Initial Operation and Maintenance
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 EP-80-90 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 BEARINGS:
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?
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 should stand up with no side wall buckling or distress as the tire rolls.
