WARNING
BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING THE GRAIN CART.
Before the grain cart is put into service:
•
Have the safety instructions been read and clearly understood by the operator(s) of this machine?
•
Has the gearbox been properly filled with SAE 80W-90 gearbox lubricant?
•
Have all nuts, bolts, bearings and braces been properly fastened?
•
Has the PTO been checked for proper overlap?
IMPORTANT: Has the slip clutch on the PTO been serviced? If the slip clutch is left unchecked, damages to the power-take-off
and drive shaft may result. Before using the grain cart, loosen the bolts around the slip clutch. Make sure the friction plates turn
free of each other and are not corroded together. Re-tighten the tension bolts. Run the auger system EMPTY and check for proper
engagement of the slip clutch.
CHECK PTO OVERLAP LENGTH: Overlap length may vary depending on the tractor model and hitch setting. Try to obtain the greatest
possible overlap without bottoming out in the extreme operating conditions. Too much overlap may cause the PTO to bottom out
and damage the driveline. Not enough overlap may cause the PTO front and back halves to separate. From the fully compressed
(shortest) length the PTO should be telescoped (extended) between 10" and 22". Different PTO lengths may need to be purchased to
accommodate your terrain. A 4" shorter or a 10" longer PTO can be ordered through your dealer from J&M Manufacturing.
GREASE POINTS: Are all bearings on the drive line properly greased? Are all set screws in the bearings and U-joints tight? Has the
power-take-off shaft been properly greased at all points including the cross bearings? Has the universal joint at the gearbox been
greased? Have all grease points at the auger hinge area, including the hanger bushing assembly been greased? If applicable, has the
swivel ball hitch been greased?
TIRE PRESSURE: Are the tires properly inflated? The following is to be used as a general guide for tire inflation for cyclic use. Figures
can vary depending on specific brand of tire used. It is important that tires are inspected before and after the unit is loaded. The tire
pressures below are recommended by the manufacturer. On select tires the listed pressure is lower than the max tire pressure to
reduce compaction. If desired, the pressure MAY BE increased UP TO the max tire pressure for traveling long distance while
empty on the road.
