HOWTO USEYOUR 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 minimizethe 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 isequipped 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 holding 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 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.
