By pulling this lever to the right slightly or start position the belts are loosened enabling the engine to be started without anyoperating load. Put lever #78 in down position.3. Close choke completely and pull starter rope once. Open choke slightly and pull rope again. When engine starts,gradually open choke until completely open.4. With engine running, push sickle bar lever #52 towards center of unit or run position. By pulling back and up on lever #78,your unit is self-propelled.USE OF LEVERS1.CAUTION: The sickle bar handle lever is designed as an aid to easy starting and possibly an emergency. Do not engageor disengage either of the levers and attempt to remove debris from any part of the unit – STOP THE ENGINE to removedebris.2.When the mower is operating, disengaging either lever will stop forward motion. Disengaging sickle bar lever will stop boththe sickle bar and forward motion.3.Never allow engine to operate with sickle bar lever disengaged for long. Engine pulley will build up heat in belt and destroyit.4.When operating mower, set throttle where required (see mowing tips), leave sickle bar lever engaged and useself-propelled lever to start, stop and turn or maneuver. You can, but it is not necessary to adjust throttle.BELT TIGHTENING1. Power unit belt #34 (longest belt of 3) has automatic spring tension and requires no tightening.2. Dual pulley belt #62 (next longest belt) is tightened by first loosening the engine mounting bolts #97, and placing thesickle bar lever #52 in the run position and then, turning the bottom nut #54 clockwise after loosening top nut #54. Do notover tighten belt – allow a slight slack. A slight slack can be checked by grasping one side of the belt in the middle betweenthe pulleys with the thumb and forefinger and attempting to move belt from left to right and right to left. If belt feels taut orsimilar to a bowstring, it is too tight. Leave bolts #97 loose.3. To tighten engine pulley belt #63 (smallest belt), leave sickle bar lever in run position, push down on right side of engineuntil engine pulley belt is as tight as dual pulley belt and then tighten bolts #97.4. To further check for belt tightness, listen for a squealing noise when cutting under average conditions – it most likelyindicates the belts are too loose. Belts should squeal or smoke when hard objects such as stones or possibly a hard woodsapling encountered in the sickle bar (see mowing tips). Recognize that an improperly adjusted sickle bar could alsocause properly adjusted belts to squeal (see sickle bar adjustments). In any event, once you are satisfied, the belts are tooloose; you can refine your belt adjustments with the following procedure. Place the sickle bar lever in the start or slightly rightposition and leave it in this position, loosen top nut #54, start engine and turn bottom nut #54 clockwise until knife assemblyin sickle bar starts to creep. When creeping point reached, turn nut counterclockwise until creeping stops and wait a fewminutes to see if creeping starts again. If it does, turn nut counterclockwise until creeping stops completely.Stop engine, place sickle bar lever in the run position and feel belts for tightness as described. If they appear too tightslightly turn bottom nut counterclockwise until you being to feel a slight slack in belt. Retighten top nut against bottom nut.BELT REPLACEMENT1. To replace engine pulley belt #63 and dual pulley belt #62 put sickle bar lever #52 in the start position and turn old beltoff dual pulley #59.2. To replace power unit belt #34 remove fender #91 and belts #62 and #63. Remove left drive pinion #40 and slide lowercontrol rod #42 out of the bracket assembly #36. The lower idler assembly arm #28 has a hole in its most forward point.Insert a screwdriver in the hole and pry up to remove belt from lower idler pulley #30 to obtain sufficient slack for beltremoval. Install new belt by placing it in the smaller pulley of the twin pulley #23 and slip the outer end of the belt over thepower unit shaft #35 (not pulley). Next, place belt in the flat groove on the top of bottom idler pulley #30 by giving the belta ¼ twist so that the backside of belts rests in the flat groove. Insert V groove on top of upper idler pulley #33. Place belt inpower unit pulley last by placing screwdriver in hole of idler arm again to obtain sufficient slack.SPEEDSee speed information under mowing tips also. If your Monarch is equipped with a 4” O.D. engine pulley used for generalpurpose mowing and you find the unit moves too fast for your mowing conditions, you can purchase locally a 3” O.D. agroove engine pulley of equal grade along with a 29” A groove belt to slow the unit down. Manufactures code # for belts isA-27. For assistance in purchasing, contact dealer where you purchased unit or a local hardware or automotive store.MOWING TIPS1. The secret to good cutting lies in sickle bar adjustment. A well-adjusted sickle bar sounds similar to a sewing machine.One that is too loose or too tight clatters. When machine is new, paint may cause binding in the area where knife clips#125 contact knife assembly #124. Put oil in this area before starting machine. After a few minutes of operation, recheckadjustments as shown in sickle bar diagram. |
