equipped with a hook.
t. If a handle grip was incioded with
the unit, coat the inside of grip with
a thin film of soapy water. Push grip
onto handle.
2. Insert handle through shroud and
into baseplate as shown in Figure 1,
Handle must fit into special openings

Installation
LOCATION
When assembled, the tank must sit
level or slope slightly towards the drain
cock to allow the tank to drain
properly,
It isextremely important to install the
compressor in a dean. well ventilated area
where the surrounding air temperature
will not be morethan t00*F.
A minimum clearance of 18 inches
between the compressor and a wall is
required because objects could obstruct
air flow.

GROUNDING INSTRUCTIONS
1.This product is for use on a nominal
120 volt circuit and has a grounding
plug that looks llke the plug illustrated
in Fig.4. Make sure the product is
connected to an Outlet having the
same COnfiguration as the plug. ThiS
product must be grounded, in the
event of an electrical short circuit,
grounding reduces risk of electrical
shod( by providing an escape wire for
electric current. This product is
equipped with a cord having a
grounding wire with an appropriate
grounding plug. Plug must be plugged
into an outlet that is properly installed
and grounded in accordance with all
local codes and ordinances.

MOISTURE IN COMPRESSED AIR
Moisture in compressed air will
form into droplets as it comes from
an air compressor pump. When
humidity is high Or when a
compressor is in continuous use for
an extended period of time, this
moisture will collect in the tank.
When using a paint spray or
sandblast gun, this water will be
carried from the tank through the
hose, and out of the gun as
droplets mixed with the spray
material.
IMPORTANT: This condensation
will cause water spots in a paint
job, especially when spraying other
than water based paints. If
sandblasting, it will cause the sand
to cake and clog the gun,
rendering it ineffective. A filter in
the air line (MP3105). located as
near to the gun as possible, will
help eliminate this moisture.
