Troy-Bilt 8 HP - Manual (Page 19)

OPERATION OF TILLER
using gasohol, refer to the Briggs
& Stratton Operating and Mainte­
nance Instructions booklet for
specific cautions and recommen­
dations for this type of fuel.
(e) For
8
HP Kohler Engines: use
fresh, clean, unleaded regular auto­
motive gasoline with a pump sticker
octane rating of 87 or higher.
(Leaded “Regular” grade gasoline
is an acceptable substitute). The
fuel tank capacity is
Vk
gallons.
(f) Replace the fuel cap securely
before starting the engine.
A DANGER
GASOLINE IS HIGHLY FLAMMABLE
AND ITS VAPORS ARE EXPLOSIVE.
FOLLOW THESE SAFETY PRAC­
TICES TO PREVENT INJURY FROM
FIRE OR EXPLOSION!
• Never fill tank when engine is
running or still hot from operation.
Allow engine and muffler to cool at
least
2
minutes before refueling.
• Do not allow open flames,
sparks, matches or smoking in the
area.
• Fill fuel tank outdoors in a well-
ventilated area. Wipe up any spills
and move tiller away from gasoline
fumes before starting engine.
• Use only an approved gasoline
container and store safely out of
reach of children.
• Store gasoline and tiller in a
well-ventilated area. Do not store
where vapors may reach an open
flame or spark, or where ignition
sources are present (such as hot
water and space heaters, furnaces,
clothes dryers, stoves, electric
motors, etc.)
• Allow engine to cool before stor­
ing in any enclosures.
• Never bring a gasoline can near
the battery posts on electric start
model tillers. A short circuit caused
by touching the positive (+) post
and any metal could cause an ex­
plosion of the gasoline or of bat­
tery gases.
Test operation of Forward
Interlock Safety System
The Forward Interlock Safety
System consists of an electrical
grounding system that connects
the two Forward Interlock Levers
on the handlebars to the ignition
system of the engine. One or both
of the Forward Interlock Levers
must be kept squeezed against the
handlebar grip(s) whenever the
Wheels/Tines/PTO Drive Lever is
engaged in “FORWARD”. If you
release BOTH interlock levers be­
fore first moving the Wheels/Tines/
PTO Drive Lever to “NEUTRAL”, the
interlock 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”.
Because the interlock system is
an electrical/mechanical device, it
is subject to wear or possible fail­
ure. Therefore, the interlock sys­
tem should be checked for proper
operation each time the tiller or
PTO Power Unit is used.
^ DANGER
The Forward Interlock Safety Sys­
tem is designed for your safety.
Never attempt to disconnect or to
otherwise defeat the purpose of
this system. If the interlock system
fails to operate properly, immedi­
ately contact the TROY-BILT Tiller
Technical Service Department. Do
not operate the tiller or PTO Power
Unit until the system has been re­
paired and is functioning properly.
Always test the system prior to
each use.
How to check the interlock system:
1. Move the machine outdoors and
park it on level ground. Make sure
the area around you is clear of any
obstacles.
2. Check to make sure that the
Forward Interlock Wire Harness
plug at the bottom of the handle­
bars is firmly connected to the wire
harness receptacle located on the
top, right side of the transmission.
See Photo 3-2.
3. Place the Wheel Speed Lever in
“SLOW” and the Tines/PTO Clutch
Lever in “DISENGAGE”.
4. Start the engine as described
on Pages 18-19. Set the throttle
lever in a “SLOW” running position
and ailow the engine to warm up.
5. Squeeze one of the Forward
Interlock Levers against the handle­
bar grip and then push the Wheels/
Tines/PTO Drive Lever all the way
down to “FORWARD”. See Photo
3-3. As the tiller starts to move
r
3-2: Check for good connection be­
tween plug and receptacle of Forward
Interlock Safety System.
3-3: Squeeze one Forward Interlock
Lever and then move Wheels/Tines/
PTO Drive Lever down to “FORWARD”.
