Cumberland has long recognized the importance of safety and has 
designed and manufactured its equipment with operator safety as a 
prime consideration. We expect you, as a user, to abide by the 
foregoing recommendations in order to make operator safety a 
reality. 

 

SAFETY IS NO ACCIDENT 

 

1-2 Safety 

Procedures 

1-2-1  Guidelines for Moving the Granulator 

To lift and move the granulator safely and correctly, cover any 
sharp corners or edges, and use the type of equipment that has the 
most appropriate features and capacity. 

Before lifting, check that there are no items that could fall during 
lifting. 

Before positioning the granulator, check that the floor is level and 
is strong enough to support the load, that there is adequate space in 
the installation area to allow the movement of equipment necessary 
to the task and to enable any necessary maintenance work to be 
carried out unhindered.  

1-2-2  Clearing a Jammed Cutting Chamber 

1.

 

Disconnect and lockout power. 

2.

 

Be certain that the rotor is motionless. 

3.

 

Open the front panel and remove the bin. 

4.

 

Unscrew the screw knob, which keeps the hopper and screen 
cradle in place. 

5.

 

Remove the screen.
