Pull recoil with a quick firm pull. Do not pull out so far that rope stops with a jerk as this will cause rope failure. Do not allow rope and handle to snap back into place. 2 4. After two or three full firm pulls on recoil (or as soon as engine fires), move throttle control to run position. 5. Operate a new engine at intermediate speeds and light load for the first few hours as you would a new automotive engine. 6. To stop engine, move throttle control lever on handle to stop position. 7. If carburetor needs adjustment to start or for operation, see "carburetor readjustment" section. 8. For forward travel, move drive engagement lever FORWARD as far as possible. To stop forward movement, pull lever towards the operator into neutral position. NOTE: A brief break-in period is essential to insure maximum engine life. This consists of running the engine at half-speed for a period of time required to use one tank of gasoline. This is necessary on the initial run only. It is also recommended that the oil be changed after five (5) hours of operation. This allows for the removal of impurities which may have accumulated during the break-in period. Subsequent oil changes should be made as stated in the engine manual. Always check oil before using your vacuum. Be sure crankcase is full. ADJUSTMENTS CAUTION: Do not at any time make any adjustment to power vacuum without first stopping engine and disconnecting spark plug wire. 1. NOZZLE GROUND CLEARANCE—Th is vacuum can be adjusted for nine heights from 0" to 5". To change the height, move the height adjustment lever towards the engine and forward to raise the height and move to the rear to lower the height. The one lever adjusts the front two wheels at the same time. 2. BELT—The belt requires no adjustment. The idler maintains the proper tension on the belt at all times. 3. THROTTLE—Self propelled unit only. If adjustment becomes necessary, the throttle control wire assembly can be reset as follows: a. Loosen, but do not remove, screw securing throttle control wire assembly at engine. b. Move throttle control lever on handle to "Fast" position. c. Move lever to which control wire is fastened at engine, to full open position and retighten screw to secure throttle control wire assembly.
