CLEANING AUTO-START INFRARED SENSORS

Paper detection sensors are for maintenance-free 

operation. However, on rare occasions the sensors may 

become blocked by paper dust, causing the motor to 

run even when there is no paper present. 

NOTE: Two paper detection sensors are located 
in the center of the paper entry.

OILING SHREDDER

All cross-cut shredders require oil for peak performance. 

If not oiled, a machine may experience diminished 

sheet capacity, intrusive noise when shredding and 

could ultimately stop running. To avoid these problems, 

we recommend oiling shredder each time user empties 

waste bin.  

CAUTION! Use only a non-aerosol vegetable oil 

in long nozzle container, such as S-16094.

Follow oiling procedures below and repeat twice. 

2.  Press and hold forward ( ) 

for 2-3 seconds.
