Safety
DANGER
DANGER
In certain conditions gasoline is extremely
flammable and vapors are explosive.
A fire or explosion from gasoline can burn
you, others, and cause property damage.
In certain conditions during fueling, static
electricity can be released causing a spark
which can ignite gasoline vapors. A fire or
explosion from gasoline can burn you and
others and cause property damage.
• Fill the fuel tank outdoors in an open
area, when the engine is cold. Wipe up
any gasoline that spills.
• Always place gasoline containers on the
ground away from your vehicle before
filling.
• Never refill the fuel tank or drain the
machine indoors or inside an enclosed
trailer.
• Do Not fill gasoline containers inside a
vehicle or on a truck or trailer bed because
interior carpets or plastic truck bed liners
may insulate the container and slow the
loss of any static charge.
• Do Not fill the fuel tank completely
full. Add gasoline to the fuel tank until
the level is 1/4 to 1/2 inch (6–13 mm)
below the bottom of the filler neck. This
empty space in the tank allows gasoline
to expand.
• When practical, remove gas-powered
equipment from the truck or trailer and
refuel the equipment with its wheels on
the ground.
• Never smoke when handling gasoline,
and stay away from an open flame or
where gasoline fumes may be ignited by
spark.
• If this is not possible, then refuel such
equipment on a truck or trailer from a
portable container, rather than from a
gasoline dispenser nozzle.
• Store gasoline in an approved container
and keep it out of the reach of children.
• If a gasoline dispenser nozzle must be
used, keep the nozzle in contact with the
rim of the fuel tank or container opening
at all times until fueling is complete.
• Add fuel before starting the engine.
Never remove the cap of the fuel tank or
add fuel when engine is running or when
the engine is hot.
WARNING
• If fuel is spilled, Do Not attempt to start
the engine. Move away from the area of
the spill and avoid creating any source of
ignition until fuel vapors have dissipated.
Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors has caused
cancer in laboratory animals. Failure to use
caution may cause serious injury or illness.
• Do Not operate without entire exhaust
system in place and in proper working
condition.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas
tank/container opening.
• Keep away from eyes and skin.
• Never siphon by mouth.
• Check that the operator’s presence controls,
safety switches, and shields are attached and
functioning properly. Do Not operate unless they
are functioning properly.

Operation
as shown in Figure 4, and the drive levers are released,
the drive wheels are engaged in the forward direction.
Note: Determine the left and right sides of the
machine from the normal operating position.
Operator Presence Control (OPC)
Levers
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.
Located on the upper handle assembly directly above
the handle grips.
Neutral Lock Latches
Controls
Located on the upper handle assembly on the ends
of the handle grips.
When these levers are depressed, the OPC system
senses that the operator is in the normal operator’s
position. When the levers are released, the OPC
system senses that the operator has moved from the
normal operating position and will kill the engine if
either the speed control lever is not in the neutral
position or the PTO is engaged.
These latches allow the operator to lock the drive
levers in a “neutral” position where the drive wheels
are not engaged in either a forward or reverse
direction.
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 right side of the control console.
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 the control console.
Drive Levers
The speed control lever controls the maximum
forward speed and is infinitely variable from neutral
0–6.2 mph (10.0 km/hr).
Located on each side of the upper handle assembly
ahead of and below the handle grips.
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,
Park brake must be disengaged to move speed control
out of neutral or engine will kill.

drive levers in the “drive” position.
Hydraulic System Air Purge
Service Interval: As required
Air must be purged from the hydraulic system
when any hydraulic components, including oil
filter, are removed or any of the hydraulic lines are
disconnected.
The critical area for purging air from the hydraulic
system is between the oil reservoir and each
charge pump located on the top of each variable
displacement pump (Figure 13). Air in other parts of
the hydraulic system will be purged through normal
operation once the charge pump is “primed”.
If either drive wheel does not rotate, it is possible
to assist the purging of the charge pump by
carefully rotating the tire in the forward position.
Note: It is necessary to lightly touch the charge
pump cap with your hand to check the pump
temperature. If the cap is too hot to touch, turn
off engine. The pumps may be damaged if the
pump becomes too hot.
If either drive wheel still does not rotate continue
with step 4.
4. Thoroughly clean the area around each of the
charge pump housings.

housing. Retighten the capscrews. Do this for
both pumps.
Note: Hydraulic reservoir can be pressurized up
to 5 psi to speed this process.
6. If either drive wheel still does not rotate, stop
and repeat steps 4 and 5 above for the respective
pump. If wheels rotate slowly, the system may
prime after additional running. Check oil level
as stated in Check the Hydraulic Oil Level
section.
7. Allow unit to run several minutes after the charge
pumps are “primed” with drive system in the full
speed position. Check oil level as stated in Check

All implied warranties of merchantability (that the

product is fit for a particular purpose) are limited to the
duration of the express warranty.
Some states do not allow exclusions of incidental or
consequential damages, or limitations on how long an
