PART I: General Safety Rules

WARNINGRead this Safety & Operating Instructions manual before you use the LOG SPLITTER. Become familiar with the operation and service recommendations to ensure the best performance of your machine.


The LOG SPLITTER carries prominent labels as reminders for its proper and safe use. Shown below are copies of all the Safety and Information labels that appear on the equipment. Take a moment to study them and make a note of their location on your  LOG SPLITTER as you set up and before you operate the unit. Replace damaged or missing safety and information labels immediately.

Protecting Yourself and Those Around You

WARNINGThis is a high-powered machine, with moving parts operating with high energy. You must operate the machine safely.  Unsafe operation can create a number of hazards for you, as well as anyone else in the nearby area. Always take the  following precautions when using this machine:

  • Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and themselves.
  • 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 sandals.
  • Wear long pants while operating the Log Splitter.
  • Use ear protectors or earplugs rated for at least 20dba to protect your hearing.
  • Keep bystanders at least 50 feet away from your work area at all times. Stop the engine when another person or pet approaches.

Safety for Children and Pets

WARNINGTragic 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. Never assume that children will remain where you last saw them. Always  follow these precautions:

  • 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.

Safety with Gasoline – Powered Machines

WARNINGGasoline 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:

  1. 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.
  2. 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.
  3. Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.
  4. 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.
  5. 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.
  6. 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.
  7. 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 or repairs.
  8. 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.
  9. Keep combustible substances away from the engine when it is hot.
  10. Never cover the machine while the muffler is still hot.
  11. 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.
  12. The muffler and engine become very hot and can cause a severe burn; do not touch.

Operator Zone

Log Splitter

NOTICEAll logs should be no longer than 24″.

WARNINGDo not place your hands on the ends of the log when loading the Log Splitter. This is a very UNSAFE method and could result in injury to your hands. Do not reach or step across the rail while the Log Splitter is running. This is a very  UNSAFE method that could cause personal injury, even death. Do not reach forward and attempt to catch the split wood As the log is being split – let it fall to the ground.CAUTIONNever attempt to split wood across the grain. The Log Splitter was not designed for cross-grain splitting. Doing so could damage the Log Splitter and may cause personal injury. Make sure both ends of the log that you are splitting are cut as square as possible. This will prevent the log from sliding out of position when under pressure

  1. Place the log on the Log Splitter. Grasp the log on the sides near the middle of the block. Center the log, side-to-side, on the rail of the Log Splitter, making sure that one end is against the Splitting Wedge.
  2. With one hand on the Lever and the other hand push the start ball, and then pull the handle lever to the “SPLIT”, and then take away your hands as soon as possible, otherwise, the handle lever will hit your hands when it is retracted from “SPLIT”  to “AUTO-RETRACT”.
