ADJUSTMENT
To adjust the drive chains, the body must be
removed and shims added behind the transaxle.
Loosen 4 bolts which hold the transaxle to the
frame. Insert shims as needed for adjustment
between transaxle and mount plates. When properly
adjusted, the slack span at the mid -point of the
chain should have a total possible movement
perpendicular to the chain of about 9/16". Tighten
the 4 bolts which hold the transaxle to the frame.
Replace chain when rollers become loose, chain
breaks, or chain fails to operate properly.
LUBRICATION
1. Chains: Proper lubrication is important for
effective roller chain operation. Use high quality
lubricating oil (do not use grease or extra heavy
oil) and apply drops of oil to the chain joints
every 10-15 hours of operation.
2. Front Caster Assembly: Each caster assembly
has a grease fitting located on the under side of
the bearing. For best results, use any good
multi-purpose grease every 10-15 hours of
operation.
3. All other Bearings: All other bearings o n your
mower are sealed and require no lubrication.
WHEELS AND TIRES
Correct tire pressure is essential to the correct
operation of the machine. The correct pressure for
the drive tires is 8-10 Ibs. The front tires should be
inflated to 20-24 Ibs. Lug nuts should be checked
periodically.
