Model T32002 (Mfd. Since 02/20)

SECTION 6: MAINTENANCE

For optimum performance from this machine, this 
maintenance schedule must be strictly followed.

Ongoing
To minimize your risk of injury and maintain proper 
machine operation, shut down the machine imme-
diately if you ever observe any of the items below, 
and fix the problem before continuing operations:

• 

Loose mounting bolts.

 

Cracked or loose grinding wheel.

 

Damaged buffing wheel.

 

Worn or damaged wires.

 

Any other unsafe condition.

Schedule

To reduce risk of shock or 

accidental startup, always 

disconnect machine from 

power before adjustments, 

maintenance, or service.

The  bearings  on  the  T32002  are  permanently 
sealed and require no lubrication.

Lubrication

Cleaning  the  Model  T32002  is  relatively  easy. 
Vacuum excess debris, and wipe off the remain-
ing dust with a dry cloth.

Cleaning & 

Protecting

The  grinding  wheel  should  be  inspected  before 
every  use.  Use  the  ring  test  method  noted  in 

Inspecting Grinding Wheel on Page 21 to verify 
the structural integrity. Take care in storing grind-
ing wheels to keep them free from potential dam-
age by being dropped or having other items drop 
on them.

Replace the wheel when the tool rest has no more 
adjustment  and  the  gap  has  exceeded  the  safe 
limit.

Grinding Wheels

Depending  on  the  type  of  grinding  you  do,  the 
grinding wheel may require periodic dressing. 

Several different kinds of wheel dressing devices 
are  available.  Dressing  restores  the  abrasive 
quality  of  the  wheel  surface  and  squares  up  the 
wheel edge. 

Refer  to  the  instructions  that  accompany  your 
dressing  accessory  for  complete  details  on  how 
to properly dress a wheel.

See  available  wheel  and  diamond  dressers  on
