Operation
Drive Levers
Located on each side of the upper handle assembly
ahead of and below the handle grips (see Figure 4).
These levers individually control the speed and
direction of each drive wheel. When the speed
control lever is moved out of the neutral position
and the neutral lock latches are moved into the drive
position and the drive levers are released, the drive
wheels are engaged in the forward direction.
Squeezing the left hand and/or right hand lever
causes the left hand and/or right hand drive wheel
respectively to slow down, stop, or reverse, depending
on how far each drive lever is “squeezed”. Squeezing
the drive levers beyond the neutral position causes
the drive wheels to engage in the reverse direction
regardless of the position of the neutral lock latches
and the speed control lever.
Neutral Lock Latch
Located at the end of the handles.
The purpose of these latches is to allow the operator
to lock the drive levers in a "neutral" position where
neither of the drive wheels are engaged in either a
forward or reverse direction (see Figure 4).
Park Brake Lever
Located on the right side of the unit above the
hydraulic tank.
The brake lever engages the park brake on the drive
wheels.
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 unit must be tied down and brake
engaged when transporting.
Park brake must be disengaged to move speed control
out of neutral or engine must begin shutdown.
Choke Control
Located on the front left corner of the fuel tank
support.
Choke is used to aid in starting a cold engine. The
choke control is pulled out to be in the “ON” position
and pushed in to be in the “OFF” position. Do Not
run a warm engine with choke in the “ON” position.
Throttle Control
Located on the on the control console right side.
The throttle is used to control engine speed. Moving
the throttle control forward will increase engine speed
and moving it to the rear will decrease engine speed.
Moving the throttle forward into the detent is full
position.
Speed Control Lever
Located in middle of control console.
The speed control lever controls the maximum
forward speed and is infinitely variable from neutral
0–6.2 mph (10.0 km/hr).
Park brake must be disengaged to move speed control
out of neutral or engine must begin shutdown.
“Off-Run” Switch
Located on the control console.
Turn the key to the “Run” position to allow the
engine to be started. Turn the key to the “Off ”
position to shut engine off.
Fuel Shut-Off Valve
Located in the fuel line midway between the tank
and engine.
The fuel shut-off valve is used to shut off the
flow of fuel when parking inside a building, during
transportation to and from the job sites, and when
the machine will not be used for a few days.
Rotate valve 1/4 turn clockwise to shut fuel off.
Rotate valve 1/4 turn counterclockwise to turn fuel
on.
Drive Wheel Release Valves
Located on the top rear corner of the hydrostatic
pumps.
Drive wheel release valves are used to release the
hydro-static drive system to allow the machine to be
moved by hand without the engine running.
With a 5/8 wrench, turn both valves one turn
counterclockwise to release the drive system.
