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:
Moving parts can crush and cut hands and fingers. Keep hands clear of endplate, wedge, log strippers, and logs
while splitting.
High fluid pressures and temperatures are developed in hydraulic log splitters. Hydraulic fluid escaping through
even a pin-size hole 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.
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.
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
