Description
This kit will replace pressure switch
assembly shown in Figure 1 with
pressure switch assembly shown in
Figure 2. Use this instruction guide for
assembly and operation information.
This guide is designed to supplement
the other instruction manuals included
with this unit. Carefully read all
manuals and safety information before
operating the compressor.
Components
Pressure switch - Auto/Off Switch - In
the "auto" position, the compressor
shuts off automatically when tank
pressure reaches the maximum preset
pressure. In the "off" position, the
compressor will not operate. This switch
should be in the "off" position when
connecting or disconnecting the power
cord from the electrical outlet or when
changing air tools.
Regulator - The regulator controls the
amount of air pressure released at the
hose outlet.
ASME Safety Valve - This valve
automatically releases air if the tank
pressure exceeds the preset maximum.
Removal of Existing Switch
1. Disconnect power and release all air
pressure from tank.
2. Remove existing pressure switch
cover screw(s), then remove cover.
3. Locate cut-outs on the back of
pressure switch (See Fig. 3). Insert
tip of small screwdriver into cutouts,
then push to release wires.

4. Remove ground screw (Fig. 3).
5. Remove strain relief screw (Fig. 3).
6. Pull unloader tube off existing
pressure switch. Remove screw
holding pressure switch to pressure
switch assembly. Then remove
switch from unit.
7. Disconnect unloader tube from
check valve.
8. Remove the remainder of pressure
switch assembly by unscrewing tank
fitting.
New Switch Installation
New switch must
have same maximum pressure as existing switch.
Pressure rating is listed on the bottom
of assembly.
1. Screw pressure switch assembly onto
tank.
2. Replace existing unloader tube
connection at check valve with new
quick connect supplied in kit.
3. Insert new unloader tube into quick
connect fitting on check valve.
4. Insert other end of unloader tube
into unloader valve on pressure
switch. Unloader tube can be cut if
supplied length is too long.
5. Loosen pressure switch cover screw,
then remove cover.
6. Two strain relief clamps will be
provided in the kit. Determine which
strain relief clamp to use based on
the diameter of the line cord.
7. Loosely attach strain relief clamp to
pressure switch with screw provided

Instrucciones para operar
(Continuación)
IMPORTANTE: Lea estas
instrucciones antes de operar
el compresor o podría dañarlo.
1. Coloque el presostato en “off” y
conecte el cordón eléctrico al
tomacorrientes (Fig. 6).
2. Coloque el presostato en “auto”
para operar la unidad (Fig. 6).
3. Gire la perilla del regulador
completamente en sentido contrario
a las agujas del reloj. El compresor
alcanzará la presión máxima fijada
de fábrica y se apagará.
4. Conecte el extremo de la manguera
a la perilla del regulador. Gire el
regulador en sentido horario para
aumentar la presión que sirve la
herramienta que está usando.
Este
presostato debe estar en OFF cuando vaya
a conectar o desconectar el cordón
eléctrico del tomacorrientes

9. Position white line wire underneath
screw head #1, then tighten screw to
secure wire. Position white motor
wire underneath screw head #2,
then tighten screw to secure wire
(See Fig. 4).
10. Attach green ground wire from line
cord to inside of pressure switch
with ground screw provided in kit.
Repeat procedure with green
ground wire from motor cord. (See
Fig.4
11. Place cover on pressure switch and
tighten cover screw.
12. Screw regulator onto pressure switch.
NOTE: Ensure air flow indicator arrow
on regulator body points away from
compressor (See Fig. 5).
13. Attach outlet pressure gauge to
regulator.
Operating Procedure
In the AUTO position, the compressor
pumps air into tank. It shuts off
automatically when unit reaches its
maximum preset pressure. In the OFF
position, the pressure switch cannot
function and the compressor will not
operate.
IMPORTANT: Read
instructions before operating
compressor or damage may
result.
1. Turn switch to OFF position and plug
in power cord (Fig. 6).
2. Turn switch to AUTO position to run
unit (Fig. 6).
3. Turn regulator knob fully
counterclockwise. Compressor will
build to maximum preset pressure
and shut off.
4. Attach end of hose to regulator
knob. Turn regulator clockwise to
increase pressure going to the tool
that is being used.
This switch should
be in the OFF
position when connecting or
disconnecting the power cord from the
electrical outlet.
