ADJUSTING HOSE BOOM
Properly adjusting the boom will prevent most hose clogs from occurring and will
maximize vacuum performance by keeping the hose straight and perpendicular
to the housing (see fig. 5). Height adjustments are made by raising or lowering
one of the attachment links to a different area on the chain.
VACUUMING OPERATION
EXHAUST DIRECTION & DISTANCE:
Exhaust direction and distance are controlled by
the rotation of the exhaust elbow. Typically debris is aimed to discharge to the rear of the
container. The direction of discharge is adjusted by turning the crank on the exhaust
elbow clamp and rotating the elbow to the desired direction.
NOTE:
Elbow is heavy. Use caution when adjusting. Never stand directly under the elbow
while adjusting direction of exhaust.
Never direct exhaust into an area where bystanders may cross the path of the
debris.
INTAKE OPERATION:
With machine running and fully assembled, move the nozzle in
sweeping motions over debris. Always allow air to flow into the nozzle along with the
debris. Do not completely block the nozzle when vacuuming, it will reduce performance,
and increase clogging (See figure 3).
For removal of heavier debris, or debris that is stuck to the ground, rock nozzle forward to
concentrate suction power around the debris (See figure 4).
UNCLOGGING A CLOGGED HOSE
With engine running and unit secured to a trailer, truck bed, or other similar surface,
fully stretch hose in a straight line to dislodge the clog. If the clog will not clear, turn unit
off, and allow engine to come to a complete stop. Remove hose and manually clear
hose clog.
NOTE:
The clogged debris may be sharp. Always wear durable gloves when
removing clog.
UNCLOGGING A CLOGGED HOUSING OR EXHAUST ELBOW
Turn engine off and wait for impeller to come to a complete stop. Disconnect spark plug
wires and battery cables. Remove the hose from the housing and determine where the
clog is located. If possible clear the clog through the intake opening. It may require
removal of the intake adaptor (item 33) to allow access to clear the housing. If clog is in
the elbow, carefully remove the elbow. Remove elbow by removing the bolts and nuts
on the elbow clamp so that the plates can be removed.
NOTE:
Elbow is very heavy. Do not stand directly under elbow during removal.
Danger
, the clog may contain sharp materials. Wearing durable gloves, clear the clog.
Reconnect spark plug wire.
HOSE CARE AND TIPS
To increase hose life, periodically rotate hose and reposition nozzle and coupler on
front plate of unit. This increases hose life by keeping hose from wearing only on one
side.
Keep hose as straight as possible and avoid sharp bends during operation for best pick-
up and to avoid clogs.
Never drag hose. Always remove and store hose before transporting unit.
Store hose straight and flat to maintain flexibility for next use.
THE HOSE IS A REPLACEABLE WEAR ITEM.
STORAGE
Turn fuel supply off when unit is not in use. Never store engine indoors or in enclosed poorly ventilated areas with fuel in tank, where
fuel fumes may reach an open flame, spark or pilot light, as on a furnace, water heater, clothes dryer or other gas appliance.
If engine is to be unused for 30 days or more, prepare as follows:
Be sure engine is cool. Do not smoke. Remove all gasoline from carburetor and fuel tank to prevent gum deposits from forming on
these parts and causing possible malfunction of engine. Drain fuel outdoors, into an approved container, away from open flame. Run
engine until fuel tank is empty and engine runs out of gasoline.
NOTE:
Fuel stabilizer (such as Sta-Bil) is an acceptable alternative in
minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always
follow mix ratio found on stabilizer container. Run engine at least 10 min. after adding stabilizer to allow it to reach the carburetor.
HOSE STORAGE: Storing hose in a covered area, out of sunlight and heat will prolong hose life. Do not store hose where it could
be stepped on or where other objects could crush or damage hose.
