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, logs, and log strippers 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 an 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 already has a spark
arrestor. If not equipped, call NorthStar Product Support for ordering information.
Keep a fire extinguisher with you that is rated for ordinary combustibles and flammable liquids.
ADD OIL TO ENGINE BEFORE USING: Engine is shipped without oil. DO NOT start log splitter without first adding oil.
ADD HYDRAULIC OIL: Your log splitter was shipped without hydraulic oil. Refer to Periodic Maintenance section of this manual
for instructions on filling the hydraulic reservoir
PRIME THE PUMP: The pump on your log splitter needs to be primed before use. Refer to Initial Setup section for instructions.
INSPECT COMPONENTS: Closely inspect to make sure no components are missing or damaged.
See Initial Unpacking and Set-up for instructions and for whom to contact to report missing or damaged parts.
