SAFETY RULES ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide safe equipment can be erased by an operator’s single careless act. In addition, hazard control and accident prevention are dependent upon the awareness, concern, judgement, and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.

INITIAL OPERATION/MAINTENANCE 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? IMPORTANT: Has the slip clutch on the PTO been serviced? If the slip clutch is left unchecked, damage to the power-take-off and drive shaft may result.

Preparing the Grain Cart for Use (see tractor recommendation for grain cart model below): Model 750-16 or 750-18 Grain Cart requires a 130 hp tractor or larger. IMPORTANT: Do NOT pull loaded grain cart on highway. For incidental highway travel, observe the section below.
Page 12
LOADING AND UNLOADING THE GRAIN CART 1) With the gate indicator in the closed position, fill the tank with grain. 2) With the PTO disengaged, fold discharge auger to upright position. 3) IMPORTANT: After the auger is in the upright position, be sure to start the PTO at a SLOW RATE OF SPEED until the lugs on the upper auger engage the drive dog on the bottom auger (failure to follow this procedure may cause extensive damage to both the drive dog and drive line.) 4) Increase PTO speed and open the inner gate until the pointer is in the half-way position.
LUBRICATION SERVICE SCHEDULE IMPORTANT: Your Grain Cart has grease fittings at all critical points. These should be serviced before the cart is put into operation.

ADJUSTING THE SLIP CLUTCH After the first hour of operation, the slip-disc clutch should be checked for overheating. After this first check, the slip-disc clutch should be checked weekly or anytime there is excessive slippage of the friction discs. The slip-disc clutch should be checked for moisture, which could cause corrosion on the drive plates. If the grain cart has been idle for an extended period of time, or in wet weather, check to make sure that the friction lining plates are not rusted or corroded together.
ADJUSTING THE UPPER FLIGHTING MAKE SURE THAT ALL POWER IS SHUT OFF BEFORE ADJUSTING THE FLIGHTING ASSEMBLY. If the upper and lower flightings do not properly separate during the unfolding sequence, the upper flighting may need adjusting. Before making adjustment to upper flighting, check to see if the lugs and drive-dog are locking together (If not, dirt in the restricter or a faulty check valve on the hydraulic cylinder that is used to raise the upper tube may be the cause of the problem.
