(See Section 7.10)

4.4 STARTING THE ENGINE

DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause a “runaway” engine condition
that could result in engine damage and/or personal
injury.

1. Before initial start or after running out of fuel, you

must prime the fuel pump located on the right side of
the engine. Pump the primer pump until it can no
longer be depressed.

2. Be sure the fuel shutoff valve, located behind the

operator's seat, is completely open. (See Section 7.5
Page 30)

3. Sit in the operator’s seat, fasten seat belt and place

the steering control levers in the neutral position.

4. Engage the parking brake.

5. Place the PTO switch in the disengaged position.

CAUTION:

speed.

7. Turn the ignition key to the on position until the

yellow indicator for the glow plugs goes out. Then
turn the ignition key to the START position and
release the key as soon as the engine starts. Do not
hold the key in the START position for more than 15
seconds at a time. Allow at least 60 seconds
between each cranking attempt to prevent
overheating of the starter motor. Prolonged cranking
can damage the starter motor and shorten battery
life.

8. Allow engine to warm before operating the mower.

4.5 GROUND TRAVEL AND STEERING

-IMPORTANT-

If you are not familiar with the operation of a
machine with lever steering and/or hydrostatic
transmissions, the steering and ground speed
operations should be learned and practiced in
an open area, away from buildings, fences, or
obstructions. Practice until you are comfortable
with the handling of the machine before
attempting to mow. Learn the operation on flat
ground before operating on slopes.

-IMPORTANT-

Start practicing with a slow engine speed and
slow forward travel.

Learn to feather the steering controls to obtain
a smooth operating action.

Practice operating the mower until you are
comfortable with the controls before proceeding
to mow.

Forward Travel

To travel forward with the mower, disengage the parking
brake and slowly push the steering control levers forward
an equal distance. The further the steering control levers
are pushed forward, the greater the forward speed will
be. To increase the speed, push the steering control
levers further forward and to decrease the speed, pull the
steering control levers back.
