Form No F030106A 15 Part No 840186 MV650H PUSH Vacuum Owner’s Manual VACUUMING OPERATION This machine is designed for vacuuming leaves, grass clippings, and other types of organic litter. Debris mixed with cans, bottles, and small amounts of sand can be vacuumed; however, it is not this machine's primary purpose. Vacuuming cans, bottles, and sand will affect the longevity of your machine. In dusty conditions it maybe necessary to purchase Felt Bag Kit (P/N 840022). Do not operate if excessive vibration occurs. If excessive vibration occurs, shut engine off immediately and check for damaged or worn impeller, loose impeller bolt, loose impeller key, loose engine or lodged foreign objects. Note: See parts list for proper impeller bolt torque specifications. (See trouble shooting section on page 22). SHUT DOWN 1. Pull Throttle Control all the way back to the STOP position. CLEARING A CLOGGED NOZZLE DISCONNECT spark plug wire before servicing unit. 1. Shut engine off and wait for impeller to stop completely. 2. Disconnect spark plug wire. 3. Wearing durable gloves, remove clog. WEAR durable gloves. Clog may contain sharp materials. 4. Reconnect spark plug wire. DEBRIS BAG Debris bags are normal replaceable wear items. Frequently empty debris to prevent bag overloading with more weight than you can lift. Bag liners are available for use in various conditions where debris will be vacuumed. (see Bag Liner Options shown on page 1). DO NOT place bag on or near hot surface, such as engine. Be sure engine has come to a complete stop before removing or emptying bag!!. This vacuum is designed for picking up trash, organic material and other similar debris (see Safety Warnings page 4-5). Many vacuums are used where dust is mixed with trash. Your unit can intermittently vacuum in dusty areas. However, following these rules will help maintain your machine's ability to vacuum in dusty conditions: •Run machine at idle to quarter throttle. •Machine or pressure-wash debris bag if normal cleaning does not fully clean bag. Bag should be thoroughly dry before use. Part No 840186 16 Form No F030106A MV650H PUSH Vacuum Owner’s Manual Having one or more spare bags (840189) is a g...
