SAFETY GUIDELINES

Cancer and Reproductive Harm – www.P65Warnings.ca.gov

Moving parts can entangle hands, feet, hair, clothing and/or accessories. Traumatic amputation or severe laceration can result. Keep hands and feet clear moving parts. Tie up long hair and remove jewelry before operating the device. Operate equipment only fully assembled and with guards in place. DO NOT wear loose-fitting clothing, dangling drawstrings or items that could become caught.

Operation of this equipment may create sparks that can start fires around dry vegetation. Spark arrestor may be required. The operator should contact local fire agencies for laws or regulations relating to fire prevention requirements.

Crush Hazard Wedge can cut through skin and break bones and in extreme cases amputate limbs and digits. Keep all limbs away from wedge and endplate at all times.

Skin Injection Hazard. High pressure hydraulic oil can break skin and cause sever injury. Make sure all fittings are seated firmly and tightly secured before applying pressure. Relieve system of pressure before servicing.

Parts of the hydraulic circuit (cylinder, pump, valve-body, hoses) can become very hot during operation.

This product IS NOT intended to to be towed behind a vehicle of any sort. The handle and wheels of the product are intended for the sole purpose of easily moving the log splitter on your work site. Any modification or changes to allow moving of this product by any other means other than by hand will render all warranties null and void.

Improper treatment or use of the log splitter can damage it, shorten its life and void your warranty. Use the log splitter only for intended uses.

Operate only on level surfaces.
DO NOT expose log splitter to excessive moisture, dust, or dirt. Cover with a tarp or store in a shed when not in use.
DO NOT allow any material to block the cooling vents.
DO NOT use product if you observe electromotor if:
– Equipment sparks, smokes or flames from the motor
– Equipment vibrates excessively.
– Hydraulic Fluid is leaking from the unit

ELECTRICAL SAFETY

Power tool plugs must match the outlet. Never modify the plug in any way. DO NOT use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

DO NOT expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

DO NOT abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

OPERATION

1. Read the Operator’s Manual completely before attempting to use this log splitter.

2. Do not allow anyone to operate your log splitter who has not read the Operator’s Manual or has not been instructed on the safe use of the log splitter.

3. Never allow children or untrained adults to operate this machine.

4. Never leave the machine unattended with the electromotor running.

5. Never operate the machine when under the influence of alcohol, drugs or medication

6. Many accidents occur when more than one (1) person operates the log splitter. If a helper is assisting in loading logs to be split, never actuate controls until helper is clear of the area.

7. Never allow anyone to ride on the machine during use or during operation.

8. Never transport cargo on the log splitter.

9. Always operate the log splitter with all safety equipment in place and all controls properly adjusted for safe operation.

10. High fluid pressures are contained in hydraulic log splitters. Pressurized hydraulic fluid escaping through a pin hole opening can puncture skin and cause sever bleeding and result in blood poisoning. Therefore, the following instructions should be heeded at all times.
    – Be sure to confirm all hose connections and hose clamps are tight before each use. It is possible for connections to vibrate loose over time
    – Do not operate the unit with frayed, kinked, cracked or damaged hoses, fittings, or tubing.
    – Stop the electromotor and relieve hydraulic system pressure before changing or adjusting fittings, hoses, tubing, or other system components.
    – Do not adjust the pressure settings of the pump or valve. The factory presets are tested for optimal system performance. Tampering with or modifying these settings will render your product warranty nu,, and void.
    – Do not check for leaks with your hand. Leaks can be detected by passing cardboard or wood over the suspected area. Look for discoloration. If injured by escaping fluid, see a doctor at once. Serious infection or allergic reaction can develop if proper medical treatment is not administered immediately.

11. Keep the operation zone and adjacent area clear for safe, secure footing.

12.  Always keep hands and feet clear of moving parts.

13. Log splitters should be used only for splitting wood. Do not use for other purposes unless the manufacturer provides attachments and instructions for such purposes.

14. When loading a ram-type log splitter, place your hands on the sides of the log, not the ends. Never place your hands or any part of your body between a log and any part of the log splitter

15. Only split wood WITH the grain. NEVER split perpendicular to the grain.

16. On ram-type log splitters, never attempt to split more than one log at a time unless the ram has been fully retracted and a second log is needed to complete the splitting of the first log.

17. On ram-type log splitters when the logs are not squared, the longest portion of the log should be rotated down and the most squared end placed against the ram.

18. Use only your hand to operate the log splitter controls, never kick the handle with your feet.

Add Hydraulic Oil

DO NOT remove the hydraulic oil fill cap when the electromotor is running or hot. Hot oil can escape causing severe burns.
Always allow the log splitter to cool completely before removing the hydraulic oil cap.
High fluid pressure and temperatures are created in the hydraulic log splitters. Hydraulic fluid will escape through a pin-size
hole opening and can puncture skin.
Inspect hydraulic system regularly for possible leaks.
Never check for leaks with your hand while the system is pressurized. Seek medical attention immediately if injured by escaping fluid.

To check hydraulic oil level, insert the dipstick into fill neck until it stops. Remove and read level. Do not thread dipstick into fill neck when checking oil.
When the outdoor temperature is below 32°F , Dexron III transmission fluid can be used.

1. Make sure the log splitter is on a flat, level surface.
2. Remove the dipstick from the oil tank.
3. Add 1.6gallon of hydraulic oil – AW32 / AW46
4. Check hydraulic oil level with oil dipstick. The oil level should be on the dipstick.
5. Tighten the dipstick.
6. Start electromotor.
7. Extend and retract the cylinder to purge air from the hydraulic system. Cylinder motion should be smooth and continuous.
8. Shut-off electromotor.
9. Hydraulic oil can be added appropriately when the cylinder thrust is insufficient.

For safety reasons, hydraulic oil is not included in the package.

MAINTENANCE AND STORAGE

1. Always shut off the power source while repairing or adjusting the splitter except as recommended by the manufacturer.
2. Clear debris from movable parts, but only when the power source is shut off.
3. Check to be sure all nuts and bolts are tight to assure the equipment is in safe working condition prior to each usage, and periodically during usage. Electromotor vibration may shake screws and bolts loose during operation.
