OPERATING MACHINE
Testing Safety Systems
NOTE: Your Yard Tractor is equipped with a
ELECTRONIC SAFETY INTERLOCK. Engine will not
start unless: • Operator is on seat; • PTO switch is
DISENGAGED; • Brake pedal is depressed OR
parking brake is set.
Use the following checkout procedure to check for
normal operation of tractor.
If there is a malfunction during one of these procedures,
DO NOT operate tractor. (See your Sabre Service
Center for service.)
Perform these tests in a clear open area. Keep
bystanders away
.
Test 1
Check operation of indicator lights:
• Turn key to RUN position.
• Pull PTO switch (B) up to ENGAGE.
• LOOK: Indicator light (A) must light.
• If indicator does not light, see Replacing Indicator
Light Bulb in Service – Electrical section.
• If new indicator bulb does not light or no indicators
work, see your Sabre Service Center for service.
Test 2
1. Operator on seat.
2. UNLOCK the park brake.
3. Push PTO switch (A) down to DISENGAGE.

CAUTION: Engine exhaust fumes can cause
sickness or death.
If it is necessary to run an engine in an
enclosed area, remove the exhaust fumes
from the area with an exhaust pipe extension.
If you do not have an exhaust pipe extension,
