Testing
the Forward
Interlock
Safety System
The Forward Interlock Safety System is
designed to shut the tiller engine off
immediately if you lose control and
cannot stop moving FORWARDby
shifting the Wheels/Tines/PTODrive Lever
into NEUTRAL. When you releaseboth
Forward Interlock Levers,they send
ground to the ignition system thereby
stopping the engine. Squeezingone or
both levers up against the handlebars
enablesthe ignition system; therefore,
you must squeezeat least one lever
whenever the Wheels/Tines/PTODrive
Lever is engaged in FORWARD.
IMPORTANT: The interlock system also
prevents the engine from starting if the
Wheels/Tines/PTODrive Lever is engaged
in FORWARD.
2O
The ForwardInterlock Safety System is
designed for the operator's safety. Do
not disconnector attempt to defeat the
purpose of the system. If the system
malfunctions,immediately contactyour
local authorized dealer or the
TROY-BILT Technical Service Depart-
ment for assistance. Do not use the
tiller or the PTO power unit until the
Forward Interlock Safety System is
functioning properly. Always test the
system before using the tiller or PTO
power unit.
How to Check the Interlock System
The Forward Interlock System has an
electro-mechanical design, and so is
subject to normal wear and possible mal-
function. Checkthe system for proper
operation each time prior to using the
tiller or PTOpower unit.
Figure 4.6: Plug and receptacle of
Forward Interlock Safety System
must be securely connected.
To test the Forward Interlock System:
1. Move tiller outside to level ground.
Removeany obstacles.
2. Checkthat the Forward Interlock wire
harness plug, at the bottom of the handle-
bars (Figure4-6), is securely connected
to the receptacleon the top, right side of
the transmission.
3. Move Wheel Speed Lever (Figure 4-2)
to SLOW position and move Tines/PTO
Clutch Lever to DISENGAGE.
4. Start engine as described under
Starting and Stopping the Engine,in this
section. Set engine throttle lever to
SLOW, and let engine warm up.
5. Squeezeand holdjust one of the
Forward Interlock Levers against the
handlebar grip while moving the Wheels/
Tines/PTO Drive Lever down to
FORWARD(Figure 4-3). As the tiller
moves forward, releasethe Forward Inter-
lock Lever briefly. The engine should
start to stall out if the interlock system is
working properly. If it does start to stall,
quickly squeezethe lever up against the
handlebar grip, and then return the
Wheels/Tines/PTO Drive Lever to
NEUTRAL. Repeatthis test to check that
the engine begins to stall out when the
other Forward Interlock Lever is released.
6. If the engine does not begin to shut off
when either Forward Interlock lever is
released, shut the engine off, remove the
key (if electric start), and do not operate
the tiller or PTOpower unit until the
system has been repaired and is func-
tioning properly.
IMPORTANT: To avoid possible damage
to the Forward Interlock Safety system,
do not use high-pressure sprays near the
wire harness receptacleor neutral plunger
assembly.
Loading and Unloading the Tiller
The following provides information on
tiller loading,unloading, and requirements
before loading and unloading the tiller,
Readthe following instructions carefully
before attempting to load or unload your
tiller.
Before Loading or Unloading the
Tiller
• Ramps must be strong enough to
support the combined weight of the tiller
and handlers. They should provide good
traction to prevent slipping; they should
have side rails to guide the tiller along
the ramps; and they should have a
locking device to secure them to the
vehicle.
• Handlers should wear sturdy footwear
that will help to prevent slipping.
