24-Ton Log Splitter: Hydraulic powered machine that splits wood logs.
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,
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.
Electrical Hazards
FOR USE ONLY with NorthStar Li-Ion Battery Pack item #5043106 and NorthStar Charger item #5050015. Using other batteries or
chargers may result in fire and/or bursting (explosion).
DO NOT operate in a wet environment or expose to rain.
DO NOT operate in extreme temperatures or expose to fire.
DO NOT charge or use if damaged.
DO NOT drop or impact the battery.
DO NOT disassemble, modify, or repair the battery.
DO NOT allow water to contact the battery terminals or get inside the battery.
DO NOT touch the battery connectors with metal objects or insert metal objects through openings into the battery.
DO NOT store battery in damp location. Doing so can cause a malfunction.
Fire Hazards
Keep a fire extinguisher rated "ABC" nearby. Keep it properly charged and be familiar with its use.
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
INSPECT COMPONENTS: Closely inspect to make sure no components are missing or damaged.
