Tip & Tool Stand 

The Tip & Tool Stand can be mounted to the power source. If the system will be placed on the workbench, this 
is recommended. If the power source is to be mounted under the workbench or shelf, the Tip & Tool Stand 
should not be mounted to the power source. 
 

1. To attach the stand to the power source: 

a) Insert the 2 Mounting Screws (head first) into the power 

source mounting slots (plastic case shown). Slide the screws 
toward the rear of power source. 

b) Place the Tip & Tool Stand beside the power source. Insert 

ends of the 2 Mounting Screws into the 2 Tip & Tool Stand 
mounting holes shown. 

c) Install a Thumb Nut onto the end of each Mounting Screw and 

tighten Thumb Nuts. 

 

2. Place the handpiece into its Tip & Tool Stand.
