WARNING:    Before proceeding with any maintenance, disconnect power source. 

If the vacuum pump takes too long to attain full vacuum, it may require maintenance.    Replace 

the diaphragm, gasket/flap valves or (when preferable) the entire head assembly

21

  (see 

REPLACEMENT PARTS LIST), as necessary to obtain acceptable pump performance. 

CAUTION:    Do not over-tighten the head screws, because this may damage the 

threads in the pump body. 

Replacing the Diaphragm 

1)  Remove the four head screws (1) and lock washers (2), and remove the head assembly 

(3―7). 

2)  Remove the diaphragm retaining screw (8), diaphragm (9) and rubber O-ring (10). 

Note:    Be sure to save the flat washer located between the O-ring and the connecting rod 

(11).    Also take note of the diaphragm orientation for reassembly. 

3)  Replace the diaphragm, rubber O-ring and diaphragm retaining screw.    Reinstall the flat 

washer in its original position. 

4)  Reverse the steps above for reassembly, as shown 

in the illustration. 

Replacing the Gasket/Flap Valves 

1)  Remove the four head screws (1) and lock washers 

(2), and remove the head assembly (3―7). 

2)  Invert the head and remove the two valve plate 

screws (7).    Remove the valve plate (6) to access 
the gasket/flap valves. 

3)  Replace the gasket/flap valves (5) and reverse the 

steps above for reassembly, as shown in the 
illustration.    Use the alignment pin (15) to ensure 
proper fit between the head and valve plate. 

Replacing the Head Assembly 

1)  Remove the four head screws (1), lock washers (2) 

and head assembly (3―7). 

2)  Replace the head assembly, and reverse the steps 

above for reassembly, as shown in the illustration.

CAUTION:

    Depending on the product, the head assembly (3―7) may be rotated to an orientation different from the one 

shown.    When removing the head assembly, always take note of its orientation and install it the same way during reassembly.   
Make sure that the intake and exhaust ports remain in their original positions.
