HOW TO USE YOUR LAWN MOWER
ENGINE SPEED
The engine speed was set at the factory for optimum per-
formance. 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 un der
any cir cum stanc es 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 (See Fig. 5)
• 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 pres-
ence 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 against handle to con tin ue 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.
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 over spectacles.
