handling it is important to prevent spills).  Emergency pump shutdown is  

possible as follows: 

 

(1) Place pump hydraulic control lever in neutral. 

(2) Shut down hydraulics.  

(3) Close discharge valve. 

 

v) 

Operate the pump in reverse for 5- 10 seconds to clear the piping and pump 

before terminating skimming operations and to prevent water from freezing in 

the pump. 

 

CAUTION

Before performing maintenance on the Desmi unit, shut down the hydraulic system.

Adjustment/Maintenance 

 

i) 

To adjust the tension on the belt use the following procedure: 

 

(1) Remove the forward pontoons to expose the belt adjustment slot in both 

sides of the hull. 

(2) Measure the belt catenary from the bottom center of the belt to the bottom of 

the belt box structure.   

(3) Unlock catenary adjustment screw locking nut.   

(4) Adjust the catenary of the belt by turning the adjustment screws so that the 

gap is 1 inch +/- ¼ inch. 

(5) Lock the adjusting nut. 

(6) Refasten the forward pontoons in place.
