5-157 MISCELLANEOUS CONTROLS AND OPTIONS
Caution during operation
1) The engine clutch must be operated in sequence. If the clutch pedal is released instantaneously,
power is transmitted instantaneously to affect PTO, crank components, and rotating parts, result-
ing in damage to the related parts.
2) Do not increase or decrease compressor RPM using the accelerator pedal in the cab. When cleaning
or servicing the pipe or adjusting RPM after completing operation, if an abrupt change is given to
the related parts, damage to them may result.
3) Do not apply overload to the compressor when the engine RPM is at low idle at each pre-opera-
tion stage. Engine overload affects the engine adversely or causes resonance phenomenon. If this
situation occurs, first open the exhaust valve to discharge air and relieve overload.
4) Caution when stopping: If the compressor is stopped with pressure remaining in the tank, cement
in it enters the cylinder, causing various damage to the compressor.
5) If water enters the air breather on the crankcase when cleaning the compressor, lubricating func-
tionality is disabled.
6) Intake filter element: If the filter element is filled with dust, the amount of incoming air decreases
and also performance efficiency is reduced. Therefore, clean the filter element every month. If dust
settles inside the filter element, replace it. Generally as dust settles at the bottom of the filter case
around the inlet port, use a damp cloth in order to prevent the settlement of dust on the inlet
port. (Interval of replacement: every 250~500 hours(3~4 months)
How to operate the compressor
1) Depress the clutch pedal, press the PTO to "ON" position, and then slowly release the pedal to
operate the compressor. (When completing operation, depress the clutch slowly and press the
PTO switch to "OFF" position.)
2) Adjust the control lever to obtain proper RPM(800 RPM) for operating the compressor. Bring and
hold the lever to the gauge scale of 800 rpm.
Caution
Do not rotate the compressor at 750 rpm or less, or over 850 rpm, because it may be damaged.
