•
NEVER operate your splitter near a flame or spark. Hydraulic oil and gasoline are flammable and can
explode.
• NEVER fill gas tank while the engine is hot or running. Allow the engine to cool before refueling.
• This unit 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 applicable local or state laws (if any). If a spark arrester is used it
should be maintained in effective working order by the operator.
-NOTE-
In the state of California, the above is required by law (Section 442 of the California Public Resources Code).
Other states may have similar laws. Federal laws apply on federal lands. A spark arrester muffler (optional by
manufacturer) is available at your nearest engine dealer. Check legal requirements in your area.
• ONLY use your hands to operate the control lever. NEVER use foot, knee, rope or any extension device.
• Split ONLY one log at a time. NEVER attempt to split two logs on top of each other.

ASSEMBLY
This log splitter has been partially assembled at the factory. Refer to the drawings and part lists should it become
necessary to disassemble the unit for repair or replacement of parts.
Inspect all components for damage. If you believe you have a damaged part please contact customer service
immediately at 1-800-222-8183.
WARNING: Exercise extreme caution, as parts are very heavy. Sufficient persons or mechanical handling
equipment should be used.
Refer to uncrating and assembly instructions for assembly procedures.
OPERATION
INTENDED USE: This log splitter is intended and designed to only split wood. NEVER use for any other
purposes. Doing so can cause injury or VOID THE WARRANTY.
IMPORTANT: This unit is shipped with oil but without gasoline in the engine. After assembly, see separate
Engine Manual for proper fuel and oil recommendations.
WARNING: DO NOT START OR RUN THE LOG SPLITTER WITHOUT OIL IN THE ENGINE AND
HYDRAULIC RESERVOIR.
FILLING THE HYDRAULIC RESERVOIR
Fill the hydraulic reservoir to the top mark on the dipstick with DexronIII / MerconIII automatic transmission
fluid, a 10W AW hydraulic fluid or Pro-MixAW-32 Hydraulic oil. After the hydraulic reservoir and the engine
crankcase are filled correctly with their respective oils, start the engine. Remember to set the throttle and turn on
the fuel shut-off valve. The hydraulic pump should prime itself. With the engine running, move the hydraulic
valve lever toward the wedge. This will cause the cylinder to extend and expel air. When the cylinder is fully
extended, retract it. Repeat this procedure several times. (An erratic movement of the cylinder and wedge indicates
that there is air in the system). Once the cylinder has a smooth and constant speed indicating that all air has been
expelled, shut the system off and refill the reservoir until the fluid is in the safe operating range as specified by the
marks on the dipstick.
START UP
WARNING: DO NOT START OR RUN THE LOG SPLITTER WITHOUT OIL IN THE ENGINE
AND HYDRAULIC RESERVOIR.
See separate Engine Manual for fuel and oil recommendations. If applicable your log splitter has come equipped
with a fuel shut-off valve for towing purposes.
Before starting engine make sure crankcase is filled correctly with oil and the proper fuel has been used. The
engine will only start when the throttle lever and fuel shut-off valve if applicable are turned to their ON positions.
STARTING INSTRUCTIONS
1. Move throttle control to “FAST.”
2. Set Choke to on position (if applicable) or push primer bulb three (3) times. NOTE: Do not use primer or
choke to restart a warm engine after a short shutdown.
3. Grasp rope handle and pull out slowly until resistance it felt. Then pull rapidly with a full arm stroke.
NOTE: If engine fails to start after three (3) pulls, repeat steps 1 and 2.
4. When Engine starts, set choke to off position (if applicable) leave throttle control at “FAST.” The throttle
must be set in the fast position for maximum performance.
5. To stop engine, move throttle lever to “SLOW” for a few seconds then to “STOP.”

