GENERAL SAFETY INFORMATION
DANGER! GENERAL SAFETY: Failure to follow warnings, cautions, assembly and operation
instructions in the User Manual may result in serious injury or death.
DANGER! READ THE USER MANUAL BEFORE OPERATION
• Do not permit children to operate this equipment at any time. Do not permit others that
have not read and understood the complete User Manual to operate this equipment.
• Keep all people and pets a minimum of 10 feet away from the work area when operating
this machine. Only the operator is to be near the machine during use.
• Do not operate the machine when under the influence of alcohol, drugs, or medication.
• Do not allow a person who is tired or otherwise impaired or not completely alert to
operate this machine.
DANGER! PREPARATION OF THE LOG: Both ends of the log should be cut as square as
possible to prevent the log from rotating out of the splitter during operation. Do not split
logs greater than 20.5” (52.1 cm) in length.
DANGER! WORK AREA
• Do not operate the machine on icy, wet, muddy or otherwise slippery ground. ONLY
operate your machine on level ground. Operating on a slope could cause the machine
to roll over or logs to fall o of the equipment, which could result in injury.
• Do not operate the log splitter in an enclosed area.
• Do not move the machine over hilly or uneven terrain without a tow vehicle or adequate
help.
• Use a tire chock or block on wheels to prevent movement of the log splitter while in
operation.
• Operate the log splitter in daylight or under good artificial light.
• Keep the work area free of clutter. Remove split wood from around the log splitter
immediately after each use to avoid potential tripping.
WARNING! CRUSH HAZARD: The wedge is dangerous, keep all limbs away from the
wedge and endplate at all times during operation. Failure to follow this instruction can lead
to serious injury.
WARNING! High-pressure hydraulic oil can break skin and cause severe injury. Make sure
all fittings are seated firmly and tightly secured before applying pressure. Relieve system
of pressure before servicing.
DANGER
• Make sure the operator knows how to stop and disengage the controls before
operating.
• Do not place hands or feet between the log and splitting wedge during forward or
reverse stroke. Serious injury or death could result.
• Do not straddle or step over the log splitter during operation.
• Do not reach or bend over the log splitter to pick up a log.
• Do not attempt to split two logs on top of each other.
ENGLISH

12 | OPS220EV man.
• Do not attempt to cross split a log.
• Do not Attempt to load your log splitter when the ram or wedge is in motion.
• Use your hand to operate the control lever on the valve. Do not use your foot, a rope
or any extension device.
• Do not move the log splitter while the motor and/or battery are running
• Never leave the equipment unattended while the motor and/or battery are running.
Shut o the motor and battery even if you are leaving the log splitter for a short period
of time.
• Avoid contact with hot areas of the machine during operation or after running to prevent
burns.
WARNING! REPAIR AND MAINTENANCE
• Do not operate the log splitter when it is in poor mechanical condition or in need of
repair. Frequently check that all nuts, bolts, screws, hydraulic fittings and hose clamps
are tight.
• Do not alter the log splitter in any manner. Any alteration will void the warranty
and could cause the log splitter to be unsafe to operate. Perform all recommended
maintenance procedures before using the log splitter. Replace all damaged or worn
parts immediately.
• Do not tamper with the motor and/or battery to run at excessive speeds. The maximum
engine speed is preset by the manufacturer and is within safety limits.
• Turn o the motor and battery before performing any service or repair on the log splitter.
• Always check the level of hydraulic oil before operation.
• Replacement parts must meet manufacturer’s specifications.
WARNING! HYDRAULIC SAFETY: The hydraulic system of the log splitter required careful
inspection along with the mechanical parts. Be sure to replace frayed, kinked, cracked or
otherwise damaged hydraulic hoses or hydraulic components.
• Check for hydraulic fluid leaks by passing a piece of paper or cardboard underneath
or over the area of the leak. Do not check for leaks with your hand. Fluid escaping
from the smallest hole, under pressure, can have enough force to penetrate the skin
causing serious injury or death.
• Seek professional medical attention immediately if injured by escaping hydraulic
fluid. Serious infection or reaction can develop if medical treatment is not administered
immediately.
• Relieve all pressure by shutting o the motor and battery and moving the valve control
handle back and forth should it become necessary to loosen or remove any hydraulic
fitting.
• Do not 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.
• Do not adjust the hydraulic valve. The pressure relief valve on the log splitter is preset
at the factory. Only a qualified service technician should perform this adjustment.
CAUTION! FIRE PREVENTION
• Do not operate the log splitter near an open flame or spark. Hydraulic oil is flammable
and can explode.
ENGLISH

v.230116 | 13
• Do not fill the hydraulic oil while the motor and battery are running. Allow the motor and
battery to rest and cool before refueling.
• Do not smoke while operating or refueling the log splitter. Hydraulic fluid is flammable.
• Keep a Class B fire extinguisher on hand when operating this log splitter in dry areas as
a precautionary measure against possible flying sparks.
WARNING! TOWING SAFETY
• This product is intended for o-road ATV or lawn tractor towing ONLY at a maximum
tow speed of 15 mph (24 km/h). This machine is NOT meant for street towing.
• Check before towing to make sure that the log splitter is correctly and securely attached
to the towing vehicle.
• Do not carry any cargo or wood on the log splitter.
• Do not allow anyone to sit or ride on the log splitter.
• Disconnect the log splitter from the towing vehicle before operating it.
• Use care when backing up with the log splitter in tow to avoid jack-knifing. Allow for
added length of the log splitter during transport.
• Do not exceed 15 mph (24 km/h) when towing your log splitter. Towing the log splitter
at speeds higher than 15 mph (24 km/h) could result in loss of control, damage to the
equipment, serious injury, or death. Adjust towing speed for terrain and conditions. Be
extra cautious when towing over rough terrain.
CALIFORNIA PROPOSITION 65 WARNING: Petroleum products (hydraulic fluid) can
expose you to chemicals including toluene and benzene, which are known to the State
of California to cause cancer and birth defects or other reproductive harm. Read more at
