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.

Note (1) – After first five (5) hours of use.

Note (2) – Clean daily when conditions are extremely dusty or dirty.

Note (3) – Spark plug may be checked annually or every 100 operating hours.

EQUIPMENT MAINTENANCE

Transmission Maintenance

The transmission was lubricated with grease at the factory and it should not require any further lubrication.

However, you should check the lubricant level after the first five

(5)hours of operation 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:

•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 right-side tines (see Tine Removal and Installa- tion in this Section).

•Clean the transmission housing to prevent dirt and debris from entering the transmission.

•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:

•Place the nozzle of a standard grease gun firmly against the rim of the middle hole (B, Figure 14) 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.

•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 sili- cone type lubricant.

•Engine Throttle Lever Cable: Squeeze the lever closed and spray a lubricant (such as WD40) 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 tight- ened securely.

ENGINE MAINTENANCE

Engine Lubrication

The engine is a two-cycle engine. Lubrication is provided by mixing two-cycle oil with unleaded regular gasoline as described in the Assembly Section. Attempting to operate the engine on gasoline alone will cause the engine to overheat and seize up.
