Periodic Maintenance - Powerhorse M1156N Owner's Manual

In addition to the maintenance performed with each use, periodic maintenance should also be performed according
to the following schedule.
ALWAYS shut off the engine, disconnect the spark plug, and relieve system pressure before
cleaning, adjusting, or repairing the splitter. Relieve system pressure by moving Split
Control Lever back and forth several times.
IMPORTANT:
If a part needs replacement, only use parts that meet the manufacturer's specifications. Replacement parts that do
not meet specifications may result in a safety hazard or poor operation of the log splitter

Periodic Maintenance

Perform engine maintenance as specified in the engine owner's manual.
Change hydraulic oil annually / 100 hours.
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:
o 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.
o NEVER adjust the pressure setting of the pump or valve.
o 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.
1. Use 10 wt AW32, ASLE H-150, or ISO32 oil.
2. Relieve hydraulic system pressure by moving the split control lever back and forth
several times.
3. Remove hydraulic oil fill 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.
4.
Remove the suction hose from the hydraulic tank to drain the hydraulic oil.
5. Fill with the specified quantity
6. Replace dipstick and check that oil level reads full (before starting engine and checking
oil level again). Note: Do not thread in the oil dipstick when checking the hydraulic
oil level.
7. Dispose of used oil at an oil-recycling center. Used hydraulic oil is hazardous waste.
If the engine is equipped with a spark arrestor muffler, clean and inspect it regularly
(follow manufacturer's service instruction). Replace if damaged.
