FUEL; MIXING GASOLINE AND OIL

IMPORTANT The engine used on this Hedge Trimmer is of a 2-cycle design. The internal moving

parts of the engine, i.e., crankshaft bearings, piston pin bearings and piston to wall contact sur-

faces, 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 and will void

your warranty. For your fuel premix, use Maruyama Premium 2-Cycle Oil Mix, or equivalent ISO-L-

EGD & JASO FC oil with a minimum 89 octane high Quality gasoline. Maruyama 2-cycle oil is spe-

cially formulated 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: When using genuine Maruyama 50:1 2-Cycle Oil, or a quality oil designed for

2-cycle air-cooled engines, oil ratio is 50 parts gasoline to 1 part oil or 50:1.

CAUTION! If Maruyama oil is not used, never use a mixing ratio less than 50:1 regardless of the

oil package mixing instructions. Ratios less the 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.

FUEL MIXTURE CHART:

Gasoline Maruyama 50:1 2-Cycle Oil Gasoline Maruyama 50:1 2-Cycle Oil

1 gallon 2.6 oz. 1 litre 20ml

2 1/2 gallons 6.4 oz. 2 litre 40ml

5 gallons 12.8 oz. 5 litre 100ml

MIXING INSTRUCTIONS: Always mix fuel and oil in a clean container approved for gasoline.

Mark the container to identify it as fuel mix for the Hedge Trimmer. Use regular unleaded gasoline

and fill the container with half the required amount of gasoline. Pour the correct amount of oil

into the container then add the remaining amount of gasoline. Close the container tightly and

shake it momentarily to evenly mix the oil and the gasoline before filling the fuel tank on the Hedge

Trimmer.

When refilling the Hedge Trimmer fuel tank, clean around the fuel tank cap to prevent dirt and

debris for entering the tank during cap removal. Always shake the premix fuel container

momentarily before filling the fuel tank.

Always use a spout or funnel when fueling to reduce fuel spillage. Only fill the tank to within 1/4-

1/2 inch (6mm-13mm) from the top of the tank. Avoid filling to the top of the tank filler neck.

When the throttle trigger is released the engine should return to an idle speed which is 2700-3300

rpm or just below clutch engagement speed. The cutting blades must not move and the engine

should not stall (stop running) at engine idle speed.

The engine idle speed is adjusted by rotating the idle

speed screw on the carburetor. Turning the idle speed

screw in (clockwise) increases engine speed while

turning the screw out decreases engine speed.

If idle speed adjustment is necessary and after adjustment the cutting blades move or the

engine stalls, stop using the Hedge Trimmer immediately!

OPERATING THE POWER HEDGE TRIMMER

CAUTION—Read the WARNING on page (10) concerning the proper use of the

Hedge Trimmer.

The MARUYAMA Hedge Trimmer is designed for cutting and trimming foliage and small branches

up to 1/4 inches (6mm) in diameter. Although the MARUYAMA Hedge Trimmer is capable of

cutting larger diameter branches, wear and tear of the machine would be proportionally increased.

CAUTION—Always wear gloves and protective clothing when operating the Hedge

Trimmer.

If the cutting blades become jammed, stop the engine immediately. Make certain all moving parts

have stopped and disconnect the spark plug before inspecting the equipment for damage. Never

use a Power Hedge Trimmer that has chipped, cracked, or broken cutting blades.

REGULAR MAINTENANCE

Maintenance, replacement or repair of emission control devices and systems may be performed by

any repair establishment or individual; however, warranty repairs must be performed by a dealer

or service center authorized by Maruyama Manufacturing Company, Inc. with Maruyama U.S.,

Inc. The use of parts that are not equivalent in performance and durability to authorized parts may

impair the effectiveness of the emission control system and may have a bearing on the outcome of a

warranty claim.

AIR FILTER

Maintenance Interval: The air filter should be cleaned

daily or more often when working in extremely dusty condi-

tions and replaced after every 100 hours of operation.

Maintenance: Push and open the air filter cover.

Remove the foam filter. Clean the filter with warm, soapy

water. Let the filter completely dry. Lightly apply SAE 30

motor oil to the foam filter and squeeze out all excess oil.

Reassemble the filter and filter cover.

FUEL FILTER

Maintenance Interval: The fuel filter should be replaced

after every 100 hours of operation.

Maintenance: The fuel filter is attached to the end of the

fuel pick-up hose inside the fuel tank. To replace the fuel

filter, first make sure the fuel tank is empty. Remove the

fuel cap. Using a wire hook, gently pull the fuel filter out

though the fuel filter opening. Grasp the fuel hose next to

the fuel filter fitting and remove the filter but do not

release the hose. While still holding on to the fuel hose, attach the new fuel filter. Drop the fuel

filter back into the fuel tank. Make sure that the fuel filter is not stuck in a corner of the tank and

that the fuel hose is not doubled over (kinked) before refueling.

SPARK PLUG

Maintenance Interval: The spark plug should be remove from the engine and checked after each

25 hours of operation and replaced after every 100 hours of operation.

Maintenance: With the engine at ambient (room) temperature,

twist the high tension lead boot on the spark plug back and forth

a couple of times to loosen boot then pull the boot off of the spark

plug. Remove the spark plug. The electrodes can be cleaned

with a stiff brush. Adjust the electrode air gap to 0.6

(0.024

0.028 in.). Replace the spark plug if it is oil-fouled,

damaged or if the electrodes are worn down. Do not

overtighten the spark plug when installing. The tightening

torque is 10.7

148 in. lbs.). Reinstall the cylinder and muffler covers.

CYLINDER COOLING FINS

Maintenance Interval: The cylinder cooling fins should be cleaned after every 25 hours of opera-

tion or once a week which ever comes first. Air must flow freely around and through the cylinder

cooling fins to prevent engine overheating. Leaves, grass, dirt and debris buildup on the fins will

increase the operating temperature of the engine which can reduce engine performance and

short en engine life.

Maintenance: With the engine at ambient (room) temperature, remove the two socket head

screws, and remove the cover (FIG.1). Remove the two socket head screws, and remove the tail

pipe. Loosen the cylinder cover screw (knob) and lift off the cylinder cover. Clean all dirt and

debris from the cooling fins and from around the cylinder base. Reinstall the cylinder cover, tail

pipe and the cover (FIG.2).
