REPAIRS OR MAINTENANCE.
S YMPTOM P OSSIBLE C AUSE
Ram will not move
or is slow to
respond. ⇒ The Air Bleed Screw may not be open. See page 13, step 3.
⇒ The motor Reset has tripped; push the Reset Button (Figure 1 on page 10).
⇒ Bleed any accumulated air from the hydraulic system. See page 20, step 6.
⇒ The Wood Splitter may not be on a level surface. See page 13, step 1.
⇒ Make sure the voltage at the outlet or extension cord connection to the 4-TON
ELECTRIC/HYDRAULIC DR WOOD SPLITTER is 110-120VAC.
⇒ If you are using an extension cord, make sure that the cord is no more than 25 feet
long, is not smaller than 12 AWG wire or no more than 50 feet long, and is not
smaller than 10 AWG wire.
⇒ The hydraulic fluid may be low. Check and adjust the level as required. See page 20.
⇒ In extreme high temperature and heavy rapid use, the hydraulic fluid may have
overheated. Allow the machine to cool.
⇒ The wood you are splitting may be too hard, it has knots, or its fiber is very tough.
Log fails to split .
⇒ Check the possible causes for the previous Ram operation symptom.
⇒ Incorrect positioning of the log; re-position the log flat on the splitting beam with
the ends squarely against the Ram face and Splitting Wedge.
⇒ Log exceeds permitted dimensions or the wood is too hard for the capacity of the
machine. The maximum log length is 20" with a maximum diameter of 10" for the
4-TON ELECTRIC/HYDRAULIC DR WOOD SPLITTER.
⇒ The Splitting Wedge has burrs or nicks and needs sharpening. See page 20.
⇒ There may be a hydraulic fluid leak. Locate the leak using a piece of cardboard
under the machine. Visit our website at www.DRPower.com , call 1-800-DR-OWNER
