3.15 If machine is shipped without muffler installed, install muffler with hardware
provided.
3.16 SERVICE ENGINE: Refer to Engine Owner’s Manual.
3.17 SERVICE HYDRAULIC OIL
The machine is shipped with hydraulic oil filled to the top of the baffle in the
reservoir. 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.
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.
3.18 GREASE UNIT: NOTE: UNIT IS NOT GREASED AT THE FACTORY.
Refer to 5.1.14, for locations and grease amounts.
3.19 Follow pre-start instructions as outlined in Section 4.2.
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.
3.20 Perform any needed adjustments as outlined in the Adjustment Section.
4. OPERATION INSTRUCTIONS
4.1 Controls
4.1.1 Familiarize yourself with the controls and operation of the unit.
Carefully read the following information about the controls and their operation.
4.1.2 Operator Presence Control (OPC) Levers
: Located on the upper handle
assembly directly above the handle grips. See Figure 5. 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.
4.1.3 Speed Control Lever
: Located in middle of control console, it controls the
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.
4.1.4 Drive Levers
: Located on each side of the upper handle assembly directly below
the handle grips (See Figure 5). 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 5, 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.
