Stabil-TRAK System Test
IMPORTANT: The operator must know that the Stabil-
TRAK system is active and functioning properly.
To test the function of the Stabil-TRAK system, read the
Stabil-TRAK system test instructions and follow steps 1
through 9 of the Stabil-TRAK system test procedure.
Stabil-TRAK System Test Instructions
• Test the Stabil-TRAK system with the vehicle on a
level surface.
• Remove any attachment from the quick attach
before performing the test.
• Perform the test with the boom fully retracted. DO
NOT extend the boom at any time during the test.
• DO NOT raise the boom above 60° for steps 3
through 6.
• DO NOT raise the boom above 45° for steps 7
through 9.
• Follow steps 1 through 9 of the Stabil-TRAK system
test procedure exactly as written.
IMPORTANT: If the Stabil-TRAK light goes OFF and the
front left tire lowers to the ground at any time during steps
4 through 7, the test was not performed properly or the
Stabil-TRAK system is not functioning properly. Carefully
repeat the steps starting with step 1. If the Stabil-TRAK
light goes OFF and the front left tire lowers to the ground
consistently during steps 4 through 7, the Stabil-TRAK
system is not functioning properly and the test should be
stopped immediately. DO NOT use the vehicle if the Sta-
bil-TRAK system is not functioning properly. Repair the
system immediately.
Stabil-TRAK System Test Procedures
1. Fasten seat belt and place the vehicle on a level
surface with 0° sway, no load on the forks, boom fully
retracted and horizontal. Check to be sure the Stabil-
TRAK light is OFF. See Fig. 10– 47 on page 10-48 for
the location of the light in the display panel.
2. Locate an 8 inch (203,2 cm) wood or cement block in
front of the left front tire and drive the vehicle up on
the block. Use the frame sway control to level the
vehicle back to 0° .
3. With the service brake pedal depressed, the parking
brake switch OFF, move the travel select lever to the
NEUTRAL (N) position and raise the boom to exactly
60° . The Stabil-TRAK light should come ON when
the boom angle is at about 40° and remain ON.
IMPORTANT: Perform steps 4 through 9 with the engine
rpm at idle.
4. While the service brake pedal is depressed, move
the travel select lever to the REVERSE (R) position.
Ease your foot off the service brake pedal and
increase the engine RPM slightly if necessary just
enough to back the vehicle off the block, while
keeping the service brake pedal partially depressed
so the Stabil-TRAK light remains ON. The rear axle
should remain locked while backing off the block and
the left front tire should remain off the ground.
5. While keeping the service brake pedal depressed,
move the travel select lever to the NEUTRAL (N)
position and take your foot off the service brake
pedal. The rear axle should remain locked, the Stabil-
TRAK light should remain ON, and the left front tire
should remain off the ground.
6. With the travel select lever in the NEUTRAL (N)
position, engage the parking brake switch and move
the travel select lever to the FORWARD position. The
rear axle should remain locked, the Stabil-TRAK light
should remain ON, and the left front tire should
remain off the ground.
7. With the parking brake switch ON, move the travel
select lever to the NEUTRAL (N) position, and lower
the boom to exactly 45° . Use the frame sway control
to tilt the vehicle no more than 5° to the left and then
no more than 5° to the right. The vehicle should sway
slowly to the left and then to the right. The Stabil-
TRAK light should remain ON, and the left front tire
should remain off the ground. The left front tire
should not raise or lower when swaying. Leave the
vehicle swayed to the right 1° to 2° .
DANGER: Vehicle tipover can result in death
or serious injury. DO NOT use the vehicle if the
Stabil-TRAK system is not functioning properly.
WARNING: DO NOT operate this vehicle
unless you are in the seat with the seat belt fas-
tened around you. Death or serious injury could
result if the belt is not securely fastened.
