Operation Manual TIMBERWOLF Log Splitters
Caution!
Residual Hydraulic Energy
Residual energy must be released from the pressurized hydraulic fluid
before any maintenance or repair work is done on the log splitter.
Hydraulic fluid can remain highly pressurized even while the splitter's
motor is off. Escaping pressurized hydraulic fluid can penetrate skin and
cause serious injury.
To release residual hydraulic energy:
1. Shut off splitter motor (tractor motor if splitter is a three-point
hitch model).
2. Move control valve back and forth, from one limit of travel to the
other, at least four times.
3. Hold valve for three seconds at each limit of travel.

&WARNINGS
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 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 before doing any
maintenance or repair work on the log splitter.

frayed, kinked, and cracked areas.
I
• Replace any damaged or worn hoses.
• Use sheet of cardboard or log to check for hydraulic
leaks while system is running. -
• Depressurize system to release residual hydraulic
energy before starting any repairs.
1. Shut off splitter motor.
2. Move control valve handle back and forth, from one
limit of travel to the other, at least four times.
