Safety
The following is a list of safety rules you must follow in order to use your log
splitter safely.
Personal Protection
✔ To avoid personal injury or death, carefully read and understand all
instructions pertaining to the log splitter, including the engine manufacturer’s
operating and maintenance instruction manual.
✔ Always wear protective gear, such as safety
goggles, tight-fitting gloves without draw-
strings or loose cuffs, steel-toed shoes, and
a protective hearing device.
✔ To prevent injury, make sure all decals are attached to the log splitter and
AR
N
I are legible at all times.

800-817-1005 5Iron & Oak
Worksite Safety
✔ To avoid tripping, do not leave tools, logs, or other components laying around
the work area.
✘ NEVER operate your log splitter on slippery, wet, muddy, or icy surfaces. The
location you choose should be flat, dry, and free from any tall grass, brush,
or other interferences.
✘ NEVER operate the engine in an enclosed area. Exhaust fumes contain car-
bon monoxide that can be deadly when inhaled. Make sure the area is well
ventilated.
✘ NEVER attempt to move your log splitter while the engine is running.
✘ NEVER leave the log splitter running unattended. Shut off engine if you are
going to be away from the log splitter even for a short period of time.
✘ NEVER attempt to move your log splitter over hilly or uneven terrain without a
tow vehicle.
✘ NEVER use your log splitter at night.
✔ ALWAYS operate your log splitter on dry, solid, level ground.
✔ ALWAYS block the wheels to prevent movement of the machine while in
operation.
Operating Safety
✔ ALLOW ONLY ONE (1) PERSON TO LOAD AND OPERATE THE LOG SPLIT-
TER.
✔ Allow only adults to operate the log splitter. No one under the age of 18 should
be allowed to operate the log splitter.
✔ Always keep bystanders, including children and pets, at least twenty-five (25)
feet away from the work area. Only the operator should stand near the
equipment and only within the safe operating area prescribed in this manual
(see the photos on safe and unsafe operating zones in the “Operation”
section).
✔ When the ram of the log splitter is in the return mode, keep your hands off the
machine — the log splitter is designed to automatically stop when the cylinder
is fully retracted.
✔ ALWAYS disconnect the spark plug wire when the log splitter is not in operation.
✘ Do not allow any person to operate the log splitter until they have read and
understood the safe operating instructions contained in this manual.

Iron & Oak

800-817-1005
✘ Do not, under any circumstances, alter your log splitter. This equipment was
designed and engineered to be used in accordance with the operating
instructions. Altering the equipment, or using the equipment in such a way
as to circumvent its design capabilities and capacities, could result in
serious or fatal injury and WlLL VOID THE WARRANTY.
✘ Never operate, or allow anyone else to operate, this equipment while
under the influence of medication, drugs, or alcohol.
✘ Never wear loose clothing or jewelry that may get caught or become
entangled in the log splitter.
✘ NEVER place hands or feet between the log and splitting wedge or between
the log and ram during the forward or reverse stroke.
✘ DO NOT STRADDLE OR REACH ACROSS THE SPLITTING AREA WHEN
OPERATING THE LOG SPLITTER.
✘ Do not step over your log splitter when the engine is running because you may
trip or accidentally engage the ram.
✘ NEVER attempt to load your log splitter while the ram is in motion.
✘ Only use your hand to operate the control lever. NEVER use your foot, knee,
a rope, or any other extension device.
Log Splitting Safety
✔ Always keep your fingers away from any cracks that open in the log during the
splitting operation.
✔ ALWAYS make sure that both ends of the log you are splitting are cut as square
as possible. This will prevent the log from sliding out of position while under
pressure. Logs should be 24 inches or shorter in length.
✘ NEVER try to split two logs on top of each other.
✔ ALWAYS keep full attention on the splitting zone to prevent injury. Hazards
can arise from wood defects (knots, irregular shapes, etc).
✘ Never pile logs to be split in a manner that will cause you to reach across
the log splitter.
Maintenance and Repair
✔ Follow all safety rules, because most accidents involving the operation,
maintenance, or repair of products occur because the
assembler/owner/operator failed to observe basic safety rules or operating
instructions.
✔ ALWAYS inspect your log splitter before each use. Make sure all nuts, bolts,
screws, hydraulic fittings, hose clamps, etc. are securely tightened.

