2. Clean the AC drive fins:

a. Remove the AC drive box cover.

b. Blow the fins clean using compressed 

air at a pressure of 60–90 psi or by 
using canned compressed air. Use care 
to avoid damaging cooling fan or 
other components.

No amount of visible foreign matter 

should be allowed to accumulate on the 
fins or the finger guard.

3. Use the following procedures to determine 

if V-belts require replacement or 
adjustment. Call a qualified service 
technician in either case.

a. Check V-belts for uneven wear and 

frayed edges. 

b. After disconnecting power to the 

machine and removing all panels 
necessary for access to the drive belt, 
use the following method to verify that 
V-belts are properly tensioned. 

See Figure 28. Belt deflection should 
be measured as close to the center of 
the span length as possible. A set force 
should be applied in the center of the 
span length, as specified in the 
following table. Belt tension is adjusted 
by turning the setscrew on the idler 
pulley. Turning the screw clockwise 
tightens the belt, and vice versa.

c. Verify that V-belts are properly aligned 

by checking pulley alignment. Place a 
straightedge across both pulley faces. 
The straightedge should make contact 
with the pulleys in four places. See 
Figure 29.
