Maintenance

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.

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.

WARNING

Before tipping engine or equipment to service transmission, drain fuel from tank by running engine until fuel tank is empty.

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.

Carburetor Adjustment

WARNING

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.
