Make sure the area below the ram is clear before testing the unit again.⚡ LJ602E Electric Hydraulic Log SplitterUse these steps for the LJ602E electric hydraulic log splitter.Loosen the bleed screw 3 to 4 turns to allow air to go in and out of the oil tank.Check that the log is fixed stably before attempting to split it.Check the oil level. The hydraulic oil needs to be replaced every 150 hours of use. Clean the oil drain bolt and make sure it is tightened to help avoid leakage.Load the log lengthwise into the unit between the wedge and the log pusher.Plug the unit into the correct cord.Use two-hand operation: with the left hand, push the hydraulic lever; with the right hand, push the ON/OFF switch at the same time.Operate the electric splitter for 5 minutes, then switch it off and allow it to cool for 10 minutes before restarting.Important The LJ602E requires the hydraulic lever and ON/OFF switch to be used at the same time. Do not bypass or alter the two-hand operation.🔋 24V-X2-LS6T Battery-Powered Hydraulic Log SplitterUse these steps only for the 24V-X2-LS6T cordless battery-powered hydraulic log splitter.Loosen the bleed screw 3 to 4 turns to allow air to go in and out of the oil tank.Slide both batteries into the battery compartment.Load a single log lengthwise onto the log rail.Begin splitting using two-hand operation: the right hand presses the power button while the left hand pulls the control lever at the same time.Important Make sure both batteries are fully seated before testing the unit. Do not operate the splitter with only one battery installed.🛢️ Hydraulic Oil and Bleed Screw ChecksThe log splitter still will not split after following the correct model section.The ram, wedge, log pusher, control lever, hand wheel, or power switch appears damaged.Hydraulic oil is leaking after the oil drain bolt has been checked and tightened.The unit does not operate after checking power, batteries, cord, or two-hand operation.The splitter does not build pressure or the ram does not move correctly.You are unsure which hydraulic oil, replacement part, or model-specific step applies.Have the model number, serial number, and a description of the issue ready when contacting support.