7
COLD WEATHER START UP
The Cold Weather Clutch enables the engine to be started without having to pull through cold,
thickened hydraulic fluid. Simply pull the handle out into locked position. Start engine, let it warm up,
and release Cold Weather Clutch. After starting, assure that the lever has reengaged.
SPLITTER OPERATION
1. Set up the log splitter in a clear, level area and block the wheels. The suction port on the tank should
always be on the lower side of the log splitter.
2. Place a log on the beam, against the foot plate. Make sure the log is securely on the foot plate and up
against the beam.
3. Depress the valve lever so that the cylinder will drive the push block into the log. Extend the cylinder
until the log splits or to the end of its stroke. If the log has not completely split after the cylinder has
reached the end of its extension, retract the cylinder. NOTE: Leaving the valve in the “actuate” position
at the end of the stroke may damage the pump. Always use extra care when splitting logs with ends that
are not square.
NOTE: To extend the life of the hydraulic cylinder, avoid “BOTTOMING OUT” the cylinder.
TOWING SAFETY
This unit should not be towed on any street, highway, or public road without checking the existing federal, local,
and state laws. Any licensing or modifications such as taillights, etc., need to comply with existing federal, local,
or state vehicle requirements is the sole responsibility of the purchaser. Obey all regulations when towing on
public roads and highways. See also SAFETY PERCAUTIONS.
Turn the fuel shut-off valve if applicable OFF to prevent flooding of the engine while traveling.
Be careful when backing up. You can easily jack-knife your splitter.
TOWING AT NIGHT
The requirements for taillights are based on States regulations. Some states allow towing at night as
long as the towed equipment does not visibly impair the tow vehicle taillights. This is based on a state,
to state requirements. The customer is responsible for meeting the states requirements.
If a “Statement of Origin” is required in your state, see your local dealer to receive one.
HYDRAULIC SAFETY
The hydraulic system on your splitter requires careful inspection along with the mechanical parts. Be sure to
replace any frayed, kinked, cracked or otherwise damaged hydraulic components. Just because it isn’t leaking
today doesn’t mean that it will not fail tomorrow.
Fluid escaping from a very small hole can almost be invisible. Do not check for leaks with your hand. Escaping
fluid under pressure can have sufficient force to penetrate skin causing serious personal injury or even death.
Leaks can be detected by passing a piece of cardboard or wood over the suspected leak and looking for
discoloration.
IF injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop if
proper medical treatment is not administered immediately.
Should it become necessary to loosen or remove any hydraulic fittings, lines or reservoir cap, be sure to relieve all
pressure by shutting of the engine and moving the control handle back and forth several times.
NEVER remove the cap from the hydraulic tank or reservoir while the unit is running. Hot oil under pressure
could result in serious injury. See also SAFETY PERCAUTIONS.
The pressure relief valve on your splitter is preset at the factory. DO NOT adjust the valve. Only a qualified
technician should perform this adjustment.

MAINTENANCE AND STORAGE
WARNING: DISCONNECT THE SPARK PLUG BEFORE PERFORMING ANY MAINTENANCE.
Consult the operating and maintenance instructions of the engine manufacturer for engine care.
Always check the oil level of the hydraulic reservoir before operation. Operating without an adequate oil
supply will cause severe damage to the pump. Change the hydraulic fluid in the reservoir after every 100 hours of
operation. Change the hydraulic filter after every 50 hours of operation (use only a 10 micron hydraulic filter).
Periodically check that all nuts, bolts, screws, clamps and fittings are tight and secure.
To keep your splitter in top working condition perform all recommended maintenance procedures before you use
your splitter.
If the wedge becomes dull or nicked a grinder or sharpening tool can be used to sharpen it.
Completely drain the fuel tank prior to storage. Always store gasoline in an approved, tightly sealed container. Store
container in a dry, cool place with adequate ventilation. Keep fuel away from areas where fumes could contact open
flame, pilot light or sparks.
Be aware of the environment when disposing of used petroleum products. Please dispose of used hydraulic
fluid, engine oil and any by products from the maintenance of your splitter at approved recycling centers.
Should it become necessary to disassemble the unit for repair or replacement of parts, refer to the drawings and parts
list on the following pages. Exercise extreme caution, as some parts are very heavy and will require sufficient
persons or mechanical handling equipment.
Your Swisher Log Splitter has been produced with components designed specifically to this machine. Although
standard springs, hardware and ect may look similar to parts used on other machinery, they may in some cases
be made of a different construction and/or materials. All replacement parts must meet manufacturer’s
specifications.
The operation of any splitter can produce foreign objects to be thrown into the
eyes, resulting in severe eye damage. Always wear certified safety glasses or
wide-vision safety goggles over spectacles before staring any splitting machine
and while operating such a machine.
The operation of any splitter produces sound waves that are damaging to the
human ear. Ear protection is recommended.

SWISHER HISTORY
Back before electricity came to rural Missouri Max Swisher was producing lawn mowers
from his mother’s chicken house. Max never liked to mow grass. He installed a
gearbox on his family’s lawn mower creating a self-propelled unit. By tying one end of a
rope to the mower and the other end to a tree in the center of the yard the mower
circled the tree, shortening the rope and guiding the mower in concentric circles. Max
enjoyed relaxing under a shade tree while his invention did all the work.
Max had designed his first self-propelled rotary lawn mower to do his dirty work for him.
Neighbors noticed his new invention and began asking him to make more. Today, 60
years later, Swisher is still producing innovative lawn and garden and ATV/UTV
equipment designed to give us all more “relaxing in the shade” time.
Swisher products have been featured nationally on television programs such as Regis
and Kathie Lee and seen in publications like ATV Magazine, Country Journal, Popular
Mechanics Magazine and others. In January 2000 Popular Mechanics Magazine
named Max’s zero turning radius riding mower one of the 20th century’s top household
inventions.
Swisher offers value and function in its products to meet your grounds maintenance
needs. CELEBRATING OVER 65 YEARS OF INNOVATION
SINCE 1945
