How to Troubleshoot a Tru Cut Lawnmower

Start the Tru Cut lawnmower properly. Press the priming bulb two or three times, push the blade control handle against the handle bar and pull the starter rope. Do not prime the engine if it is warm from prior use. Let the engine rest a few minutes before attempting to restart a flooded engine.

Inspect the spark plug and spark plug wire. Reconnect the wire if it is off the spark plug. Clean the spark plug and replace it if it’s damaged or doesn’t spark. A lawnmower with a spark plug that is damaged, has a poor connection or doesn’t spark will refuse to start, run poorly or hesitate while working.

Check the fuel, fuel tank, lines and fuel tank cap. Fill the tank if it is low or empty. Check the fuel lines and clean them if they are blocked. If the fuel is contaminated with water or debris, empty the tank and carburetor and refill the tank with clean fuel. Clean the vent on the fuel cap so the air flows freely. Fuel that is stale, contaminated or blocked prevents the Tru Cut lawnmower from starting or running properly.

Examine the air filter. Clean the air filter if it is dirty or replace it if it’s damage. A dirty or damaged air filter will cause the Tru Cut mower to run and idle poorly.

Check the oil. Fill the tank or change the oil it if is dirty or old. Low levels of oil can cause the engine to overheat.

Check the blower housing. Clean the clean blower housing to prevent blockages which can cause the engine to overheat.

Inspect the cutting blades. If they are bent, dull, damaged, or unbalanced they need to be repaired or replaced. Substandard blades will prevent the Tru Cut machine from mulching, cause excessive vibration, or cause the mower to cut unevenly.

Adjust the carburetor if it is out of adjustment. A poorly adjusted carburetor causes the engine to run poorly or overheat.

Set the cutting height adjustment levers, located next to each wheel, to the same height to prevent uneven cuts.
