1. Drain recovery tank. Be sure to dispose of waste in accordance with Federal, State
and Local laws and ordinances.
2. Remove and clean the filter bag if equipped with a filter box.
3. Check the system vacuum reading with the hose end in the sealed and unsealed con-
dition. Compare the readings from day to day to assure that the vacuum system is
not clogged nor has any air leaks.
4. Visually check that the blower oil is between the two red lines on the oil level sight

to sit for several minutes after shut down so the oil can drain back into the oil pan
for a proper reading.

7. Thoroughly check the entire machine to look for any fluid leaks, i.e.oil, coolant,
fuel, chemical, or water. Repair any leaks if necessary.
