    What to do if my Wen 4019 Pole Saw doesn't start?
    • T
      Theodore BakerJul 27, 2025
      If your Wen Pole Saw doesn't start, there could be several reasons. First, check the power cord, extension cord, power plug, and the power outlet for any damage or improper connection. Do not use the saw if any cord is damaged. It could also be a defective power switch or motor, in which case you should stop using the tool and contact customer service. Another possibility is worn carbon brushes. Have an experienced technician replace them. Replacement brushes (4019-131) can be ordered from wenproducts.com.

      If your Wen Pole Saw doesn't saw properly, vibrates, or jumps up, consider the following: The chain tension may not be adjusted properly, so check and adjust the chain tension. The chain might be dull or worn out, so replace the saw chain. The bar and chain could be installed incorrectly, so reinstall them properly. The saw chain teeth might be pulling in the wrong direction, so remount the saw chain with the teeth in the correct direction.

    Why is my Wen 4019 Pole Saw chain dry?
    • A
      Angela BellAug 6, 2025
      A dry saw chain on your Wen Pole Saw can be due to two main reasons: either there is no oil in the oil tank, in which case you should refill oil, or the oil tube channel is clogged, in which case you should unclog the oil tube.

    Why is my Wen Pole Saw bar and chain becoming too hot?
    • B
      bullockaaronAug 12, 2025
      If the bar and chain of your Wen Pole Saw are getting too hot, it could be due to several reasons: there may be no oil in the tank, so fill the oil tank and frequently check the oil level. The ventilation slots on the motor housing could be clogged, so unclog them. The oil tank tube might be clogged, so unclog the oil tube. Finally, a dull saw chain can cause overheating, so replace the saw chain.
