CHECKFOROILLEAKS
Beforeeachuse, checkyour tiller for
signs of an oil leak- usually a dirty, oily
accumulation either on the unit or on the
floor where it has beenparked.
A little seepagearound a cover or oil seal
is usually not a causefor alarm. However,
ifthe oil drips overnight then immediate
attention is neededas ignoring a leakcan
result in severetransmission damage.
If a cover is leaking,try tightening any
loosescrews or bolts. Ifthe fasteners are
tight, a new gasket or oil seal maybe
required. If the leak isfrom around a
shaft and oil seal,the oil seal probably
needsto be replaced. Seeyour autho-
rizeddealeror contact the factory for
service or advice.
