 The Electric Log Splitter may not be on a level surface.
 Make sure the voltage at the outlet or extension cord connection to the DR 5-TON ELECTRIC
LOG 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.
 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 20.5" with a maximum diameter of 10" for the DR 5-TON
