universal tractor/transmission fluid.
NOTE
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.
WARNING

13 REV 93520-20130425
ENGLISH 93520
Add Fuel Cont’d.
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.
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.
Pouring fuel too fast through the fuel screen may
result in blow back of fuel at the operator while

WARNING
6. Screw on the fuel cap and wipe away any spilled
fuel.
ASSEMBLY
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
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 tank at the gas
station. Use an approved container to transfer the
fuel to the tank.
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.

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.
Towing Log Splitter Safety
1. Always check local and state regulations regarding the
requirements for towing, licensing and lights.
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. Towing
the log splitter at speeds greater than 45 mph 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.
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 KPH)

OPERATION
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 while under the influence of alcohol, drugs,
or medication.
NEVER leave the log splitter unattended while the
engine is running.
DO NOT change the splitting position with the engine
running. Contact with the muffler can cause serious
burns.
Always make sure the beam is in the locked position.
DO NOT let the beam drop as it could crush fingers
or cause damage to the log splitter.
WARNING
Log Splitter Location Cont’d. 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.

OPERATION
Log Splitter Operation
1. ALWAYS wear ear and eye protection, protective clothing
and safety gear.
Log Splitter Operation Cont’d.
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.
NOTE
It is normal for the hydraulic fluid to become foamy
or frothy during operation.
NOTE
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.
NOTE
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.
4. Load a log onto the beam against the end plate
(MAX LOG LENGTH – 24” [61 cm]).
5. Make sure all limbs are clear of crush zones.
6. Push the control valve handle forward (towards the
end plate) to split the log.
7. Push the auto control valve handle backward to
return the wedge to its original position.
8. Clear the split wood from the work zone.
Do not hold auto control valve in return position. It
will damage the stop block or beam.
CAUTION

OPERATION
Operation at High Altitude
The density of air at high altitude is lower than at sea
level. Engine power is reduced as the air mass and
air-fuel ratio decrease. Engine power and output will
be reduced approximately 3½% for every 1000 feet of
elevation above sea level. This is a natural trend and
cannot be changed by adjusting the engine. At high
altitudes increased exhaust emissions can also result
due to the increased enrichment of the air fuel ratio.
Other high altitude issues can include hard starting,
increased fuel consumption and spark plug fouling.
To alleviate high altitude issues other than the natural
power loss, Champion Power Equipment can provide a
high altitude carburetor main jet. The alternative main
jet and installation instructions can be obtained by
contacting Customer Support. Installation instructions
are also available in the Technical Bulletin area of the
Champion Power Equipment internet site.
The part number and recommended minimum altitude
for the application of the high altitude carburetor main
jet is listed in the table below.
In order to select the correct high altitude main jet
it is necessary to identify the carburetor model. For
this purpose, a code is stamped on the side of the
carburetor. Select the correct main jet part number
corresponding to the carburetor code found on your
particular carburetor.
Operation using the alternative main jet at
elevations lower than the recommended minimum
altitude can damage the engine. For operation at
lower elevations, the standard main jet must be
used. Operating the engine with the wrong engine
configuration at a given altitude may increase
its emissions and decrease fuel efficiency and
performance.
