AUTION: Federal regulations require

an engine control to be installed on this
lawn mower in order to minimize the
risk of blade contact injury. Do not under
any circumstances attempt to defeat the

function of the operator control. The blade
turns when the engine Is running.

• Your lawn mower is equipped with an

operator presence control bar which

requires the operator to be positioned
behind the lawn mower handle to start
and operate the lawn mower.

DRIVE CONTROL
• Self-propelling is controlled by hold­

ing the operator presence control bar

down to the handle and pulling the drive

control lever rearward to the handle.

The farther toward the handle the lever

is pulled, the faster the unit will travel.

• Forward motion will stop when either

the operator presence control bar or
drive control lever are released. To stop
forward motion without stopping engine,

release only the drive control lever. Hold

operator presence control bar down

against handle to continue mowing

without self-propelling.

NOTE: If after releasing the drive control

the mower will not roil backwards, push
the mower forward slightly to disengage
drive wheels.
