Before troubleshooting or attempting to service, read the following safety instructions to avoid serious injury
to the operator or bystanders from moving parts that can crush or cut, burns, fire or explosion, or escaping
high pressure hydraulic fluid.
Important Safety Instructions:
1. Motor off. Always make sure the motor is off and battery is disconnected before cleaning, repairing, or
adjusting the splitter, except as recommended by the manufacturer.
2. Hydraulic safety. High fluid pressures and temperatures are developed in the 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:
• Turn motor off, move all control valve handles back and forth to relieve pressure, and disconnect battery before
changing or adjusting hydraulic components such as hoses, tubing, fittings, or other components.
• Do not remove the hydraulic oil fill cap when the motor is on. Hot oil can escape causing severe burns. Allow the log
splitter to cool completely before removing the hydraulic oil fill cap.
• Do not adjust the pressure setting to the pump or valve.
• Do not check for leaks with your hands. Leaks can be located by holding a piece of cardboard or wood (at least 2 feet
long) with your hand at one end and passing the other end suspected area (wear eye protection). Look for
discoloration of the cardboard or wood.
• 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 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 will injection injuries.
