Compressor Adjustment If after performing the above checks and the air pressure is still
outside the recommended setting for your location, adjust the air
pressure by turning the screw as shown in figure D.
Altitude correction is needed above 7,000 feet (2134 m) (see figure C
on page 2).
If the air compressor pressure cannot
be adjusted back into normal range,
repair or replace air compressor.
Refer to parts manual.

Air Pressure Checks If air pressure is outside the recommended setting for your location
please perform the following checks before adjusting the compressor:
Low Pressure Reading – Check:
Ensure the coil voltage is nominally 12 ±1V for 12V models and 24 ±1V
for 24V models. If voltage is low, charge batteries and check compressor
reading again.
i) Inspect air line from compressor outlet to fan end inlet for leaks,
kinks or other restrictions.
ii) Check condition of air compressor filter. Retest with the filter
removed.
High Pressure Reading – Check:
Ensure the coil voltage is nominally 12 ±1V for 12V models and 24 ±1V
for 24V models. If voltage is high, stop charging batteries (turn engine
off) and check compressor reading again.
i) Nozzle and cavity for blockage. Refer to Step 5 on page 5-10 of
the X45 service manual.
