Model T32335 (Mfd. Since 11/20)

— Turn screw half turn clockwise to increase 

both settings.

— Turn  screw  half  turn  counterclockwise  to 

decrease both settings.

6.  Install pressure switch cover.

7.  Connect  machine  to  power,  start  compres-

sor,  and  cycle  compressor  through  cut-in/
cut-out  pressures.  If  compressor  does  not 
automatically  turn 

OFF  at  115  PSI,  turn 

machine 

OFF  before  pressure  reaches  120 

PSI. Adjust pressure switch settings until cut-
out pressure is 115 PSI or lower.

Adjusting Only Cut-Out Setting

If only the maximum tank pressure setting needs 
to  be  adjusted,  then  follow  these  steps.  Keep 
in  mind  that  the  allowable  pressure  differential 
between  cut-in  pressure  and  cut-out  pressure 
must be kept between 30–40 PSI. Exceeding this 
range can cause the compressor to overheat.

5.  Adjust screw shown in Figure 36 to change 

maximum tank pressure setting.

— Turn screw half turn clockwise to increase 

tank pressure.

— Turn  screw  half  turn  counterclockwise  to 

decrease tank pressure.

6.  Install pressure switch cover.

7.  Connect  machine  to  power,  start  compres-

sor,  and  cycle  compressor  through  cut-in/
cut-out  pressures.  If  compressor  does  not 
automatically  turn 

OFF  at  115  PSI,  turn 

machine 

OFF  before  pressure  reaches  120 

PSI. Adjust pressure switch settings until cut-
out pressure is 115 PSI or lower.

To adjust only cut-out setting:

1.  Operate  compressor  and  record  cut-in  and 

cut-out pressures.

2.  DISCONNECT MACHINE FROM POWER!

Releasing air through drain valve can 

be extremely loud. Protect hearing with 

ANSI-approved hearing protection while 

performing following step.

3.  Use  safety  relief  valve  to  reduce  tank  pres-

sure to less than 10 PSI. 

4.  Remove  Phillips  head  screw  shown  in 

Figure 35 to remove pressure switch.
