CUTTING BLADE

A variety of metal cutting blades are
available to satisfy different cutting con-
ditions. It is especially important to use
only the correct blade(s) approved for
each model brushcutter. Also, it is
especially important to install the blade
for LEFT- HAND rotation (as viewed
from the operator's position), and to
correctly position all blade holding parts
(see sketch).

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 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.
