DR  20-Ton WOOD SPLITTER Safety & Operating Instructions 7
Hydraulic Safety
Inspect hydraulic hoses every day – check for worn, frayed, kinked, and cracked areas.
Replace any damaged or worn hoses.
Periodically check for hydraulic leaks by placing a sheet of cardboard under the splitter
while the system is running.
Please follow these steps to depressurize system and release residual hydraulic energy
before starting any repairs.
1. Shut off splitter motor and disconnect the spark plug wire.
2. Move control valve handle back and forth, from one limit of travel to the other, at
least four times and holding the valve for three seconds at each limit of travel. The
ram should not move during the 4th cycle.
3. Call 1(800) DR-OWNER (376-9637), or a qualified hydraulic mechanic, to replace
worn components or for assistance.
Do not make any adjustments to the pressure relief valve.
Never remove cap from the hydraulic tank while motor is running or while tank is still
warm after motor is shut off. Hot pressurized fluid can cause serious injury, so wait for
hydraulic tank to cool before removing cap.
WARNING! The items listed in this section will help you keep your DR
20-Ton WOOD SPLITTER running smoothly and, most importantly, prevent
injury to yourself or others. Please review them carefully before starting your
machine.
WARNING! Escaping pressurized fluid from hydraulic system leaks can
have enough force to penetrate skin and cause serious injury or death.
Hydraulic fluid can remain highly pressurized while the splitter motor is off.
- Never use your hand or any part of your body to check for hydraulic system
leaks while the system is pressurized.
- Get professional medical help at once if hydraulic oil penetrates anyone's skin.
- Always release residual energy from pressurized hydraulic fluid and allow the
fluid to cool before doing any maintenance or repair work on the log splitter.
Important! Use only DR replacement connectors, valves, or fittings on your
machine. They have been thoroughly tested and proven for many hours of use.
