To start the Toro TRX-20 22973HD Trencher, ensure the fuel valve is open, turn the ignition switch to the 'ON' position, and then pull the recoil starter handle firmly.
Regular maintenance includes checking and changing the engine oil, inspecting the air filter, tightening any loose bolts, and checking the condition of the trencher chain and teeth.
If the trencher is not cutting properly, check the condition of the chain and teeth for wear or damage, ensure proper chain tension, and verify that the engine is running at full power.
The Toro TRX-20 22973HD Trencher should be fueled with unleaded gasoline with an octane rating of 87 or higher.
Check the air filter every 25 hours of operation and replace it if it appears dirty or damaged. Always use a genuine Toro replacement part.
Ensure the fuel valve is open, the choke is set properly, and there is enough fuel. Check the spark plug for fouling and replace if necessary.
To adjust the chain tension, first loosen the chain tensioner lock nuts, then turn the tensioner bolts until the chain is properly tensioned. Tighten the lock nuts after adjustment.
Always wear appropriate protective gear, ensure the trencher is on stable ground, and keep bystanders at a safe distance. Be aware of underground utilities before trenching.
Clean the trencher thoroughly, ensure it is stored in a dry place, and drain fuel from the engine if stored for an extended period. Disconnect the spark plug wire to prevent accidental starting.
