TILLER LUBRICATION

After every 10 Operatinghours, oil or grease the lubrication points shown in Figure5-1 and described belOW,

Useclean lubricating oil (#30weight motor oil is suitable) and clean generalpurpose grease(greasecontaining a metallubricant is preferred, if available).

•Removethe wheels,cleanthe wheel shaft (A, Fig. 5-1) and apply a thin coating of greaseto the wheel shaft,

•Greasethe back, front and sides of the depth regulator lever (B, Fig. 5-1).

•Removethe tines andcleanthe tine shaft (C, Fig. 5-1). Use a file or sandpaperto gently remove any rust, burrs or rough spots (especiallyaround holes in shaft). Apply greaseto ends of shaft before install- ing tines,

•Oilthe threads onthe handlebarheight adjustment screws andthe handlebar

attaching screws (D, Fig.5-1).

If a cover is leaking,check for loose screws. If the screws aretight, a new gasket or oi! seal may be required.

If the leak is from around a shaft and oil seal, the oil seal probably needsto be replaced. Seeyour authorizeddealeror contact the factory for service or advice.

IMPORTANT:Neveroperate the tiller if the transmission is low on oil. Check the oil level after every30 hours of operation and wheneverthere is any oil leakage.

CHECKHARDWARE

Checkfor loose or missing hardwareaf- ter every 10 operatinghours and tighten or replace(as needed)before reusing tiller

Besureto checkthe screws underneath the tiller hoodthat securethe transmis-

sion coverandthe DepthRegulatorLever to the transmission.

Keepboth tires equally inflatedto help

TRANSMISSION

GEAROIL SERVICE

Checkthe transmission gear oil level after every 30 hours of operation or wheneveryou noticeany oil leak. Oper- ating the tiller when the transmission is low on oil can result in severedamage.

Figure5.1

CHECKFOROILLEAKS

Beforeeachuse,checkthe tiller for signs of an oil leak -- usually a dirty, oily accumu- lation either on the unit or on the floor.

Alittle seepagearound a cover or an oil seal is usually not a causefor alarm. How- ever,if the oil drips overnight, then imme- diate attention is needed. Ignoring an oil leak can result in severe transmission damage]

A.To Checkthe Transmission Gear Oil Level:

1.Checkthe gear oil level when the transmission is cool. Gearoil will

expand in warm operating temperatures andthis expansionwill provide an incor- rect oil level reading.

2.With the tiller onlevelground, pullthe Depth RegulatorLever all the way up.

3.Removethe oil fill plug (A, Fig. 5-2) from the transmission housing and look

inside the oil fill holeto locatethe main drive shaft situated below the hole.
