danger
Gasoline is highly flammable and its vapors are explo-
sive. To prevent personal injury or property damage:
Store gasoline only in approved containers, in well
ventilated, unoccupied buildings, away from sparks or
flames. Do not fill the fuel tank while the engine is hot
or running. Spilled fuel could ignite if it comes in contact
with hot parts or sparks from ignition. Do not start the
engine near spilled fuel. Never use gasoline as a cleaning
agent.
imPorTanT
Do not attempt to start the engine at this time. Wait until
you have read the complete starting instructions in the
Operation Section of this manual.
2.7.2 filling The fuel Tank
For best results use only clean, fresh, unleaded gasoline
with a pump octane rating of 86 or higher or a research
octane rating of 91 or higher.
purchase gasoline in small quantities and store in
clean, approved containers. DO NOT mIx OIL WITH
GASOLINE.
ethanol
Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline
by volume) is an approved fuel. Other gasoline/alcohol
blends are not approved.
mTbe
methyl Tertiary Butyl Ether (mTBE) and unleaded gasoline
blends (up to a maximum of 15% mTBE by volume) are
an approved fuel for engine models. Other gasoline/ether
blends are not approved.
methanol
methanol (up to a maximum of 5% volume) is an approved
fuel. methanol blends must contain cosolvents and
corrosion inhibitors to protect the fuel system. Gasoline
containing more than 5% methanol may cause engine
problems.
To add gasoline
Stop engine, wait for all parts to stop moving and 1.
disconnect spark plug wire. Remove key from key
switch. Allow the engine and muffler to cool for at least
three minutes.
Clean area around fuel fill cap and remove cap.
2.
using a clean funnel, fill fuel tank to 1/2" below bottom 3.
of filler neck to provide space for any fuel expansion.
Install fuel fill cap securely and wipe up any spilled
gasoline.

Figure 17, shortening the driveline
Attach chipper to tractor with three-point hitch. Adjust 1.
the chipper up and down to find the shortest distance
between the chipper rotor shaft and tractor pTO.
pull the driveline into two pieces. Connect one end to the
2.
tractor pTO and the other end to the chipper rotor shaft.
Line up the two halves parallel to each other. If the shaft
of one half extends past the end shield of the other half
as seen in the illustration below, you will need to shorten
the driveline. if your driveline is not too long, slide
the two ends together and skip to step 7.
measure the distance from the end of the driveline tube
3.
to the bottom of the end shield of the other driveline half
(dimension “A” in Figure 17). measure and mark the
driveline tube 1-9/16” inward from dimension “A.”
Cut the shield tube in the marked position.
4.
using the cut piece of shield tube as your measure- 5.
ment, place the cut piece against the end of the shaft.
mark and cut the shaft.
Repeat step 5 for the other half of the driveline, file both
6.
shaft ends, and slide the two halves back together.
The longest distance between the tractor pTO and
7.
chipper rotor shaft must also be checked. If the longest
distance exceeds 24.5", contact your dealer to obtain
a longer pTO shaft.
When you have confirmed that your pTO shaft is the
8.
proper length, connect the driveline to the chipper rotor
shaft using key stock and two set screws contained in
the owner’s kit.
Connect the opposite end of the pTO shaft to the tractor.
