Instructions for Assembly, Testing, Operation,
Servicing, & Storage
Log Splitter: Outdoor hydraulic powered machine that
splits wood logs.
WARNING
READ and UNDERSTAND this manual completely before using log splitter.
All operators of this equipment must read and completely understand all safety information, operating instructions,
maintenance and storage instructions. Failure to properly operate and maintain the log splitter could result in serious
injury to the operator or bystanders from moving parts that can crush or cut, flying objects, burns, fire or explosion,
escaping high pressure hydraulic fluid, or carbon monoxide poisoning. In particular, be aware of the following
hazards:
Crush and Cut Hazards
Moving parts can crush and cut hands and fingers. Keep hands clear of endplates, wedge, and logs while splitting.
High Pressure Hydraulic Fluid Hazards
High fluid pressures and temperatures are developed in hydraulic log splitters. Hydraulic fluid escaping through
even a pin-size hold opening can puncture skin and cause severe blood poisoning. Inspect hydraulic system
regularly for possible leaks. Never check for leaks with your hand while the system is pressurized. Seek medical
attention immediately if injured by escaping fluid.
Fire Hazards
If your log splitter is intended for use near any ignitable forest, brush, or grassy covered land, the engine exhaust
should be equipped with a spark arrestor.
Keep a fire extinguisher with you, rated for ordinary combustibles and flammable liquids.
STOP!
ASSEMBLY REQUIRED: This product requires assembly before use. See “Assembly” section for instructions.
INSPECT COMPONENTS. Closely inspect upon receipt to make sure no components are missing or damaged. See
“Assembly” section for instructions on whom to contact to report missing or damaged parts.
ADD ENGINE OIL and HYDRAULIC OIL BEFORE USING: This product is shipped without
engine oil or
hydraulic oil. DO NOT start log splitter before adding both oils. See “Assembly” and “Initial Unpacking & Set-
up” sections for detailed instructions.

Questions and Answers

    Why is my Powerhorse Log Splitter splitting wood so slowly?
    • B
      Bradley ColeAug 5, 2025
      If your Powerhorse Log Splitter's wood splits extremely slowly or not at all, several issues could be the cause. First, check the oil level in the reservoir, as insufficient oil or air in the oil can cause this. Also, inspect the pump inlet hose for blockages or kinks that might be causing excessive pump inlet vacuum. If the control valve setting is low, adjust it using a pressure gauge. For internal control valve leaks or an internally damaged cylinder, it is recommended to return the control valve or cylinder for authorized repair.

    How to fix slow cylinder shaft speed on Powerhorse Log Splitter?
    • E
      Elizabeth HernandezAug 11, 2025
      If the cylinder shaft speed of your Powerhorse Log Splitter is slow when extending or retracting, start by checking the oil level in the reservoir, as insufficient oil or air in the oil could be the cause. Also, inspect the pump inlet hose for any blockages or kinks, as these can cause excessive pump inlet vacuum. Check and tighten hose clamps on suction hose if it’s drawing air through the suction line. If the issue persists, the control valve or cylinder may be damaged internally, requiring you to return them for authorized repair.

    How to troubleshoot a Powerhorse Log Splitter cylinder rod that won't move?
    • D
      Debra SimmonsAug 25, 2025
      If the cylinder rod on your Powerhorse Log Splitter won't move, it could be due to several reasons. Start by checking the oil level in the reservoir, as insufficient oil can cause this. Also, inspect the hydraulic lines and control valve for blockages, and flush and clean the splitter hydraulic system if necessary. If the control valve or cylinder piston is damaged, it is recommended to return these components for authorized repair.

    What causes a Powerhorse M11571I Log Splitter engine to stall under low load?
    • A
      Angela PaulAug 29, 2025
      If your Powerhorse Log Splitter engine stalls under low load condition, the hydraulic lines or control valve might be blocked. To resolve this, flush and clean the splitter hydraulic system.
