,_ WARNING: Beforeinspecting, cleaning or servicing the machine,shut off engine, wait for all spark plug. Failureto follow these instructions can result in serious personal injury or property

damage.

4.Thegear oil level is correct if the gear oil is approximately halfway upthe side of the main drive shaft.

5.Ifthe gearoil level is low, addgear oil as described next. If the gearoil level is okay, securely replacethe oil fill plug.

IMPORTANT:Donot operatethe tiller if the gear oil level is low. Doing so will result in severedamageto the transmission com- ponents.

Figure 5-2: Remove oil fill p/ug (,4) to check gear oil level and to addgear oil. Remove four coverscrews (B) to draingear oil.

6.If adding only a few ounces of gear oil, use API rated GL-4or GL-5gearoil having a viscosity of SAE140, SAE85W-140 or SAE80W-90. If refilling an empty trans- mission, useonly GL-4gear oil having a viscosity of SAE85W-140 or SAE140.

IMPORTANT:Do not use automatic trans- mission fluid or motor oil inthe transmis- sion.

7.While checking frequently to avoid over- filling, slowly add gear oil into the oil fill hole until it reachesthe halfway point on the drive shaft.

8.Securely replacethe oil fill plug.

B. To Drain theTransmissionGear Oil:

Thetransmission gear oil does not needto bechanged unless it has beencontaminat- ed with dirt, sand or metal particles.

1.Drain gasoline from the fuel tank or run the engine until the fuel tank is empty. See "DANGER"statement below.

WARNING: Gasolineis

highly flammable andits vapors areexplosive. Followthese safety practicesto prevent personal injury or property damagefrom fire or explosion.

Allow the engine and muffler to cool for at least two minutes before drain-

ing the Uller'sgasolinetank.

Do not allow open flames, sparks, matchesor smoking in the area.

Wipe away spills and pushtiller away from spilled fuel.

Use only an approved fuel container and store it safely out of the reach of children.

Do not store gasoline in an area where its vaporscould reach an openflame or spark, orwhere ignitionsourcesare present (such as hot water and space heaters, furnaces, clothes dryers, stoves, electric motors, etc.)

2.Drain the oil from the engine.

3.Removefour screws (B, Figure5-2) and removetransmissioncoverandgasket.

4.Removethe left-side wheel.

5.Tilt the left-side wheel shaft into a drain panand allow the gearoil to drainthrough the top of the transmission.

6.Reinstall the wheel.

7.Install a new gasket (do not reuse old gasket) and reinstall the transmission cov- er.

8.Refill the transmission using GL-4gear oil (SAE85W-140 or SAE140).

9.Refill the enginewith motor oil and re- plenish the fuel tank with gasoline.

BOLOTINES

The bolo tines will wear with useand should be inspected at the beginning of eachtilling seasonand after every30 oper- ating hours. The tines can be replacedei- ther individually or as a complete set. See the Parts List pagesfor tine identification and part numbers.

A. Tine Inspection:

With use,the tines will becomeshorter, narrower and pointed. Badlyworn tines will result in a loss of tilling depth, and re- duced effectiveness when chopping up andturning under organic matter.

B. Removin_nstalling a Single Tine:

1.With the engine shut off andthe spark plug wire disconnected, remove the two

screws (A, Figure 5-3), lock washers (E) and nuts (B) that attach a single tine to a tine holder. If needed, use penetrating oil on the nuts.

2.When installing a single tine, besure to position it so that its cutting edge (sharp) will enter the soft first as the tiller moves forward.

C. Removin_nstalling a Tine Assembly:

1.Atine assemblyconsists of eight tines mounted on atine holder.

2.If removing both tine assemblies, mark them "left" and "right" before removal. Re- movethe screw (C,Figure5-3), lock wash-

er (E)and Iocknut (D) that secure the tine assemblyto the tine shaft. If necessary, usea rubber mallet to tap the tine assem- bly outward off the shaft.

3.Before reinstallingthe tine assembly,in- spectthe tine shaft for rust, roughspots or burrs. Lightly file or sand, as needed. Ap- ply a thin coat of greaseto the shaft.

4.Install each tine assemblyso that the

cutting (sharp) edge of the tines will enter thesoft first when the tiller moves forward.
