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 56). 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 56).
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 57).
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.
