ELECTRICAL SAFETY
WARNING! Always check to ensure the power supply corresponds to the voltage on the
rating plate.
Do not abuse the cord. Never use the cord to carry the tool. Keep cord away from heat, oil,
sharp edges or moving parts. Replace damaged cords immediately. Damaged cords may cause
a fire and increase the risk of electric shock.
Grounded tools must be plugged into an outlet properly installed and grounded in
accordance with all codes and ordinances. Never remove the grounding prong or modify the
plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in
doubt as to whether the outlet is properly grounded.
Double insulated tools are equipped with a polarized plug (one blade is wider than the
other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the
outlet, reverse the plug. If it still doesn’t fit, contact a qualified electrician to install a polarized
outlet. Do not change the plug in any way.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and
refrigerators. There is an increase risk of electric shock if you body is grounded.
Never open the switch boxes or motor cover. Never try to do any electrical repairs yourself.
Contact a qualified electrician, or contact a qualified service center for help and information.
IMPORTANT! For additional protection, it is recommended that a GFCI outlet be used.
When operating a power tool outside, use an outdoor extension cord marked “W-A” or
“W.” These cords are rated for outdoor use and reduce the risk of electric shock. Make sure the
extension cord is in good condition before use.
Based on the total length of cord that you are going to use, check the chart to make sure the
cord meets the correct minimum cord gauge (AWG) requirements:
Length in Feet
0 to 50
51 to 100
101 to 150
Gauge (AWG)
14
12

Warning! Using an undersized cord, a less-than-minimum AWG cord, or an excessively long
cord could cause a loss in power (voltage drops). This prevents the motor from developing its full
power and overheats the unit.
Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
Do not let your fingers touch the terminals of plug when installing or removing the plug to or
from the outlet.
Never yank the cord to disconnect it from the socket or outlet; pull from the plug.
Never attempt to move or reposition the log splitter by pulling the cord.
Don’t operate the log splitter with a damaged electrical or extension cord.
Never operate the log splitter unless the power cord is plugged into a properly grounded outlet
that supplies 110-120V power, and a minimum of 8.5 amps of current.
PERSONAL SAFETY
Stay alert, watch what you are doing and use common sense when operating a power
tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or

medication. A moment of inattention while operating power tools may result in serious personal
injury.
Dress properly. Do not wear loose clothing of jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts. Air
vents often cover moving parts and should be avoided.
Always use ANSI Standard Z87.1 eye protection and other safety equipment. Safety
equipment such as dust mask, non-skid safety shoes, hardhat, or hearing protection used for
appropriate conditions will reduce personal injuries.
Avoid accidental starting. Ensure the switch is in the off position before plugging tool into
power outlet.
Do not overreach. Keep proper footing and balance at all times. This enables better control of
the power tool in unexpected situations.
Remove adjusting keys or wrenches before turning the tool on. A wrench or key that is left
attached to a rotating part of the tool may result in personal injury.
The log splitter is to be operated by one person only! Keep in mind that the operator or user is
responsible for accidents or hazards occurring to other people or their property. Always keep
area clear of children, pets, and bystanders.
Never request the assistance of another person to help you remove a jammed log, or for any
other reason.
Don’t allow children incapable people, or people who are not familiar with these instructions to
operate this log splitter.
Always inspect your unit before each use and ensure that handles, guards and fasteners are
secure and in place. Be sure that all electricals cords are not damaged or broken.
Never attempt to use an incomplete machine or one fitted with unauthorized modification. Any
modifications to your machine can cause personal injuries, and will void your Warranty.
Check the log before splitting. It should be free from nails or wire that may fly out during a
splitting operation. This could cause personal injury or damage to the machine. The end of the
log should be cut as squarely as possible.
Never attempt to split more than one log at a time, unless the ram is fully extended, and you
need the second log to complete the split of the first log.
Do not attempt to load the log while the ram of the log splitter is in motion. You could get
trapped and injured.
Keep your hands and body parts away from the open splits and cracks in the log. The wood can
close in suddenly and cause injury.
Do not try to disconnect or override any safety features.
Never leave the machine unattended when in use.
Do not use machine in an area were natural gas, gasoline fumes, dust or flammable liquids are
present.
HYDRAULIC SAFETY
Periodically check for hydraulic fluid leaks by placing a sheet of cardboard under the wood splitter
when system is running.
Warning! Never use your hand or any part of your body to check for hydraulic system leaks
while the system is pressurized. Escaping pressurized fluid can have enough force to penetrate skin
and cause serious injury.
