4. OPERATION INSTRUCTIONS

4.1 Controls

4.1.1 Familiarize yourself with the controls and operation of the unit.
4.1.2 Operator Presence Control (OPC) Levers: Located on the upper handle
4.1.3 Speed Control Lever: Located in middle of control console, it controls the
4.1.4 Drive Levers: Located on each side of the upper handle assembly directly below
the crate. Loosen the clamp, rotate the muffler ahead and secure the bracket on the
muffler to the bracket on the engine with the hardware provided. Tighten the clamp.
Run the machine for approximately 15 minutes to allow any extra air to purge out
of the hydraulic system. Check hydraulic reservoir and if necessary fill the
reservoir to the appropriate level with Mobil 1 15W-50 synthetic motor oil. Replace
hydraulic reservoir cap and tighten until snug. Do not overtighten.
NOTE: The baffle is labeled "HOT" and "COLD". The oil level varies with the
temperature of the oil. The "HOT" level shows the level of oil when it is at 225° F.
(107°C). The "COLD" level shows the level of the oil when it is a 75°F (24°C). Fill to
the appropriate level depending upon the temperature of the oil. For example: If the
oil is about 150°F (65°), fill to halfway between the "HOT" and "COLD" levels. If the
oil is at room temperature (about 75°F (24°C)), fill only to the "COLD" level.
Refer to 5.1.13, for locations and grease amounts.
NOTE: After starting the engine and engaging the hydro drive, if either of
the drive wheels acts sluggish or will not rotate at all, stop engine and refer
to Section 5.1.10 on the Hydraulic System Air Purge procedure.
Carefully read the following information about the controls and their operation.
assembly directly above the handle grips (See Figure 6). 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.
maximum forward speed and is infinitely variable from neutral (0 mph) to 6.2
mph. Park brake must be disengaged before speed control lever is moved out
of neutral or engine will kill.
the handle grips (See Figure 6). 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, as
shown in Figure 7, 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.
