OVERLOADING DEBRIS HOPPER AND WEAR ON VACUUM HOUSING
OVERLOADING DEBRIS HOPPER
Smithco Sweeper-Vacs are designed to carry the following maximum loads:
Model 72-000 Big Vac
1500 lbs. (608 kg)
PLEASE NOTE THE FOLLOWING:
1. Loads heavier than that will damage the unit.
2. Such damage is not covered by warranty.
3. Overloading is particularly easy when collecting aerifier cores.
4. The hoppers on the Big Vac and V62 are large in order to hold 7 and 4 cubic yards respectively, of thatch, grass
clippings, leaves and trash.
5. They will not hold 7 or 4 cubic yards of aerifier cores.
6. The maximum depth (in the debris hopper) of aerifier cores is:
Model 72-000 Big Vac
12 in. (30 cm)
VACUUM HOUSING WEAR
The Big Vac & V62 are fitted with a wear resistant liner in the vacuum housing. This will provide additional housing life. Be
sure the following points are explained to the user:
1. The vacuum housing and impeller must be cleaned each time the unit is used so the housing liner is inspected
daily. Only Smithco Sweeper-Vacs provide a clean out/inspection port for easy inspection and cleaning.
2. When bare steel is visible at any point in the housing lining, the lining must be replaced. It is expected the liner will
wear and be replaced. It is a vast improvement over competitive units with no liners.
3. Replacement of the liner or the vacuum housing due ti wear is normal and is not covered by warranty.
4. Collection of aerifier cores causes extreme wear on the liner (and if unchecked, on the housing).
5. Caution users that, while Smithco Sweeper-Vacs do an excellent job collecting cores, the lining (and the housing)
will wear quickly in such use.
RUBBERIZED BOOT
The rubberized boot between main unit and sweeper head is subject to wear and damage from debris. Unless defective,
replacement of this boot is not covered by warranty.
