WARNING: Beforeinspecting, cleaning or servicing the machine,shut off engine, wait for all moving partsto come to a complete stop, disconnect spark plug wire and move wire awayfrom spark plug. Failureto follow these instructions can result in serious personalinjury or property damage.

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

5.If the gear oil level is low. add gearoil as described next. If the gear gellevel is okay, securely replacethe oil fill plug.

IMPORTANT:Do not operatethe tiller if the gear oil level is low. Doing so will result i_ severedamageto the transmission com- ponents.

Figure 5-2: Remove oil fittplug (.4) to check gear oil level andto add gear oil. Remove fourcoverscrews (B) to drain gear oil.

6.If adding only a few ouncesof gear oil. useAPI rated GL-4or GL-5gearoil having a wscosEtyof SAE140. SAE85W-140 or SAE80W-90. If refilling an empty trans- mission, use only GL-4gear oil having a viscosity of SAE85W-140 or SAE140. IMPORTANT:Do not use automatic trans- mission fluid or motor oil in the transmis- sion.

7.While checking frequently to avoid

overfilling, slowly add gear oil into the oil fill holeuntil it reachesthe halfway point on the drive shaft.

8.Securely replacethe oil fill plug.

B. To Drain the TransmissionGear Oil:

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

1. Drain gasolinefrom the fuel tank or run

the engine until the fuel tank is empty. See 'DANGER"statement below.

WARNING: Gasolineis highly flammable andits vapors are explosive. Followthese safety practicesto prevent personal injury or proper_y damage from fire or explosion.

Allowthe engineand mufflerto coolfor at least two minutes before draining the tiger'sgasolinetank.

Do not allow open flames, sparks, matchesor smokingin the area.

Wipe away spills and pushtiller away from spilled fuel.

Use only an approved fuel container and store it safely outof the reach of chil- dren.

Do not store gasolinein an area where its vapors could reach an open flame or spark, or where ignition sources are 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 reinstallthe transmission cov- er.

8.Refillthe transmission using GL-4 gear ozltSAE 85W-140 or SAE140).

9.Refillthe engine with motor oil and re- plenish the fuel tank with gasoline.

BOLO TINES

The bole tines will wear with use and should be inspected at the beginning of eachtilling seasonand after every30 oper- ating hours. The tines can be replacedel- ther individually or as acomplete set. See the Parts Lisl 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 effectivenesswhen chopping up andturning under organic matter.

B. Removin_nstalling a Single Tine:

1.With the engineshut off andthe spark plug wire disconnected, removethe two screws IA,Figure5-3), Iockwahers (Eband nuts (B) that attach a single tine to a tine holder. If needed,use penetratingoil on the nuts.

2.When installing a single tine. besureto position it so that its cutting edge (sharp) will enter the soil first as the rifler moves forward.

C. Removin_nstalling a Tine Assembly:

1.A tine assemblyconsists of eight tines mounted on atine ilolder.

2.If removing both tine assemblies mark them "left" and "right" before removal.

Removethe screw (C, Figure 5-3), lock washer (E_and Iocknut [D that securethe

tine assembly to the tine shaft. If neces- sary, use a rubber malletto tap the tine as- sembly outward off the shaft.

3.Before reinstalling the tine assembly, in- spect the 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 assembly so that the cutting (sharp) edge of the tines will enter the soil first whenthe tiller moves forward.
