About Your Log Splitter
Thank you for purchasing your Powerhorse log splitter!
About Your Log Splitter:
This log splitter is a machine designed to split wood logs using a hydraulically powered moving wedge.
The log splitter’s gasoline engine is used to pressurize the hydraulic system.
This log splitter is designed to split logs lengthwise with the grain only.
This log splitter model is capable of splitting logs up to 25” long and 14” in diameter.
Your splitter can be used in either a vertical or horizontal splitting position:
When the splitter is set up to operate in the horizontal splitting position, a log is placed on the
horizontal beam and the wedge moves horizontally into the end of the log to split it.
When the splitter is set up to operate in the vertical splitting position, the log is placed on the
end plate, upright on its end, and the wedge moves down into the top of the log to split it.
The horizontal splitting position is used for lighter logs that can be easily loaded onto the beam. The
vertical splitting position is used for heavier logs that are difficult to load onto the beam.
The technical specifications for your log splitter are provided in the Specifications section of this
manual.
WARNING
This log splitter uses a high-pressure hydraulic system to generate a very strong splitting
force.
Read the manual completely before using the machine to understand how to safely operate
and maintain it.
Follow all safety precautions presented throughout this manual. A summary of important safety
information can be found at the end of this manual.
Contact Powerhorse Product Support at 1-866-443-2576 for any questions about the appropriate
use of this log splitter and/or optional accessories.

Splitter
Components.
Closely inspect all log splitter components.
(See Machine Components section of this manual for diagram of components.)
If you have missing or damaged components, please contact Product Support at
1-866-443-2576.
Step Two:
Add Oil to Engine
Add oil to the engine. Using a funnel, add SAE 10W-30 oil up to the FULL mark
on the dipstick. (See engine Owner’s Manual for oil capacity and location of fill cap.)
Step Three:
Add Hydraulic Oil
to Reservoir and
Prime the Pump
WARNING: High fluid pressures and temperatures are developed in hydraulic log
splitters. Hydraulic fluid escaping through a pinhole sized opening can burn or puncture skin,
resulting in wounds that could cause blood poisoning, infection, disability, gangrene,
amputation, or death. Therefore, the following instructions should be heeded at all times when
inspecting or servicing the hydraulic components of the log splitter.
NEVER check for leaks with your hand. Leaks can be located by holding a piece of
cardboard or wood (at least two feet long) with your hand at one end and passing the
other end over the suspected area (wear eye protection). Look for discoloration of the
cardboard or wood.
NEVER adjust the pressure of the pump or valve.
If injured by escaping fluid, no matter how small the wound is, see a doctor at once. A
typical injection injury may be a small wound that does not look serious. However,
severe infection or reaction can result if proper medical treatment is not administered
immediately by a doctor who is familiar with injection injuries.
1. Remove hydraulic oil dipstick.
2. Refer to the Specifications section for approximate hydraulic oil capacity.
3. Fill reservoir with 10 wt. AW32, ASLE H-150, or ISO 32 oil. Use a funnel
4. Replace hydraulic oil dipstick and check that oil level reads full. Note: Do not
thread in dipstick when checking oil level.
5. Disconnect the spark plug wire from the spark plug
6. Pull on the starter grip recoil at least 20 times so that hydraulic fluid has cycled
through the pump
7. Reconnect the spark plug wire to the spark plug
8. Start engine and use control valve handle to extend and retract wedge 5 (five) times
to remove air from the high pressure lines.
9. With wedge retracted, check oil level again.

10. Replace hydraulic oil fill/vent cap.
11. Start engine and use control valve handle to extend and retract wedge five (5) times
to remove air from the high-pressure lines.
12. With wedge retracted, check oil level again. Fill if necessary.
WARNING: NEVER remove the hydraulic oil dipstick when the engine is
running or hot. Hot oil can escape causing severe burns. Allow log splitter to cool
completely before removing hydraulic oil dipstick.
Note: If the log splitter will be run for long periods of time in outdoor temperatures
above 70°F, we recommend changing the hydraulic oil to DEXRON III.
Step Four:
Lubricate Beam
Apply grease to beam. This will help prevent wear between the wedge and beam.
