Readjust the clutch as described above. Adjusting the PTO Clutch The PTO clutch should be adjusted whenever there is less than .5 inches of free travel in the clutch lever when it is in the “On” position. See Figure 6 to see where this free travel is measured. The free travel should be between .5 inch and 1.0 inch. • Stop the engine and lock the brake. • Loosen the bolts holding the switch bracket and push the bracket down. • Raise the rear fender. • Push the PTO lever to “On”. • Disconnect the PTO control from the transmission lever. 12 Adjustments (Continued) • Turn the control rod to change the free travel. Each turn will change it by about .25 inch. Turn clockwise to increase and counterclockwise to decrease the free travel. • Reconnect the control rod to the transmission lever. Check for correct free travel. Repeat above three steps if necessary. • Put the PTO control in the “Off” position. • Move the switch bracket up until the switch closes (makes a circuit). Tighten the switch bracket hardware. CAUTION: Make sure that the PTO control assembly does not rest on the switch body. Adjusting the Steering System Adjustment of the steering gear is usually needed whenever there is more than 2 inches of free play in the steering wheel. To adjust the steering gear: • Loosen the lock nuts on both adjusting bolts (Figure 4). • Turn the steering wheel to the right as far as it will go. • Turn the adjusting nut on the left side adjusting bolt clockwise with your fingers until it is tight. Then back the nut off one fourth turn. • Tighten the lock nut against the adjusting nut being careful not to move the adjusting nut. • Turn the steering wheel to the left as far as it will go. • Repeat the above two steps for the right side adjusting nut. • Check for tightness or backlash in the steering gear through the full range of the steering wheel rotation. There should be no noticeable tightness or backlash in the rack and pinion mesh. If there is, repeat above steps as required. Upon completion of the steering gear adjustment, recheck the steering wheel free play. If the free play is still excessive, look for loose steering arms on the king pins, loose or worn ball joints, or other signs of wear. Tighten or replace as required. Adjust the front wheel toe-in as follows: • Rotate the steering wheel until the two steering arm weldments are parallel to the frame side. • On 13.5 HP and 16 HP engine units, loosen the jam nuts on the tie rods and disconnect the outside ball joint. Rotate the front tires by hand so that the distance between the front centerline of the tire is 1/8” to 1/2” less than the Distance between the rear centerline. Adjust the tie rods so that the ball joint can be connected to the tie rod arm without moving the tire and so that the tie rods are the same length. Tighten the jam nuts. • On 20.5 HP units, loosen the jam nuts on the tie rods and rotate the tire rod tube so that the front centerline of the tire is 1/8” to 1/2” closer than the rear centerline and so that the tie rods are the same length. Tighten the jam nuts. Servicing the Spark Plug(s) To clean or change a spark plug: • Stop the engine, lock the brake, and raise the seat pan weldment. • See your engine manual for further instructions. Servicing the Hydraulic Lift WARNING: Keep body and hands away from pin holes or nozzles which eject hydraulic fluid under pressure. Use paper or cardboard and not hands to search for leaks. Be sure to stop the engine and put the attachment in the down position before doing any work on hydraulic parts. WARNING: Make sure all hydraulic fluid connections are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system. Hydraulic fluid escaping under pressure may have sufficient force to penetrate skin and cause serious injury. Foreign fluid injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result. Check the hydraulic fluid level when the hydraulic lift will not raise the attachment or leaks are observed. To check the hydraulic fluid level: • Clean the area around the reservoir and cap. • Remove the cap. • The correct hydraulic fluid level is one inch from the top of the reservoir. Add Dextron II ATF to maintain this level. 13 Adjustments (Continued) Adjusting the Range Selector • Move the Hi-Lo shift lever as far as it will go in both directions. Measure the distance between the lever and the end of the slot. This distance should not be less than 5/16”. • Adjust the clevis so that the clearance between the Hi-Lo shift lever and the control cover plate slot is equal for both positions of the lever. Adjusting the Seat The seat has 4” of front-to-rear adjustment. To adjust the seat, pull the adjustment lever out and move the seat forward or backward. Release the lever and ensure that the seat is locked into position. 14 Storage Storing the Unit • Do the daily and 25-hour maintenance, but do not add ...
