PRO-SPOTTER AIR SYSTEM
TICO Manufacturing
Service Manual 8-3
Pressure Buildup, Low-Pressure
Warning Cutoff, and Governor Cutout
Test
1. Open reservoir drain valves and drain system.
2. Start engine and run at fast idle. Low-pressure
warning should be active.
3. Begin timing pressure buildup when system pressure
reaches 345 kPa/3.45 bar (50 psi). Record the
following data;
— The pressure at which low-pressure warning cuts
off.
— The time at which system pressure has reached
621kPa/6.21 bar (90 psi). Elapsed time should
not exceed specification.
—
4. Continue observing gauge. The governor cutout
should limit system air pressure to specification.

Removal
See Figure 8-1.
1. Park and prepare tractor for service. (See “Park
Tractor Safely” on page 1-3.)

CAUTION
2. Release air system pressure. (See “RELIEVING AIR

caps and plugs.
4. Install identification tags and disconnect electrical
connector (4).
5. Remove band (5).
6. Remove cap screws (6), washers (7), lock nuts (8),
and air dryer (9).
7. Repair or replace components as necessary.

• Avoid personal injury from explosion. Air
system components may contain pressurized
gases. Exposure to excessive heat may
cause components to explode.
• Avoid personal injury from high-pressure
gases or debris. High-pressure release of
gases or debris from a pressurized system
can cause penetrating injuries. Relieve
system pressure from air system before
servicing.
