To stop the engine, move the throttle control backward to
the SLOW position, move the PTO lever to the OFF posi-
tion, and turn the ignition key to OFF. Remove the key
from the switch to prevent accidental starting.
PRIMING THE FUEL SYSTEM (Fig. 10)
IMPORTANT: The fuel system may need to be primed
when a new engine is started for the first time, if it runs out
of fuel or if maintenance is performed on the fuel system.
1.
Unlatch and raise the hood.
2.
Insert a 3/16" hose over the bleed screw and run other end
into a container to catch the fuel.
3.
Loosen the fuel filter/water separator bleed screw (Fig.
10) a few turns. Pump the priming plunger until a steady
stream of fuel comes out of the hole in the bleed screw.
When fuel stops foaming, tighten the bleed screw during
the downstroke of the priming plunger. Wipe up any
spilled fuel.
4.
Pump the priming plunger until resistance is felt. Try to
start the engine. If the engine does not start, repeat step 3.
CHECKING INTERLOCK SWITCHES
The machine has interlock switches in the electrical system.
These switches are designed to stop the engine when the oper-
ator leaves the seat when the traction pedal is depressed.
However, the operator may leave the seat while the engine is
running. Although the engine will continue to run if the PTO
lever is disengaged and the traction pedal is released, it is
strongly recommended that the engine be stopped before dis-
mounting from the seat.
To check operation of the interlock switches:
1. Drive the machine slowly to a large, relatively open area.
Lower the cutting unit, stop the engine and apply the
