DANGER
PINCH POINT - SPRING LOADED DOOR
When lowering the door on the GHS
catcher, BE VERY CAREFUL to keep
hands, fingers, 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.
WARNING
DO NOT test the Grass-Pak
®
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
example, wet heavy grass will fill the catcher dif-
ferently than dry fluffy grass, causing the signal to
come on a little sooner or later than usual. Pri-
marily, 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 (regardless of mowing conditions).
