OPERATING SYSTEMS
POWER PORTS-
On the front of the side console there are two power
ports (fig. 4.27-1) for extra equipment to be plugged in. They are each pro-
tected by a 15 amp fuse. They are not intended for the permanent connection of
extra systems to the sprayer. There is a terminal strip intended for the installa-
tion of extra radios and computer equipment. See the SERVICE section E on
the electrical components.
FIG. 4.27-1
FOAMER SWITCH–
The foamer switch on the top of the hydrostatic lever (fig. 4.27.2, item A) controls
the foam option on either side of the machine. This option is not available on the GST 20 machines.
MAIN SOLUTION SWITCH–
The main spray control (fig. 4.27-2, item E) in the lower middle of the hy-
drostatic lever is so the operator can turn all spray valves off at one time. See OPERATING SYSTEMS sec-
tion D on spray systems for more information. This switch is also used for the
brushes on the plow, refer to the plow manual for more information.
FORWARD CONTROL–
The hydrostatic lever is responsible for the
direction of motion of the machine. To move forward, slowly move the hydro-
static lever forward. (fig. 4.27-2, item F)
REVERSE CONTROL–
To move the machine in reverse, slowly move
the hydrostatic lever backward. (fig. 4.27-2, item H) Be sure that the machine
is clear of all dangers before putting it in reverse.
NEUTRAL POSITION–
The neutral position is also the stop or brake
position. (fig. 4.27-2, item G) The neutral position must be met before chang-
ing direction of the machine. There are several functions that can not be per-
formed if the machine is not in the neutral position.
More information on the forward, reverse, and neutral positions of
the hydrostatic lever is available in section B of the OPERATING SYS-
TEMS.
LIFT, LEVEL, HORIZONTAL FOLD-
(fig. 4.27-2, items B,C, &D) are all a part of the hydraulic system.
A complete explanation of their functions can be found in section C of the OPERATING SYSTEMS. Refer to
the plow manual for information about their plow operation functions.
