Add Engine Oil
1. Make sure the log splitter is on a flat, level surface.
2. Remove oil fill cap/dipstick to add oil.
3. Add up to 0.42 qt (0.4 L) of oil. Replace oil fill cap/
dipstick. DO NOT OVERFILL.
4. Check engine oil level daily and add as needed.
DO NOT attempt to crank or start the engine before
it has been properly filled with the recommended
type and amount of oil. Damage to the log splitter
as a result of failure to follow these instructions will
void your warranty.
CAUTION
The engine is equipped with a low-oil-shutoff and
will stop when the oil level in the crankcase falls
below the threshold level.
CAUTION
Check oil often during the break-in period. Refer to
the Maintenance section for recommended service
intervals.
NOTE
Add Fuel Cont’d.
Our engines work well with 10% or less ethanol blend
fuels. When using blended fuels there are some issues
worth noting:
– Ethanol-gasoline blends can absorb more water than
gasoline alone.
– These blends can eventually separate, leaving water
or a watery goo in the tank, fuel valve and carburetor.
– With gravity-fed fuel supplies, this compromised fuel
can be drawn into the carburetor and cause damage
to the engine and/or potential hazards.
– There are only a few suppliers of fuel stabilizer that
are formulated to work with ethanol blend fuels.
– Any damages or hazards caused by using improper
fuel, improperly stored fuel, and/or improperly
formulated stabilizers, are not covered by
manufacture’s warranty.
It is advisable to always shut off the fuel supply, run the
engine to fuel starvation and drain the tank when the
equipment is not in use for more than 30 days.
NOTE
Add Fuel
1. Use clean, fresh, regular unleaded fuel with a
minimum octane rating of 85 and an ethanol
content of less than 10% by volume.
2. DO NOT mix oil with fuel.
3. Clean the area around the fuel cap.
4. Remove the fuel cap.
Use regular unleaded gasoline with a minimum octane
rating of 85.
Do not mix oil and gasoline.
Fill tank to approximately ¼ in. (0.64 cm) below the top of
the tank to allow for fuel expansion.
DO NOT pump gas directly into the generator at the gas
station. Use an approved container to transfer the fuel to
the generator.
DO NOT fill fuel tank indoors.
DO NOT fill fuel tank when the engine is running or hot.
DO NOT overfill the fuel tank.
DO NOT light cigarettes or smoke when filling the fuel tank.
CAUTION
Pouring fuel too fast through the fuel screen may
result in blow back of fuel at the operator while filling.
WARNING
5. Slowly add fuel to the tank. DO NOT OVERFILL.
Fuel can expand after filling. A minimum of ¼ in.
(0.64 cm) of space left in the tank is required
for fuel expansion, more than ¼ in. (0.64 cm) is
recommended. Fuel can be forced out of the tank
as a result of expansion if it is overfilled, and can
affect the stable running condition of the product.
When filling the tank, it is recommended to leave
enough space for the fuel to expand.
6. Screw on the fuel cap and wipe away any spilled fuel.

