Torque to 500 ft-lbs. IMPORTANT: When mounting for the first time, the front hook bolts will have to be tightened after positioning the hook directly over the mounting boss (most rearward position). 9. Raise the loader and lock the support stand tubes into the up position. NOTE: When mounting for the first time, raise the loader slowly and check to make sure that the hoses do not bind or become pinched in all positions. Work the loader and bucket up and down to work out all the air in the hydraulics. Check and refill the tractor's hydraulic system. 13 Removing the Loader from Your Tractor WARNING ! When removing the loader, it must be fitted with a bucket or other suitable attachment to give the frame stability after removal. If this is not done, the frame will not remain standing. " " ' ------------------------I IMPORTANT ! Always remove the loader on firm, level ground (away from children's play areas and high traffic areas). This makes attaching and removing much faster and easier. It also makes the free standing loader more stable. 1. Raise the loader, lower support stand tubes and i lock into position. ’ 2. Lower the loader until the stand tubes are firmly on the ground and then dump the bucket so that it is also firml on the ground. There should be a slightly downward pressure. 3. Loosen the bolts from the rear of the subframe boots and swing bolt up into lock position. Operation and Maintenance GENERAL Refer to tractor Operator’s Manual for operating information on the tractor's hydraulic system. Hydraulic systems using auxiliary valves should have them located for easy reach from the tractor seat. Hoses should be connected in such a manner that pushing forward on valve handles lowers the boom or dumps the bucket. CAUTION: Always connect boom hoses to float section. Weight added to rear of tractor provides better traction and an easier, more efficient loader operation. Extra weight, along with widening the rear wheels, reduces the risk of roll-over. LOWER BOOM /j\ I WARNING I The smaller the tractor is, the easier it will roll. We recommend that weight be added to rear tires with liquid or by the installation of rear wheel weights. Where additional weight is required, a counterweight box can be fabricated for tractors with three-point hitches. Extra weight can also be added by the use of a heavy implement mounted to the three-point hitch. In cold weather, operate the tractor's engine at idle speed until the hydraulic fluid is warmed up. High engine speed when the hydraulic fluid is cold will cause the pump to wear prematurely. Under normal conditions, operate the tractor's engine at 1/2 throttle. Shift the tractor into a low gear before entering a pile of material to minimize strain on loader arms. A roll-over protective structure is also recommended. Trouble Shooting PROBLEM POSSIBLE CAUSE REMEDY Loader slow and/or will not dump. Quick couplers leaking. Hydraulic oil too heavy. Oil filter plugged. Hydraulic pump worn. Oil line restricted or leaking. Control valve does not shift properly. Air in hydraulic system. Cylinder leaks internally. Faulty valve. Check connections and compatibility or replace. Change or replace filter. Clean or replace filter. Repair or replace pump. Check all hoses and tubes for leaks, damage or restrictions. Replace damaged or restricted hoses or tube lines. Inspect, clean, repair or replace valve. Cycle lift cylinders and bucket cylinders several times to free system of air. Replace seals. Repair or replace valve. Loader chatters or vibrates when raising and lowering. Excessive movement at pivots Air leak in pump inlet line. Air in hydraulic system. Oil level too low. Worn bushings and/or pins. Check, tighten or replace inlet line. Cycle lift cylinders and bucket cylinders. Add oil as required. Replace bushings and/or pins. Pump noisy Inlet line restricted or leaking. Oil level too low. Pump worn or damaged. Check for air leaks, restrictions or collapsed hose. Tighten or replace hose. Clean filter if necessary. Add oil as required. Repair or replace pump. Oil leaks. Damaged fittings or hoses. Loose connections. \ Worn or damaged O-ring wiper seal in cylinder rod end. Worn or damaged O-rings in valve. Replace damaged parts. Tighten fittings. Install a seal repair kit. Install an O-ring repair kit. Insufficient lift capacity Improper hydraulic pump operation. Repair or replace pump. Load is greater than boom lift capacity. Check loader specifications. Internal boom cylinder leakage. Replace any worn parts and install a seal repair kit. Improper hydraulic valve operation. Repair or replace valve. Slow leakdown. Worn control valve. Worn cylinder piston seals. Have authorized dealer replace seals. Have authorized dealer replace seals. Excessive wear on bottom oil bucket Float position not used while operating Use float position provided on valve, and wear pads. loader. Hydraulic cylinders inoperative.
