Guidelines for Regular Maintenance (continued)
Wheel/Tire Maintenance
•
Once a month, check the wheel lug bolt torque. The recommended torque is 120 ft. lbs.
•
Check the tires and maintain proper tire pressure:
•
28-30 PSI for Ag Rib Tires
•
64-66 PSI for Truck Tires
•
12-15 PSI for Turf Tires
ATTENTION:
When storing the spreader for a period of time, block up the spreader to remove
weight from the tires. Doing so helps to prevent any possible damage to the tires.
Wheel Bearing Maintenance
•
Adjust the wheel hub bearings after 100 loads and once each season thereafter.
•
Use a jack to raise the spreader to remove weight from the wheel.
CAUTION:
Be sure to block up the spreader to prevent personal injury while
working on the wheels.
•
Rotate the wheel and torque the wheel hub bearings to 25 ft. lbs.
•
Back off the nut one flat, plus enough to install the cotter pin (1/6 turn min.,
1/3 turn max.)
Hydraulic System Maintenance
•
Periodically check the condition of the hydraulic hoses for flexibility and any signs of
rubbing/weakness on the outer surface. Replace the hose(s) as soon as any weakness or
cracking is noted.
•
Proper oil maintenance for Tractor Driven Hydraulic Units:
The Tractor Hydraulic unit is
shipped with Universal Tractor Hydraulic Fluid (UTF) in the lines. To protect your tractor,
make sure the UTF supplied with the spreader is compatible with the oil in your tractor.
•
Proper oil maintenance for PTO Hydraulic Units:
The PTO Hydraulic unit is supplied with
an ISO Grade 46 hydraulic oil in the reservoir. (Specifications for the oil are shown below.)

Replace the oil filter
after the first 10 hours of operation. After that initial period, replace the filter
every 100 hours (in dusty conditions) or every year.
-
Periodically check the oil level
, which can be viewed through the sight gauge mounted on the
front of the oil reservoir. NEVER allow the oil to run below the level visible through the sight gauge.
