3.17 Connect wiring harness.
Route the long unattached portion of the wiring harness up the left handle and
under the console. On 15 HP Kawasaki units, connect the connector on the end
of the shorter lead to the key switch. Connect the two flag terminals to the OPC
switch in any order. Continue routing this lead down the right side of the handle
and connect the connector on the end of it to the park brake switch. Fasten the
harness to the left hand side of the handle with two small wire ties, from bolt bag,
one at the upper end of the handle next to the console and one at the very lower
end of the handle where it attaches to the fuel tank support. Repeat for the right
side. Using two small ties from the bolt bag, fasten the harness to the two small
holes in the channel under the console.
3.18 Service Engine: Refer to Engine Owner's Manual.
3.19 Service Hydraulic Oil: The machine is shipped with hydraulic oil 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.
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.
3.20 GREASE UNIT: NOTE: UNIT IS NOT GREASED AT THE FACTORY.
Refer to 5.1.13, for locations and grease amounts.
3.21 Follow pre-start instructions as outlined in 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.
3.22 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 8). 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 8). 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 9, and the drive levers are released,
the drive wheels are engaged in the forward direction.
