Tighten the axle nut and recheck the tension to ensure it remains consistent.

What is the recommended maintenance schedule for a Polaris Timbersled 120 SX?

Perform a thorough inspection before each ride, including checking fluid levels, track condition, and suspension components. Change the oil every 15-20 hours of use, and inspect the drive chain and sprockets for wear regularly. Perform a complete system check every 60 hours or annually.

Why is my Timbersled 120 R making a squeaking noise during operation?

A squeaking noise may indicate dry or worn-out suspension bushings or a misaligned track. Inspect the suspension components for signs of wear and apply lubrication to bushings. Ensure the track is properly aligned and tensioned.

How can I improve the flotation of my Timbersled ARO 137 in deep snow?

Improving flotation involves adjusting the front ski pressure and rear suspension settings. Decrease the ski pressure by adjusting the shocks to softer settings and ensure the rear suspension is set to accommodate the snow conditions. Using a wider ski can also enhance flotation.

What should I do if my Timbersled ARO 3 S won't start in cold weather?

Ensure the battery is fully charged and the fuel is fresh. Use a fuel stabilizer during the colder months. Check and replace the spark plug if necessary, and ensure the carburetor is properly tuned for cold weather conditions.

How do I replace the drive chain on a Timbersled 120 R?

To replace the drive chain, first remove the chain guard. Loosen the tensioner and remove the old chain from the sprockets. Install the new chain, ensuring it fits snugly on the sprockets, then adjust the tensioner to the proper tension. Reinstall the chain guard once completed.

What type of oil should I use for my Timbersled ARO 3 S?

What is the best way to store my Timbersled 120 SX during the offseason?

Clean the entire system thoroughly and apply a protective wax. Drain the fuel tank or add a fuel stabilizer. Store the Timbersled in a dry, cool place and elevate it off the ground to prevent flat spots on the track. Disconnect the battery to prevent discharge.
