8. PREVENTIVE MAINTENANCE

Wear appropriate "leather" gloves when performing maintenance or cleaning up the product, in order to
avoid injuries.
ATTENTION
recommendations below:
1. Daily
A. Before draining the tank, check its pressure, the maximum draining pressure is 10psi.
B. Drain the condensate (water) from within the tank through the purger (Figure 8.1).
C. Check if there's an abnormal noise in the compressor. If the problem persists after the corrective actions are
performed, contact the nearest SCHULZ AUTHORIZED DEALER.
D. Check the oil level and add oil if necessary before switching on the compressor. The oil level must be between
the maximum and minimum marks of the oil gauge dipstick (For oiled compressors) (Figure 8.6). For compressor
model MSW 60+Fort the oil view sight shall be read according to Figure 8.7.

3. Monthly
A. Check the pressure switch (Figure 8.3);
B. Have an electrician inspect electrical connections to retighten if necessary and verify the integrity of the
electric wires;
C. Check the alignment between the sheave and flywheel, belt tension and check state of use. For the products up
to 1hp belt deflection must be up to 4 mm with force/weight of 1kg. For larger products, deflection in the middle
point of the belt will be from 9 to 13mm with force/weight of 4kg.
D. Inspect transmission belts and electric motor. To check, remove the belt guard. After inspection, mount the
guard with fixing screws (Figure 8.4 and 8.5). Replace belts whenever necessary.
B. Check the tank load time. If above 20% in relation to what is indicated in Table TECHNICAL CHARACTERISTICS
have the piston rings replaced.
