•Removetines and clean tine shafts (C, Figure 5-1). Inspect for rust, rough spots or burrs (especiallyaroundholes). File or sand smooth and coat ends of shaft with grease.

•Oil the threads on the handlebarheight adjustment handle(D, Figure 5-1).

•Oilthe outer casings of the enginethrot- tle cable andthe wheel gearcable (E, Figure5-1). Allow oil to soak inandthen wipe off any excess.

•Oil the various pivot points (F,Figure 5- 2) on the shifting mechanism, the han- dlebar,and the idler arms (do not allow oil on the belts or pulleys).

lation either on the unit or onthe floor where it has been parked.

A little seepagearound a cover or oil seal is usually not a causefor alarm. However, if the oil drips overnight, then immediate attention is needed--ignoring a leak can result in severetransmission damage.

If a cover leaks, try tightening any loose screws or bolts. If the fastenersaretight, a new gasket or oil seal may be required. If the leak is from arounda shaft and oil seal, the oil seal probably needsto be replaced. Seeyour authorized dealeror contact the factory for service or advice.

IMPORTANT:Neveroperatethe tiller if the transmission is low on oil. Checkthe oil

level after every30 hours of operation and wheneverthere is any oil leakage.

CheckHardware

Checkthe unit for loose or missing hard- wareafter every10 operatinghours. Loose or missing hardwarecan leadto equip-

ment failure, poor performance, or oil leaks.

Besure to check the three end cap mount- ing screws locatedat the rear of the trans-

mission (Figure 5-3). Lift the tine flap to service those screws.

Tiller Lubrication

Proper lubrication of the tiller is an essen- tial part of your maintenanceprogram. Af- ter every 10operating hours, oil or grease

the lubrication points shown in Figures5- 1 and 5-2 and described below.

Usegeneral purpose lubricating oil (#30 weight motor oil is suitable) and a general purpose grease (metal lubricant is pre- ferred, if available).

•Removewheelsandcleanwheelshaft (A, Figure 5-1). Apply a thin coating of greaseto shaft before reinstalling wheels.

•Greaseback, front and sides of depth regulator lever (B, Figure 5-1).

Check Tire Air Pressure

Checktheair pressure inboth tires. Deflate or inflate both tires evenlyto between 15 and 20 PSi (pounds per square inch). Be sure that both tires haveequalair pressure or the unit will pull to one side.

Check For Oil Leaks

Beforeeach use,checkyour tiller for signs of an oil leak--usually adirty, oily accumu-

Transmission Gear Oil Service

Checkthe transmission gear oil level after every 30 hours of operation or whenever you notice any oil leak. Operatingthe tiller when the transmission is low on oil can re- sult in severe damage.
