Section4: Operation

WARNING

Do not push down on the handlebars to try to make the tiller till more deeply. This prevents the wheels from holding the tiller back and can allow the tines to rapidly propel the tiller backward toward the operator, which could result in loss of control, property damage, or personal injury.

Let the tiller moveat its own paceand do not push down on the handlebarsto try to dig deeper- this takes weight off the wheels, cuts traction, andcausesthe tines to try and propel the tiller.

5.For reverse motion of the wheels and tines:

(a)Look behindand exercise caution when operating in reverse. Do not till while in reverse.

WARNING

Before tilling, contact your telephone or utilities company and inquire if underground equipment or lines are used in your area. Their representa- tive will be glad to answer your questions and tell you if any of their equipment or lines are buried underground on your property.
