FIG. 4
installing Rubber Foot Strip and Wheels
L.........]
It may be necessary to brace or support one
end of the outfit when attaching the wheels
because the air compressor will have a
tendency to tip.
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 intoplace.
(See page 14 key no. 39.)
_-.The leg bracket on the underside of the air compres-
sor tank has 2 holes 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 Shut-off Valve
ADAPTER
SHUT-OFF
VALVE
SWIVEL
CONNECTION
Apply a small amount of pipe sealant (not supplied) to
the tapered pipe threads on the adapter and tighten into
the manifold. Install the swivel connection end of the
shut-off valve to the straight threaded end of the adapter
(pipe sealant is not required) and tighten this connec-
tion. See photo above.
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 walls or other obstructions that could
interfere with the flow of air through the fan bladed fly-
wheel. The air compressor crankcase and head are
3esigned with fins to provide proper cooling.
If humidity is high, a Sears air filter can be installed to
remove excessive moisture, and oil vapor from the air.
Closely follow the instructions packaged with the filter
Forproper installation, it must be installed as close as
oossible to the accessory.
Extension Cords
Foavoid voltage drop and power loss to the motor, use
._xtraair hose instead of an extension cord.
f an extension cord must be used:
use only a 3-wire extension cord that has a 3-blade
grounding plug and a 3-slot 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 g. x 50' tg. ext. cord at your local Sears Serv-
ice 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
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.
77, pg. 15) and slowly add a special compressor oil such
as Sears 9-16426 or SAE 20-20W SF or SG motor oil
until it is even with the top of the oil 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 oil flows
very slowly. If the oil is added too quickly, it will overflow
and appear to be full. Crankcase oil capacity is !6 fluid
ounces. Under winter-type conditions use SAE 10W oil.
Multi-viscosity oil, 10W30, will leave carbon deposits on
critical components reducing performance and com-
pressor life. Replace oil fill plug.
