Electronic Fuel Injection (EFI) System -
EFI Models
EFI is an electronically-controlled fuel management system
which is monitored by an Electronic Control Unit (ECU). A
Malfunction Indicator Lamp (M.I.L.) will illuminate if problems
or faults are detected. Servicing by an authorized dealer is
necessary.
CAUTION
Do not disconnect or reconnect ECU wiring harness
connector or any individual components with the ignition
switch in the "ON" position. This can send a damaging
voltage spike through the ECU.
Unplug harness from ECU before performing any welding
on equipment.
Fuse Location and Identification
The electrical system for this unit is equipped with two
replaceable fuses. See the chart below for the circuit,
amperage, and approximate location of the fuses.
Circuit Amperage Approximate Location
Main 25 amp Instrument control
panel.
PTO Clutch 15 amp Behind the seat on the
left hand side of the
machine.
Check / Fill Transmission Oil Level
This unit is equipped with two transmission oil tanks. One
transmission oil tank only supplies oil to one transmission.
The level of oil in both transmission tanks must be checked,
and if necessary, filled.
Oil Type: SAE 20W-50 motor oil
1. Locate the transmission oil tanks (B, Figure 24) by raising
the seat plate of the unit.
2. Check the oil level when the unit is cold. The oil should be
up to the "FULL COLD" mark (A) on the transmission oil
tanks (B). If the oil is below this level, proceed to step #3.

3. Before removing the tank cap (C), make sure that the
area around the tank cap and fill neck of the tank is free
of dust, dirt, and other debris. Remove the tank caps.
4. Add oil up to the "FULL COLD" mark.
5. Re-install the tank cap.
6. After adding oil to the tanks, it may be necessary to purge
air from the hydraulic system. If the unit is not driving
properly perform the Purging the Air from the Hydraulic
System procedure.
Purging the Air from the Hydraulic
System
Due to the effects air has on efficiency in hydraulic drive
systems, it is critical that it be purged from the system.
These purge procedures should be implemented any time a
hydraulic system has been opened to facilitate maintenance
or any additional oil has been added to the system.
The resulting symptoms of air in the hydraulic system may be:
• Noisy operation.
• Lack of power or drive after short term operation.
• High operation temperature and excessive expansion of
oil.
Before starting, make sure the transaxles/transmissions are
at the proper oil levels. If it is not, fill to the specifications
outlined in the Check / Fill Transmission Oil Level procedure.
Purging Air from the Hydraulic System:
1. Chock the front wheels to prevent the machine from
rolling. Raise the rear of the machine so that the vehicle’s
rear tires do not contact the ground. Position jack stands
under the rear bumper of the machine to secure it.
2. Open the transaxle’s bypass valves (see Pushing the
Rider by Hand for the location and function of the bypass
valves), start the engine, release the parking brake, and
slowly move the zero-turn rider’s ground speed control
levers in both forward and reverse directions (5 to 6
