OPERATION
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 a wide vision safety
mask over the spectacles or standard safety glasses.

A
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

running.
* Your lawn mower is equipped with an operator pres­
ence control bar which requires the operator to be
positioned behind the lawn mower handle to start and
operate the lawn mower.

After the first two (2) hours of mowing, change the oil,
and every 25 hours thereafter. You may need to
change the oil more often under dusty, dirty conditions.
GAS (See Fig. 7)
• Fill fuel tank. Use fresh, clean, regular unleaded
gasoline with a minimum of 87 octane, Do not mix oil
with gasoline. Purchase fuel in quantities that can be
used within 30 days to assure fuel freshness.
WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and formation of
acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid engine
problems, the fuel system should be emptied before stor­
age of 30 days or longer. Drain the fuel tank, start the
engine and let it run until fuel lines and carburetor are
empty. Use fresh fuel next season. See Storage Instruc­
tions for additional information. Never use engine or
carburetor cleaner products in fuel tank or permanent
damage may occur.
