IMPORTANT SAFETY INSTRUCTIONS
Fuel Safety
DANGER
GASOLINE AND GASOLINE VAPORS ARE HIGHLY
FLAMMABLE AND EXPLOSIVE.
Fire or explosion can cause severe burns or death.
Gasoline and gasoline vapors:
–Gasoline vapors are highly flammable and explosive.
–Gasoline vapors can cause a fire or explosion if ignited.
–Gasoline is a liquid fuel and the resulting gasoline vapors can
ignite and cause a fire or explosion.
–Gasoline is a skin irritant and needs to be cleaned up
immediately if spilled on skin or clothes.
–Gasoline has a distinctive odor, this will help detect potential
leaks quickly.
–In any petroleum gas fire, flames should not be extinguished
unless by doing so the fuel supply valve can be turned OFF.
This is because if a fire is extinguished and a supply of fuel is
not turned OFF, then an explosion hazard could be created.
–Gasoline vapors expand and contract with ambient
temperatures. Never fill the gasoline tank past the red FULL
indicator on the fuel filter, as gasoline vapors needs room to
expand if temperatures rise.
WARNING
When adding or removing gasoline:
Do not light or smoke cigarettes.
Always stop the engine and allow to cool for a minimum of two
minutes before refueling.
Always loosen gasoline cap slowly to release vapor pressure
and to keep fuel from escaping around the gasoline cap.
Always replace and tighten the gasoline cap securely after
fueling.
Never remove the gasoline cap or add gasoline while the
engine is running or when the engine is hot.
Only fill or drain gasoline outdoors in a well-ventilated area.
Do not pump gasoline directly into the log splitter at the gas
station.
Always store gasoline in an EPA/CARB compliant container or
to transfer the gasoline to the log splitter.
Do not overfill the gasoline tank.
Always keep gasoline away from sparks, open flames, pilot
lights, heat and other sources of ignition.
WARNING
When starting the log splitter:
Do not attempt to start a damaged log splitter.
Always check that the gasoline cap, air filter, spark plug, fuel
lines and exhaust system are properly in place.
Always allow spilled gasoline to evaporate fully before
attempting to start the engine.

2. Remove the plastic shipping plug from the oil tank on the top
of the tank (A) and discard. Replace with the steel oil plug
(with breather hole) shipped with your log splitter (A).
CAUTION
Do not run the log splitter with the temporary oil tank shipping
plug.
Pressure will build up inside the tank and potential damage
could occur.
3. After running and cycling the unit several minutes (purging air
from the system), turn off the engine and check the hydraulic
oil level using the oil sight glass. Oil level should visibly fill the
glass sight.
If your log splitter was delivered unassembled, follow these
instructions:
1. Make sure the log splitter is on a flat, level surface.
2. Remove the oil plug from the oil tank (A).
3. Add 4 gal (15.1 L) of hydraulic oil - see specification section
for types of acceptable oil.
4. Check the hydraulic oil level using the oil sight glass.
Oil level should visibly fill the sight glass.

WARNING
DO NOT remove the hydraulic oil fill cap when the engine
is running or hot. Hot oil can escape causing severe burns.
Always allow the log splitter to cool completely before
removing the hydraulic oil cap.
High fluid pressure and temperatures are created in the
hydraulic log splitters. Hydraulic fluid will escape through a
pin-size hole opening and can puncture skin and cause severe
blood poisoning.
Inspect hydraulic system regularly for possible leaks.
Never check for leaks with your hand while the system is
pressurized. Seek medical attention immediately if injured by
escaping fluid.
5. Replace and tighten the oil plug and orient the vent hole away
from the operator zone.
6. Start Engine. (See Starting the Engine section)
7. Extend and retract the wedge to purge air from the hydraulic
system. When the wedge motion is smooth,
the system is properly purged.
8. Check the hydraulic oil tank sight glass. Add approximately
0.5 gal. (1.9 L) of hydraulic oil to bring the level back up to the
sight glass. Do NOT overfill.
9. Check oil level daily and add as needed.
NOTICE
When the outdoor temperature is below 32˚F (0˚C), Dexron III
transmission fluid can be used. Do not mix hydraulic oil and
transmission fluid. Drain all oil or fluid before adding the other
one.
See hydraulic oil system specifications section for more
details.
NOTICE
To check oil level, place on level surface and use the oil sight
glass on the tank. The oil sight glass has a marker for the
acceptable level of oil. If oil is below the marker, add oil as
needed. DO NOT OVERFILL.

