Motion Control Damper Adjustment; Adjust Seat Switch (For All Units Except 31Hp Briggs & Stratton And 28Hp Kohler Efi Units) - Exmark LAZER Z Operator's Manual

Maintenance
creep in reverse (Figure 21). Move the motion
control lever to the reverse position and while
applying slight pressure to the lever allow the
reverse indicator spring to bring the levers back to
neutral. The wheel must stop turning or slightly
creep in reverse. When adjustment is complete,
tighten lock nuts onto ball joints.
10. Adjustment for the RH motion control lever:
Bring the RH motion control lever into the
neutral position.
Adjust the RH pump control rod length by
rotating the double nuts on the rod in the
appropriate direction until the wheels slightly
creep in reverse. Move the motion control lever
to the reverse position and while applying slight
pressure to the lever allow the reverse indicator
spring to bring the levers back to neutral. The
wheel must stop turning or slightly creep in
reverse (Figure 22).

Motion Control Damper
Adjustment
The top damper mounting bolt can be adjusted to
obtain a more desired motion control lever resistance.
See Figure 23 for mounting options.

Adjust Seat Switch (For all
Units Except 31HP Briggs
& Stratton and 28HP Kohler
EFI Units)
1. If necessary, adjust the seat actuator rod length
to where the machine will shut off when the
operator raises off the seat (with brake disengaged
or PTO engaged) but will continue to run with
operator in seat (a slight shift in weight should
not shut machine off).
Normal adjustment is when length of spring is
2.09 inches (5.3 cm) (with seat up).
Note: To prevent the engine from cutting out
when operating over rough ground, the unit is
equipped with a time-delayed seat switch. When
the operator raises off the seat with either the
brake disengaged or the PTO engaged, the engine
should stop after 1/2 second has elapsed.
2. To adjust seat switch actuator rod length, loosen
lock nut on bottom of the actuator rod (5/16
x 7 inch bolt) and adjust the nuts to move the
actuator plate/washer up or down on the rod,
then retighten.
