If this is not done, the frame will not remain standing. _ A 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. _'_ 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 busfiings 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, ^strictions 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. Load is greater than boom lift capacity. Internal boom cylinder leakage. Improper hydraulic valve operation. Repair or replace pump. Check loader specifications. Replace any worn parts and install a seal repair kit. 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 and wear pads. Float position not used while operating loader. Use float position provided on valve. Hydraulic cylinders inoperative. Hose from control valve improperly connected. Refer to plumbing diagrams.

Replace closed center plug with relief and install short plug in place of power beyond General Notes and Instructions to the Operator Regarding ALLIED HSL Loader Operations The hydraulic self-leveling system (HSL) utilizes two metering cylinders which displace oil into or out of the bucket cylinders as the loader is raised or lowered. The cylinder volumes and geometry’s are carefully matched for each loader model to provide the correct amount of oil to keep the bucket level after it is initially leveled. The HSL system incorporates two relief valves which are only utilized if the bucket cylinders are at either end of the stroke. If the loader is raised with the bucket fully dumped, oil will be bypassed at high pressure into the lower side of the lift cylinder circuit. If the loader is lowered with the bucket fully rolled back, oil will be bypassed at high pressure into the raised side of the lift cylinder circuit. Note that these two conditions are likely to occur only intermittently, and although the pump will be forced to supply oil at a higher pressure no damage to the loader components will occur. It is, however, recommended to avoid the above situations and keep the bucket somewhat level while raising or lowering the loader for smoother operation. Note that the large volume (piston side) of the leveling cylinders is connected to the large volume of the bucket cylinders, and the small volume (rod side) is connected between the two sets of cylinders. The effect of this configuration is to create a breakout force “boosf if the bucket cylinders are pressurized toward the rollback position during breakout. The opposite effect of the above situation is that the loader will have poor l...
