Lawnmowers and all power equipment, can be potentially dangerous if used improperly. SAFETY REQUIRES GOOD JUDGEMENT, CAREFUL USE IN ACCORDANCE WITH INSTRUCTIONS AND COMMON SENSE. MANUAL NO. [. . . ] Place two 2x4’s on edge under the cutting deck from front to rear and lower the deck down onto the 2x4’s. Adjust the four upper chain bolts to the center of the slot in the deck lift arms. NOTE: make sure deck lift blocks are tightly bolted to the frame (See Fig 3). Return the deck height lever to the transport position (5" cutting height) and check the center to center distance of the swivels. Place deck in the 5" cutting height and measure from the cutting edge of the blade to a flat surface to check deck cutting height. Check to make sure the bolt head in the spring loaded idler pulley, on the left side of the engine deck is positioned between the two alignment holes in the left support plate (See Fig 4). If adjustment is necessary, loosen the adjustable idler pulley on the right hand side of the engine deck so it can move up and down in the slot. Place a wrench on the 3/8" nut in the center of the spring loaded idler pulley and rotate the idler upward to relieve the tension on the belt. Recheck alignment of the bolt on the spring loaded idler. Figure 4 THROTTLE LEVER TENSION: 1. If throttle lever becomes loose, tension may be adjusted by tightening the pivot bolt. The pivot bolt holds the throttle arm to the throttle mounting bracket which is located under the console. Put seat in rear slide position, tilt seat forward, remove seat stop rod bolt and nut, tilt seat forward to rest on front frame. Move the motion control lever to the neutral position then pull the lever back until the clevis pin (on the arm below the pivot shaft) comes into contact with the end of the slot. Check where motion control lever is relative to the neutral slot in the console. The lever should be centered to allow it to pivot outward into the neutral slot. Apply slight rearward pressure to the motion control lever and turn the head of the adjustment bolt in the proper direction until the lever is centered in the neutral slot. NOTE: if properly adjusted the motion control levers will return to neutral from the reverse position and reverse motion will stop if levers are released. Figure 5A Figure 5B 9 ADJUSTMENTS MOTION CONTROL LINKAGE ADJUSTMENT: 1. Raise rear of the unit and block it up so the wheels are free to rotate. Motion control levers located on each side of the console control direction of movement. The left lever controls the flow of oil from the left hydro pump to the left wheel motor. The right lever controls the flow of oil from the right hydro pump to the right wheel motor. 10 OPERATING INSTRUCTIONS NOTE: To begin motion the operator must be in the seat and the brake disengaged before the levers can be moved from the neutral slots or the engine will kill. By moving the levers an equal amount forward or back the mower will move in a straight line in that direction. [. . . ] Safety interlock system: Check daily and never operate the mower if this system is not functioning properly. The starter should crank only when the operator is in the seat, the park brake set, blades off and the motion control levers in the neutral slots. If the mower starts with any of these controls on or in an operating position, turn the mower off and repair the system immediately. Hardware: Stop engine and remove key thoroughly inspect the entire machine for any missing or loose hardware. [. . . ]
