2. Do not start the engine until any spilled fuel evaporates.

STARTING THE ENGINE

WARNING! Do not start or run engine in enclosed area, even if doors or windows are open. Engine exhaust
contains carbon monoxide, an odorless and colorless poison gas.
WARNING! Failure to follow the steps below will result in rapid retraction of the starter cord faster than the
user can let go. This will pull the user's hand and arm toward the engine, possibly resulting in serious injury.
WARNING! Direct-coupled equipment components such as, but not limited to, blades, impellers, pulleys,
sprockets, etc., must be securely attached before the engine is started to avoid injury or damage.
1. Pull the choke rod out when the engine is cold. This will close the choke and restrict the fuel.
a. As the engine warms, release the choke rod to open the choke.
2. Engage the brake lever to release the flywheel brake.
3. Pull the starter grip lightly until resistance is felt, then pull briskly.
NOTICE! Do not allow the starter grip to snap back against the engine. Return it gently to prevent
damage to the starter.
4. Hold the flywheel brake lever to keep engine running.
5. Release the brake lever to stop the engine.
Occasionally you may hear a light 'spark knock' or 'pinging' (metallic rapping noise) while operating under heavy
loads. This is no cause for concern.
Should the spark knock or pinging continue to occur when the engine speed is steady under a normal load,
consider replacing the fuel. If the sounds continue after changing the fuel, contact Princess Auto Ltd. for a solution
or see a qualified technician.
NOTICE! Running the engine with persistent spark knock or pinging can cause engine damage.

FUEL RECOMMENDATIONS

This engine is certified to operate on unleaded gasoline with a minimum of 87 octane/87 AKI (91 RON). Gasoline
with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether) is acceptable.
NOTICE! Do not use unapproved gasoline, such as E85. Do not mix oil in gasoline or modify the engine to run
on alternate fuels. This will damage the engine components. To protect the fuel system from gum formation,
mix a fuel stabilizer into the fuel.
IMPORTANT! If the engine is routinely operated at altitudes over 5,000 ft (1,524 meters), it will be necessary
to have a qualified technician modify the engine for increased performance. Fuel should be a minimum of 85
octane/85 AKI (89 RON) to prevent decreased performance.
HOW TO ADD FUEL
WARNING! Do not refuel the engine inside a building. Gasoline and its vapors are extremely flammable and
explosive. Keep gasoline away from appliance pilot lights, barbecues, electric appliances, power tools, etc.
Do not use stale or contaminated gasoline or oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.
1. Clean the fuel cap area of dirt and debris. Remove the fuel cap.
2. Refuel outdoors or in a well-ventilated area.
3. Stop the engine and place it on a level surface.
4. Let engine cool at least 2 minutes before removing the fuel cap.
5. Check the fuel level.
