TICO Manufacturing
AIR SYSTEM PRO-SPOTTER
INTRODUCTION
The purpose of the AIR SYSTEM section is to provide
service and maintenance personnel with guidance on the
proper procedures for servicing pneumatic equipment on
TICO Pro-Spotter terminal trucks. The air system is
made up of an air compressor, air dryer, and air tanks,
which supply air pressure to pneumatic subsystems
including brakes, cab and seat suspension, and trailer
connections.
The TICO Pro-Spotter terminal trucks have been
engineered for quick and efficient servicing while
minimizing downtime.
For additional information, please contact TICO factory
support. (See “CONTACT TICO SUPPORT” on
page 0-15.)
AIR BRAKE SYSTEM TESTS
The following air brake system tests should be performed
periodically to determine the condition of the system.
These tests are designed to help discover sluggish
performance and/or system leaks before they become a
major problem. Performing these tests does NOT rule out
the importance and necessity of functional, dynamic
controllability tests and other tests required in assuring
vehicle safety and performance.
Low Air Buzzer and Light Test
1. Apply and release the brake pedal until air pressure
drops below specification.
2. The low air buzzer and dash warning light should
come on.
Air System Maximum Pressure Test
1. Start engine and run at fast idle.
2. Monitor air pressure gauge.
3. Governor cutout should limit system air pressure to
specification.
Air System Leak Down Test
1. Disconnect the glad hands from the trailer.
2. Run engine at fast idle.
3. Allow air pressure to stabilize at operating pressure
for at least 1 minute.
4.
5. Shut off engine and observe pressure gauge for 2
minutes.
6. Pressure drop should not exceed specification.
