14 DR ® 5-TON ELECTRIC LOG SPLITTER
Changing the Hydraulic Fluid
Tools and Supplies Needed
 6mm Allen Wrench

Clean Rags

Small Funnel

Hydraulic Fluid
 Approved Container (1 gallon or more capacity)
Replace the Hydraulic Fluid in the Electric Log Splitter after every 150 hours of
use. Take the following steps to replace the Fluid.
1. Make sure the Air Bleed Screw is screwed down tight.
2. Tip the machine up vertical on the Wheels (you may need to have someone
support the splitter to prevent tipping over). Clean the area around the
Hydraulic Fluid Fill/Drain Port (Figure 12) and then, using a 6mm Allen
Wrench, unscrew and remove the Dipstick located in the Hydraulic Fluid
Fill/Drain Port.
3. Tip the Splitter down onto the Legs as you drain the Fluid into an approved
Container (1 gallon or more capacity) and continue tipping the machine until
the Tank is empty (Figure 13).
4. Tip the Splitter up vertical onto the Wheels again and insert a Small Funnel
into the Dipstick opening.
5. Refill the Tank with 3.4 quarts of fresh Hydraulic Fluid.
6. Clean the Dipstick with a Rag, insert the Dipstick (do not screw the Dipstick
down when checking), remove and check the level; it should be between the
two marks on the Dipstick. If the fluid is too high, simply pour out a little at
a time into a suitable container by tilting the Electric Log Splitter. If the fluid
is too low, insert a small Funnel and add Hydraulic Fluid (See
“Specifications” in Chapter 2 for Fluid type) a little at a time, until the level
falls between the two marks on the Dipstick.
7. Clean the Dipstick and the Copper Washer thoroughly and reinstall the Dipstick, being careful not to damage the threads of
the aluminum Hydraulic Fluid Cylinder End Cover.
8. Lower the machine to the ground, loosen the Air Bleed Screw three or four turns counterclockwise and cycle the Ram back and
forth 3 or 4 times to purge any air from the hydraulic system (See Operating The DR 5-TON ELECTRIC LOG SPLITTER in
Chapter 3).
9. Periodically check fluid level to ensure it is between the 2 grooves around the dipstick. If the level is below the lower limit, fill
until level is correct.
Sharpening the Wedge
Tools needed:
 Fine-Toothed Flat File
1. Before each splitting session, check the sharpness of the Wedge. As required, remove any burrs or flat spots on the Wedge
using a fine-toothed flat file.
