintain oil level at centerline of sight glass and
add oil as necessary.
2. Drain condensate from receiver unless it is equipped with an
automatic tank drain, in which case the drain should be
checked weekly to see that it is operating. See automatic tank
drain instructions.
3. Check for unusual noise or vibration (See "Trouble Shooting".)
WEEKLY MAINTENANCE
1. Clean the air filters. A clogged air filter can seriously affect the
efficiency of the compressor and cause overheating and oil
usage.
2. Clean all external parts of the compressor and driver. Be sure
to clean the intercooler-finned surface on two-stage
compressors. A dirty compressor will cause abnormally high
discharge temperature and resulting oil carbonization on
internal valve components
3. Check the safety valve manually (by pulling ring or lever) to
see that it is not stuck.
MONTHLY MAINTENANCE
1. Inspect the entire air system for leaks.
2. lnspect condition of oil and change if necessary.
3. Check drive belt tension and tighten if needed.
EVERY 3 MOS. OR 1,000 HRS. OF OPERATION
1. Change oil.
2. lnspect valves. Clean the carbon from valves and head if
necessary.
3. Check and tighten if necessary all bolts, nuts, etc.
4. Check unloader operation.
*CHECKING BELT TENSION
The v-belt(s) should be adjusted so that a declination of about 3/8
– 1/2 inch will be obtained when it is pushed by a finger at the
middle point as shown in Figure 1.
CAUTION: Over tightening the v-belt(s) will result in
overloading of the motor and belt failure, while a loose belt
will be slipping and resulting in an unstable speed,
overheating the belt and high amp draw.
WARNING: Read and understand supplement LV-474 before installing and operating the compressor.
