MAINTENANCE AND SAFETY
• The mechanical and hydraulic systems of the log splitter require careful inspection. Be sure to replace any damaged
hydraulic hoses or components immediately to ensure safe operation of the log splitter.
• NEVER check for leaking hydraulic fluid by using your hands. Leaking hydraulic fluid under pressure can potentially
penetrate the skin causing SERIOUS INJURY or even DEATH. Leaks can be safely detected by holding a piece of
cardboard over the suspected leak and looking for discoloration.
• NEVER remove the cap from the hydraulic tank while the log splitter is running. The tank contains hot oil under
pressure which could cause serious injury if released from the tank.
• NEVER adjust the relief valve setting on the log splitter. The pressure relief valve on the log splitter is preset by the
manufacturer. Only a qualified service technician should perform any adjustments.
• ALWAYS immediately seek medical attention if injured by escaping hydraulic fluid. Serious infections or reactions
can develop if proper medical treatment is not quickly administered.
• ALWAYS check the system is not under any pressure by shutting off the engine and moving the valve control handle
back and forth. Check for pressure before loosening or removing any hydraulic fitting.
• ALWAYS keep the beam and wedge free of debris buildup.
FIRE PREVENTION
• ONLY refuel the log splitter in clear areas with no gas fumes and no spilled gas.
• NEVER operate the log splitter near flames, sparks or smoke. Hydraulic oil and gasoline are flammable and
potentially explosive.
• NEVER add fuel to the log splitter while the engine is hot or running. Allow the engine to cool completely before
refueling.
• If gasoline spills, move the log splitter away from the area of the spill and avoid creating any source of ignition.
• ALWAYS securely replace the gas cap.
• ALWAYS clean wood debris from the muffler area of the engine.
• ALWAYS store gasoline in an appropriate, tightly sealed container. Store the gas container in a cool, dry place and
away from any heat sources.
IMPORTANT NOTE: SPARK ARRESTOR-REGULATION:
As a precautionary measure against possible flying sparks, always have a Class B fire extinguisher on hand when
operating the log splitter in dry areas. The log splitter is equipped with an internal combustion engine that generates
heat and potential flying sparks. Only use the log splitter on or near any unimproved, forest-covered, brush-covered or
grass-covered land if the engine’s exhaust system is equipped with a spark arrester in compliance with any applicable
local or state laws. Spark arresters should be effectively maintained and serviced. In the state of California, a spark
arrester is required by law and other states have similar laws. Federal laws will apply when operating the log splitter
on federal land. Always research and comply with applicable state, local and federal laws and regulations. A spark
arrester muffler is optional and available as an accessory at your nearest engine dealer.
SAFE TRANSPORT
• NEVER tow the log splitter behind a vehicle as the wheels and log splitter orientation are incompatible with towing.
Attempting to tow the log splitter may damage or destroy the wheels or other parts of the log splitter.
• To safely transport the log splitter secure it on top of a trailer or other transporting vehicle.
• NEVER move the log splitter over hilly or uneven terrain without the proper vehicle and adequate help for safe
movement.
• NEVER exceed the weight capacity of hitch or load limits of the transporting vehicle.
• ALWAYS use caution when transporting the log splitter and check carefully that the log splitter is securely attached
to the transporting vehicle.
• ALWAYS confirm hitch accessory tightness before and after transporting the log splitter.
• ALWAYS disconnect the log splitter from the carrying vehicle before operating.
• ALWAYS check for and replace a damaged hitch.
• ALWAYS turn the fuel shut off valve on the engine to the “OFF” position before transporting the log splitter. Failure
