OPERATION TO START ENGINE (See Fig. 7) When starting engine for the first time or if engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine. Depress the clutch/brake pedal and set the parking brake Place motion control lever in "NEUTRAL" position. Move attachment clutch to "DISENGAGED" position. Move throttle control lever to "CHOKE" position for cold engine start. For warm engine start, move throttle control to "FAST" position. Turn ignition key clockwise to "START" position and release key as soon as engine starts Do not run starter continuously for more than fifteen seconds per minute. If engine does not start after several attempts, move throttle control to "FAST" position, wait a few minutes and try again When engine starts, slowly move throttle control lever to desired running speed. Al!ow engine to warm up for a few minutes before engaging motion control or attachment clutch NOTE: If at a high altitude (above 3000 feet) or in cold temperatures (below 32 Â° F), the carburetor fuel mixture may need to be adjusted for best engine performance. See "TO ADJUST CARBURETOR" in the Service and Adjust- ments section of this manual MOWING TIPS Tire chains cannot be used when the mower housing is attached to unit. Mower should be properly leveled for best mowing performance See "TO LEVEL MOWER HOUSING" in the Service and Adjustments section of this manual Use the runner on the right hand side of mower as a guide. The blade cuts approximately an inch outside the runner (See Fig 8). The !eft hand side of mower should be used for trim- ming Drive so that clippings are discharged onto the area that has been cut. Have the cut area to the right of the machine This will result in a more even distribution of clippings and more uniform cutting When mowing large areas, start by turning to the right so that clippings will discharge away from shrubs, fences, driveways, etc After one or two rounds, mow in the opposite direction making left hand turns until finished (See Fig 9) FIG, 9 If grass is extremely tall, it should be mowed twice to reduce load and possible fire hazard from dried clip- pings. Make first cut relatively high the second to the des red he ght Do not mow grass when it is wet. Wet grass will plug mower and leave undesirable clumps. Allow grass to dry before mowing Always operate engine at full throttle when mowing to assure better mowing performance and proper dis- charge of material Regulate ground speed by select- ing a low enough speed to give the mower cutting performance as well as the quality of cut desired When operating attachments, select a ground speed that will suit the terrain and give best performance of the attachment being used 13
