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- based grease.

WARNING

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

To check the transmission:

1. Stop the engine, let it cool and discon-

nect the spark plug wire.

*For commercial use, log hours of operation to determine proper maintenance intervals.

(1) Check after first 5 hours of use.

(2) Service more frequently when used in dusty areas.

(3)Item should be serviced by your servicing dealer, unless you have the proper tools and are mechanically proficient.

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 11) from the transmission.

Figure 11: Transmission lubricant check and fill locations.

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 (D, Figure 11) of a standard grease gun 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 lubri- cant.

•Throttle/Tines Control Lever Cable: Squeeze the lever closed and spray a lu- bricant 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/Electrical Connections

Before each use, check that all hardware is tight and that the On/Off Switch wire connections are secure. Also check that the switch wiring is in good condition.
