Mounting

due  to  the  significant  forces  exerted  on  the 
sander  during  operation,  you  must  mount  it  to  a 
workbench. We recommend that you use one of 
the  following  methods  to  secure  your  sander  to 
the workbench before using it.

the  strongest  mounting  option  is  a  "through 
Mount" where holes are drilled all the way through 
the  workbench,  and  hex  bolts,  washers,  and 
hex  nuts  are  used  to  secure  the  sander  to  the 
workbench.

another  option  for  mounting  is  a  "direct  Mount" 
where the machine is simply secured to the work-
bench with a lag screw.

the source of an unusual noise or vibration, stop 
using  the  machine  immediately,  then  review
