VACUUMING OPERATION
This machine is designed for vacuuming leaves, gras s 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 23).
1. Move Shift Lever to correct position (1, 2, or 3) for desired gear.

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.
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.
Having one or more spare Felt Filter (840194) is a good way to reduce down time while dirty bags are being
cleaned.
Be sure engine has come to a complete stop before removing or emptying bag!!.

HANDLING and TRANSPORTING
Using two people to lift unit is recommended. Lift holding the handle and front of nozzle. Make sure equipment is
properly secured before transporting. See MV650 series specifications on page 3 for unit weight.
NEVER lift the machine while the engine is running.
STORAGE
DO NOT store engine in an enclosed or poorly ventilated area where fuel fumes may
reach an open flame or spark from a furnace, water heater, clothes dryer or similar
devices.
DO NOT drain fuel in an enclosed or poorly ventilated area.
DO NOT smoke when draining fuel.
DO NOT remove gas cap while engine is running.
DO NOT park equipment on a steep grade or slope.
ALWAYS remove spark plug wire when servicing equipment to prevent accidental
starting.
ALWAYS keep hands and feet away from moving or rotating parts.
ALWAYS store fuel in approved safety containers.
If the equipment will not be used for 30 days or more, prepare as follows:
1. Make sure engine is cool.
2. Drain gasoline from carburetor and fuel tank to prevent formation of gum deposits.
3. Run engine until tank is empty and engine runs out of gas.
Fuel stabilizer (such as Sta-Bil
gum deposits during storage. Add stabilizer to gasoline in storage container or fuel tank. Follow
TM
) is an acceptable alternative for minimizing the formation of
stabilizer manufacturer’s instructions to determine proper mix ratio. Run engine at least 10
minutes after adding stabilizer to allow it to reach carburetor.

IMPELLER REMOVAL
READ all safety instructions before servicing unit.
MV650SPH Self-Propelled Vacuum Owner’s Manual
DISCONNECT spark plug wire before servicing unit.
Tools required:
- 1/2” socket, 3/8” drive
- ratchet, 3/8”
- drive extension, 3/8” drive
- universal joint, 3/8” drive
- pry bar or long screwdriver
- jack stands or similar device adequate to support weight of machine.
1. Wait for engine to cool and disconnect spark plug.
2. Drain fuel and oil from the engine.
3. Remove belt cover by removing 5 screws.
4. Detach drive belt from the transmission pulley by rotating the transmission assembly to relieve belt tension.
5. Remove engine, impeller and mounting plate by removing bolts around outside of housing.
6. Leaving engine fastened to plate, remove impeller bolt and lock washer and slide impeller off crankshaft ( A
puller may be required). CAUTION: Do not drop impeller.
7. If impeller does not slide off crankshaft, place two crowbars between impeller and housing on opposite
sides. Pry impeller away from engine until it loosens. Using a penetrating oil can help loosen a stuck
impeller.
8. If the impeller cannot be loosened, obtain a 1” (25.4mm) longer bolt of the same diameter and thread type as
the impeller bolt. Invert engine and impeller and support engine above ground to prevent recoil damage.
Thread longer bolt by hand into the crankshaft until bolt bottoms. Using a suitable gear or wheel puller
against the bolt head and the impeller back-plate (near the blades), remove impeller from shaft.
9. To reinstall impeller, use a new impeller bolt and lockwasher
10. Tighten impeller bolt. Torque impeller bolt to 50 Ft. Lbs. (68 N.m).
11. Reinstall engine, impeller, and mounting plate onto housing in reverse order of removal.
12. Before connecting spark plug wire, slowly pull engine starting rope to insure that impeller rotates freely.
13. Reconnect spark plug wire.

INSTALLING NEW DRIVE CHAIN/ALIGNMENT/TENSION
READ all safety instructions before servicing unit.
DISCONNECT spark plug wire before servicing unit.
Tools required:
- 3/8” drive ratchet with 8” or longer extension.
- 3/8” socket wrench.
- 7/16” and 1/2” socket.
- 7/16” and 1/2” combination wrench.
- “Needle nose” pliers
- Flat head screwdriver
Allow the engine to cool completely and DISCONNECT THE SPARK PLUG.
1. Unfasten and remove the guard.
2. Rotate left rear wheel to bring the chain “master link” into view on the axle
sprocket.
3. Using the needle nose pliers carefully remove master link retaining spring
clip.
4. Slide the master link from the chain and remove the chain.
5. Thread the new chain onto the sprockets, place the ends of the chain on the
axle sprocket, this makes it easier to hold the chain in place when you slide
the new master link in place.
6. Install the new master link and CAREFULLY install the retaining clip.
7. Rotate left rear wheel to find the location where the chain is tightest (there
are always slight variations in the sprockets that make the chain tighter at
places in its rotation).
8. Rotate the axle several times and listen for “popping” or “clacking” this
indicates too much tension on the chain or misalignment of the chain. Skip
to Step 12 if no “popping” or “crackling” occurs.
Improper Chain Tension
9. At the point where the chain is tightest check the chain to for ¼” to ½” total
slack halfway between the axle sprocket and the transmission sprocket.
Skip to Step 11 if the deflection is correct.
10. Loosen 4 nuts holding the bearing bracket (see Fig 1) slide it very slightly
forward to tighten the chain or slide backward to loosen. Tighten 4 nuts
back then check the chain deflection. Repeat this step if necessary.
Improper Chain Alignment
11. Loosen 5 bolts securing the drive system (see Fig 2) slide it left or right
then check the alignment using straight edge. Tighten 5 bolts then repeat
Step 8.
12. Reinstall the guard and all of its fasteners.
13. RECONNECT THE SPARK PLUG.
