4. Bimonthly
A. Change the lubricant oil at every 200 (two hundred) hours, or whichever occurs first (Table 8.2).
5. Quarterly
A. Replace the air filter element at every 300 (three hundred) hours or quarterly, whichever occurs first.
B. Refasten the bolts of the compression unit by means of a torque meter and use a hand wrench for the nuts
and connections.
C. For oil-free compressors: Inspect the crankcase filter CSV 15, CSV 20 and CSV40, if blocked, clean with com-
pressed air jet or replace if damaged. For the CSW 40 and CSW 60, the crankcase filter must be replaced by a
SCHULZ AUTHORIZED DEALER. Clean the radiator for products CSW 40 and CSW 60, with compressed air jet at
a maximum pressure of 40 psi.
D. For MSW 60+Fort compressor: change the lubricant oil at every 400 (four hundred) hours ot three months,
whichever occurs first.
E. For MSW 60+Fort compressor: Inspect the restriction indicator and if indicate airflow abstruction, change the
filter elements (Figure 10.1).
6. Every six months (Only for oil-free compressors)
A. Lubricate the upper bearing of the rod assembled in the products MS 3, MSV 6, MSV 12 and MSV 18 and the
rod's ring CSA 6.5.
7. Every 1000 hours or 9 months (whatever occurs first)
A. Inspect the valves (located between the top of the cylinder and its head), if necessary, perform cleaning.
For oil-free compressors:
A. Lubricate the top bearings of the rods in products CSV 15, CSV 20, CSV 40, CSW 40 and CSW 60, and inspect
the bottom bearings of the rods.
B. Inspect the valves (located between the top part of the cylinder and its head), if necessary, perform cleaning.
C. Replace the bottom bearing of the rods in products MSV 6, CSA 6.5 and MSV 12.
D. Inspect and clean the check valve 16 (*).
E. Check the tank load time. If above 20% in relation to what is indicated in Table 1, have the piston rings re-
placed.
(*) When removing the compressor's valve, read the Chapter - SAFETY INSTRUCTIONS, item 9.
8. Yearly
A. Have pressure switch, manometer(s) and safety valve calibrated at a local technical standard and legislation
accredited body. This operation must be performed in a device that is not connected to the tank.
ATTENTION
The aforementioned instructions are based on normal operating conditions. If the com-
pressor is installed in a polluted area, perform inspections more frequently.
