ATTACHING THE SHIELD
WARNING:
The shield must be prop-
erly installed. The shield provides partial
protection from the risk of thrown objects to
the operator and others and is equipped with
a line limiter which cuts excess line. The line
limiter (on underside of shield) is sharp and
can cut you.

WARNING:
Be sure to read the fuel
information in the safety rules before you be-
gin. If you do not understand the safety rules,
do not attempt to fuel your unit. Contact an
authorized service dealer.
FUELING ENGINE
WARNING:
Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality 2-cycle air-cooled en-
gine oil. We recommend McCulloch brand oil
mixed at a ratio of 40:1 (2.5%). A 40:1 ratio is
obtained by mixing 5 liters of unleaded gasoline
with 0,125 liter of oil. DO NOT USE automotive
oil or boat oil. These oils will cause engine dam-
age. When mixing fuel, follow instructions
printed on oil container. Once oil is added to
gasoline, shake container momentarily to as-
sure that the fuel is thoroughly mixed. Always
read and follow the safety rules relating to fuel
before fueling your unit.
IMPORTANT
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 stor-
age. Acidic gas can damage the fuel system
of an engine while in storage. To avoid engine
problems, empty the fuel system before stor-
age for 30 days or longer. Drain the gas tank,
start the engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel next
3. Pivot shield until bolt passes through hole
in bracket.
4. Reinstall nut and tighten securely with
wrench (provided).
