3.  The machine can be stopped at any time by pushing the 

STOP

 push button; otherwise, it 

will stop at the time intervals selected on the timer located on the machine's control panel. 
 The required cycle time will vary with the application. 

 
4.  The normal spin time for most sludges is 30-45 minutes depending upon the density and 

liquid type. The more viscous the liquid or smaller the fine, the longer it will take to extract the 
fluid.  

 
5.  When the green 

OPEN

 signal illuminates the cycle is complete. 

 
6.  Open the lid. Release the pan cover by removing the spindle nut . 
 
7.  Reconnect the hoist hook and raise the pan cover and pan from the machine. 
 
8.  Dump the dry sludge either using the machine’s trunnion dump mechanism or   
 

whatever technique the customer has devised. 

 
 

EMERGENCY OPERATION 

If you hear strange noises coming from the machine while it is running 

DO NOT TRY TO OPEN 

THE MACHINE’S LID !!!!

  This could lead to severe injury. 

 
Either push the STOP button on the operating station or throw the disconnect on the machine’s 
control panel to the OFF position.  If the power is disconnected the machine will coast to a stop 
(which could take up to 15 minutes). 
 
 

OUT OF BALANCE SWITCH

 (OPTIONAL ON SOME MODELS) 

All model # 1100 and some # 400 machines are equipped with an out-of-balance switch.  
These switches are located on the underside of the drum's floor.  In the event of any severe 
vibration the switch is activated.  Immediately, the cycle in progress is terminated, and the 
machine is braked to a complete stop.  A flashing red light on the pushbutton station will 
indicate that the cycle was terminated due to an out of balance condition.  Pushing the 

Stop

 

push button will reset the switch.  The load should be checked for an out-of-balance condition 
and corrected; then the load can be processed as usual within the machine. 
 
 

45-GALLON CAPTURE TANK

 (OPTIONAL) 

Set Up 
Remove the three-inch pipe nipple from the 90° elbow located at the rear of the Oil Extractor 
(chip wringer). Slide the capture tank toward the Extractor until the inlet is positioned directly 
under the outlet elbow. Slip the three-inch pipe nipple up through the tank inlet opening and 
thread into the outlet elbow. Make sure that the basket is positioned directly under the 
Extractor outlet. 
 
Level the tank by shimming at anchor bolt holes to insure full and solid support.  Bolt the tank 
according to the type of floor, using through bolts or expansion shields.
