20-Ton Log Splitter: 

Outdoor hydraulic powered machine that

 

splits wood logs.

 

WARNING

 

 

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 Powerhorse Product Support for ordering information. 

• 

Keep a fire extinguisher with you that is rated for ordinary combustibles and flammable liquids. 

 

 

STOP! 

 
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 

INSPECT COMPONENTS:

 Closely inspect to make sure no components are missing or damaged.  

See Initial Unpacking & Set-up for instructions and for whom to contact to report missing or damaged parts.
