EQUIPMENT MAINTENANCE
Transmission Maintenance
The transmission was lubricated at the
factory and should not require any further
lubrication.
However, you should check the lubricant
level after the first five (5) hours of opera-
tion and every twenty-five (25) operating
hours thereafter. If needed, use a high-
quality, automotive-grade petroleum-base
grease.
To check the transmission:
1. Stop the engine, let it cool and discon-
nect the spark plug wire.
2. Place the machine down on its left side
so the right end of the tine shaft faces up.
3. Remove the right-side tines (see Tine
Removal and Installation in this Section).
4. Clean the transmission housing.
5. Remove the three threaded plugs (A, B
and C, Figure 14) from the transmission.
Lubricant should be visible in the top two
holes (B and C). If so, replace all three
plugs. If lubricant is needed, proceed as
follows.
To lubricate the transmission:
1. Place the nozzle of a standard grease
gun (D, Figure 14) firmly against the rim
of the middle hole (B) and add grease
until it begins to seep from the bottom
hole (A). Reinstall the plug in the bottom
hole (A). Next apply grease to the top fill
hole (C) until it begins to seep from the
middle hole (B). Reinstall the plugs in the
middle (B) and top (C) holes.
2. Before reinstalling the tines, use a fine
grade sandpaper to clean any rust off the
tine shaft. Apply a few drops of oil to the
tine shaft to make future tine removal
easier.
Other Lubrication Points
• Handlebar Adjustment Knobs: Spray
occasionally with a silicone type
lubricant.
• Throttle/Tines Lever Cable: Squeeze the
lever closed and spray a lubricant into
the cable area.
• Tine Shaft: After each use, remove the
tines, clean the tine shaft with sandpaper
and apply a light coat of oil to the tine
shaft.
Hardware
Before each use, check that all hardware
is in place and tightened securely.
ENGINE MAINTENANCE
Engine Lubrication
The engine is a two-cycle engine. Lubri-
cation is provided by mixing two-cycle oil
with unleaded regular gasoline as de-
scribed in the Assembly Section. At-
tempting to operate the engine on gaso-
line alone will cause the engine to over-
heat and seize up.
Engine Air Filter
It is extremely important that air filter ser-
vice be performed according to the main-
tenance schedule. Refer to the separate
Engine Owner’s Manual for inspection and
cleaning instructions.
IMPORTANT: Never run engine without air
filter assembly properly installed.

Before tipping engine or equipment to
service transmission, drain fuel from
tank by running engine until fuel tank is
empty.
WARNING
Before inspecting, cleaning or servicing
the machine, shut off engine, let all
moving parts come to a complete stop,
disconnect the spark plug wire and move
the wire away from the spark plug.
Failure to follow these instructions can
result in personal injury or property
damage.
WARNING
Maintenance

Section
Do not tamper with the engine governor
screw which is factory-set for the proper
engine speed. Overspeeding the engine
beyond the factory high speed setting
can be dangerous and will void the
engine warranty. Authorized service
shall be sought if a problem exists.
