- Dismounting Loader and Mounting Loader to Tractor
- Dismounting Loader
- 1. Locate tractor and loader on firm level ground.
- 2. Level the bucket and lower it to the ground. Engage the tractor brakes and shut off the tractor engine. Move the lift control lever back and forth several times to relieve pressure in the lift cylinders
- 3. Loosen the 3/4 x 3-1/2 cap screws which clamp the hinges closed around the midmounting tubes. Remove cap screws, washers and lock nuts. Place washer onto cap screw, hold hinge open as wide as possible, then insert cap screw through the hole provid...
- 4. Remove the rubber strap which secures the hoses to the loader front support bracket. Remove any tie straps which attach hoses to tractor or brackets.
- 5. Start the tractor engine and release tractor brakes. Lower loader boom slightly as necessary to distribute the weight of the loader equally between the front mounting bracket and midmounting brackets. This can also be accomplished by using the boo...
- 6. Move lift and bucket control levers back and forth several times to relieve pressure on the lift and bucket cylinders. Disconnect quick couplers between the loader and tractor. Hang hoses over the side frame for storage. If tractor is equipped wit...
- Preparing Stored Loader for Mounting
- 1. Slowly back the tractor up to the loader until hoses will reach from loader to tractor remote couplers. Engage the tractor brakes and shut off the tractor engine.
- 2. Making sure quick couplers are clean, connect quick couplers between the tractor and loader. Match color coded bands when connecting couplers.
- 3. Start the tractor engine and release tractor brakes. Operate the lift control valve to extend the lift cylinders as far as possible.
- 4. Once the lift cylinders are fully extended, shut off the tractor engine and engage the tractor brakes. Move the loader control levers back and forth to relieve pressure in the cylinders, then disconnect the quick couplers.
- 5. Start the tractor engine, release the tractor brakes, slowly drive the tractor up to loader
- 1. Slowly drive the tractor up to the loader until hoses will reach from 1-lever auxiliary valve to tractor. Engage tractor brakes and shut off tractor engine.
- 2. Reinstall valve support assembly into the valve support guide tube. Connect quick couplers by matching color coded bands.
- 3. Start the tractor engine and release tractor brakes. Operate the lift control to extend the lift cylinders as far as possible.
- Mounting Procedure
- 1. Slowly drive the tractor up to loader until hoses will reach from the loader to the tractor. Engage the tractor brakes and shut off tractor engine.
- 2. Connect quick couplers between tractor and loader, matching color coded bands.
- 3. Start tractor engine and release tractor brakes. Slowly drive the tractor ahead while activating lift control lever to retract lift cylinders. Position tractor so hinges hook midmounting bracket tubes as loader side frame uprights rotate.
- 4. Put the tractor in neutral. Retract the lift cylinders bringing the side frame channels up so front support bracket tube contacts front mounting bracket channel. Move the tractor ahead so front support bracket tube engages in front mounting bracke...
- 5. Remove 3/4 x 3-1/2 cap screw with washer which blocked hinge open and remove elastic lock nut from extra threads on hinge carrier bolt. Clamp hinge of upright around the midmounting tube. Insert 3/4 x 3-1/2 cap screw down through upright and hinge...
- 6. Hook the rubber strap from hoses to loader support bracket. Reinstall reusable tie straps.

- MAINTENANCE SECTION
- Lubrication Schedule
- Daily Maintenance
- 1. Check fluid level of tractor hydraulic system before starting each day’s operation. If necessary, add hydraulic oil as recommended in your tractor operator’s manual.
- 2. After every four hours of operation, lubricate all twelve grease fittings; one at each end of lift boom arms and one at rod and base ends of each lift and bucket cylinder.
- 3. After every ten hours of operation, check all hardware and tighten where required.
- 4. Replace hoses immediately if they are damaged by a cut or scrape, extruded at the fittings or leaking. Hydraulic oil leaks should be repaired promptly to avoid loss of oil and serious personal injury from escaping oil.
