  Move the high/low range lever back to the 

right side of the head (see Figure 33.

 Make sure that the range lever is as far 

back as it will go before starting the spindle 
rotation.

 When the spindle speed range selector and 

high/low range lever are correctly set, they 
will be in the opposite direction from each 
other.

 Move the high/

low range lever forward so that it is pointing 
to the front of the head.

 Make sure that the range lever is as far 

forward as it will go before starting the 
spindle rotation.

 

Pull the knob of the spindle speed range 
selector out to disengage the detent pin, 
rotate the selector clockwise to the rear 
position, then release the knob.

 Make sure the selector detent pin is well 

seated before starting the spindle rotation.

 Perform 

the 

Clutch procedure as instructed on Page  
to make sure the front spindle pulley and 
pinion are properly seated into the bull gear.

When setting the mill to use the high spindle 
speed range, the front spindle pulley must mesh 
with the spindle clutch. Otherwise, you will hear 
an unusual grinding when spindle rotation is 
started and damage to these components could 
be the result.

  DISCONNECT MILL FROM POWER!

  Set the spindle speed range control(s) for the 

mill as instructed on the previous pages.

— If you hear/feel the front pulley drop 

into the spindle clutch when you set the 
control(s), this procedure is complete and 
you can continued with spindle speed 
setup.

— If you do not hear/feel the front pulley 

drop into the spindle clutch when you set 
the control(s), continue with Step 3.

 The following step takes experience and 

patience to complete properly.

  Firmly grasp the spindle, then quickly rotate 

it in a back-and-forth motion until you hear/
feel the front pulley drop into the spindle 
clutch.

— If 

Step 3 was not successful, use the 

spindle speed range control(s) to re-set 
the mill to the low range, then repeat 
Step 3 until you are certain that the 
front pulley is seated into the spindle 
clutch.
