Pull and hold lever, raise or lower the handle to de-
sired position, then release lever. The lever can be
locked back to allow a “floating” handle position if
desired.
The engine has a contained centrifugal clutch, so
increasing engine RPM above 2000 will engage the
drive. Releasing the throttle lever brings engine back
to idle speed and disengages drive.
Place the unit into transport position. Pull the clevis
pin out and slide the height plate until the desired
depth lines up with the 2”, 3” or 4” deep decal. Re-
place the pin, the 1/2” pin should line up with the
desired setting. Three depth positions are available,
2”, 3”, 4” deep.
