Model H8253 Air Belt Sander

-9

-

Keeping  the  sander  clean  is  vital  to  its 
operation  and  leads  to  longer  tool  life. 
After  every  use,  clean  and  inspect  the 
sander.

• 

Wipe  the  housing  with  a  dry  cloth,  or 
blow off the dust and debris with com-
pressed air.

• 

Check  for  damage  to  tooling,  hoses, 
housing or other accessories.

Do  not  allow  dust,  chips,  sand,  etc.  into 
the air connectors or into the body of the 
sander  air  motor;  this  may  result  in  leaks 
and  damage  to  the  sander  and  the  air 
couplings.

Always  disconnect  air  from  sander 
whenever  servicing!  During  mainte-
nance, a sander connected to air may 
start  accidentally,  causing  personal 
injury!

MAINTENANCE 

Cleaning

Lubrication

The  air  sander  MUST  have  2-6  drops  of 
oil dropped directly into the air inlet before 
and after each use and before storage.

After oiling, remove the sanding belt, then 
run  the  sander  to  purge  excess  oil.  Wipe 
the  tool  down  with  a  rag,  re-install  the 
sanding belt, then begin sanding. 

Another  option  to  manual  oiling  would  be 
to install a lubricator in your air compressor 
line. If your air compressor line already has 
a lubricator, then regular lubrication of your 
sander  will  not  be  necessary.  Just  make 
sure there is always oil in the lubricator.
