Sears 919.17621, 919.17632, 919.17633, 311 owner manual Adapter, Operation

It may be necessary to brace or support one end of the outfit when attaching the wheels and the foot extension bracket because the outfit will have a tendency to tip over before wheels are attached.

1.Insert the handle into pockets under the tank Saddle; Put one set screw (28) through hole in one side of tank saddle and tighten down on handle.

2.Remove the protective paper strip from the adhesive backed rubber foot strip (47). Attach the rubber foot strip to the bottom of the foot extension bracket (45). Press firmly into place.

3.Attach foot extension bracket (45) to the air tank bracket. Use one cap screw (46) one Iockwasber (83) and one hex nut (44) at each end. Tighten.

4, Use one shoulder bolt (41) and one locking hex nut

(42)for attaching each wheel. Use the lower set of holes for the 8"wheel (40). Use the upper set of holes for the 10" wheel (40A). Tighten securely,

I[V;,PROPER GROUNDING CAN RESULT INA

R!SK OF ELECTRICAL SHOCK, IN THE -VENT OF A SHORT CIRCUIT, GROUNDING R-:)UCES THE RISK OF SHOCK BY PRO-

VIDING AN 5SCAPE WIRE FOR THE ELEC- TRIC CURRENT, THIS COMPRESSOR MUST

BE PROPERLY GROUNDED. READ THE

FOLLOWING iNSTRUCTIONS.

1.The compressor is equipped with a cord having a grounding wire with an appropriate grounding plug.

The plug must be used with an outlet that has been properly installed and grounded in accordance with all local codes and ordinances. The outlet must have

the same configuration as the plug, DO NOT USE AN

ADAPTER.

2, If repair or replacement of the cord or plug is ever necessary, do not connect the grounding wire to

either flat blade terminal. (The grounding wire has insulation with an outer surface that is green- with or without yellow stripes.)

3.Do not modify the plug that has been provided, If it does not fit the available outlet, the correct outlet should be installed by a qualified electrician.

If these grounding instructions are not completely understood, or if in doubt as to whether the compressor

is propedy grounded, have the installation checked by a qualified electrician or serviceman.

Start-Up Procedures

All units are shipped without oil. Serious damage may result if the following break-in instructions are not closely followed. This operation has to be completed only once when first putting the unit in service,

PlaCe unit on a level surface. Remove oil fillplug (51) and

slowly add a special compressor oil such as Sears 9H6426 or SAE 20=20W SF motor oil until it is even with

the top of the oil fill hole. When filling the crankcase, the oil flows into itvery slowly. If the oil is added too quickly,it will overflow and appear to be full. (It takes 16 fluid ounces of oil ot fill the crankcase.) Under winter-type conditions use SAE 10W oil. Multi-viscosity oil (10W30) may be used but will result in carbon deposits on critical components and reduce performance and compressor

life. Replace oil fill plug (51). Plug the compressor into the correct power source. Start the compressor by

switching the ON-AUTO/OFF switch (19) to the ON-

AUTO position. Turn the regulator knob (23) clockwise fully to permit air to escape and prevent air pressure bui!dup in the air tank. RUN THE COMPRESSOR 30 MINUTES IN THIS MANNER TO LUBRICATE PIS- TONS AND BEARINGS. Shut off air with regulator knob

(turn counterclockwise) and let the unit pump up to cut off pressure. Turn the switch to "OFF" and check the oil

level; add oil if necessary, Turn switch to _ON" and the unit is ready for use. Connect the air hose to the air outlet connection (27) located on the front of the console. Refer to Figure 1.

OPERATION

Control Console

The control console (33) is located on the front of the unit. The air pressuro coming from the air tank is con-

trolled by the regulator knob (23). Turn the regulator knob clec_ise to increase pressure and countemlockwise to decrease pressure. To avoid minor readjustment after making a change in pressure setting, always approach the desired pressure from a lower pressure. When reducing from a higher to a lower setting, first reduce to some pressure less than that desired, then bring up to the desired pressure. Depending on the air flow require- ments of each particular accessory, the outlet regulated air pressure might have to be adjusted under flow condi- tions, Also on the console is the ON-AUTO/OFF switch, air outlet, safety valve and two pressure gauges. One gauge shows the air tank pressure and the other the outlet regulated pressure. Refer to Figure 2.
