OPERATION
VACUUMING OPERATION
VACUUM NOZZLE HEIGHT ADJUSTMENT:is raised and lowered by adjusting front wheel height control.
FOR MAXIMUM PICKUP: Adjust nozzle close to debris, but without blocking airflow into the nozzle. NOTE:
Never bury nozzle into debris.
CLEARING A CLOGGED NOZZLE & EXHAUST:Turn engine off and wait for impeller to stop completely
and disconnect spark plug wire. Wearing durable gloves, remove clog. Danger, the clog may contain sharp
materials. Reconnect spark plug wire.
DEBRIS BAG
Debris bags are normal replaceable wear items.
Note: Frequently empty debris to prevent bag overloading with more weight than you can lift.
An optional bag and dust cover is available for use where debris will be vacuumed in dusty conditions (see Optional
Accessories shown on page 1).
DO NOT place bag on or near hot surface, such as engine. Run engine at 1/2 throttle for first 1/2 hour to condition
new bag. Your new bag requires a break-in period to condition the pores of the material against premature blockage.
The entire bag surface serves as a filter, and must be able to breath to have good vacuum performance.
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 2 & 3).
However, many vacuums are used where dust is mixed with trash. Your unit can intermittently vacuum in dusty areas.
Dust is the greatest cause of lost vacuum performance. However, following these rules will help maintain your
machine's ability to vacuum in dusty conditions:
•Run machine at idle to quarter throttle.
•The debris bag must be cleaned more frequently. A vacuum with a clean, pillow soft bag will have good pickup
performance. One with a dirty, tight bag will have poor pickup performance. If dirty, empty debris and vigorously shake
bag free-of-dust.
•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 debris bags is a good way to reduce down time while dirty bags are being cleaned.
•DO NOT leave debris in bag while in storage.
COMPOST
Vacuumed leaves, grass and other organic material from your own yard can be emptied into a pile or composter to
provide enriched soil for later use as fertilizer in gardens and flower beds
NOTE: Allow green chips to dry before spreading around living plants.
