EVERY 250 HOURS SERVICE c. AIR CONDITIONER COMPRESSOR BELT 1. The belt tension should normally deflect by about 10 mm when pressed with the finger at a point midway between the air condi- tioner compressor pulley and the drive pulley (approx. 6 kg). 2. To adjust the belt tension, loosen bolts (I) and lock nut (31, and rotate adjusting bolt (2). 3. After adjustment, tighten bolts (1) and lock nut (3) securely. * After operating the machine for one hour with a newly exchanged V-belt, test and adjust the V-belt again. * When adjusting the V-belt, do not attempt to push the compres- sor directly with a bar or the like, but use a wood pad to prevent damage to the core.
t Check each pulley for damage, and V-grooves and V-belt for wear. Particularly, check whether V-belt is in contact with bottom of V-groove through wear. * Replace belt if it has stretched, leaving no allowance for adjustment, or if there is a cut or crack on belt. W-02073 - 85 -
