EQUIPMENT MAINTENANCE
Transmission Maintenance
The transmission was factory-lubricated with grease and
should not require any further lubrication.
However, you should check for sufficient lubrication after
the initial five (5) hours of operation, and every twenty-
five (25) operating hours thereafter. If needed, use a
high-quality, automotive-grade petroleum-base grease.
A WARNING
Before tipping engine or equipment to service
transmission, drain fuel from tank by running en­
gine until fuel tank is empty.
To check the transmission;
• Stop the engine, let it cool, and disconnect the
spark plug wire before proceeding.
• Place the machine down on its left side so the right
end of the tine shaft points up.
• Remove the ring lock pin and both right-side tines.
(See “Tine Removal” in this section.)
Figure 16: Transmission housing iubricant check and fiil
iocations (A,B,C). Refer to text for instructions.
• Clean the transmission housing thoroughly so dirt
and debris can not enter the transmission.
• Remove all three threaded plugs (Figure 16) from
the transmission with a hex wrench. Lubricant should
be visible in the top two holes. If so, replace all plugs.
If lubricant is needed, proceed as follows.
To lubricate the transmission:
• Place the nozzle of a standard grease gun up
against the rim of the middle hole. Push the nozzle
firmly against the opening.
• Apply grease until it begins to come out of the bot­
tom hole. Replace the bottom plug securely. Then
apply grease to the top fill hole. Add until it begins to
come out of the middle hole. Reinstall the plugs in
the middle and top holes.
• Reinstall the right-side tines. Before reinstalling the
tines, use a fine grade sandpaper to clean any rust off
the shaft. Then coat the tine shaft with a few drops of
oil to make future tine removal easier.
Other Lubrication Locations
• Handlebar Ratchet Slots-
Spray occasionally with a silicone lubricant. The ratchet
slots and mating teeth will align more quickly and easily
with lubrication.
• Engine Throttle Lever Cable-
Squeeze the lever closed and spray a lubricant (like
WD40) into the cable area.
• Tine Shaft-
After each use, remove all tine sections, clean tine shaft
with sandpaper and apply a light coat of oil to the tine
shaft. This will make future tine removal easier.
Hardware/Eiectricai Connections
Before each use, examine hardware and electrical con­
nections, verifying hardware is tight, wire connections
are secure, and wire sheathing is in good condition.
