12 

The return spring is adjusted at the factory and 
should not need further adjustment. If adjustment 
is deemed necessary, follow the steps below 
while referring to Figure 12: 

1.  Unplug the machine from the power source. 

2.  Loosen two hex nuts (A). Do not remove. 

  Do not remove the coil spring 

cover (Step 3). The torsion spring will uncoil 
and can cause serious injury. 

3.  Firmly hold the coil spring cover (B). 

4.  Pull out the cover and rotate until the pin (C) 

on the return spring plate engages the next 
notch in the coil spring cover.  Turn the cover 
clockwise to decrease tension and counter-
clockwise to increase tension. 

5.  Tighten two hex nuts (A).  Do not over-tighten.  

Nuts should not contact the housing when 
tight.  The hex nuts should be tightened 
against each other. 

Install a light bulb, no larger than 60 watts into the 
socket accessed from beneath the head.  The 
rocker switch controls the light switch (D, Fig. 12). 

To tilt the table (refer to Figures 13 and 14): 

 

In the following steps, DO NOT OVER 
LOOSEN. This could result in the table 
assembly to separate from the column, fall 
and cause injury. 

1.  Using a 15/16" wrench, loosen the hex cap 

screw (B), located under the table, about one 
turn. 

2.  Pull the locator pin out.  

The pin may be seated quite tight; in which 
case turn the hex nut (B) clockwise with a 
3mm hex wrench to assist in extracting the 
pin 

Note: When the table is in any position other 
than level (0 degrees), the locator pin is not 
used. 

3.  Tilt the table to the desired angle by aligning 

the scale (in degrees) on the table (C) to the 
marker at the base of the bracket (D). 

4.  Tighten the hex cap screw (A).
