Instructions for Assembly, Testing, Operation, Servicing, & Storage
Log Splitter: Outdoor hydraulic powered machine that splits wood logs.
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
Keep a fire extinguisher with you that is rated for ordinary combustibles and flammable liquids.
READ YOUR SKID STEER MANUAL TO DETERMINE HOW TO HOOK UP TO SKID STEER
ASSEMBLY REQUIRED: This product requires assembly before use. See "Assembly" section for instructions.
INSPECT COMPONENTS. Closely inspect upon receipt to make sure no components are missing or damaged. See "Assembly"
section for instructions on whom to contact to report missing or damaged parts.
HYDRAULICS: There are many variations of auxiliary hydraulic connections on skid steers. Read your skid steer manual or check
with
your local dealer to determine how to properly connect the log splitter to your skid steer's auxiliary hydraulics.
HYDRAULIC CONNECTION HOSE NOT INCLUDED: You need to provide your own supply and return hoses for connecting
the log splitter to your skid steer's auxiliary hydraulic connections. See p. 10 for instructions on determining the type and length of hoses
you will need.
DETERMINE SKID STEER RPM THAT WILL PRODUCE THE PROPER HYDRAULIC FLOW RATE: Your skid steer's
engine speed will determine the flow rate, and it is unsafe to operate the log splitter at a flow rate higher than 11 GPM. You should read
your skid steer manual in advance to know how to keep the flow rate at or below 11 GPM before you operate the log splitter.
Any Questions, Comments, Problems or Parts Orders
