Troubleshooting

WARNING
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.
Problem
Cylinder rod will not move Solution: A,D,E,H,J
Slow cylinder shaft speed when extending or retracting Solution: A,B,C,H,I,K,L
Wood will not split or splits extremely slowly Solution: A,B,C,F,I,K
Engine bogs down during splitting Solution: G
Engine stalls under low load condition Solution: D,E
Cause Solution
A - Insufficient oil to pump Check oil level in reservoir
B - Air in oil Check oil level in reservoir
C - Excessive pump inlet vacuum Check pump inlet hose for blockage or kinks
D - Blocked hydraulic lines Flush and clean the splitter hydraulic system
E - Blocked control valve Flush and clean the splitter hydraulic system
F - Low control valve setting Adjust control valve with a pressure gauge
G - High control valve setting Adjust control valve with a pressure gauge
H - Damaged control valve Return control valve for authorized repair
I - Internal control valve leak Return control valve for authorized repair
J - Damaged cylinder piston Return cylinder for authorized repair
K - Internally damaged cylinder Return cylinder for authorized repair
L – Drawing air through suction line Check and tighten hose clamps on suction hose
