Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove the key from the keyswitch on units so equipped.

Failure to follow these instructionscan result in serious personal injury or property damage.

CHECKFOROIL LEAKS

Beforeeach use, check your tiller for signs of an oil leak - usually a dirty, oily accumulation either on the unit or on the floor where it has beenparked.

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

If a cover is leaking,try tightening any loose screws or bolts. Ifthe fasteners are tight, a new gasket or oil seal may be required. If the leak is from around a shaft and oil seal,the oil seal probably needsto be replaced. Seeyour autho- rized dealeror contact the factory for service or advice.

IMPORTANT:Neveroperatethe tiller if the transmission is low on oil. Checkthe oil levelafter every 30 hours of operation and wheneverthere is any oil leakage.

TRANSMISSIONGEAR01LSERVICE

Checkthe transmission gear oil level after every 30 hours of operation or whenever you notice any oil leak. Operating the tiller when the transmission is low on oil

can result in severedamage.

A. To CheckTransmissionGear Oil Level:

1.Checkthe gear oil level when the trans- mission is cool. Gearoil will expand in warm operating temperaturesand this expansion will provide an incorrect oil level reading.

2.To check the gear oil level (and to add oil, if necessary), refer to "STEP 5: Check GearOil Level in Transmission" in Section

2of this manual.

B. To Drain and Refill the Transmission:

The transmission gear oil does not need to be changed unless it has beencontami- nated with dirt, sand or metal particles.

1.Prop up the left side of the unit so that it will be securely supported when the left side wheel is removed. Removethe left side wheel by removing the wheel mount- ng hardware.

2.Unscrewthe plastic gear oil fill plug from the top of the transmission.

3.Placea clean pan below the transmis-

sion drain plug (see Figure5-3) and removethe drain plug. The oil will start flowing out of the drain hole (it may flow slowly, especially in cold temperatures).

4.Removethe transmission gearoil level check plug that is locateda few inches abovethe left side wheel shaft.

5.When the oil stops flowing, tilt the transmission forward to drain oil from the rear of the transmission.

6.After draining the oil, clean the threads of the drain plug, apply a non-hardening removablegasket sealantto the threads, and securely reinstall the drain plug.

7.Using a clean funnel, slowly add SAE

140or SAE85W-140 weight gear oil

(with an API rating of GL-4 only) to the transmission. The transmission holds

approximately 3-1/4 pints (52-54 ounces). Tilt the tiller slightly backwards to makesure the gear oil reachesthe rear (tine) end of the transmission. Step

adding gear oil when it begins to flow from the oil level check hole on the side of

the transmission.

8.Securely reinstallthe oil levelcheck plug.

9.Securely reinstallthe gear oil fill plug on top of the transmission

10.Reinstall the wheel and remove the prop.
