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, cause burns, fire or explosion,
or escaping high pressure hydraulic fluid.
Important Safety Instructions:
1.Engine Off. Always make sure the tractor engine is off before cleaning, repairing or adjusting the splitter, except as
recommended by the manufacturer.
2.Hydraulic Safety.
1.Please pour into at least 20L hydraulic fluid before using this machine for the first time.
2.We sincerely recommend you to choose ESSO "Nuto Hzz" or Royal Dutch Shell "Tellus Tzz" hydraulic fluid for
your machine.
3.Before starting the engine, please pull the rope of the engine several times to make sure the fuel system filled with
the hydraulic fluid, this may relieve the pressure for the hydraulic parts.
4.After using for the first time, place clean up the filter and make sure to do this cleaning for it regularly in order to
avoid blocking the filter.
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 can 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 off tractor engine, move all control valve handles back band forth to relieve pressure, and disconnect
hydraulic lines before changing or adjusting hydraulic system components such as hoses, tubing, fittings or other
components.
• 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 one. A typical injection injury may
be a small puncture wood 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
Slow cylinder shaft speed when extending or retracting
Wood will not split or splits extremely slowly
Tractor engine bogs down during splitting
Tractor engine stalls under low load condition
Cause
A-Insufficient oil to pump
B-Air in oil
C-Excessive pump inlet vacuum
D-Blocked hydraulic lines
E-Blocked control valve
F-Low control valve setting
G-High control valve setting
H-Damaged control valve
I-Internal control valve leak
J-Damaged cylinder piston
K-Internally damaged cylinder
