Frequently Asked Questions - HT250L Maruyama

What is the correct fuel mixture for the Maruyama HT250L hedge trimmer?

If using Maruyama 2-cycle oil, mix at 50:1 (2.5 oz oil per gallon of gasoline). If using other 2-cycle oil, mix at 25:1 (5.0 oz oil per gallon of gasoline). Never use gasohol or alcohol-blended fuels.

How do I start the hedge trimmer?

Pump the primer bulb until fuel flows through the return line. Set choke to closed (I) position. Ensure stop switch is ON, then pull starter cord. Once running, open choke (≡). For warm engine, skip choke.

How do I adjust the cutting blade tension?

Loosen the nuts, turn screws clockwise until snug, then back out 1/4 turn. Tighten nuts while holding screws. Lubricate blades. Run at full speed for 1 minute, then check blade temperature. If too hot, loosen screws another 1/8 turn.

What safety gear should I wear while operating?

Always wear safety glasses or eye protection, hearing protection, gloves, substantial footwear, long pants, and a long-sleeved shirt. Avoid loose clothing and jewelry.

How do I stop the engine in an emergency?

Move the stop switch to STOP position. If it fails, pump primer bulb a few times and close choke lever. Repair the stop switch as soon as possible.

How often should I lubricate the gearcase and angle drive?

Every 10 to 20 hours of use. Use #2 lithium-base bearing grease. Also regularly lubricate cutting blades with light oil (#10 wt).

What is the blade length and maximum cutting capacity?

The blade length is 40 inches (101.6 cm). It is designed for foliage and branches up to 1/4 inch (6.4 mm) in diameter.

How do I store the hedge trimmer for long periods?

Empty fuel tank. Disconnect fuel-return tube and pump primer bulb until dry. Run engine until it stops. Remove spark plug, add oil, pull cord, then reinstall plug. Apply oil coating to machine and store in a dry place.

What is covered under the warranty?

Defects in material and workmanship. Residential: 3 years, commercial: 2 years, rental: 1 year. Emission-related parts (carburetor, ignition, spark plug) are covered for 2 years.

Can I use the hedge trimmer for cutting branches larger than 1/4 inch?

While capable, it is not recommended as it increases wear. For best performance and longevity, stick to branches up to 1/4 inch diameter.

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 GASCHOL 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.

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 screws.

Loosen the nuts.

Gently turn the screws in until snug, then turn the screws back out 1/4 turn.

While holding the screws in place, tighten the nuts. 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 screws 1/8 turn.

OPERATING INSTRUCTIONS

Check if any of the bolts and nuts need to be tightened.

STARTING PROCEDURE

(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.

(2) Turn the choke lever to the close ( I ) position.

(3) With the switch "ON", pull the starter cord. After the engine is started, turn the choke lever to the open (≡) position.

For starting an engine that is already warmed-UP, or if the ambient temperature exceeds 20°C (68°F), perform (1), turn the choke lever to the open (≡) position, and perform (3).

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 turn the choke lever to the close ( I ) position. (Repair the stop-switch.)

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.

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

ENGINE

Refer to "ENGINE INSTRUCTION MANUAL".

LUBRICATION: GEARCASE AND ANGLE DRIVE

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 5 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.
