Choke Control (All Models Except
EFI)
Located on the LH side of the control console (see
Figure 4).
The choke is used to aid in starting a cold engine.
Pulling up on the choke will put the choke in the
"ON" position and pushing down on the choke will
put the choke in the "OFF" position. Do Not run a
warm engine with the choke in the "ON" position.
Throttle Control (X-Series EFI Models
Only)
Located on the center of the control console (black
lever).
The throttle is used to control engine speed. Moving
the throttle lever forward will increase engine speed
and moving the throttle lever to the rear will decrease
engine speed.
The machine has a clutch saver, which allows the
throttle to automatically reduce engine RPM:
• when the PTO switch is engaged or disengaged.
• when stepping off the platform with the PTO
engaged.
Engine RPM will resume its setting when the PTO is
reset.
Throttle Control (All S-Series and
X-Series Non-EFI Models Only)
Located on the center of the control console (red
lever).
The throttle is used to control engine speed. Moving
the throttle lever forward will increase engine speed
and moving the throttle lever to the rear will decrease
engine speed. Moving the throttle forward into the
detent is full throttle.
Park Brake Lever
Located on the left side of the machine.
g345124
The brake lever engages a parking brake on the drive
wheels and locks the motion controls in neutral.
Note: The LCD indicator appears in the message
display on the front console when the park brake is
engaged (see Figure 4 and Figure 7).
Pull the lever up and rearward to engage the brake.
Push the lever forward and down to disengage the
brake.
When parking on a steep slope, the wheels must be
chocked or blocked in addition to the brake being
engaged. The machine must be tied down and brake
engaged when transporting.
Park brake must be disengaged before motion control
can move out of neutral.
Ignition Switch
Located on the RH side of the control console.
The ignition switch is used to start and stop the
engine. The switch has three positions "OFF", "ON"
and "START". Insert key into switch and rotate
clockwise to the "ON" position. Rotate clockwise to
the next position to engage the starter (key must be
held against spring pressure in this position). Allow
the key to return to the "ON" position immediately
after the engine starts.
