BEFORE OPERATION
FUEL : MIXING GASOLINE AND OIL
The two cycle engines used in the brushcutter requires a mixture of GASOLINE and OIL for lubrication of
bearings and other moving parts. The proper fuel mixture ratio is 25 : 1, which is 40cc of oil mixed with one
liter of gasoline.
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 ALCOHOL 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.
OPERATING INSTRUCTIONS
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 "ON", and the throttle trigger positioned at Fast-idle
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 posi-
tion.
If the engine stops running before you turn the choke lever to the open posi-
tion:
Go ahead and open the choke, pull the starter grip with the throttle trigger
positioned at Fast-idle position.
HOT RESTART
To start the engine that is already warmed up (hot restart), or if the ambient temperature exceeds
68°F(20°C):
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 open position, and set the stop switch to the "ON" position.
3. Leave the throttle trigger in the idle position and pull the starter grip.
If the engine fails to start after you follow the above procedures, contact an authorized MARUYAMA dealer.
TO STOP THE ENGINE:
1. Release the throttle trigger.
2. Slide the stop switch to "STOP" position.
