Warning! Before performing any maintenance, be sure that:
• Log splitter is disconnected from the power source
• Pusher plate is fully retractable (returned to the lowest position) and no residual hydraulic
energy is left in the system.
• Your machine is clean. Do not contaminate hydraulic fluid. Contaminants of hydraulic fluid
include solid particles, air, water or ay other matter that impairs the function of the fluid.
Contamination accelerates wear of hydraulic components.
• Oil has cooled

Changing Hydraulic Oil

Oil should be changed after every 200 hours of operation.
The drain screw is located under the unit.
Recommended Oil Types:
Shell Tellus T22
Aral Vitam GF22
SP Energol HCP22
Mobil DTE 11 or equivalent
IMPORTANT: Do not mix fluid brands and types. Do not use other grade.

To drain the oil, tip unit back on support bracket, place an empty container that can hold at
least 1 Gallon (4 Liters) of oil under the log splitter.
Use an Allen Wrench and remove Drain Port Plug and O-ring in the aluminum bottom cover
plate of the log splitter.
Hold the handle, move unit up a little and position it under the angle. Using an Allen
Wrench, unscrew the dipstick and open the Oil Fill Port to let air in and help the oil flow out.
Wait until the oil completely escapes from the oil reservoir.
Reinstall the Drain Port Plug and the O-ring seal. Be careful not to damage the threads of
the Aluminum Bottom Cover.
After the used oil is drained, pour approximately 0.7 Gallon (2.6 Liters) of recommended oil
into the Oil Fill Port.

Clean the Dipstick and insert it to check the oil level; it should be between the two notches

on the stem. If level is low, add recommended type of the hydraulic oil. If the level is too
high, poor out a little at a time into a container.
IMPORTANT! If the oil level is too high, the heat will not be dissipating quickly enough and the
temperature of the hydraulic system will rise. If the oil level is too low, it may cause cavitation.*
*Cavitation occurs when the volume of hydraulic fluid demanded by any part of a hydraulic circuit
exceeds the volume of fluid being supplied. If there is an air bubble in the system, the force applied
gets used compressing the air in the bubble rather than moving the piston. This affects the
efficiency of the system. In this case, Force (Rated 6 tons) will be cut down.
Reinstall the Dipstick and the O-ring. Be careful not to damage the threads of the Dipstick
Plug and Aluminum Top Cover.
Clean thoroughly.
Loosen air bleed screw, turn 3-4 times.
Purge air from the hydraulic system by cycling the pressure plate back and forth 3 to 4
times.
Warning! Dumping used hydraulic oil in the environment is forbidden and illegal. The fluid
must be disposed of in accordance with local environmental rules and procedures.
