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 and 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 endplate, 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 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.
Fire Hazards
If your log splitter is intended for use near and ignitable forest, brush, or grassy covered land, the engine exhaust
should be equipped with a spark arrestor. See the "Specifications" section of this manual to determine if your
splitter is equipped already has a spark arrestor. If not equipped, call Northstar Customer Service for ordering
information.
Keep a fire extinguisher with you, that is rated for ordinary combustibles and flammable liquids.
