ASSEMBLY INSTRUCTIONS

ENGINE AND DRIVESHAFT ASSEMBLY

The shaft and clutch drum housing assembly are already connected. Attach the shaft to the engine with the four M5×20 screws (packed with the engine).

LOOP HANDLE

The loop handle attaches to the shaft with four screws, as shown.

THROTTLE CABLE AND WIRING

Install the plastic tube (packed with the shaft assembly) around the throttle cable and stop-switch wires, as shown.

Remove the air filter cover to connect the stop-switch wires, as shown. (Connections are near the carburetor on the engine.)

The throttle cable end must be inserted into and through the brass-colored fitting held by the bracket on top of the carburetor. The wire-end lug fits into the slotted holder (as shown) on top of the carburetor. A HOLE IS PROVIDED FOR THE LUG AT ONE END OF THE WIRE SLOT.

ADJUSTING THE CUTTING BLADES

Before operating the power Hedge Trimmer it is necessary to check the adjustment of the cutting blades. Blades that are too loose may vibrate, and will not provide a clean, smooth cut.

CAUTION-BLADES THAT ARE TOO TIGHT CAN CAUSE OVERLOADING WHICH MAY DAMAGE THE EQUIPMENT.

To adjust the cutting blades, refer to the illustrations and locate the tension screws.

Loosen the tension screw locknuts. Gently turn the tension screws in until snug, then turn the tension screws back out 1/4 turn. While holding the screws in place, tighten the locknuts. Liberally coat the cutting blades with light oil. Start the engine and operate the Hedge Trimmer at full speed for at least one minute. Stop the engine, and when the blades are motionless, touch the blades with your hand.

CAUTION-DO NOT TOUCH THE SHARPENED EDGES OF THE CUTTING BLADES. THE CUTTING BLADES ARE EXTREMELY SHARP AND DANGEROUS AT ALL TIMES!!

The blades may be warm, but if they are too hot to touch, loosen the tension screws 1/8 turn.

BEFORE OPERATION

FUEL: MIXING GASOLINE AND OIL

CAUTION-READ SAFETY INSTRUCTIONS CONCERNING GASOLINE ON PAGE(2).

The two-cycle engine used on the MARUYAMA Power Hedge Trimmer requires a mixture of GASOLINE and OIL for lubrication of bearings and other moving parts. The correct fuel mixture ratio depends upon the type of two-cycle motor oil that is used. If MARUYAMA two-cycle oil is used, the proper fuel mixture ratio is 50:1, which is 2.5oz. of oil mixed with one gallon of gasoline. If other oil for two-cycle air cooled engines is used, the proper fuel mixture ratio is 25:1, which is 5.0 oz. of oil mixed with one gallon of gasoline.

NOTE: Gasoline and oil must be premixed in a clean gasoline container. Never mix gasoline and oil indoors or in the Power Hedge Trimmer fuel tank. Always use fresh gasoline.

Add a small quantity of unleaded regular gasoline to a gasoline container. Pour the proper amount of two-cycle oil into the gasoline container. Do not use multi-viscosity oils. Install the cap on the gasoline container before shaking. Shake the gasoline container vigorously so the oil mixes with the gasoline. Add the additional gasoline needed to complete the required amount (see the fuel mixture chart below).

IMPORTANT: Do not fill the fuel tank with gasoline that does not have oil mixed in it. Do not use gasoline additives because the engine could be damaged.

WARNING!!-NEVER USE GASOHOL OR ALCOHOL BLENDED FUELS IN MARUYAMA ENGINES.

Before filling the Power Hedge Trimmer 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 1/4-1/2 inch from the top of the tank. Avoid filling the fuel tank filler neck. Install the cap securely onto the fuel tank.

OPERATING INSTRUCTIONS

STARTING PROCEDURE

The carburetors on MARUYAMA engines do not contain a choke system and are designed to start at IDLE speed. A greater throttle setting will cause difficult starting. To properly start a "cold" engine, perform the following procedure.

Step #1) Pump the primer-bulb at the bottom of the carburetor until fuel can be seen flowing through the fuel-return line to the fuel tank. (Flowing fuel should be clear, not foamy or full of bubbles.)

Step #2) Fully depress the black injection button, then release.

Step #3) With the ignition switch "ON", and the throttle trigger positioned at IDLE, pull the starter cord. The engine should start at IDLE within 5 to 6 pulls.

For starting an engine that is already warmed-up(hot restart), or if the ambient temperature exceeds 70^ F( 20^ C), the injection button should not be used. Follow steps #1) and #3) only.

If the engine fails to start at the IDLE position, set the throttle trigger at the FAST-IDLE position (see sketch). Then repeat the starting procedure (prime, injection, and pull).

(If a MARUYAMA engine fails to start after following the above procedures, contact an authorized MARUYAMA dealer.)

ENGINE OPERATION

After starting, allow the engine to a run a few minutes to warm it up before using.

NOTE: DO NOT have the engine under any load during this warm up period.

By squeezing the throttle trigger, increase the engine RPM to the speed required for operation before placing the Power Hedge Trimmer under load. ALWAYS reduce the engine speed to idle when it is not edging. Do not operate the engine at high RPM's with no load.

STOPPING THE ENGINE

Always run the engine at idle speed for a few minutes to allow cooling before stopping. To stop the engine, move the stop-switch to the STOP position.

If the stop-switch fails to stop the engine, pump the primer-bulb at the bottom of the carburetor a few times, then depress the black injection button.

(Repair the stop-switch.)

