The operationof any
lawn mower can result
in foreign objects thrown
into the eyes, which can
result in severe eye dam-
age. Always wear safety glasses or eye
shieldswhile operating your lawn mower
or performing any adjustmentsor repairs.
We recommend a standard safety glasses

HOW TO USE YOUR LAWN MOWER
ENGINE SPEED
Engine speed was set at the factory for
optimum performance. It is not adjustable.
DRIVE CONTROL ADJUSTMENT
Over time, the drive control system may
become "loose", resulting in decreased
speed. There is a turnbuckle on the drive
control housing to increase tension on the
drive cable. Proceed as follows:
1. Turn unit off and disconnect spark plug
wire from spark plug.
2. Rotate turnbuckle on drive control to
increase drive speed.
3. Operate mower to test drive speed.
Readjust as required.
4. If condition fails to improve after the
above steps (forward speed remains
the same), your drive belt is worn and
should be replaced.
ENGINE ZONE CONTROL
_CAUTION: 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 the drive control lever only. 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 roll backwards, push
the mower forward slightly to disengage
drive wheels.
