To start the Husqvarna 135 Mark II, first ensure the chain brake is engaged. Move the choke lever to the full choke position. Pull the starter handle until the engine fires, then move the choke to the half position and pull again until the engine starts. Once running, accelerate slightly to disengage the choke.
The Husqvarna 135 Mark II Chainsaw requires a mixture of unleaded gasoline and two-stroke oil, with a recommended ratio of 50:1. Use high-quality oil that meets the specifications for air-cooled engines.
To maintain proper chain tension, loosen the bar nuts slightly and use the chain tensioning screw to adjust the chain until it fits snugly against the bar but can still be moved by hand. Retighten the bar nuts once the tension is correct.
If your chainsaw won't start, check the fuel mixture and ensure fresh fuel is used. Inspect the spark plug for damage or fouling, and clean or replace it if necessary. Ensure the air filter is clean and the choke is in the correct position.
The air filter should be checked and cleaned after every 5 hours of operation or more frequently in dusty conditions. Use warm soapy water to clean it and allow it to dry completely before reinstalling.
To sharpen the chainsaw chain, use a round file and filing guide that matches the chain's specifications. File each cutter at a consistent angle and depth, typically 30 degrees. Ensure even sharpening on all cutters for optimal performance.
For proper storage, clean the chainsaw thoroughly and empty the fuel tank. Run the engine until it stops to clear any remaining fuel. Store the chainsaw in a dry, cool place, away from direct sunlight.
If the chain is not cutting properly, check the sharpness of the chain and sharpen it if necessary. Ensure the chain tension is correct and that the bar is not worn or damaged. Verify that the chain is installed in the correct direction.
Excessive vibration can be caused by a loose chain, worn bar, or damaged anti-vibration mounts. Check and tighten the chain, replace the bar if necessary, and inspect the mounts for wear or damage.
The spark plug should be inspected and cleaned regularly, and replaced every season or after 100 hours of use, whichever comes first. Use a spark plug that meets the manufacturer's specifications.
