Craftsman 919.17673 - Manual (Page 8)

It may be necessary to brace or support one
end of the outfit when attaching the wheels
b e c a u s e the air compressor w i l l h a v e a
tendency to tip.
Installing Rubber Foot Strip and Wheels
1. Remove the protective paper strip from the adhesive-
backed rubber foot strip. Attach the rubber foot strip to
the bottom of the air tank leg. Press firmly into place.
(See page 14 key no. 39.)
2. The leg bracket on the underside of the air compres­
sor tank has 2 hoies on each side for mounting the
wheels. Place one shoulder bolt through the hole in a
wheel. Next, push the bolt through the LOWER hole of
the leg bracket and screw on one hex locking nut. The
special locking nut does not turn freely. Tighten the
nut firmly until it contacts the leg. See pg. 14. The
outfit will set level if the wheels are properly installed.
installing Tank Pressure Gauge
Apply pipe sealant (not supplied) to the gauge threads
and install in the threaded opening in front of the
manifold. Refer to photo on pg. 6.
Installing Regulator
(Top View)
Use a small amount of pipe thread sealant (not
supplied) on all pipe thread joints. Install the
regulator on the end of the manifold using the
short pipe nippie. The arrow on the bottom of
the regulator must point away from the manifold
in order for the regulator to function property.
Next, install the gauge, adapter and plug in the
regulator. The plug is supplied with the regulator.
INSTALLATION AND BREAK-IN PROCEDURES
Location of the Air Compressor
Operate the air compressor in a clean, dry and well
ventilated area. The air filter must be kept clear of
obstructions which could reduce air delivery of the air
compressor. The air compressor should be located at
least 12" away from wails or other obstructions that could
interfere with the flow of air through the fan bladed fly­
wheel. The air compressor crankcase and head are
designed with fins to provide proper cooling.
If humidity is high, a Sears air filter can be installed on
the air outlet adapter to remove excessive moisture, and
oil vapor from the air. Closely follow the instructions
packaged with the filter for proper installation. It must be
installed as close as possible to the accessory.
Extension Cords
To avoid voltage drop and power loss to the motor, use
extra air hose instead of an extension cord.
If an extension cord must be used:
• use only a 3-wire extension cord that has a 3-blade
grounding plug and a 3-siot receptacle that will accept
the plug on the product.
• make sure the extension cord is in good condition.
• the extension cord should be no longer than 50 feet.
' the minimum wire size is 12 gauge (AWG), Sears #9-
83606, 12 gauge X 50' extension cord is available at
your local Sears Service Center. (Wire size increases
as gauge number decreases. 10 AWG and 8 AWG may
also be used. DO NOT USE 14 AWG or 16 AWG.)
Lubrication and Oil
CAUTION
Compressors are shipped without oil. Do
not attempt to operate this air compressor
without first adding oil to the crankcase.
Place unit on a level surface. Remove oil fill plug (Key no.
81, pg. 15) and slowly add a special compressor oil such
as Sears 9-16426 or SAE 20-20W SF motor oil until it is
even with the top of the oi! fill hole. (It must not be allowed
to be lower than %" - 6 threads down - from the top, at
any time.) When filling the crankcase, the oi! flows very
siowiy. If the oil is added too quickly, it will overflow and
appear to be full. Crankcase oil capacity is 16 fluid
ounces. Under winter-type conditions use SAE 10W oil.
Multi-viscosity oil, 10W 30, will leave carbon deposits on
critical components reducing performance and com­
pressor life. Replace oil fill plug.
