MAINTENANCE
10.3 Fan Housing Liner Replacement
To prevent damage due to air-blast from the fan, a rubber liner is attached to the inside of the fan housing.
Check the liner regularly for holes, tears or pitted areas, as well as for worn liner bolts. If the fan housing is
exposed to direct wear because of a worn liner, the liner should be replaced. The rubber liner is relatively
inexpensive compared to replacing the fan housing.
Disassembly:
1. Follow Steps 1-7 of ‘Disassembly’ in Section ‘Fan Replacement.’
2. Unscrew the 3/8” nuts from around the outside of the fan housing and remove the elevator bolts holding
the rubber liner in place. Note the condition of the fan housing liner bolts. Worn bolts should be discarded
and replacements used upon reinstallation.
3. Remove the worn liner in one piece if possible. Save it to use as a template to mark the new liner’s hole
pattern.
Replacement:
1. Place the old liner on top of the replacement liner material and mark the length and hole pattern with spray
paint.
2. Cut the liner material to length and use a hole punch or drill to make the holes.
3. Notice that the replacement liner hole pattern is different at each end. Be sure you position the liner so that
its holes match the hole pattern of the fan housing.
4. Start by installing the elevator bolts which hold the rubber liner to the top of the fan housing, and then
continue installing the remainder of the elevator bolts, working out and down from the top of the fan
housing.
5. Apply silicone to the outer edges of the liner and to the heads of the elevator bolts to prevent premature
wear and extend the life of the bolts and fan housing.
6. Check the fan blades for wear and replace the fan if needed. To replace fan, follow Steps 1-16 in
‘Replacement’ of the preceding Section ‘Fan Housing Replacement’.
11. SWEEPING HEAD
The sweeping head is dependent upon forced air and vacuum to achieve debris pickup. Without proper
maintenance and replacement of parts due to normal wear, the sweeping head cannot provide the desired
sweeping results.
The Schwarze SuperVac Updraft is equipped with a sweeping head. Many of the maintenance procedures
outlined in the following sections apply to the sweeping head.
