SERVICE AND MAINTENANCE WARNING: Maintenance and repairs must be done by authorized personnel only. Keep Adjustments according to specifications. WARNING: To prevent injury always stop the engine or motor before doing any maintenance or repairs to this machine. Separate the connectors between the machine and batteries. Disconnect the wire from the spark plug. How To Check the Engine 1. Check oil level regularly. Change oil after using first two tanks of gasoline.
Drive Belts WARNING: To prevent injury always stop the engine or motor before doing any maintenance or repairs to this machine. The drive belts are automatically tensioned by a springloaded idler wheel. (See Fig. 9) 1. 2. 3. 4. 5. Remove the idler pulley tension spring. Slip the belt off the pulley. Install a new belt. Assemble idler tension spring. Align pulleys and belts if necessary. Main Broom Adjustment The main broom should be periodically readjusted as needed to compensate for wear.
Installation of New Main Brush (cont) Remove the three screws and washers and the bristle strip retained by them. Install the new strip and assemble the retaining screws and washers. Be sure to install the "V" of each strip in the same relation to the core as its companion strips. (See Fig. 11, page 11) CAUTION: The strips must be carefully centered on the core before they are firmly locked into position.
Capacitor Test If a commercial capacitor checker is not available, the following test may be made: 1. Briefly short the capacitor terminals together with a screwdriver. 2. Disconnect a wire from either capacitor terminal. 3. Adjust an ohmmeter to a high value such as RX10K or RX1 Meg. 4. Connect the ohmmeter leads to the capacitor terminals. 5. A good capacitor will cause the indicator to move quickly to zero ohms, then slowly return to infinite ohms.
