IMPORTANT: Never mix gasoline and oil
directly in the Pruner fuel tank.
Mixing Gasoline And Oil
1. Always mix fuel and oil in a clean container
approved for gasoline.
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.
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.
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.
4. Pour the correct amount of oil into the container
then add the remaining amount of gasoline.
For your fuel premix, use Maruyama Premium 2-
5. Close the container tightly and shake it momentarily

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.
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.
Fuel Mixture
The fuel: oil ratio is 50 parts gasoline to 1 part oil or 50:1.
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.
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.

Starting And Stopping
3. Lock the throttle trigger in the fast-idle start
position, then pull the starter grip.
Before Starting The Engine
1. Fill the fuel tank as instructed in the Before Operation
section of this manual (page US-14).
2. Rest the Pruner on the ground.
3. Make sure the cutting attachment is clear of any
broken glass, nails, wire, rocks or other debris.
4. Keep all bystanders, children and animals away
from the working area.
Cold Starting Procedure
This Pruner 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 at the bottom of the carbu-
retor 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. Move the choke lever to the closed ( ) position
and move the stop switch to the “ON” position.

CAUTION
• Do not pull the Starter rope all the wayout.
WARNING
• Do not disassemble the Starter. Please ask for
an authorized MARYAMA service dealer.
4. After the engine starts, squeeze and release the
throttle trigger to return it to the idle position, then
move the choke lever to the open ( ) position.
If the engine stops running before you move the
choke lever to the open ( ) position:
A. Go ahead and open the choke.
B. Make sure the throttle trigger is set to the idle
position.
C. Pull the starter grip until the engine starts.
Hot Restart
To start an engine that is already warmed up (hot
restart), or if the ambient temperature exceeds 68°F
(20°C):
1. Pump the primer bulb at the bottom of the car-
buretor until fuel can be seen flowing through the
fuel return line to the fuel tank.
2. Move the choke lever to the open ( ) position
and move the stop switch to the “ON” position.
3. Leave the throttle trigger in the idle position and
pull the starter grip.
