Priming the Fuel System

Prime the fuel system before starting the engine for
the first time, after running out of fuel, or after fuel
system maintenance (e.g., draining the filter/water
separator, replacing a fuel hose).
To prime the fuel system, perform the following steps:
1. Ensure that fuel is in the fuel tank.
2. Perform the following steps to prime the filter
and the lines to the high pressure pump to
prevent wear or damage to the pump:
A. Cycle the key to the O
20 seconds.
B. Cycle the key to the O
40 seconds.
Note:
This allows the ECU to power down.
C. Cycle the key to the O
20 seconds.
D. Inspect for leaks around the filter and hoses.
Important:
Do not use the engine starter motor to
crank the engine to prime the fuel system.

Maintenance

Electrical System Safety

•
Disconnect the battery before repairing the
machine. Disconnect the negative terminal first
and the positive last. Connect the positive terminal
first and the negative last.
•
Charge the battery in an open, well-ventilated
area, away from sparks and flames. Unplug the
charger before connecting or disconnecting the
battery. Wear protective clothing and use insulated
tools.
Checking the Battery
Condition
Service Interval: Every 50 hours
Important:
Before welding on the machine,
disconnect the negative cable from the battery to
prevent damage to the electrical system. Also,
you must disconnect the engine, InfoCenter,
and machine controllers before welding on the
machine.
Note:
Keep the terminals and the entire battery case
clean, because a dirty battery discharges slowly. To
clean the battery, wash the entire case with a solution
of baking soda and water. Rinse with clear water.
Coat the battery posts and cable connectors with
Grafo 112X (skin-over) grease (Toro Part No. 505-47)
or petroleum jelly to prevent corrosion.
