Log Splitter: Outdoor hydraulic powered machine that
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 endplates, wedge, and logs while splitting.
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.
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. Some of the components in this unit are
