Periodic Maintenance - North Star M11960U.1 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

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.
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.