800-817-1005 7Iron & Oak
✔ ALWAYS check the oil level in the hydraulic oil tank and engine reservoir.
✘ NEVER operate your log splitter when it is in need of repair or is in poor
mechanical condition.
✘ NEVER tamper with the engine to run it at excessive speeds. The maximum
engine speed is preset and is within safety limits.
✘ NEVER make alterations to your log splitter in any manner. Such alterations can
cause the log splitter to become unsafe and WILL VOID THE WARRANTY.
✘ NEVER attach a rope or extension to the control lever or add width or height to
the splitting wedge. Such ALTERATIONS can cause the log splitter to become
UNSAFE and WILL VOID THE WARRANTY.
✘ ALWAYS clean the unit after each use. If possible, store the unit inside or cover
it completely, if stored outside.
Towing
✔ ALWAYS check before towing to make certain your log 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 log splitter (see
“Specification” section). Be sure the safety chains are properly hooked to the
vehicle, leaving enough slack for turning.
✔ ALWAYS allow for added length of the log splitter when turning, parking,
crossing intersections, and in all driving situations.
✔ ALWAYS be careful when backing up. You could jackknife your log splitter if
care is not taken.
✔ ALWAYS disconnect your log splitter from your towing vehicle before
attempting to use it.
✘ NEVER exceed 35 mph when towing your log 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 tow your log splitter when there is fuel in the engine’s tank.
✘ NEVER allow anyone to sit or ride on your log splitter.
✘ NEVER carry any cargo or wood on your log splitter.

800-817-1005
Refueling
✔ ONLY refuel the log splitter outdoors in a clear area void of gas fumes or spilled
gasoline.
✔ ALWAYS use an approved fuel container to carry gasoline.
✔ ALWAYS replace the log splitter gas cap and the fuel container cap securely.
✔ If gasoline is spilled, move the machine away from the area of the spill and
avoid creating any source of ignition until the spilled gasoline has completely
evaporated.
✔ Take a class B fire extinguisher with you when operating the log splitter in
dry areas as a precautionary measure against possible flying sparks.
✔ Always store gasoline in an approved, tightly sealed container. Store the
container in a cool, dry place. Do not store the container in a house or near
any heating appliance.
✘ Do not smoke or have open flames when refueling the engine.
Do not spill fuel. If fuel should spill, quickly wipe up the spill and allow
the excess to evaporate before continuing. Make sure gasoline
soaked rags are properly disposed of.
✘ DO NOT fill the gas tank while the engine is hot or running. Allow time for the
engine to cool down before refueling.
Preventing Fires
✘ NEVER operate the log splitter near a flame or spark. Oil and gasoline are
flammable and can explode.
✘ NEVER smoke while operating or refueling the log splitter. Gasoline,
oil, and even gas fumes can explode.
Important Notice
The log splitter is equipped with an internal combustion engine and should not
be used on or near any unimproved forest-covered, brush-covered, or grass-
covered land unless the engine’s exhaust system is equipped with a spark
arrester meeting local or state laws (if any). If a spark arrester is used, it

Iron & Oak 16 800-817-1005
Start-up Procedure
Important Notice
Do not start the engine. Follow all the instructions in the “Start-up
Pro
cedure” before operating the log splitter. Failure to follow this
recommendation will result in engine and hydraulic pump damage.
If this log splitter is purchased without an engine, the customer assumes all liabilities that
might arise from an engine that is incompatible with the design of the log splitter.
Also, any unauthorized changes or modifications to the log splitter will void all warranties.
IMPORTANT: The hydraulic system oil filter for your log splitter is not factory installed.
Make sure the filter is installed before attempting to fill the hydraulic tank or start the
engine. (Installation instructions are also printed on the side of the filter).
IMPORTANT: Before starting the engine, read the engine manufacturer’s operating and
maintenance instruction manual. If an engine manual was not supplied with the log
splitter, it is your responsibility to obtain a manual. Start by contacting the store where
you purchased the log splitter. If they cannot help you, contact the engine
manufacturer.
1. Fill the hydraulic tank with SAE 10W or AW 32 tractor hydraulic oil or automatic trans-
mission fluid, such as Dexron VI, Mercon V, or equivalent. The tank is full when the
oil level is approximately one inch from the top of the tank. Do not tighten the fill cap
at this time.
NOTE: The total hydraulic system oil capacity for this unit is 9.5 gallons.
2. Fill the engine’s crank case with the engine manufacturer’s recommended oil.
3. Lubricate the surface of the slide rail with grease. This will help to prevent wear
between the slide plates and the slide rail.
4. Remove the spark plug wire from the engine. This prevents the engine from starting
until the hydraulic pump and cylinder are completely filled with oil. Make sure the
spark plug wire is held away from the spark plug with string or other nonconductive
material.

800-817-1005

5. Push the valve control handle with one hand to the forward (extend) position (towards
the splitting wedge), and pull the engine starter cord with the other hand
(approximately 15 times) until the cylinder piston moves forward. (Keep everything
away from the pusher plate and wedge during this step).
Cylinder Extend Cylinder Retract
NOTE: Extending the cylinder piston draws the hydraulic fluid through the system and
expels any trapped air in the system.
6. Check the fluid level in the hydraulic tank and add oil as needed.
WARNING
Be careful not to spill fuel when filling the engine. If fuel should spill,
quickly wipe off and allow the excess fuel to evaporate before
continuing. Fuel and fuel vapors are highly flammable and can cause
personal injury or even death when ignited.
Important Notice
If your log splitter is equipped with a factory installed engine, do not mix oil
with the gasoline. Using mixed oil/gasoline in a four cycle engine can cause
