HOW TO USE YOUR LAWN MOWER
ENGINE SPEED
The engine speed was set at the factory
for optimum performance. Speed is not
adjustable.
ENGINE ZONE CONTROL
CAUTION: Federal regulations re quire
an engine control to be installed on this
lawn mower in order to minimize the
risk of blade contact injury. Do not un der
any circumstances attempt to de feat the
func tion of the operator con trol. The blade
turns when the engine is running.

operator pres ence 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 stop ping engine,
re lease the drive control lever only. Hold
op er a tor presence control bar down

NOTE: If after releasing the drive control
the mower will not roll backwards, push
the mower forward slightly to disengage
drive wheels.
• To keep drive control engaged when
turning corners, push down on the
handle to lift the front wheels off the
ground while turning lawn mower.

become “loose”, resulting in decreased
speed. There is a turnbuckle on the
un der side of the drive control housing to
increase tension on the drive cable. Pro-