CARBURETOR ADJUSTMENT

The carburetor has been carefully adjusted at the factory and should not require any further adjustment. Only the idling speed can be adjusted by turning the idle speed adjustment screw (see sketch). The correct idle speed is 2800-3200RPM. Turning the adjustment screw clockwise will increase the idle speed.

If further adjustment is necessary, please contact a local authorized MARUYAMA dealer.

CAUTION-Read the SAFETY INSTRUCTIONS on page(2) concerning the proper use of the Power Hedge Trimmer.

The MARUYAMA Power Hedge Trimmer is designed for cutting and trimming foliage and small branches up to 1/4 inches in diameter. Although the MARUYAMA Power Hedge Trimmer is capable of cutting larger diameter branches, wear and tear of the machine would be proportionally increased.

By adjusting the handle, the MARUYAMA Power Hedge Trimmer can be operated while positioned at either the right side or the left side of the operator. To adjust the loop handle, see the ASSEMBLY INSTRUCTIONS on page (3).

If it is necessary to reposition the throttle grip assembly, loosen the clamping screws at both ends of the assembly before moving the grip. Then use caution to prevent any damage to the throttle cable and stop-switch Wires.

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

When starting the engine, use a safe procedure. Hold the Power Hedge Trimmer flat against the ground with the left hand while pulling the starter grip with the right hand.

Always grip the Power Hedge Trimmer with both hands while it is in operation. Be sure the cutting blades are moving (at least half-throttle) before actual cutting begins. The Power Hedge Trimmer works best at full throttle.

REGULAR MAINTENANCE

AIR FILTER

The air filter should be cleaned each time the power Hedge Trimmer is used. (or more often with extreme conditions.) The filter cover can be removed by unscrewing the single knob (see sketch).

Remove the screen from the foam ring, wash the foam in kerosene or warm detergent, then squeezé dry. Apply oil (#30 wt.) to foam, removing all excess oil. Assemble and re-install air filter on carburetor.

CAUTION-The air filter screen is designed to fit the filter cover ONE WAY ONLY! It must not be reversed! Refer to the sketch and match the cuts in the screen to the plastic posts inside the filter cover. (The fit should be snug.)

SPARK PLUG

The spark plug should be removed from the engine and checked after each 25 hours of operation. The tips can be cleaned with a stiff brush. Adjust the gap to 0.024–0.028 inches (see sketch). Replace the spark plug if it is oil-fouled or damaged. The average spark plug life is approximately 100 hours.

CAUTION-Do not over-tighten the spark plug. The correct torque is 10-12 Ft.Lbs.

COOLING FINS

Free passage of air through the cylinder cooling fins is required to prevent poor engine performance and shortened engine life. Regularly check and clean all debris from the cooling fins by removing the engine cover (see sketch).

FUEL FILTER

The fuel filter is attached to the fuel pick-up tube inside the fuel tank. After each 25 hours of use, it should be checked for dirt or damage, and replaced if necessary.

A wire with a hooked end aids in removing the filter from the tank. Avoid damaging the fuel line.

SPARK ARRESTOR

The spark arrestor should be inspected and cleaned after each 20 hours of use. The spark arrestor is installed inside the exhaust outlet of the muffler, and is secured by one screw through the side of the exhaust outlet (see sketch). Remove the screw, and pull the spark arrestor from inside the exhaust outlet tube. (If using pliers, care must be used to avoid crushing the spark arrestor flange.) Solvent and stiff brushing will usually be required for cleaning. Re-install the spark arrestor and the fastening screw.

EXHAUST MUFFLER

The muffler should be inspected and cleaned after each 100 hours of use. The engine cover must be removed for access to the muffler. Four screws (see sketch) attach the muffler cover to the muffler body. When the cover is removed, the spark arrestor is revealed in the exhaust outlet tube of the muffler cover. Remove the one screw securing the spark arrestor to the muffler cover and separate them. Clean the cover and the spark arrestor. (see instructions-Spark Arrestor.) It is not necessary to remove the muffler body from the cylinder for cleaning, BUT special care should be taken to prevent any debris from entering the exhaust ports. Use liquid gasket P/N 261910 to form the gasket between the muffler body and cover. Use Loctite P/N 261911 on the four screws attaching the cover to the muffler body. Secure the spark arrestor into place with the fastening screw.

The gearcase and angle drive should be checked for lubrication after each 10 to 20 hours of use. Grease fittings are installed into both components.

Use a good quality #2 lithium-base bearing lubricant.

Lubrication of the cutting blades should be maintained at all times. Use a light oil(#10 wt.)

GENERAL CLEANING AND TIGHTENING

The MARUYAMA Power Hedge Trimmer will provide maximum performance for many, many hours if it is maintained properly. Good maintenance includes regular checking of all fasteners for correct tightness, and cleaning the entire machine. Pitch and gum deposits should be removed from the cutting blades daily. Adjustment of the cutting blade tension should be checked regularly. Refer to page four for instructions to adjust cutting blades.

STORAGE

ALL MODELS: For long-term storage of the Power Hedge Trimmer, perform all regular maintenance procedures and needed repairs. Empty the fuel tank. Disconnect the fuel-return tube from the carburetor, then continue to pump the primer bulb until fuel stops discharging from the fuel-return fitting. Start the engine and allow it to run until it stops. Pull the starter cord a few times to remove any excess fuel from the engine. Remove the spark plug and insert a small amount of oil. Pull the starter cord once and bring the piston to a position closest to the spark plug hole. Re-install the spark plug. Apply a thin coating of oil to the entire machine and store in a dry place.
