5.2.11 Motion control linkage adjustment.
WARNING
POTENTIAL HAZARD
♦
Engine must be running and drive wheels must be
turning so motion control adjustment can be performed.
WHAT CAN HAPPEN
♦
Contact with moving parts or hot surfaces may cause
personal injury.
HOW TO AVOID THE HAZARD
♦
Keep fingers, hands, and clothing clear of rotating
components and hot surfaces.
CAUTION
POTENTIAL HAZARD
♦
Raising the mower deck for service or maintenance
relying solely on mechanical or hydraulic jacks could be
dangerous.
WHAT CAN HAPPEN
♦
The mechanical or hydraulic jacks may not be enough
support or may misfunction allowing the unit to fall,
which could cause injury.
HOW TO AVOID THE HAZARD
♦
DO NOT rely solely on mechanical or hydraulic jacks for
support. Use adequate jack stands or equivalent
support.
a) This adjustment must be made with the drive wheels turning. First raise
the frame and block up so that drive wheels can rotate freely.
b) Remove the electrical connection from the seat safety switch, located directly
to the left of the seat switch assembly beside the hydraulic oil reservoir.
Temporarily install a jumper wire across the terminals in the connector of
the wiring harness.
c) Run the unit at least 5 minutes with the drive levers at full forward speed
to bring hydraulic system oil up to operating temperature.
d) Tilt seat forward.
e) Loosen locknuts from the ball joints on the two rods which connect the
motion control assemblies to the pump control arms (See Fig 10).
NOTE: The nuts to the rear of the unit on each rod have left-hand threads.
