Checking the Interlock System
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. Make sure that all bystanders are away from the area of
operation. Keep hands and feet away from the cutting
units.
2. While sitting on the seat, the engine must not start with
either the deck switch engaged or the traction pedal
engaged. Correct the problem if it is not operating
properly.
3. While sitting on the seat, put the traction pedal in
neutral, the parking brake off, and the deck switch in
the Off position. The engine should start. Rise from the
seat and slowly depress the traction pedal, the engine
should stop in one to three seconds. Correct problem if
it is not operating properly.
Note: The machine is equipped with an interlock switch on
the parking brake. The engine will stop if the traction pedal
is depressed with the parking brake engaged.
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 (3–4 km/h) 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. 21) and
rotate it 90°.
