Qperation
Test
Operation
of
Forward
Interlock
Safety
System
The
Forward
Interlock
Safety
System
is
designed
to
shut
the
tiller
engine
off
immediately
if
you loose
control
of
the
tiller
and
cannot
stop
forward
motion
by
moving
the
Wheelsffines/PTO
Drive
Lever
into
NEUTRAL.
Simply, it is an electrical
grounding system that connects the
two Forward Interlock Levers on
the handlebars to the engine's igni-
tion system. Either one (or both)
of
the Forward Interlock Levers
must be kept squeezed against the
handlebar gripes) whenever the
Wheels/ Tines/ PTO Drive Lever
is
engaged in FORWARD.
If
you
release
both
the
Forward
Interlock Lever(s) before first
moving the
WheelsffinesIPTO
Drive Lever to NEUTRAL, the in-
terlock system
will
ground
out
the
engine's ignition system
and
stop
the engine. (The interlock system
also prevents the engine from start-
ing
if
the Wheels/ Tines/PTO Drive
Lever
is
engaged in FORWARD.)
This system has an electro-me-
chanical design, and so
is
subject
to
normal wear and possible malfunc-
tion. As such, it must be checked for
proper operation before you use the
tiller or PTO power unit each time.
How
to
Check
the
Interlock
System:
1.
Move tiller outside on level
ground. Remove any obstacles.
2.
Check that the Forward Interlock
wire harness plug at the bottom
of
the handlebars is firmly connected
to
the receptacle on the top, right side
of
the transmission. See Photo 4-2.

Interlock
Safety
System
must
be
securely
connected.
3. Move Wheel Speed Lever
to
SLOW position and move Tines/
PTO Clutch Lever
to
DISENGAGE.
4.
Start engine
as
described later
in
this section. Set engine throttle lever
to
SLOW, and let engine wann
up.
5. Squeeze and hold just one
of
the
Forward Interlock Levers against the
handlebar grip while moving the
Wheels/ Tines/ PTO Drive Lever
down
to
FORWARD. (See Photo
4-3). As the tiller moves forward,
release the Forward Interlock Lever
briefly. The engine should start
to
stall out
if
the interlock system
is
working properly.
If
it does start
to
stall, quickly squeeze the lever up
against the handlebar grip, and then
return the Wheels/ Tines/ PTO Drive
Lever
to
NEUTRAL. Repeat this
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 offwhen either Forward
Interlock lever is released, shut the
engine off, remove the key (ifelec-
tric start), and
do
not
operate
the
tiller
or
PTO
power
unit
until the
system
has
been
repaired
and
is
functioning properly.
IMPORTANT
- To avoid possible
damage
to the
Forward
Interlock
Safety system, do
not
use high-
pressure
sprays
near
the wire
har-
ness receptacle
or
neutral
plunger
assembly.
DANGER

Forward
Interlock
Safety
System
is designed for

safety.
Do
not
dis-
connect

defeat
the
purpose
of
the
system.
If
the
