Refer to Figure 7-2. Maintenance should be performed
when indicated by the controller. Both air filters are two-

3. Remove the primary filter from the housing.
4. Clean the interior of the housing by using a
damp cloth. Do not blow out dirt with com-

stream of the filter.

Control system adjustment

Refer to Figure 7-3. Prior to adjusting the control system,
it is necessary to determine the desired operating pres-
sure range as well as the maximum pressure at which
the machine is to operate. This pressure is stamped on
the machine serial number plate.
Follow the procedure below for setting up the pressure
regulator.
1. Start the machine and let it warm-up and
press the LOAD button.
2. Open service valve slightly until engine tries
to speed up, then slowly close the service
valve.
3. With service valve closed and the engine at
low idle (1400 rpm), adjust the pressure reg-
ulator until the service pressure is approxi-
mately 20 – 25 psi (1.4 – 1.7 bar) above the
desired operating pressure.
• For example, if the desired service pressure
is 150 psig (10.3 bar), the regulator should
be adjusted to 170 – 175 psig (11.7 –
12.1 bar) at 1400 rpm. Open the service
valve to load the compressor to maintain
150 psig (10.3 bar) or desired discharge
pressure. Operating speed should be
1800 rpm on the instrument panel. If not,
repeat step, but adjust the unload service
pressure up or down as needed until
150 psig (10.3 bar) is maintained when
engine speed is 1800 rpm.
