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. Do Not Exceed
