Poulan Pro S1970 Operator's Manual

To start the Poulan Pro S1970 Chainsaw, first ensure the chain brake is engaged. Set the choke to full and press the primer bulb 6 times. Pull the starter cord until the engine sputters, then set the choke to half and pull again until the engine starts.
The correct fuel mixture for the Poulan Pro S1970 Chainsaw is 40:1, which means 3.2 ounces of 2-cycle oil per gallon of gasoline.
If the chainsaw won't start, check the fuel mixture, ensure the spark plug is clean, and verify that the air filter is not clogged. Also, inspect the ignition coil and primer bulb for any faults.
Regular maintenance includes cleaning the air filter, inspecting and sharpening the chain, checking the chain tension, and ensuring the spark plug is in good condition.
To adjust the chain tension, loosen the bar nuts slightly, then turn the tensioning screw clockwise to tighten and counterclockwise to loosen the chain. Ensure there is no sag and that the chain moves smoothly around the bar.
If the chain keeps coming loose, inspect the chain tensioning mechanism, make sure the bar nuts are properly tightened, and check for any wear on the chain or bar.
Use high-quality bar and chain oil specifically designed for chainsaws to ensure proper lubrication of the chain and bar.
Prevent overheating by ensuring the air intake vents are clean, using the correct fuel mixture, and avoiding prolonged use without breaks to let the engine cool down.
If the chain cuts crooked, check the chain for uneven sharpening and inspect the guide bar for wear. Ensure the chain tension is even and the bar is not bent.
For storage, clean the chainsaw thoroughly, remove any fuel from the tank, and store it in a dry, cool place. Consider applying a protective oil to the chain and bar to prevent rust.
