OPERATING INSTRUCTIONS
STARTING/STOPPING ENGINE
1.
Ensure parking brake is set, PTO lever is in OFF
position (Fig. 18), and lift lever is in TRANSPORT or
FLOAT position (Fig. 17). Remove foot from traction
pedal and insure it is in neutral.
2.
Move throttle control (Fig. 18) to1/4–1/3 open
position.
3.
To start engine, move choke lever (Fig. 18) fully
forward.
4.
Insert key into ignition switch (Fig. 18) and rotate it
clockwise to START position. Hold key in START
position for a few seconds to energize ignition system.
Release key immediately when engine starts and
regulate choke to keep engine running smoothly.
IMPORTANT: To prevent overheating the starter
motor, do not engage starter longer than 15
seconds. After 15 seconds of continuous cranking,
wait 10 to 15 seconds before engaging starter
motor again. To prevent a short in the ignition
system, use only one key in the switch. If keys are
on a ring, one of the keys could contact pin on top
of temperature gauge resulting in a short.
5.
When engine is started for the first time, or after
overhaul of the engine, transmission or axle, operate
the machine in forward and reverse for one or two
minutes. Also operate the lift lever and PTO lever to
assure proper operation of all parts. Turn steering wheel
to the left and right to check steering response. Then
shut engine off and check for oil leaks, loose parts, and
any other noticeable difficulties.
CAUTION
Shut engine off and wait for all moving parts to
stop before checking for oil leaks, loose parts,
or other difficulties.
6.
To stop engine, move throttle control backward to
1/4–1/3 position, move PTO lever to OFF position and
rotate ignition key to OFF. Remove key from switch to
prevent accidental starting.
CHECKING INTERLOCK SWITCHES
The machine has interlock switches in the electrical
system. These switches are designed to stop the
engine when operator gets off the seat while either the
PTO lever is engaged or traction pedal is depressed.
However, operator may get off the seat while engine is
running. Although engine will continue to run if PTO
lever is disengaged and traction pedal is released, it is
strongly recommended that the engine be stopped
before dismounting from the seat. Also, engine will stop
if traction pedal is depressed when parking brake is
engaged.
Do not disconnect the interlock switches.
Check operation of switches daily to assure
interlock system is operating correctly. If a
switch is malfunctioning, replace it before op-
erating the machine. To ensure maximum
safety, replace all switches after every two
years or 1000 hours, whichever comes first.
CAUTION
To check operation of interlock switches:
1.
Drive the machine slowly to a large, relatively open
area. Lower cutting unit, stop the engine and apply
parking brake.
2.
Sit on seat. Move PTO lever to ON position. With
the traction pedal in neutral position, try to start the
engine. The engine should not crank. If the engine
cranks, there is a malfunction in the interlock system
that should be corrected before beginning operation.
3. Sit on seat. Move PTO lever to OFF and depress the
traction pedal. Try to start the engine. The engine
should not crank. If the engine cranks, there is a
malfunction in the interlock system that should be
corrected before beginning operation.
WARNING
Do not operate machine without implement
unless the PTO driveshaft is also removed.
4.
Sit on seat and start the engine. Raise off the seat
and move the PTO lever to ON. The engine should stop
within 2-3 seconds. If the engine does not stop, there is
a malfunction in the interlock system that should be
corrected before beginning operation.
5. Sit on seat. With parking brake engaged, engine
running and PTO lever disengaged, depress the
traction pedal. The engine should stop within 2-3
seconds. If the engine does not stop, there is a
malfunction in the interlock system that should be
corrected before beginning operation.
PUSHING OR TOWING TRACTION UNIT
In an emergency, the traction unit can be pushed or
towed for a very short distance. However, Toro does not
recommend this as standard procedure.
IMPORTANT: Do no push or tow the traction unit
faster than 2 to 3 mph (3 to 4.8 km/hr) because
transmission may be damaged. If traction unit must
be moved a considerable distance, transport it on a
truck or trailer. Whenever traction unit is pushed or
towed, by–pass valve must be open.
