Frequently Asked Questions - MS153EMH Maruyama
How do I start the Maruyama MS153EMH pump?
Ensure the fuel tank is filled with unleaded petrol and the oil level is correct. Turn the fuel valve to the ON position, set the choke to the CLOSED position for cold starts, and pull the recoil starter firmly. Once the engine starts, gradually open the choke.
Does the MS153EMH pump require priming before use?
Yes, the pump is not fully self-priming. Before starting, remove the priming plug and fill the pump casing with clean water to allow the impeller to create suction.
What type of oil should I use in the engine?
Use a high-quality 4-stroke engine oil with a viscosity of SAE 10W-30. Check the oil level with the dipstick and change it every 50 hours of operation.
What fuel mixture does the MS153EMH use?
The engine runs on pure unleaded petrol (0-1% ethanol) with an octane rating of 90 or higher. Do not mix oil with the petrol as it is a 4-stroke engine.
How often should I clean the air filter?
The air filter should be checked and cleaned after every 10 hours of use. If operating in dusty conditions, clean it more frequently. Use warm soapy water to wash the foam element and let it dry before re-oiling.
What should I do if the pump delivers low pressure?
Check for air leaks in the suction hose, ensure the strainer is not clogged, and verify that the engine speed is set to the maximum. Also inspect the impeller and seals for wear.
Can I run the pump dry?
No, running the pump without water will damage the mechanical seal. Always ensure the pump casing is filled with liquid before starting.
How do I store the pump after the season?
Drain the fuel from the tank and carburetor, remove the spark plug and add a tablespoon of oil into the cylinder, then pull the starter rope a few times to distribute the oil. Store in a dry, clean place.
Is the MS153EMH pump self-priming?
No, the standard MS153EMH is not self-priming. It must be primed with water each time before starting. However, it can operate on a suction lift of up to 2.5 meters.
Where can I find spare parts for the Maruyama MS153EMH?
Genuine spare parts are available from authorized Maruyama dealers and online shops. Common parts like the spark plug, air filter, and impeller can be easily replaced by following the user manual.
