SAFETY RULES

WARNING: The double-insulated system is intended to

protect the user from shock resulting from a break in the tool's

internal wiring. Observe all normal safety precautions related to

avoiding electric shock.

1. Know your machine. Read this manual carefully. Learn

the machine’s applications and limitations, as well as

specific hazards.

2. Ground all machines. This machine is Double Insulated,

meaning that all outside metal parts are insulated from

electrical power. Double Insulated tools are equipped with

a polarized plug. This plug will fit in a polarized outlet only

one way. If the plug does not fit fully in the outlet, reverse

the plug. If it still does not fit, contact a qualified

electrician to install a polarized outlet. Do not attempt to

circumvent this safety feature.

3. Do not expose the tool to moisture. Don’t use this

machinery in damp or wet locations and keep it out of the

rain.

4. Keep the work area clean. Cluttered areas invite injuries.

5. Keep children and pets away. All children should be kept

away from the work area. Never let a child handle a tool

without strict adult supervision.

6. Do not operate this tool if under the influence of alcohol

or drugs or if you are tired. Read warning labels on

prescriptions to determine if your judgment or reflexes are

impaired while taking the medication. If there is any doubt,

do not attempt to operate.

7. Use safety equipment. Eye protection should be worn at

all times when operating this machine. Use ANSI

approved safety glasses. Everyday eyeglasses only have

impact resistance lenses. They are NOT safety glasses.

A dust mask, respirator, non-skid safety shoes, a hard hat,

or hearing protection must be used in appropriate

conditions.

8. Wear the proper apparel. Loose clothing, gloves, neckties,

rings, bracelets, or other jewelry may present a potential

hazard when operating this machine. Please keep all

apparel clear of the machine.

9. Don’t overreach. Keep proper footing and balance at all

times when operating this product.

10. Always disconnect the machine from the power source

before servicing or changing the accessories.

11. Check for damage. Check your tool regularly. If any part

of the tool is damaged it should be carefully inspected to

make sure it can perform its intended function correctly. If

in doubt, the part should be repaired. Refer all service to

a qualified technician. Consult your dealer for advice.

12. Keep away from flammables. Do not attempt to operate

this tool near flammables or combustibles. Failure to

comply may cause serious injury or death.

13. Do not start the log splitter while a log is on the work table.

Always turn the splitter on BEFORE placing a log to be

split on the work table.

14. Always check to make sure that the switch is not

engaged before plugging in power cord.

15. Keep your hands clear of the cutting edges and all

moving parts. Do not place hands between log and

splitting wedge, or between the log and push rod during

operation.

16. Protect others in the work area from debris such as chips

and sparks. Provide barriers and shields as needed.

17. Use the right tool for the job. Do not use a tool or

attachment to do a job for which it was not intended. Do

not alter a tool.

18. Use only authentic accessories. Using noncompliant

accessories may be hazardous. Be sure that all

accessories are properly installed and maintained.

19. Remove all adjusting keys and wrenches. Make a habit of

checking that the adjusting keys and wrenches are

removed from the tool before turning it on.

20. Guard against electric shock. Prevent body contact with

grounded surfaces such as pipes, radiators, ranges, and

refrigerators. Hold your tool by the insulated, non-metal

grasping surfaces. Use a Ground Fault Circuit Interrupter

(GFCI) to reduce shock hazards.

21. Avoid accidental starting. Be sure your tool is turned off

before plugging it in. Do not use a tool if the power switch

does not turn the tool on and off. Do not carry a plugged-

in tool with your finger on the switch.

22. Do not force the tool. Your tool will perform better when

used appropriately. Excessive force only causes operator

fatigue, increased wear and reduced control.

23. Do not abuse the cord. Never carry your tool by its cord

or unplug it by pulling the cord from the outlet. Pull the

plug rather than the cord to reduce the risk of damage.

Keep the cord away from heat, oil, sharp objects, cutting

edges and moving parts.

24. Treat your tools with care. Keep handles dry, clean and

free from oil and grease. Follow the instructions for

lubricating and changing accessories. Periodically inspect

tool cords and extension cords for damage. Refer all

service to a qualified technician.

25. Store idle tools. When not in use, store your tools in a dry,

secure place. Keep out of reach of children.

26. If an extension cord is needed, it must be 121 AWG and

3-wire type.

27. Split only one log at a time.

28. Make sure the log is free of nails or other foreign objects.

29. Never use the log splitter for any other purpose other

than splitting wood.

30. Never attempt to load a log while the push rod is in

motion.

31. When loading a log, place hands on the sides of the log,

not on the ends.

