HANDLEBAR HEIGHT ADJUSTMENT

Thehandlebar height is adjustableto three different settings (Figure 3-6). In general, adjust the handlebars so they areat waist level when the tines are 3"-4"in the soil.

Toadjust the handlebars:

1.Stop engine, disconnect spark plug wire from spark plug and allow engine to cool.

2.Remove hardware,reposition handle- bars, and reinstall hardware securely.

3.Releasethe clutch bail to disengage (stop) the wheelsandtines (the enginewill continue to run).

REVERSECLUTCHCONTROL

(Models 634F/634B only)

The ReverseClutch Control (F,Figure 3-4) controls the engagementof reverse drive

to the wheelsand tines. The reversing feature is usedfor maneuveringthe tiller only-- never engage the tines in the

groundwhile operatingin reverse,

This lever (G, Figure3-5) controls the till- ing depth of the tines. Pull the lever back and slide it up or down to engagethe notched height settings.

The"travel position" (highest notch) raises

the tines approximately1-1/2" off the ground, allowing the tiller to be moved

without the tines contacting the ground. This setting should also be used when starting the engine.

Moving the lever upward will increasethe

tilling depth. Thelowest notch allowsa till- ing depth of approximately 6", depending

on soil conditions. For bestresults,always Figure3-6:Handlebarheightadjustment.
