building. Breathing exhaust fumes can cause death.
6. Keep the grip of handles clean of oil, fuel and dirt.
Multi-cutter safety
1. Make sure the Multi-cutter is assembled correctly and that the tool attachment is correctly installed
and securely fastened as instructed in the assembly section beginning on page 8.
2. Inspect the Multi-cutter before each use. Replace damaged parts. Check for fuel leaks.
Make sure all fasteners are in place and tightened securely. Follow the Maintenance instructions
beginning on page 25.
3. Shut off the engine and be certain the attached tool has completely stopped moving before
inverting the Multi-cutter, performing maintenance on or working on the machine.
4. Make sure the attached tool does not move at engine idle speed. Refer to Idle Speed Adjustment,
page 17.
5. Inspect the tool attachment and replace any parts that are cracked, chipped or damaged before
using the Multi-cutter.
6. Never use a tool attachment or replacement parts that are not approved by MARUYAMA.
7. Maintain the Multi-cutter according to the recommended maintenance intervals and procedures in
the Maintenance section beginning on page 25.
8. If running problems or excessive vibration occur, stop immediately and inspect the unit for the
cause. If the cause cannot be determined or is beyond your ability to correct, return the Multi-cutter
to your servicing MARUYAMA dealer for repair.

Fuel safety
1. Gasoline is highly flammable and must be handled and stored carefully. Use a container approved
for fuel for storing gasoline and/or fuel/oil mixture.
2. Mix and pour fuel outdoors and where there are no sparks or flames.
3. Do not smoke near fuel or Multi-cutter, or while using the Multi-cutter.
4. Do not overfill the fuel tank. Stop filling 10mm from the top of the tank.
5. Wipe up any spilled fuel before starting the engine.
6. Move the Multi-cutter at least 3m away from the fueling location before starting the engine.
7. Do not remove the Multi-cutter fuel tank cap immediately after stopping the engine.
8. Allow the engine to cool before refueling.
9. Drain the tank and run the engine dry before storing the unit.
10. Store fuel and Multi-cutter away from open flame, sparks and excessive heat. Make sure fuel
vapors cannot reach sparks or open flames from water heaters, furnaces, electric motors, etc.

shaft protruding from the driveshaft tube.
The squared end of the driveshaft positions
toward the connector of the power unit.
The splined end of the driveshaft connects
to the gearcase assembly.
Insert the driveshaft tube assembly into the
gearcase assembly while rotating the drive-
shaft to engage the splines. Align the locating holes and install the locating screw through
the side of the gearcase. Then tighten the clamping screws. If properly installed, ro-tating

Before Operation
Chain Oil (Pruner Attachment)

The chain and guide bar are lubricated by a centrifugal pump.
The oil discharge rate is controlled by the oil discharge Oil Discharge
Adjustment Screw
Oil Tank Filler Cap
adjustment screw on the top of the pruner head. Remove the
oil tank filler cap fill the tank, then replace the cap.
IMPORTANT: Only use oil designed for lubricating chain saw chains and guide bars. Do not use
waste oil. Never run the chain dry. In temperatures below freezing, check the chain oil viscosity
(pour point). If the oil is not rated for use below freezing, it may not provide adequate lubrication,
resulting in damage to the oil pump, chain and guide bar.
IMPORTANT: When filling the oil tank for the first time, or when the tank is completely empty, wait
approximately 60-90 seconds before starting the Pruner. This will give the oil time to flow from the
tank to the pump. Otherwise, an air lock can occur which will prevent oil from moving through the
pump. This will result in damage to the chain and guide bar.
Engine Oil and Fuel
1. Mix and pour fuel outdoors and where there are no sparks or flames.
2. Always shut off the engine before refueling. Never remove the Multi-Cutter fuel tank cap while the
engine is running or immediately after stopping the engine.
WARNING
POTENTIAL HAZARD
・Gasoline contains gasses that can build up pressure inside a fuel tank.
WHAT CAN HAPPEN
・fuel can be sprayed on you when removing fuel tank cap.
HOW TO AVOID THE HAZARD
・Remove fuel tank cap slowly to avoid injury from fuel spray.

―15 ―
3. Always open the fuel tank cap slowly to release any possible
pressure inside the tank.
4. Do not overfill the fuel tank. Stop filling 10mm from the top of the
3m
Minimum
tank.
5. Tighten the fuel tank cap carefully but firmly after refilling.
6. Wipe up any spilled fuel before starting the engine.
7. Move the Multi-Cutter at least 3m away from the fueling location
and fuel storage container before starting the engine.
DANGER
approved container and keep it out of the reach of children.
・Do not mix fuel for more than two month use.
・Do not fill the fuel tank completely. Add gasoline to the fuel tank until the level is 10mm
below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.
・Never smoke when handling gasoline, and stay away from an open flame with gasoline in an
Wipe up any gasoline that spills.
POTENTIAL HAZARD
・In certain conditions gasoline is extremely flammable and highly explosive.
WHAT CAN HAPPEN
・A fire or explosion from gasoline can burn you, others and cause property damage.
HOW TO AVOID THE HAZARD
・Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is cold.
Recommended Oil Type
Only use a two-cycle engine oil formulated for use in high-performance, air-cooled two-cycle engines.
IMPORTANT: Do not use two-cycle oil intended for water cooled outboard motors. This type of
two-cycle engine oil does not have the additives for air-cooled two-cycle engines and can cause
engine damage.
Do not use automotive motor oil. This type of oil does not have the proper additives for
air-cooled two-cycle engines and can cause engine damage.
Recommended Fuel Type
Use clean, unleaded gasoline with an octane rating of 85 or higher. Use of unleaded gasoline results in fewer
combustion chamber deposits and longer spark plug life. Use of premium grade fuel is not necessary or
recommended.
IMPORTANT: Never use gasohol or alcohol blended fuels in this engine.

Mixing Gasoline and Oil
IMPORTANT: The engine used on this Multi-cutter is of a two-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.
Fuel Mixture
The fuel: oil ratio is 25 parts gasoline to 1 part oil or 25:1.
Fuel Mixture Chart 25:1 Gasoline two-cycle oil
1litre 40ml
2litre 80ml
5litre 200 ml
Mixing Instructions
IMPORTANT: Never mix gasoline and oil directly in the Multi-cutter 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 Multi-cutter.
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 tank on the Multi-cutter.
6. When refilling the Multi-cutter fuel tank, clean around the fuel tank cap to stop dirt and debris from
