“VARI-SPEED” DRIVE CONTROL
• Self-propelling is controlled by hold-
ing the operator presence control bar
down to the handle and pulling the drive
control
bar up to the handle. The closer
to the handle the bar is pulled, the faster
the unit will travel.
• Forward motion will stop when either the
operator presence control bar or drive
control bar are released. To stop forward
motion without stop ping engine, re lease
the drive control bar 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.
FRONT WHEEL DRIVE MODELS ONLY:
• 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.
VARI-SPEED “THUMBSCREW”
ADJUSTMENT
Over time, the drive control system may
become “loose”, resulting in decreased
speed. There is a thumbscrew on the
un der side of the drive control housing to
increase tension on the drive cable. Pro-
ceed as follows:
• Turn unit off and disconnect spark plug
wire from spark plug.
• Rotate thumbscrew counter-clockwise to
tighten the drive cable.
• Operate mower to test drive speed.
If condition fails to improve after the
above steps (forward speed remains
the same), your drive belt is worn and
should be re placed.
NOTE: If mower begins to "creep" forward,
the drive cable is too tight. Rotate thumb-
screw clockwise to loosen drive cable.
