DANGER
PINCH POINT - SPRING LOADED DOOR
When lowering the door on the GHS
catcher, BE VERY CAREFUL to keep
hands, ngers, etc. out of the hinging
mechanism and away from the door frame
as the door closes. The springs that hold
the door closed during operation are very
powerful, and the door can slam shut with
considerable force.

switch with
the engine running. Projectiles CAN be
thrown out of the grass delivery spout
and CAN cause serious injury to bystand-
ers or property damage.

3. If adjustment is required, loosen front adjust-
ment nut then move aluminum shaft and vane to
the recommended measurement. Adjustments
should be done in very small increments check-
ing the measurement each time until the recom-
mended measurement is achieved.
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 ll the catcher differently
than dry uffy 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 overlling
and clogging of the grass delivery chute begins (re-
gardless of mowing conditions).
