DEPTHREGULATORLEVER
Thislever (F,Figure3-5) controls thetilling
depth of the tines. Pull the lever back and
slide it up or downto engagethe notched
height settings.
The"travel position" (highestnotch) raises
the tines approximately1-1/2" off the
ground, allowing the tiller to bemoved
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 allows a till-
ing depthof approximately6", depending
on soil conditions. For best results,always
begintilling at avery shallow depth setting
and gradually increasethe tilling depth.
WARNING: Donot attempt
to till too deeplytoo quickly.
Graduallywork downto deeper
tilling depths.
Placethe DepthRegulator
Lever in the "travel" position
before starting the engine. This
position prevents thetines from
