Exmark Lazer HP manual Swivel Adjustment Spring Compression Adjustment

e)Raise the deck to the 5” (12.7 cm) height position (also transport position) and take all force off of the two large deck lift springs by loosening the nuts at the front of each spring. See Figure 12.

f)For 60” units - Lower the deck to the 1-1/2” (3.81 cm) height position.

For 72” units – Lower the deck to the 1-1/2” (3.81 cm) height position. Force the left rear deck support arm downward about 1/4” (6.4 mm) to get the deck to rest at the 1-1/2” height position. Place locking pliers between the rear swivel and spring stop to hold the deck in this position. See Figure 12.

g)Place a 3/4” (19 mm) thick block of wood under each of the two (2) rear anti- scalp roller brackets and place one under one of the front center anti-scalp roller brackets.

h)Loosen the two (2) top chain bolts in slots in the rear deck lift arms. Loosen jam nuts and back off the socket head adjusting screws on the bottom of the arms until the chains are just loose. Turn the socket head adjusting screws in until slack is taken out of each chain. Tighten the jam nuts. Tighten the chain bolts in the deck lift arms making sure they don’t move while tightening.

i)Loosen the four (4) nuts which secure the front swivels (two per side) until the front chains are loose and front of deck is supported by the 3/4” (19 mm) block. Do not loosen the front chain hardware.

j)On left side, adjust front swivel using the locking nut behind the swivel until the front chain is tight and all slack is removed from linkage. Do not lift front of deck off 3/4” (19 mm) block. Secure front swivel using locking nut in front of swivel. Repeat for right side.

k)Recheck that the 3/4” (19 mm) blocks fit just snugly under the brackets and that the tension on all the chains are approximately equal. Make sure all chain attachment bolts are tight. Reposition anti-scalp rollers and tighten securely.
