    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 engine 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. If your log splitter is equipped with an internal-combustion engine and intended for use near any unimproved forest, brush, or grass covered land, the engine exhaust should be equipped with a spark arrestor. Make sure you comply with local, state, and federal codes. Take appropriate fire-fighting equipment with you.

14. 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.

15. 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.

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

17. 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.

18. 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.

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

20. Do not refuel the engine until it has cooled for several minutes.

• Please read Alphaworks “Gasoline Engine Manual” for engine operation requirements and precautions.
  Add Hydraulic Oil
  DO NOT remove the hydraulic oil fill cap when the engine 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 engine (see Starting the Engine in the Operation section).
7. Extend and retract the cylinder to purge air from the hydraulic system. Cylinder motion should be smooth and continuous.
8. Shut-off engine (see Stopping the Engine in the Operation section).
9. Hydraulic oil can be added appropriately when the cylinder thrust is insufficient.

For safety reasons, hydraulic oil, oil and fuel are 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. Clean debris from the engine cylinder, cylinder head fins, recoil starter cover, and muffler areas. If the engine is equipped with a spark arrestor muffler, clean and inspect it regularly (follow manufacturer’s service instructions). Replace, if damaged.
3. Never store the unit indoors with fuel in the tank. Fumes might reach an open flame spark. Allow the engine to cool before storing in any enclosure.
4. Clear debris from movable parts, but only when the power source is shut off.
5. 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. Engine motor vibration may shake screws and bolts loose during operation.
