Be_t - Replacement

SERIOUS _NJURY OR DAMAGE MAY OCCUR _FPARTS OF THE BODY OR LOOSE _TEMS GET CAUGHT IN MOVING PARTS. NEVER OPERATE THE OUTFIT WITH THE BELT GUARD REMOVED, THE BELT GUARD SHOULD BE REMOVED ONLY WHEN THE CO_4PBESSOB _SUNPLUGGED,

To Replace Belt:

f. Unplug compressor.

3.The motor is mounted on a special base, By ioosenin9

the wing nut at the motor hold down ptate, the motor can be tilted to allow for easy removal of the belt.

4.Remove belt and replace.

NOTE

The belt must be centered over the grooves on the flywheel and motor pulley.

5.Tighten the wing nut until it makes contact with the washer plus one additional turn.

6.Replace the front of the beltguard.

To Adjust Be_t Tension:

Tighten the wing nut until it makes contact with the washer plus one additional turn.

Pulley and Flywheem = Alignment

The compressor flywheM and motor puIley grooves must be in-line (in the same plane) within 1/32" to assure belt alignment within grooves. To check alignment, dis- connect electrical power and remove the beltguard. Place a straightedge against the outside of the flywheel and measure the distance from it to the nearest groove. Alignment is achieved when the other end of the straigh- tedge is within 1/32" of the measured dimension at the pulley grooves.

TROUBLESHOOTING GUIDE

PERFORMING REPAIRS MAY EXPOSE VOLTAGE SOURCES_ MOVING PARTS_ OR COMPRESSED A_R SOURCES PERSONAL _NJURY MAY OCCUR. PRIOR TO ATTE_IPT_NG ANY REPAIRS THE COMPRESSOR MUST BE UNPLUGGED, AND A_R TANK PRESSURE REUEVED° NEVER OPERATE THE UNiT W_TN THE BELT GUARD REMOVED°

PROBLEM

Excessive tank pressure - safety valve pops off.

CAUSE

Pressure switch does not shut off motor when compressor reaches "cut-out" pressure.

CORRECTION

Move the pressure switch lever to the "OFF" posi- tion. If the outfit doesn't shut off, and the ebctricai

contacts are welded together, replace the pressure switch.

If the contacts are good, check to see if the pin in the bottom of the pressure retief vane is stuck, if it does not move freely, reptace the valve.

Pressure switch "cut-out" too	Return the outfit	to	the Sears Service Center to
high.	check and adjust	or	replace switch.

Air leaks at fittings "Tubefittings are not tight enough.

Tighten fittings where air can be heard escaping. Check fittings with soapy water solution. DO NOT OVER-TIGHTEN.
