1" wrench (fitting)
7/8" wrench (hose)
Rando 46 (Texaco) hydraulic fluid
(approx. 1 qt. to refill)
Screwdriver
1. With the engine stopped, release any
residual hydraulic pressure by
moving the control lever back and
forth a couple of times.
2. Use the 7/8" wrench to hold the
high pressure hose end being
replaced while loosening the fitting
with the 1" wrench. (Figure 25)
3. Install the new hose in the reverse order.
4. To replace a low pressure hose, loosen the hose clamp with a screwdriver and slip the
hose off the connector nipple.
5. Install the new hose in the reverse order.
WARNING! Before performing any maintenance procedure, stop the
engine and disconnect the spark plug wire.
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 Rando 46 (Texaco) hydraulic fluid and DR replacement
hoses, connectors, valves, or fittings on your machine. They have been
thoroughly tested and proven for many hours of use.
