TRACTOR & SAFETY POINTERS The use of good judgment and common sense is necessary by the operator in using this loader. The front and rear wheels should be set for the widest wheel tread to assure best stability. Use extra caution when rear wheel weights and tire ballast are added to a loader-equipped tractor.
ATTACHING LOADER IMPORTANT: Never attempt loader attachment on grades which are not reasonably level. 1. Check to be sure that the surfaces of the mounts are free of obstructions. (Fig 8-1) 2. Drive the tractor slowly and carefully in between the loader arms only far enough to permit hook-up of the hydraulic system hoses.
ATTACHING BUCKET 1. Raise handles until they stop. 2. Then tip adapter down-ward to about 60 Deg. 3. Drive into bucket and aim the adapter toward the center of the back of the bucket and lower the adapter below the lip on the bucket. 4.
DETACHING LOADER IMPORTANT: Never attempt loader attachment on grades which are not reasonably level. 1. Raise loader frame slightly to permit loader stand reengagement. (Fig 10-1) 2. Lower bucket to ground and tip slightly forward to apply pressure to mount connection. Note: This will prevent the loader from advertently rocking forward when the mount pins are removed and uprights are disengaged from it’s cradle.
OPERATION WARNING: Never allow anyone to operate the loader until they have carefully reviewed and understood this owners manual. FILLING THE BUCKET: Approach and enter the pile with the bucket level. Roll bucket back gradually as the loader moves through the pile. RAISING THE BUCKET: WARNING: Make sure material in bucket cannot spill out on to tractor when loader boom is raised.
