I. Spray Boss Control - Engages and disengages speed boss. Forward is
engage and all the way back is disengage. When the lever is engaged it
sets a stop for the accelerator. The accelerator pedal must be used to
maintain this speed. To adjust speed use the knob on the end of the lever,
counter clockwise increases speed and clockwise decreases speed. Disen-
gage the lever and you will have full accelerator pedal range.
J. Hand Throttle - The hand throttle is used to regulate engine speed.
K. Choke - The choke is used in starting the engine. Pull choke out to close
choke plate when starting a cold engine. Push in when engine starts. A warm
engine may not require "choking" to start.
L. Boom Switches (Electric Lift Kit)
M. Boom Levers (Hydraulic Lift Kit)
N. Park Brake - The park brake is only a parking brake. Pull back to release,
push forward to apply. Some adjustment can be made by turning the knob
clockwise to tighten and counter clockwise to loosen.
O. Accelerator Pedal - This pedal controls ground speed. Press pedal to
increase speed. Varying the amount of movement of the pedal will vary
the ground speed.
P. Reverse Pedal - This pedal controls ground speed in the reverse
direction.
When pedals are released the hydrostatic transmission centers and
stops the vehicle with a braking action.

trol switch to work.
