Subaru PKV101 Pump F.A.Q.

How do I start the Subaru PKV101 Pump?

To start the Subaru PKV101 Pump, ensure the fuel valve is open, set the choke to the 'closed' position if the engine is cold, and pull the starter rope gently until resistance is felt, then pull it briskly to start the engine. Once running, gradually adjust the choke to the 'open' position.

What should I do if the pump is not priming?

If the pump is not priming, check for air leaks in the suction line, ensure the check valve is functioning properly, and verify that the pump casing is filled with water. Also, examine the intake hose for blockages or kinks.

How often should I perform maintenance on the Subaru PKV101 Pump?

Regular maintenance should be performed every 50 operating hours or once a month, whichever comes first. This includes checking the oil level, cleaning the air filter, and inspecting the spark plug.

What type of oil should I use for the pump engine?

Use SAE 10W-30 oil for the engine under most temperature conditions. For extreme temperatures, refer to the owner's manual for specific recommendations.

How can I troubleshoot if the pump engine won't start?

If the engine won't start, check for sufficient fuel, ensure the spark plug is clean and properly gapped, verify that the fuel valve is open, and inspect the air filter for blockages.

How do I clean the air filter on the Subaru PKV101 Pump?

To clean the air filter, remove the cover, take out the foam filter, wash it with warm soapy water, rinse thoroughly, and allow it to dry completely before reinstalling. Lightly oil the filter prior to replacement.

What is the correct way to store the pump during the off-season?

For off-season storage, drain the fuel tank and carburetor, change the engine oil, clean the pump thoroughly, and store it in a dry, sheltered location. Cover the pump to protect it from dust and moisture.

Why is the pump losing suction power during operation?

Loss of suction power can be due to air leaks in the suction line, blockages, or a worn impeller. Make sure all connections are airtight and inspect the impeller for wear or damage.

How can I check the spark plug condition?

To check the spark plug, remove it and inspect the electrode gap for wear. The electrode should be light brown. Clean or replace the spark plug if it is fouled or damaged.

What safety precautions should I follow when operating the pump?

Always operate the pump in a well-ventilated area, wear protective gear, and keep flammable materials away from the engine. Ensure all guards and covers are in place, and never refuel while the engine is hot or running.