11 REV 90720-20130226
ENGLISH 90720
ASSEMBLY
6. Replace and tighten the dipstick.
7. Start engine (see Starting the Engine in the
Operation section).
8. Extend and retract the cylinder to purge air from the
hydraulic system. Cylinder motion should be smooth
and continuous.
9. Shut-off engine (see Stopping the Engine in the
Operation section).
10. Check the hydraulic oil tank dipstick. Add additional
hydraulic oil if needed.
11. Check oil level daily and add as needed.
When the outdoor tempurature is below 32 ˚F,
Dexron III transmission fluid can be used.
NOTE
To check oil level, insert the dipstick into fill neck
until it stops. Remove and read level. Do not thread
dipstick into fill neck when checking oil.
NOTE
Always tighten the hydraulic vent screw when the
engine is off and log splitter is not in use. When
the vent screw is closed, it prevents dust, dirt, and
debris from entering the tank. Closing the vent
screw also prevents oil leakage when the log splitter
is being transported.
NOTE
While the hydraulic vent screw is open, some
hydraulic oil may spill out during transportation
and/or operation especially if the log splitter is not
on a level surface.
NOTE
Failure to open the hydraulic vent screw will
cause pressure build-up due to heat. This creates
difficulty during maintenance and operation.
NOTE
Add Hydraulic Oil
1. Make sure the log splitter is on a flat, level surface.
2. Remove the dipstick from the oil tank. (A)
3. Using your fingers, open the hydraulic vent screw by
turning it counter clockwise approximately 2-3 times.
(B)
4. Add 0.87 gal. (3.3 L) of hydraulic oil - 10W AW32,
ASLE H-150, or ISO 32.
5. Check the hydraulic oil level using dipstick. Oil level
should be between the two marks on the dipstick.
(A)
DO NOT remove the dipstick 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
dipstick. 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.

OPERATION
Starting the Engine Cont’d.
Starting the Engine
1. Make certain the log splitter is on a flat, level
surface.
2. Using your fingers, open the hydraulic vent screw by
turning it counter clockwise approximately 2-3 times.
3. Flip engine switch to “ON” position (Item A).
4. Rotate the fuel valve to the “ON” position (Item B).
5. Move the throttle lever (Item C) to the “Fast”
position.
6. Move the choke lever (Item D) to the “Choke”
position.
7. Pull the starter cord slowly until resistance is felt and
then pull rapidly. SEE NOTE BELOW.
8. As engine warms up, move the choke lever (Item D)
to “Run.”
If the engine starts but does not run make certain
that the log splitter is on a flat, level surface. The
engine is equipped with a low oil sensor that will
prevent the engine from running when the oil level
falls below a critical threshold.
The hydraulic oil needs to be above 10° F (-12° C)
before starting the engine. Cold hydraulic oil can
damage the hydraulic pump.
If outdoor air temperature is below 32° F (0° C)
allow the log splitter to warm up by extending and
returning the wedge several times before splitting
wood.
NOTE
A
B
C
D
Keep choke lever in “Choke” position for 2 pulls
of the recoil starter. After second pull, move choke
lever to the “Run” position for up to the next 3
pulls of the recoil starter. Too much choke leads to
spark plug fouling/engine flooding due to the lack of
incoming air. This will cause the engine not to start.
NOTE
Stopping the Engine
1. Turn the fuel knob to the “Off” position. (B)
2. Let the engine run until fuel starvation has stopped
the engine. This usually takes a few minutes.
3. Turn the engine switch to the “Off” position. (A)
4. Using your fingers, tighten the hydraulic vent screw
by turning it clockwise approximately 2-3 times.
Important: Always ensure that the Fuel Valve and the
Engine Switch are in the “OFF” position when the
engine is not in use.
If the engine will not be used for a period of two (2)
weeks or longer, please see the Storage section for
proper engine and fuel storage.
NOTE
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.

Log Splitter Operation Cont’d.
OPERATION
Back injury can result from lifting logs onto the log
splitter if proper lifting techniques are not used.
CAUTION
It is normal for the hydraulic fluid to become foamy
or frothy during operation.
NOTE
If log sticks on wedge, load another piece of wood and
extend ram to push the stuck piece off the wedge.
NOTE
Do not hold auto control valve in return position. It
will damage the stop block or beam.
CAUTION
The cylinder stroke is designed so the wedge stops
approximately 1.5 in. (3.81 cm) from the end plate.
NOTE
3. Load a log onto the beam against the wedge.
4. Make sure all limbs are clear of crush zones.
5. Push and hold the control valve handle forward
(towards the wedge) to split the log. The wedge will
stop when the control valve handle is released, or
when the cylinder reaches the end of stroke.
6. Push the control valve handle backward and
release to return the wedge to its original position.
The control valve handle will return to the neutral
position when the wedge is fully retracted.
