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 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 split control lever back and forth to relieve pressure

before changing or adjusting hydraulic system components such as hoses, tubing, fitting or other

components.

● Do not remove the hydraulic oil fill cap when the engine is running. Hot oil can escape causing severe

burns. Allow log splitter to cool completely before removing hydraulic oil fill cap.

● Do not adjust the pressure setting of the pump or valve.

● 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.

● 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.
