The operation of any lawn
mower can result in foreign
objects thrown into the
eyes, which can result in
severe eye damage.
Always wear safety glasses or eye
shields while operating your lawn mower
or performing any adjustments or repairs.
We recommend standard safety glasses
or a wide vision safety mask worn over
spectacles.
HOWTO
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 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 holding
the operator presence control bar down
to the handle and pushing the drive
control lever forward until it clicks; then
releasing the lever.
• Forward motion will stop when the
operator presence control bar is
released. To stop forward motion
without stopping engine, release the
operator presence control bar slightly
until the drive control disengages. Hold
operator presence control bar down
against handle to continue mowing
without self-propelling.
• To keep drive control engaged when
turning corners, push down on handle
and lift front wheels off ground while
turning lawn mower.
