manual abstract
There should be slight downward pressure. 3. Loosen the bolts from the rear of the subframe boots and swing bolt up into lock position. 17 Removing the Loader from Your Tractor (Continued) 4. Roll back the bucket slightly and simultaneously extend or retract the lift cylinders to free hooks from spools. Then slowly back up the tractor. 5. Once the subframe is clear of the boot and the hook is clear of the mounting boss, roll back the bucket all the way. This raises the rear uprights of the loader. NOTE: On some mountings, the lift cylinders must be extended more while the tractor is backing up, so that the subframes clear the front axle. 6. Continue backing up until the loader is clear. CAUTION! Be sure the hoses DO NOT get pinched or catch on any frame members while backing up. 7. After the loader is clear, retract the lift cylinders to protect the shafts and disconnect the hydraulic lines at quick couplers. PROBLEM POSSlBLE CAUSE REMEDY Loader slow and/or will not dump. Quick couplers leaking. Check connections and compatibility or replace. Hydraulic oil too heavy. Change or replace filter. Oil filter plugged. Clean or replace filter. Hydraulic pump worn. Repair or replace pump. Oil line restricted or leaking. Check all hoses and tubes for leaks, damage or restrictions. Replace damaged or restricted hoses or tube lines. Control valve does not shift properly. Inspect, clean, repair or replace valve. Air in hydraulic system. Cycle lift cylinders and bucket cylinders several times to free system of air. Cylinder leaks internally. Replace seals. Faulty valve. Repair or replace valve. Loader chatters or vibrates when Air leak in pump inlet line. Check, tighten or replace inlet line. raising and lowering. Air in hydraulic system. Cycle lift cylinders and bucket cylinders. Oil level too low. Add oil as required. Excessive movement at pivots Worn bushings and/or pins. Replace bushings and/or pins. Pump noisy Inlet line restricted or leaking. Check for air leaks, restrictions or collapsed hose. Tighten or replace hose. Clean filter if necessary. Oil level too low. Add oil as required. Pump worn or damaged. Repair or replace pump. Oil leaks. Damaged fittings or hoses. Replace damaged parts. Loose connections. Tighten fittings. Worn or damaged O-ring wiper Install a seal repair kit. seal in cylinder rod end. Worn or damaged O-rings in valve. Install an O-ring repair kit.

Trouble Shooting 18 19 General Notes and Instructions to the Operator Regarding ALLIED TSL Loader Operations 1. The true self levelling system (TSL) utilizes mechanical linkages to maintain bucket level while raising and lowering. The pivot plate weldment, levelling tubes and linkages have been developed to ensure that the bucket remains at the same position throughout its range of motion. This feature is standard with 3.00” diameter bucket cylinders. 2. The TSL system incorporates a relief and anticavitation manifold to provide extra dump at ground and rollback at full lift height. This feature is available on 3.00” bucket cylinders only. If the loader is raised with the bucket fully dumped, oil from the bucket piston side will be bypassed at high pressure to the bucket shaft side and the lift shaft side as the quick attach contacts the dump stop. If the loader is lowered with the bucket fully rolled back, oil from the bucket shaft side will be bypassed at high pressure to the bucket piston side and makeup will be provided by t...
