Checking The Operation Of The Interlock Switches; Towing The Traction Unit - Toro 03422 Operator's Manual

6. When a steady stream of fuel flows out of the transfer
pump screw, tighten the screw, retaining the angle of the
fitting before loosening (Fig. 36).
7. Loosen the injection pump inlet screw on the front of
the engine (Fig. 36).
8. Pump the priming lever (Fig. 36) until a steady stream
of fuel flows out of the injection pump inlet screw, then
tighten the screw. Do not over-tighten the screw as
damage may occur.
9. Start the engine. If it still does not run smoothly after
several minutes, crack each injector nut until fuel (no
bubbles) comes out.

Checking the Operation of the
Interlock Switches
Caution
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
Do not tamper with the interlock switches.
Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
Replace switches every two years regardless of
whether they are operating properly or not.

1. Be sure that the parking brake is set and all bystanders
are away from the area of operation. Keep hands and
feet away from the cutting units.
2. With the operator off of the seat, the backlap knob
rotated counterclockwise, the traction pedal in neutral,
and the reel switch in the OFF position, the engine
should start. If either the traction pedal is depressed or
the reel switch is turned ON, with the operator off of the
seat, the engine should stop. Correct the problem if it is
not operating properly.
3. With the engine running, the operator off of the seat,
and the backlap knob rotated clockwise, the engine
should not stop when the reel switch is turned ON.
Correct the problem if it is not operating properly.
4. With the operator on the seat, the engine running, and
the reel switch in the ON position, the dash indicator
light should be glowing and the reel motors turning
when the lift cylinder is fully retracted. As the lift
cylinder is extended, the light should go out and the reel
motors should stop turning. Correct the problem if it is
not operating properly.
5. With the operator on the seat, the engine must not start
with either the reel switch engaged or the traction
control engaged. Correct the problem if it is not
operating properly.

Towing the Traction Unit

In case of an emergency, the machine can be towed for a
short distance. However, we do not recommend this as a
standard procedure.
Important
Do not tow the machine faster than 2–3
MPH because the drive system may become damaged. If
the machine must be moved a considerable distance,
transport it on a truck or trailer.
1. Locate the bypass valve on the pump (Fig. 37) and
rotate it 90 (the bypass valve lever should be
horizontal when it is open).
