WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1, along with hearing protection.
Failure to do so could result in objects being thrown into
your eyes and other possible serious injuries.
WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in
serious personal injury or property damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
OPERATION
 Place the vacuum bag strap over your right shoulder.
Hold the upper handle in your left hand and the vacuum
handle in your right hand.
 Move the blower/vacuum from side to side along outer
edge of the debris. To avoid clogging, do not place the
vacuum tube directly into the debris pile.
 Hold the engine higher than the inlet end of the vacuum
tube.
 Always point vacuum tube downhill when working on a
hillside.
 To avoid serious injury to the operator or damage to the
unit, do not pick up rocks, metal, broken glass, bottles,
or other similar objects.
 If the vacuum tubes should clog, stop the engine , ensure
impeller blades have stopped spinning, and disconnect
the spark plug wire before cleaning out the obstruction.
 Remove the vacuum tubes and clear the debris from the
blower fan housing. Remove the bag and clear the tube.
A small rod or stick may be required to clear the entire
tube length. Ensure that all debris has been cleared before
reassembling the vacuum tubes.
MAINTENANCE
You can often make adjustments and repairs described here.
For other repairs, have the blower/vacuum serviced by an
authorized service dealer.
CLEANING THE AIR FILTER
See Figure 13 - 14.
For proper performance and long life, keep air filter clean.

Remove the air filter cover by turning the dial counter-
clockwise while gently pulling on the cover.
 Rinse filter with clean water.
 Gently squeeze filter until excess water is removed.
Replace filter.
 Place the air filter cover back on the unit. Turn dial clock-
wise until cover is secure.
CLEANING THE EXHAUST PORT, MUFFLER
AND SPARK ARRESTOR
NOTE: Depending on the type of fuel used, the type and
amount of lubricant used, and/or your operating conditions, the
exhaust port, muffler, and/or spark arrestor screen may be-
come blocked with carbon deposits. If you notice a power
loss with your gas powered tool, you may need to remove
these deposits to restore performance. We highly recom-
mend that only qualified service technicians perform this
service.
The spark arrestor must be cleaned or replaced every 50
hours or yearly to ensure proper performance of your prod-
uct. Spark arrestors may be in different locations depending
on the model purchased. Please contact your nearest service
dealer for the location of the spark arrestor for your model.
WARNING:
Never run the blower without the spark arrestor in place.
Failure to do so could result in a fire that could cause
serious personal injury.
