  • Page 25 MSSM0201CE/9840AV (2 of 11) CRUSH/SEVER HAZARD—Tilting machines with tilt wheels/cradles may lunge forward or rearward and even fall over if the tilt wheels at the non-tilted end are raised out of their cradles—killing/injuring personnel and/or damaging prop- erty. NEVER manually tilt (lift) both ends of the machine at the same time. One end must always be seated in its cradle.

    “short circuit” exhaust connection near the clutch. The quick release valve is necessary for the clutch used on ® Milnor washer-extractors, and is furnished as original equipment. The air supplied to the clutch must be free of oil and moisture.
  • Page 74 It is essential when removing the gear reducer, to record the positions of these shims so that they may be replaced in the exact same position later. Bearing this in mind, carefully remove the gear reducer mount- ing bracket (with the reducer attached) from the drive base. Note that the clutch tire, attached to the reducer output shaft, must be allowed to slip out of the clutch drum as the reducer is removed.
  • Page 75 3. Temporarily disconnect the internal air line to the gear reducer and connect an external, valve-controlled air line to the reducer, but do not inflate the tire yet. 4. Loosen but do not remove the bolts that attach the gear reducer mounting brackets to the drive base. (On 64" machine models, check to be sure the jacking bolts under the input shaft side of the reducer are resting on the drive base then loosen the bolts and remove the dowel pins if they were reinstalled.) 5.
  • Page 76 To replace the jackshaft, reassemble all components in reverse order of their removal. Make certain that the jackshaft is properly oriented with the clutch end of the shaft to the front of the machine and that all shims are returned to their original positions. Install all jackshaft mounting bolts hand tight. Lift each end of the jackshaft with a pry bar (one end at a time) then tighten the bolts on that end, so that the jackshaft will sit as high as possible in the housing.

    Ê C entrifugal Switch Ë C oncept of Operation —After an extraction, the centrifugal switch will signal the Miltrol as soon as the washer cylinder has slowed sufficiently to permit the wash speed clutch to re-engage. Also, until this low speed has been attained, the Miltrol circuits prevent the opening of the shell door, thus providing safety interlocking.

The water, chemical, and steam valves close, the drain opens (ma- chines with normally open drain valves), and the shellfront tilts to the angle neces- sary for the correct adjustment of the accelerometer.

  • Page 125 The excursion switch actuator must be exactly in the center of the slotted hole - both when the machine is pushed down and when it is hanging free. If not, the switch will actuate prematurely (during the initial excursion at the onset of extraction), causing unnecessary recycles.
  • Page 126 Ê A djustments ® When the machine leaves Milnor , the actuator arm is tie-wrapped to prevent damage (except on 30015, 30020, and 30022 models). This tie wrap must be removed after the machine is set into position but before the machine is op- erated.
