Why does my QCI LS5T-52 fail to split logs?

  Matthew WebsterAug 8, 2025
  If your QCI Log Splitter fails to split logs, several factors could be at play. First, ensure the log is positioned correctly. If the log's size or hardness exceeds the machine's capacity, reduce the log size. Another potential issue is oil leaks, in which case you should locate the leak(s) and contact the dealer for assistance. Also, contact the dealer if an unauthorized adjustment was made on the Max. Pressure Limiting Screw. Lower max pressure rating was set.

What to do if my QCI LS5T-52 Log Splitter is making unfamiliar noise or vibrating a lot?

  If your QCI Log Splitter is making unfamiliar noises or vibrating a lot, start by loosening the Bleed Screw by 3 ~ 4 rotations before operating the log splitter. Ensure the Oil Drain Bolt with Dipstick is tightened. If the issue persists, it may be due to worn Hydraulic Control Valve Assembly and / or seal(s), in which case you should contact the dealer.

Why does the log pusher move jerkily on my QCI Log Splitter?

  If the log pusher on your QCI Log Splitter moves jerkily, it could be due to a lack of hydraulic oil or excessive air in the hydraulic system. Check the oil level and refill if necessary. Contact the dealer for assistance.
