MAINTENANCE
7.1 Replacement
1.
Use a gasket scraper, putty knife or screwdriver to remove the seal from its sweeper component. Get the
metal surface as clean as possible. Be sure it is free of all dirt, old glue, and seal material.
2.
Liberally apply a coat of weather-strip-type adhesive onto the new seal and body component. Allow the
adhesive to set up for several minutes (follow the adhesive manufacturer’s instructions) and then put the
new seal in place.
8. HOPPER
The hopper is one of the central components of the SuperVac Updraft sweeper. To ensure the longest possible
useful lifetime, it is extremely important to clean it after each shift and to let it air dry with the hopper up
whenever possible.

MAINTENANCE
9.1 Drive Belt
On the rear of the auxiliary engine is the belt which drives the fan shaft. Check the belt tension periodically.
This is accomplished by pressing down on the belt halfway between the two pulleys. With 30 lbs of pressure
(the approximate equivalent of very firm pressure from on it from your thumb), the belt should deflect about 1/
2”. An average belt, over the course of its life, will stretch slightly and the belt will need adjustment. This will be
especially true during the first 30-75 hours of operation.
Adjustment:
The auxiliary engine, along with its engine skid, can be moved in the direction of the fan shaft (to loosen or
remove the belt) or away from the fan shaft (to tighten the belt).
1.
Remove the belt guard.
2.
Loosen (do not remove) the bolt which holds each of the four outer corners of the engine skid to the top of
the power module platform.
3.
Locate the threaded rods known as jack screws.
NOTE:
Before adjusting the jackscrews, it is always a good idea to mark the present position of the engine
skid, both at the front and rear, on the power module platform. This will allow you to determine how far the
engine skid has been moved and whether the center line of the auxiliary engine is still parallel with the fan
shaft.
NOTE:
Once the four tie-down bolts have been tightened, release the tension on the jackscrews.
4.
Loosen the jackscrews' jam nuts.
5.
By running the adjustment nuts in or out, the engine skid may be moved toward or away from the shaft.
Alternate adjusting the jackscrew nuts front to rear so that movement of the engine skid is even and the
engine skid does not become misaligned. If you turn the front jackscrew three revolutions, then turn the
rear jackscrew three revolutions.
6.
When proper belt tension is achieved, re-thread the loose adjustment nuts tightly against their power
module platform tabs. (If you're adjusting the engine away from the fan shaft, these would be the inner
adjustment nuts; toward the fan shaft, these would be the outer adjustment nuts.) Tighten any loose jam
nuts back against their respective adjustment nuts.
7.
Tighten the four tie-down bolts at the corners of the engine skid.
