Protecting Yourself and Those Around You
This machine was built to be operated according to the safe operation practices in this manual. As with any type of power
equipment, carelessness or error on the part of the operator can result in serious injury. This machine is capable of
amputating hands and feet and throwing debris. Failure to observe the following safety instructions could result in serious
injury or death.
Many accidents occur when more than one person operates the machine. No helper is allowed to assist in stacking logs.
Operating this Log Splitter safely is necessary to prevent or minimize the risk of death or serious injury. Unsafe operation can
create a number of hazards for you. Always take the following precautions when operating this Log Splitter:
Always wear protective goggles or safety glasses with side shields while using the Log Splitter to protect your eyes from
possible thrown debris.
Avoid wearing loose clothing or jewelry, which can catch on moving parts.
We recommend wearing gloves while using the Log Splitter. Be sure your gloves fit properly and do not have loose cuffs or
drawstrings.
Wear shoes with non-slip treads when using your Log Splitter. If you have safety shoes, we recommend wearing them. Do
not use the machine while barefoot or wearing open toed sandals.
Wear long pants while operating the Log Splitter.
Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing.
Safety for Children and Pets
Tragic accidents can occur if the operator is not alert to the presence of children and pets. Children are often attracted to the
machine and the splitting activity.
precautions:
Never
assume that children will remain where you last saw them. Always follow these
Keep children and pets at least 50 feet from the working area and ensure they are under the watchful care of a responsible
adult.
Be alert and turn the machine off if children or pets enter the work area.
Never allow children to operate the Log Splitter.
Hydraulic Safety
High fluid pressures are developed in hydraulic machines. Pressurized hydraulic fluid escaping through a pin hole opening can
puncture skin and cause severe blood poisoning. Therefore, the following Instructions should be heeded at all times.
Do not operate the unit with frayed, kinked, cracked or damaged hoses, fittings, or tubing. Stop the engine, wait 5 minutes
and relieve hydraulic system pressure by cycling the valve control lever from forward to reverse several times and returning to
neutral while engine is not running before changing or adjusting fittings, hoses, tubing, or other system components.
Do not change any Log Splitter relief valve settings. They are set at the factory for best Splitter performance and safety.
Do not check for leaks with your hand. Leaks can be located by passing cardboard or wood over the suspected area: Look for
discoloration. If injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop if proper medical
treatment is not administered immediately.
Always wear safety glasses to protect your eyes from hydraulic fluid.
NEVER remove the cap from the hydraulic tank or reservoir while the log splitter is running. The tank could contain hot oil
under pressure which could result in serious injury.

Safety with Gasoline - Powered Machines
Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or
explosion. Never overlook the hazards of gasoline. Always follow these precautions:
Never run the engine in an enclosed area or without proper ventilation as the exhaust from the engine contains carbon
monoxide, which is an odorless, tasteless, and deadly poisonous gas.
Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat and open
flame, and out of the reach of children.
Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.
Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Don't handle gasoline if you or
anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the fuel tank cap and
fuel container cap securely and Never remove gas cap while the engine is hot or running.
If you spill gasoline, do not attempt to start the engine. Move the machine away from the area of the spill and avoid creating
any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly
dispose of the waste.
Allow the engine to cool completely before storing in any enclosure. Never store a machine that has gas in the tank, or a fuel
container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.
Never make adjustments or repairs with the engine running. Shut down the engine, disconnect the spark plug wire, keeping it
away from the spark plug to prevent accidental starting, wait 5 minutes before making adjustments, repairs or refueling.
Never tamper with the engine’s governor setting. The governor controls the maximum safe operation speed and protects the
engine. Over-speeding the engine is dangerous and will cause damage to the engine and to the other moving parts of the
machine. If required, see your authorized dealer for engine governor adjustments.
Keep combustible substances away from the engine when it is hot.
Never cover the machine while the muffler is still hot.
Do not operate the engine with the air cleaner or the carburetor air intake cover removed. Removal of such parts could create
a fire hazard. Do not use flammable solutions to clean the air filter.
The muffler and engine become very hot and can cause a severe burn; do not touch.
Towing
ALWAYS check before towing to make certain your Splitter is correctly and securely attached to the towing vehicle. Be sure
that the ball hitch you are using is the proper size for the hitch coupler on the machine. Be sure the safety chains are properly
hooked to the vehicle leaving enough slack for turning.
Always use a Class I, 2” ball with this log splitter and replace the ball or coupler if damaged.
Always confirm coupler tightness each time before towing and after towing 50 miles.
ALWAYS use accessory lights and devices when transporting on a road or highway to warn operators of other vehicles. Check
your local government regulations for DOT information.
ALWAYS allow for added length of the Splitter when turning, parking, crossing intersections, and in all driving situations.
ALWAYS be careful when backing up. You could jackknife your Splitter if care is not taken.
NEVER exceed 45 mph. when towing your Splitter. Obey all state and local regulations when towing on state and local roads
and highways. Adjust your speed for terrain and conditions, as needed. Be extra cautious when towing over rough terrain,
especially over a railroad crossing.
NEVER allow anyone to sit or ride on your Splitter.
NEVER carry any cargo or wood on your Splitter.
Do travel slowly over rough terrain, on hillsides, and around curves to prevent tipping.
Do not tow the Splitter near the edge of a ditch or excavation.
ALWAYS turn the fuel shut off valve on the engine to the “OFF” position before towing the log splitter. Failure to do so may
result in flooding the engine.
