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.
