Inspecting the Wheels/Tires

Service Interval: Before each use or daily—Check the
tire pressure.
After the first 8 hours—Torque the
wheel lug nuts.
Every 100 hours—Torque the wheel
lug nuts.
Every 100 hours—Inspect the
condition and wear of the tires.
Check the tire pressure every 8 hours or daily to ensure
proper levels. Fill the tires to 18 psi (124 kPa). Also,
check the tires for wear or damage.
Check the wheels to ensure that they are mounted
securely after the first 8 operating hours and then
every 100 hours thereafter. Torque the front bolts
to 50-55 ft-lb (68-74 N-m) and the rear lug nuts to
40-60 ft-lb (54-81 N-m).
Check the tire condition at least every 100 hours
of operation. Operating accidents, such as hitting
curbs, can damage a tire or rim and also disrupt wheel
alignment, so inspect tire condition after an accident.
Adjusting the Front Wheel
Toe-In
Service Interval: Every 100 hours/Yearly (whichever
comes first)
The toe-in should be 0 to 1/4 inch (0 to 6 mm).
1. Fill the tank with approximately 80 US gallons
(303 L) of water.
2. Check and fill all tires; refer to Checking Tire
Pressure.
3. Drive the sprayer back and forth a few times to relax
the A-arms, then drive it forward at least 10 ft (3 m).
4. Measure the distance between both of the front tires
at the axle height at both the front and rear of the
front tires (Figure 58). A fixture or alignment gauge
is needed for the rear measurement of the front tires
at axle height. Use the same fixture or alignment
gauge to accurately measure the front of the front
tires at axle height (Figure 58).
The front of the tires should be 0 to 1/4 inch (0 to
6 mm) closer than the back side of the front tires.
1. Tire center line-back
2. Tire center line-front
3. Axle center line
5. If the measurement does not fall within the specified
range, loosen the jam nuts at both ends of the tie
rods (Figure 59).
1. Jam nut
6. Rotate both tie rods to move the front of the tire
inward or outward.
Note: The tie rods should be the same length when
you are finished.
7. Tighten the tie rod jam nuts when the adjustment is
correct.
8. Ensure that there is full travel of the steering wheel
in both directions.
