_J Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals
known (to the State of California) to cause cancer, birth defects or other
reproductive harm. Some example of these chemicals are:
• lead from lead-based paints
• crystalline silica from bricks and cement and other masonry products
• arsenic and chromium from chemically-treated lumber
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, always wear
MSNA/NIOSR approved, properly fitting face mask or respirator when using
such tools.
When using air tools, basic safety precautions should always be followed to
reduce the risk of of personal injury.

human consumption. In order to use air
)roduced by this compressor for
breathing, suitable filters and in-line
safety equipment must be properly
installed. In-line filters and safety
equipment used in conjunction with the
compressor must be capable of treating
air to all applicable local and federal
codes prior to human consumption.
Work in an area with good cross
ventilation. Read and follow the safety
instructions provided on the label or

Become familiar with these terms
before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per
minute; aunit of measure of air
delivery.
PSlG: Pounds per square inch
gauge; a unit of measure of pressure.
Code Certification: Products that
bear one or more of the following
marks: UL, CUL, ETL, CETL, have
been evaluated by OSHA certified
independent safety laboratories and
meet the applicable Underwriters
Laboratories Standards for Safety.
Cut-In Pressure: While the motor is
off, air tank pressure drops as you
continue to use your accessory.
When the tank pressure drops to a
certain low level the motor will restart
automatically. The low pressure at
which the motor automatically
restarts is called "cut-in" pressure.
Cut-Out Pressure: When an air
compressor is turned on and begins
to run, air pressure in the air tank
begins to build. It builds to a certain
high pressure before the motor
automatically shuts off - protecting
your air tank from pressure higher
than its capacity. The high pressure
at which the motor shuts off is called
"cut-out" pressure.
Branch Circuit: Circuit carrying
electricity from electrical panel to
outlet.
This unit is capable of powering the following Accessories. The accessories are
available through the current Power and Hand Tool Catalog or full-line Sears
stores.

This air compressor pump is capable
of running continuously. However, to
prolong the life of your air
compressor, it is recommended that a
50%-75% average duty cycle be
maintained; that is, the air
compressor pump should not run
more than 30-45 minutes in any given
hour.

Tools Required for Assembly
1-9/16" socket or open end wrench
1 - electric drill
Unpacking
1. Remove all packaging.
It may be
necessary to brace
or support one side of the air
compressor when removing the
pallet because the air compressor
will have a tendency to tip.
2. Remove and discard the (4)
screws and washers holding the
compressor to the pallet.
3. With the help of another person
carefully remove air compressor
from pallet and place on a level
surface.
Adding Oil To Pump
Compressors are
shipped without oil.
A small amount of oil may be
present in the pump upon receipt
of the air compressor. This is due
to plant testing and does not mean
the pump contains oil. Do not
attempt to operate this air
compressor without first adding oil
to the crankcase. Serious damage
can result from even limited
operation unless filled with oil and
broken in correctly. Make sure to
closely follow initial start-up
procedures.
I_[_I_ Use air compressor
oil only. Multi-
Viscosity motor oils, like lOW 30,
should not be used in an air
compressor. They leave carbon
deposits on critical components,
thus reducing performance and
compressor life.
NOTE: Use an air compressor oil
such as Sears item number 9-16426
or SAE-20 (API CG/CD) heavy duty
motor oil. Under extreme winter
conditions use SAE-10 weight oil.
To Add Oil
Drain tank to
release air pressure
before removing the oil fill cap or
oil drain plug.
1. Place unit on a level surface.
2. Remove oil fill plug (A) and
slowly add compressor oil until it
is even with the top of the oil fill
hole. NOTE: Do not allow oil to
be lower than 3/8" (6 threads)
from the top at any time. When
filling the crankcase, the oil flows
very slowly into the pump. If the
oil is added too quickly, it will
overflow and appear to be full.
NOTE: Crankcase oil capacity is
approximately 16 fluid ounces.
3. Replace oil fill plug.