32. Wait for the push rod to stop moving before loading

another log onto the splitter.

33. High pressure and temperatures can be produced in this

log splitter. Never place your hand(s) near a hydraulic

leak, or use your hands to check for leaks. Use a piece of

cardboard or stiff paper to check of leaks in the hydraulic

lines.

WARNING: Do not use the Log Splitter in wet or damp

areas or expose it to rain.

WARNING: Do not use it in areas where fumes from paint,

solvents or flammable liquids pose a potential hazard.

INSPECT YOUR LOG SPLITTER

Check your Log Splitter before turning it on. Keep Guards in

place and in working order. Make a habit out of checking to see

that keys and adjusting wrenches are removed from tool area

before turning it on. Replace damaged, missing or failed parts

before using it.

INSPECT THE LOGS

Make sure there are no nails or foreign objects in the logs to be

split. The ends of the logs must be cut square. Branches must be

cut off so that they are flush with the trunk.

DON’T OVERREACH

Never stand on the Log Splitter. Serious injury could occur if the

tool is tipped or if the wedge is unintentionally contacted. Do not

store anything above or near the Log Splitter where someone

might stand on the tool.

AVOID INJURY FROM UNEXPECTED ACCIDENTS

Always pay full attention to the movement of the Log Push Rod.

CAUTION: Do not attempt to load the log on until the Log

Push Rod has stopped.

CAUTION: Keep your hands out of the way of all moving

parts.

PROTECT YOUR HANDS

Keep you hands away from splits and cracks which open in the

log. They may close suddenly and cause serious bodily injury.

CAUTION: Do not remove jammed logs with you hands.

Don’t leave the Log Splitter until it has come to a complete stop,

is turned off and unplugged.

MAINTAIN YOUR LOG SPLITTER WITH CARE

Keep the Log Splitter clean for safe and efficient performance.

APPLICATION CONDITIONS

This Log Splitter is designed for home use. It is built to operate

best at temperatures between 41ºF and 104ºF. The surrounding

humidity should less than 50% at 104ºF. It should be stored or

transported at temperatures between -13ºF and 131ºF.

NOTE:A small log can be difficult to split when it has knobs

or a particularly tough fiber. On the other hand, it may not be

difficult to split logs with regular fibers even if its diameter

exceeds the maximum diameter specifications.

Screw

•Before operating the Log Splitter, the Bleed Screw should be

loosened until air goes in and out of the Oil Tank smoothly.

•Airflow through the Bleed Screw Hole should be detectable

during operations.

•Before moving the Log Splitter, make sure the Bleed Screw is

tightened to avoid Oil leaks.

WARNING: Failure to loosen the Bleed Screw will keep the

air in the Hydraulic System compressed after being

decompressed. Continuous compression and decompression will

blow out seals on the Hydraulic System and cause permanent

damage to the Log Splitter.

WARNING: DO NOT ADJUST THE MAX PRESSURE

LIMITING SCREW! The Max Pressure Limiting Screw is sealed

with glue to ensure that the Log Splitter works under no more

than 5 tons of pressure. The setting was done by qualified

mechanics with professional instruments. Unauthorized resetting

will cause the Hydraulic Pump to fail to output enough splitting

pressure and could RESULT IN SERIOUS INJURY AS WELL AS

DAMAGE TO THE MACHINE.

WIRING DIAGRAM PLUMBING DIAGRAM

OPERATION

1. This Log Splitter is equipped with a ZHB Control System

that requires it to be operated with both hands (the left

hand controls the Hydraulic Control Lever while right

hand controls the Pushbutton Switch). The Log Splitter

will freeze when either hand is absent. Only after both

hands release the controls, will the Log Pusher return to

the starting position.

WARNING: Never force the Log Splitter for more than 5

seconds.

2. After a 5-second interval, the Oil under pressure will

overheat and the machine could be damaged. For an

extremely hard log, rotate the log by 90º to see whether it

can be split in a different direction. If you are not able to

split the log, its hardness exceeds the capacity of the

machine and thus that log should be discarded to protect

the Log Splitter from damage.

3. Always set the log firmly on the Retaining Plates and

Work Table. Make sure the ends of the log are square, so

the log does not twist, rock or slip while being split. Do

not force the blade by splitting the log using only the

upper part of the blade. This could break the blade or

damage the machine.

WARNING: Break the log in the direction of its growing

grain. Do not place the log across the Log Splitter. This is

dangerous and may seriously damage the machine.

WARNING: Do not attempt to split two logs at the same

time. One of them may fly up and hit you.
