DR Power Hydraulic 4-Ton (January 2008 - Present) - Manual (Page 24)

20 WDS 4.4, 4-TON ELECTRIC/HYDRAULIC DR ® WOOD SPLITTER
Adjusting the Hydraulic Fluid Level
NOTE: Check the hydraulic fluid level every few months if the Troubleshooting Table (page 23) suggests that the
fluid level may be off.
•
BEFORE PERFORMING ANY MAINTENANCE, YOU MUST UNPLUG THE WOOD SPLITTER FROM THE
POWER SOURCE. MAKE SURE THE HYDRAULIC SYSTEM IS DEPRESSURIZED (SEE PAGE 7), AND MAKE
SURE THE FLUID HAS COOLED.
•
READ THE "GENERAL SAFETY RULES" (CHAPTER 2) OF THIS MANUAL BEFORE PERFORMING ANY
REPAIRS OR MAINTENANCE.
Tools Needed:
•
Adjustable Wrench
•
#3 Phillips Screwdriver
1. Depressurize the hydraulic system (see page 7).
2. Check the hydraulic fluid level by tipping the machine up vertical on the Wheels.
3. Clean the area around the Hydraulic Fluid Fill/Drain Port. It is important not to let any debris enter
the fluid reservoir (Figure 9 on page 14). Loosen the Air Bleed Screw and then, using an Adjustable
Wrench, unscrew the Dipstick located in the Hydraulic Fluid Fill/Drain Port.
4. Clean the Dipstick and replace without screwing down to 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 wood splitter. If the fluid is too low, add AW32 hydraulic fluid, (or Dexron
®
ATF, if used) a little at a time, until the level falls between the two marks on the Dipstick.
5. Clean the Dipstick and the O-ring seal thoroughly and reinstall, being careful not to damage the
threads of the aluminum Hydraulic Fluid Cylinder End Cover.
6. Cycle the Ram back and forth 3 or 4 times to purge any air from the hydraulic system (see step 3 on
page 13).