OPERATION
Before Each Use Inspect the Log Splitter
1. Check the hydraulic oil level and visually inspect all hoses,
attachments and cylinder for loose fittings, leaks, cracks,
fraying or other damage.
2. DO NOT operate the log splitter if there is any indication of
damage.
3. Inspect the engine and make sure the oil level is correct
before operating. If the engine is equipped with a spark
arrestor, clean and inspect it regularly (follow spark arrestor
maintenance schedule).
4. The tires need to be fully inflated and in good repair.
Reference the tire sidewall for recommended tire pressure.
WARNING
DO NOT over inflate tires. Serious injury can result if tires
explode.
DO NOT tow the log splitter if the tires are worn or will not hold
air.
DO NOT exceed the maximum 45 MPH (72 KM/H) towing
speed.
Changing Beam from Horizontal to Vertical
Orientation
When logs are too heavy to lift, log splitter beam can be moved
from horizontal to vertical orientation.
To change from horizontal to vertical orientation:
1. Block the wheels to prevent the unit from rolling.
2. Pull the spring loaded pin out on the horizontal beam lock
attached to the tow bar to release the beam. Standing
alongside the hydraulic ram, (opposite side from the engine)
firmly grasp the handle on the beam and lift upward while
pushing the beam back until upright. (Caution, beam is
heavy.)
3. Pull out the spring loaded quick-lock pin and rotate it around
to the 9 o’clock position around the lip on the beam to secure
it in the vertical position.
4. To change from vertical to horizontal orientation, reverse the
steps. The beam will automatically lock into the auto-lock on
the tow bar when lowered into position.

OPERATION
Towing Log Splitter Safety
1. Always check local, state or provincial regulations regarding
towing, licensing and lights before towing your log splitter.
Review towing safety warnings in your towing vehicle manual.
2. Before towing make sure the log splitter is correctly and
securely attached to the vehicle and the safety chains
attached with enough slack to allow for turning.
3. Support leg must be pinned in the “UP” position for towing.
4. Never exceed the max. travel speed of 45 mph (72 km/h).
Towing the log splitter at speeds greater than 45 mph
(72 km/h) could result in serious injury or death. Always
adjust your towing speed according to the terrain and
conditions.
5. Always disconnect the log splitter from the towing vehicle
before operating.
Log Splitter Location
This log splitter must have at least seven feet of clearance from
combustible material. Leave at least three feet of clearance on all
sides of the log splitter to allow for adequate cooling, maintenance
and servicing. DO NOT place the log splitter near vents or intakes
where engine exhaust fumes could be drawn into occupied or
confined spaces. ONLY operate the log splitter outdoors.
The log splitter needs to be on a dry level surface with good
footing. DO NOT work on mud, ice, tall grass, brush or snow.
Only operate log splitter from work zone shown below.

WARNING
ALWAYS use the log splitter for its intended use. The log
splitter should only be used to split wood logs, length wise
with the grain.
NEVER modify, alter or change the log splitter in anyway.
Modifications will void the warranty.
NEVER attach a rope, cable or other device to the control lever
on the log splitter.
DO NOT modify or change the engine and operating speeds or
pressure settings. These changes can cause safety issues.
ONLY operate the log splitter in daylight.
NEVER operate, or let anyone else operate the log splitter

Log Splitter Operation
1. ALWAYS wear ear and eye protection, protective clothing and
safety gear.
2. Block tires and ensure support leg is secure to prevent
unintended movement of the log splitter during operation.
3. Set log splitter in either the horizontal or vertical position.
NOTICE
HORIZONTAL position is used for lighter logs that can easily be
loaded onto the beam.
VERTICAL position is used for light logs as well as heavy logs
that are difficult to load onto the beam.
Back injury can result from lifting logs onto the log splitter if
proper lifting techniques are not used.
4. Load a log onto the beam against the end plate
(MAX LOG LENGTH – 24 in. [61 cm]).
5. To stabilize the log, place your left hand on the side of the log.
Vertical Horizontal
WARNING
Never place your hand on the ends of the log, between the log
and end plate or the log and the splitting wedge.
WARNING
Only one operator permitted. The adult who loads and
stabilizes the log, must be the person who operates the control
handle.
6. Make sure all limbs are clear of crush zones.
7. Use your right hand to push the control valve handle forward
(towards the end plate) to split the log.
8. Remove left hand from the log once the wedge begins to
contact with the log. Continue holding the control handle in
the forward position until the log splits.
9. Push the auto control valve handle backward to return the
wedge to its original position.
10. Clear the split wood from the work zone.
NOTICE
It is normal for the hydraulic fluid to appear foamy/frothy
during operation. This can be caused by agitated oil in the tank
collecting air.
NOTICE
If a log gets stuck, embedded or will not split completely,
push the control handle in the reverse direction and allow the
splitter to strip the log from the wedge.
ALWAYS keep hands clear of the log and wedge while it is
retracting.
NOTICE
The cylinder stroke is designed so the wedge stops
approximately 1.5 in. (3.8 cm) from the end plate.
