Adjustment (When Horn Sounds at the Wrong Time)

Very little, if any, adjustment to the Grass-Pak®switch is required. However, to fine tune the timing of the full signal, the vertical position of the switch vane is adjustable approximately 3/4 in. (1.9 mm).

1.Loosen the screw mounting the vane on the switch and adjust the position of the vane as fol- lows:

a.Move the vane UP to delay the signal.

b.Move vane DOWN to advance the signal.

2.Retighten the screw.

NOTE: It will not be possible to adjust the switch to give a signal at the precise instant the catcher is full for a wide variety of mowing conditions. For exam- ple, wet heavy grass will fill the catcher differently than dry, fluffy grass, causing the signal to come on a little sooner or later than usual. Primarily, the switch should be adjusted to give the “full” signal with a little advance warning before overfilling and clogging of the grass delivery chute begins (re- gardless of mowing conditions).
