NOTE : Gasoline and oil must be premixed in a clean gasoline container. Never mix gasoline and oil indoors
or in the burushcutter fuel tank. Always use fresh gasoline.
WARNING !! - NEVER USE GASOHOL OR ALCOHOL BLENDED FUELS IN MARUYAMA ENGINES.
Before filling the brushcutter fuel tank, clean around the fuel tank cap so dirt and debris does not enter the fuel
tank. Always shake the fuel container before filling the fuel tank. Remove the fuel cap, then fill the fuel tank to
within about 10mm from the top of the tank. Avoid filling the fuel tank filler neck. Install the cap securely onto
the fuel tank.

Starting and Stopping
COLD STARTING PROCEDURE
The carburetor on this engine is equipped with a fuel primer and a
choke system. To start a "cold" engine properly, perform the following
procedure:
1. Pump the primer bulb until fuel can be seen flowing through the fuel
return line to the fuel tank. (Flowing fuel should be almost clear, not
foamy or full of bubbles.)
2. Turn the choke lever to the Close position.
3. With the stop switch "START" (ON), and the throttle trigger
positioned at Fast-idle start position, pull the starter grip.
After the engine is started, turn the choke lever to the Open position.
Then squeeze and release the throttle trigger to allow it to return to the
idle position.
If the engine stops running before you turn the choke lever to the open
position:
Go ahead and open the choke, pull the starter grip with the throttle
trigger positioned at Fast-idle start position.
