10. Check the alignment of the vacuum fan
sheave with the jackshaft sheave. If they are
not lined up, loosen the fan bracket
mounting bolts, align the sheaves, and
retighten the mounting bolts.
11. Check the vacuum fan belt tension. There
should be 0.18 in (5 mm) deflection from a
force of 8 lb (4 kg) applied at belt span
midpoint. To adjust tension, loosen the fan
bracket mounting bolts, slide the fan bracket
forward to loosen or backward to tighten the
belt, and retighten the mounting bolts.
Recheck the sheave alignment.
12. Make sure the main brush belt clears the
belt guard.

13. Check the alignment of the small jackshaft
sheave to the main brush sheave. If they are
not lined up, loosen the jackshaft bearing
locking collars, align the sheaves, and
tighten the locking collars. The belt is
automatically tensioned by an idler spring
assembly.
14. Measure the length of the jackshaft belt
tension spring. It should be 6.5 in (165 mm).
To adjust the spring length, unhook the
spring. Loosen the adjustable idler bolt and
slide the idler forward to reduce spring
length or backward to increase spring
length. Tighten the adjustable idler bolt and
rehook the belt tension spring. Repeat
procedure as required.
15. Close the seat support.
STATIC DRAG CHAIN
The static drag chain prevents the buildup of
static electricity in the machine. It is attached to
the rear skirt retaining strip.
Make sure that the chain is making contact with
the floor at all times.
