Initial Setup
IMPORTANT!
Engine is shipped without oil. DO NOT start the engine before adding oil.
See Assembly Instructions section of this manual to assemble the log splitter before setup.
Step One:
Inspect Log 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
1-800-817-1005.
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
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.
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 near 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.
IMPORTANT
The hydraulic system oil filter for your log splitter is not factory installed. Make sure the
filter is installed before attempting to fill the hydraulic tank or start the engine.
(Installation instructions are provided in the “Assembly Instructions” section and are also
printed on the side of the filter).
1. Remove hydraulic oil cap.
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. Check that oil level is full. Oil level should be approximately one inch from the top
of the tank. Replace oil fill cap once oil level is full.

Initial Setup
Step Three:
Add Hydraulic Oil
to Reservoir
(continued)
5. Disconnect the spark plug wire from the spark plug. This prevents the engine from
starting until the hydraulic pump and cylinder are completely filled with oil. Make
sure the spark plug wire is held away from the spark plug with string or other
nonconductive material.
6. Push the valve control handle with one hand to the forward (extend) position
(towards the front of the cylinder). 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 ram five (5) times to
remove air from the high pressure lines.
9. With ram retracted, check oil level again. Fill if necessary.
10. Replace hydraulic oil fill/vent cap.
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.
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
Lubricate the surface of the beam with grease. This will help prevent wear between the ram
keepers and the beam.
Apply grease to the top of the beam and underneath the edge of the
beam, where the wear pads travel.
