Note: Never operate saw without bearing cover in place. 
For normal conditions the grease should conform to the NLGI grade two consistency 
and be free of any chemical impurities such as free acid or free alkali, dust, rust, metal 
particles or abrasives. 
For best results, the bearings should be lubricated while in operation.   

Note: 
 Due caution for personal safety must be observed when servicing rotating 
equipment. 

 

If necessary to lubricate while the bearing is idle, refer to lubrication table for the 
maximum grease capacity for the bearings.

E. Pump 

 

The submersible pump is mechanically driven by the V-belts and the sealed bearings 
require no lubrication.  The pump is designed to run wet or dry, but for continued dry 
cutting, disconnect the pump. 
1.  Be sure to keep the pump clean - do not allow sediment to cake in the pump and 

clog it. 

2.  Keep all lines clean and running free. 
3.  Do not allow the Flex-cable to be pinched by the blade guard or anything else.  

Damage to the flex cable by pinching is not covered under any warranty
