TILLER LUBRICATION

Afterevery10operatinghours,oil or greasethelubricationpointsshownin Figure5-1 anddescribe 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).

If a cover is leaking, checkfor 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.

CHECKFOROILLEAKS

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

A little 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]

prevent machinefrom pulling to one side.

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.

A.To Checkthe Transmission Gear Oil Level:

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

expand in warm operating temperatures andthis expansion will 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 locate the main drive shaft situated below the hole.
