Frequently Asked Questions - MT42 Maruyama

What fuel mixture does the MT42 require?

The MT42 runs on a 50:1 gasoline to 2-cycle oil mixture. Use unleaded regular gasoline (89+ octane) with no more than 10% alcohol/ethanol. Use Maruyama BLUE Ultra-Shield oil for best results.

How do I start the engine?

1. Pump the primer bulb until fuel flows through the return line. 2. Set choke to CLOSE. 3. Turn stop switch ON, hold throttle at fast-idle, and pull the starter grip. After starting, move choke to HALF then ON.

How do I adjust the tilling depth?

Use the drag stake: pull the detent pin, rotate the stake so the pointed tip faces down, and insert the pin into the desired height hole. Lower stake = deeper cultivation.

How do I clean the air filter?

Loosen the knob and remove the cover. Take out the foam element, wash with warm soapy water, let dry completely. Apply a light coat of SAE 30 oil, squeeze out excess, and reassemble.

What is the recommended spark plug and gap?

Use NGK BPM8Y spark plug with a gap of 0.024-0.028 inches (0.6-0.7 mm). Torque to 95-148 in-lbs when installing.

Why won't the engine start?

Check: 1. Stop switch is ON. 2. Spark plug wire connected. 3. Fuel tank has fresh mixture. 4. Spark plug is clean and properly gapped. 5. Throttle is held open during pull.

How do I transport the mini-cultivator safely?

Screw the gas cap and vent screw tightly. Transport upright in an open vehicle. If using an enclosed vehicle, drain fuel into an approved container. Never siphon by mouth.

What maintenance is required every 8 hours?

Clean the engine and check all bolts and nuts for tightness. Also inspect the air filter and clean if needed.

Can I use the tines in reverse?

No. The tines are designed for forward rotation only. Never operate in reverse; the tines will not turn and forcing it may damage the machine.

What is the break-in period?

The clutch will transfer maximum power after about 2 hours of normal operation. During this period, clutch slippage may occur. Keep clutch free of oil and moisture.

ENGINE SAFETY PRECAUTIONS

Warning Carbon Monoxide Poisoning

Engines give off carbon monoxide, an odorless, colorless, poisonous gas. Carbon monoxide may be present even if you do not smell or see any engine exhaust. Breathing carbon monoxide can cause nausea, fainting or death, in addition to drowsiness, dizziness and confusion. If you experience any of these symptoms, seek fresh air and medical attention immediately.

If your product comes with a separate engine manual, be sure to read and follow all safety and warning precautions outlined there, in addition to any in this manual.

Preventing Carbon Monoxide Poisoning

• Always start and run engine outdoors. Do not start or run engine in an enclosed area, even if doors or windows are open.
- Never try to ventilate engine exhaust indoors. Carbon monoxide can reach dangerous levels very quickly.
- Never run engine outdoors where exhaust fumes may be pulled into a building.
- Never run engine outdoors in a poorly ventilated area where the exhaust fumes may be trapped and not easily taken away. (Examples include: in a large hole or areas where hills surround your working area.)
- Never run engine in an enclosed or partially enclosed area. (Examples include: buildings that are enclosed on one or more sides, under tents, car ports or basements.)
• Always run the engine with the exhaust and muffler pointed in the direction away from the operator.
- Never point the exhaust muffler towards anyone. People should always be many feet away from the operation of the engine and its attachments.
- Do not change the engine governor settings or over-speed the engine.

Gasoline Fires and Handling Fuel Safely

Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.

• When storing extra fuel be sure that it is in an appropriate container and away from any fire hazards.
• Prevent fire and explosion caused by static electric discharge. Use only nonmetal, portable fuel containers approved by the Underwriter's Laboratory (U.L.) or the American Society for Testing & Materials (ASTM).
  • Always fill fuel tank outside in a well ventilated area. Never fill your fuel tank with fuel indoors. (Examples Include: basement, garage, barn, shed, house, porch, etc.) Never fill tank near appliances with pilot lights, heaters, or other ignition sources. If the fuel has to be drained, this should

MAINTENANCE:

Air Filter Cleaning

Maintenance Interval

• The air filter should be cleaned daily, or more often when working in extremely dusty conditions.

• Replace after every 100 hours of operation.

• Loosen the knob and remove the air filter cover.

• Remove the foam element.
• Clean the foam element with warm, soapy water. Let the element dry completely.
• Apply a light coat of SAE 30 motor oil to the foam element and squeeze out all excess oil.
• Reassemble the foam element and filter cover.

IMPORTANT

NEVERTWIST AIR FILTERS WHEN CLEANING. ALWAYS PRESS.

Cylinder Cooling Fins

Maintenance Interval

• The cylinder cooling fins should be cleaned after every 25 hours of operation, or once a week, whichever 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 shorten engine life.

