Troubleshooting - Wel-Bilt M141300A Owner's Manual

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. Engine off. Always make sure the engine is off 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:
 Stop the engine, disconnect the spark plug, and move all control valve handles back and forth to relieve
pressure before changing or adjusting hydraulic components such as hoses, tubing, fittings, or other
components.
 Do not remove the hydraulic oil fill cap when the engine is running. 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 disassemble the spring tubes. The internal springs are powerful and can cause bodily harm if ejected.
 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.
