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.
Having one or more spare Felt Filter (840194) is a good way to reduce down time while dirty bags are being
cleaned.

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 33-38 Ft. Lbs. (45-52 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.
DRIVE CLUTCH CABLE ADJUSTMENT
READ all safety instructions before servicing unit.
DISCONNECT spark plug wire before servicing unit.
Tools required:

Procedure:
1. Wait for engine to cool and DISCONNECT SPARK PLUG!
2. Engage the clutch lever then pull the unit back until it stops freewheeling. The clutch lever should engage

4. Holding the adjuster nut in place with one wrench tighten cable lock nut firmly.
5. Readjust as needed.
6. RECONNECT SPARK PLUG!
7. Test run unit to insure proper operation after this or any other maintenance procedure.
8. If clutch still will not engage at 4” from handle, remove guard retaining screws and guard.
9. Measure the amount of spring stretch. Spring should measure 1 1/8” when engaged (Lever 4” from handle).
10. Release clutch lever and then move it to engagement position again and hold it, check the spring length to
assure it stayed in adjustment.
11.Re-install guard and fasteners.
DRIVE BELT REMOVAL AND REPLACEMENT
READ all safety instructions before servicing unit.
DISCONNECT spark plug wire before servicing unit.
Tools required:

INSTALLING NEW DRIVE CHAIN/ALIGNMENT/TENSION
READ all safety instructions before servicing unit.
DISCONNECT spark plug wire before servicing unit.
Tools required:
-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.

Battery Care (For Electric-Starting Models)
Proper care can extend the life of a battery. Follow these recommendations to ensure your battery’s best
performance and long life:
• Do not allow the battery charge to get too low. If the machine is not used, charge the battery every 4 –6
weeks. Operate the engine for at least 45 minutes to maintain proper battery charge.
• Store an unused battery in a dry area that does not freeze.
• Do not charge an already charged battery. In theory, you cannot overcharge our battery with a trickle
charger; however, when a battery is fully charged and the charger is still on, it generates heat that could
be harmful to the battery. A fully charged battery will read 12V-13.2V with a voltmeter.
• Do not continue to crank your engine when the battery charge is low.
Charging the Battery
Operate the engine for at least 45 minutes to maintain proper battery charge. If the battery loses its
charge, you will need to use a trickle charger to recharge it. Caution: The charger should have an output
of 12 volts at no more than 2 amps. Using a charger with higher amps will cause significant damage to the
battery.
• At 1 amp, the battery may need charging for as long as 48 hours.
• At 2 amps, the battery may need charging for as long as 24 hours.
NOTE: Using the Recoil Starter and then running the engine will not recharge a dead or significantly
discharged battery.
WHEN YOU ARE FINISHED CHARGING THE BATTERY, DISCONNECT THE CHARGER FROM THE
OUTLET FIRST, THEN DISCONNECT THE BATTERY CHARGER WIRES FROM THE BATTERY. IF
YOU LEAVE THE BATTERY CHARGER WIRES CONNECTED TO THE BATTERY, THE BATTERY
WILL DISCHARGE ITSELF BACK INTO THE CHARGER.