Cooling Fin Cleaning

1. With the engine at ambient (room) temperature, loosen the knob and remove the air filter cover.
2. Loosen the knob and lift off the cylinder cover.
3. Clean all dirt and debris from the cooling fins and from around the cylinder base.
4. DO NOT overlook cleaning of the cooling air intake area below the crankcase and above the fuel tank! This area must be free of debris and obstruction for the engine to cool properly.
5. Reinstall the cylinder cover.

Fuel Filter

Maintenance Interval

The fuel filter should be replaced after every 100 hours of operation.

Fuel filters needing more frequent replacement may indicate debris in fuel tank.

Fuel Filter Replacement

The fuel filter is attached to the end of the fuel pick-up hose inside the fuel tank.

To replace the fuel filter:

1. Make sure the fuel tank is empty.
2. Remove the fuel cap.
3. Using a wire hook, gently pull the fuel filter out through the fuel filler opening.
   Use caution not to "fishook" the fuel tube. Replace immediately if punctured!
4. Grasp the fuel hose next to the fuel filter fitting and remove the filter, but do not release the hose.
5. While still holding on to the fuel hose, attach the new fuel filter.
6. Drop the new fuel filter back into the fuel tank.
7. 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 removed from the engine and checked after each 25 hours of operation.
• Replace the spark plug after every 100 hours of operation.

Spark Plug Maintenance

1. Twist the high tension lead boot on the spark plug back and forth a couple of times to loosen the boot, then pull the boot off of the spark plug.
2. Remove the spark plug.
3. Clean the electrodes with a stiff brush.

1. Adjust the electrode air gap to .024-.028 in (0.6-0.7 mm).
2. Replace the spark plug if it is oil-fouled, damaged, or if the electrodes are worn down.
3. Do not overtighten the spark plug when installing. The tightening torque is 95-148 in. lbs. (10.7-16.6 N·m).
4. Always use only the specific heat range of spark plug. This is particularly critical with today's low-emission engines. For best results, use the exact replacement.

Spark Arrester

Maintenance Interval

• The spark arrester should be inspected and cleaned after every 25 hours of use.
• Replace the screen if it cannot be thoroughly cleaned, or if it is damaged.

Spark Arrester Maintenance

1. With the engine at ambient (room) temperature, loosen the knob and remove the air cleaner cover.
2. Loosen the knob and lift off the cylinder cover.
3. Remove a screw located on the side of the exhaust outlet holds the spark arrester in place.
4. Withdraw the spark arrester, using a suitable pair of pliers.

Note: Do not crush or distort the spark arrester flange during removal.

1. The screen can be cleaned using a non-flammable solvent and stiff wire brush.

Note: If any part cannot be thoroughly cleaned, it must be replaced.

1. To install insert the spark arrester into the exhaust outlet while aligning the holes in the arrester flange and outlet for the retaining screw. Then install the screw.

2. Reinstall the cylinder and air filter covers.

Exhaust Muffler

Maintenance Interval

The muffler should be inspected and cleaned after each 100 hours of use.

Muffler Maintenance

1. With the engine at ambient (room) temperature, loosen the knob and remove the air filter cover.
2. Loosen the knob and lift off the cylinder cover.
3. Withdraw the spark arrester using a suitable pair of pliers.

Note: Do not crush or distort the spark arrester flange during removal.

1. Remove the three socket head screws holding the muffler body from cylinder.
2. Clean exhaust port of cylinder, exhaust outlet of muffler and spark arrester with safety solvent and stiff brush.

IMPORTANT: Be careful not to allow any dirt or debris to fall into the exhaust ports, as this can cause engine damage.

1. To reassemble the muffler body to the cylinder, apply Removal Loctite to the three socket head screws, then reinstall and tighten the three screws.
2. Reinstall the spark arrester onto the muffler body, then reinstall and tighten the screw.
3. Reinstall the cylinder and air filter covers.

TINE REMOVAL AND INSTALLATION

To Remove Tines

1. Remove the cotter pins from each end of the tine shaft.

2. Slide the four tines off the shaft.

To Install Tines

1. First slide the inside tines onto each end of the tine shaft. One inside tine is stamped with a "B" and the other is stamped with a "C".

2. Slide the outside tine "A" and tine "D" onto each end of the shaft next. The tines should be installed in the correct order so that they are positioned left to right A, B, C, D, as viewed from the user's position on the mini-cultivator. Make sure that the hub collars on both the right and left pairs of tines face each other so that there is adequate spacing between the tine blades. SEE FIGURE 12.

3. Insert the cotter pins into the holes at each end of the tine shaft to lock the tines into place.

Figure 12 (Front View)

CAUTION

TO AVOID INJURY OR DEATH, NEVER SIPHON FUEL BY MOUTH.
