Adjusting 

Spring Tension

The  spring  tension  for  automatic  quill  recoil  has 
been pre-set at the factory. In most cases, it will 
never  need  to  be  re-adjusted  during  life  of  the 
machine.  However,  if  quill  stops  automatically 
recoiling, the spring may need to be adjusted for 
additional tension. If it does need adjustment, the 
spring  housing  is  located  on  the  left  side  of  the 
headstock.

4.   Hold  spring  lock  cover  against  side 

of  headstock  so  the  cover  stays  splined 
with  locking  lug,  as  shown  in 

Figure  41

then

  loosen  jam  nut  and  loosen  cover  nut 

approximately 

1

4

" each.

5.  Wearing gloves, pull spring cover (see Figure 

41) outward just enough to disengage spring-
cover lock slot from locking lug.

To adjust spring tension:

1.  DISCONNECT MACHINE FROM POWER!

2.  PUT ON SAFETY GLASSES!

3.  Wipe  any  oil  off  spring  lock  cover  so  it  does 

not  slip  in  your  fingers  when  you  hold  the 
cover from spinning (see 

Figure 41).

If the return spring should 

come loose from the spring 

cap and rapidly unwind, 

laceration or impact inju-

ries could occur. Always 

wear heavy leather gloves 

and safety glasses when 

adjusting the return spring 

tension.

7.   Engage next available spring-cover lock slot 

with  locking  lug  (see 

Figure  41)  and  hold  

spring lock cover tightly to side of headstock.

8.   Tighten  cover  nut  against  spring  cover 

just  until  nut  stops,  and  then  back  off  nut 
approximately 

1

3

 turn. 

10.  Check return spring tensioning by downfeed-

ing  spindle.  Spindle  should  return  quickly 
when downward pressure is released.

— If  spindle  does  not  retract  quickly,  repeat 

Steps 4–9,  and  re-check  tension  until 
return speed is adequate.

9.   Hold cover nut and tighten jam nut to cover 

nut.

6.  Rotate  cover  counterclockwise  to  increase 

tension,  or  let  cover  slowly  unwind  in  clock-
wise  direction  to  reduce  spring  tension  (see 

Figure 40).
