WARNING
READ and UNDERSTAND this manual completely before using log splitter.
All operators of this equipment must read and completely understand all safety information, operating instructions,
maintenance and storage instructions. Failure to properly operate and maintain the log splitter could result in serious
injury to the operator or bystanders from moving parts that can crush or cut, flying objects, burns, fire or explosion,
escaping high pressure hydraulic fluid, or carbon monoxide poisoning. In particular, be aware of the following
hazards: Crush and Cut Hazards
Moving parts can crush and cut hands and fingers. Keep hands clear of endplate, wedge, log strippers, and logs
while splitting. High Pressure Hydraulic Fluid Hazards
High fluid pressures and temperatures are developed in hydraulic log splitters. Hydraulic fluid escaping through
even a pin-size hole opening 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.
Fire Hazards
If your log splitter is intended for use near any ignitable forest, brush, or grassy covered land, the engine
exhaust should be equipped with a spark arrestor.

Thank you for purchasing your Dosko log splitter!
About Your Log Splitter
This log splitter is a machine designed to split wood logs using a hydraulically powered moving wedge.
The gasoline-powered engine is used to pressurize the system.
This log splitter model is capable of splitting logs up to 24″long and 16″in diameter
This log splitter is designed to split logs lengthwise with the grain only.
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 endplate, 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 the manual.
Contact Dosko Customer Service at 1-800-822-0295 for any questions about the appropriate use of
this log splitter or about optional accessories.
Attention: All Rental Companies and Private Owners who
loan this equipment to others!
All persons to whom you rent/loan the log splitter must have access to and read this manual. Keep this
owner’s manual in the splitter’s attached manual tube at all times and advise all persons who will operate
the machine to read it. You must also provide personal instruction on how to safely operate the splitter
and be available to answer any questions a renter/borrower might have.

WARNING
Carefully read and follow all instructions for initial assembly and set-up of
this log splitter.
Failure to properly assemble and set up this equipment could result in serious
injury to the user or bystanders, or cause equipment damage.
Step One:
Assemble Log
Splitter
Assemble your log splitter.
Closely inspect all log splitter components.
If you have missing components, contact Dosko Customer Service 1-800-
822-0295.
If you have damaged components, contact the Freight Company that
delivered the unit and file a claim.
See the “Assembly” section of this manual – It will provide you with detailed instructions
on:
Inspecting shipped components and whom to contact if anything is missing or
damaged.
Assembly.
Testing.
Step Two:
Add Oil to Engine
Add oil to 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
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. Start engine and use split control lever to extend and retract wedge 5 (five) times
to remove air from the high pressure lines.
6. With wedge retracted, check oil level again. Fill if necessary.
Note: If the log splitter will be run for long periods of time in outdoor temperatures above
70F, we recommend changing the hydraulic oil to DEXTRON III.

Step Four:
Check Hydraulic
System
Check the hydraulic system carefully:
1. Visually inspect all hoses, tubing, clamps/fittings, pump, and cylinder for cracks,
fraying, kinks, or other damage.
2. Check all components for oily residue, which may indicate a leak.
Do NOT operate the log splitter if there is any indication of damage or oily residue.
Small leaks in hydraulic lines can cause severe injuries and can also be an indication of
catastrophic failure in the near future. The life of hydraulic hoses may be from a few
months to a few years, depending on use and storage patterns.
WARNING: High fluid pressures and temperatures are developed in hydraulic
log splitters. Hydraulic fluid escaping through a pin hole 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:
Stop the engine, disconnect the spark plug, and move the split control lever
back and forth to relieve pressure before changing or adjusting hydraulic
system components such as hoses, tubing, fittings or other components.
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 setting 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 puncture 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.
WARNING: NEVER remove the hydraulic oil fill cap when the engine is
running or hot. Hot oil can escape causing severe burns. Allow log splitter to
cool completely before removing hydraulic oil fill cap.
