Mixing Gasoline And Oil
IMPORTANT: The engine used on this Pruner is of a
2-cycle design. The internal moving parts of the
engine, i.e., crankshaft bearings, piston pin bearings
and piston to cylinder wall contact surfaces, require
oil mixed with the gasoline for lubrication.
Failure to add oil to the gasoline or failure to mix oil
with the gasoline at the appropriate ratio will cause
major engine damage which will void your warranty.
For your fuel premix, use Maruyama Premium 2-
cycle Oil Mix, or equivalent ISO-L-EGD & JASO
FD oil with a minimum 89 octane high Quality
gasoline. Maruyama 2-cycle oil is specially formulat
-ed to meet the requirements of high-performance,
low-emission air-cooled 2-cycle engines. Use of other
oils may lead to service issues which may Not be
covered by your warranty.
Fuel Mixture
The fuel: oil ratio is 50 parts gasoline to 1 part oil or 50:1.
Note: Never use a mixing ratio less than 50:1
regardless of the oil package mixing
instructions. Ratios less than 50:1,
(for example, 60:1, 80:1, 100:1), reduce
the amount of lubrication to the internal
moving parts of the engine and can cause
damage.

Mixing Instructions
IMPORTANT: Never mix gasoline and oil
directly in the Pruner fuel tank.
1. Always mix fuel and oil in a clean container
approved for gasoline.
2. Mark the container to identify it as fuel mix for
the Pruner.
3. Use regular unleaded gasoline and fill the container
with half the required amount of gasoline.
4. Pour the correct amount of oil into the container
then add the remaining amount of gasoline.
5. Close the container tightly and shake it momentarily
to evenly mix the oil and the gasoline before
filling the fuel tank on the Pruner.
6. When refilling the Pruner fuel tank, clean around the
fuel tank cap to prevent dirt and debris
from entering the tank during cap removal.
7. Always shake the premix fuel container momen-
tarily before filling the fuel tank.
8. Always use a spout or funnel when fueling to
reduce fuel spillage.
9. Fill the tank only to within 1/4-1/2 inch (6 mm-13
mm) from the top of the tank. Avoid filling to the
top of the tank filler neck.
