AIR VENTS
Never cover air vents. Keep them free from obstructions
and debris. They must always remain clear for proper
motor cooling.
WARNING:
To avoid serious personal injury, do not
wear loose fitting clothing or articles such as scarves,
strings, chains, ties, etc., that could get drawn into the air
vents. To make sure long hair does not get drawn into the
air vents, tie back long hair.
OPERATING AS A BLOWER
Hold the blower firmly. Sweep from side to side with the
nozzle several inches above the ground or floor. Slowly
advance the unit, keeping the accumulated pile of debris in
front of you. Most dry blowing operations are better suited
to low speeds, rather than high. High speed blowing is a
better way to move heavier items like large debris or
gravel.
OPERATING AS A MULCHER
Hold the vac firmly, tilting the mulcher tubes (2-4 in. or
5-10 cm), and use a sweeping action to collect light debris.
SERVICING DOUBLE-INSULATED UNITS
This unit is double insulated. In a double-insulated unit,
two systems of insulation are provided instead of ground-
ing. There is no grounding provided and no means of
grounding should be added to this unit. Extreme care and
knowledge of the system is required when servicing a
double-insulated unit. Service should be performed by
qualified service personnel only. Replacement parts for a
double-insulated unit must be identical to the parts they
replace. Refer any repairs to an authorized service dealer.
A double-insulated unit is marked with the words "double
insulation" or "double insulated."
CLEANING THE UNIT
WARNING:
To avoid serious personal injury,
always turn the unit off and unplug it before cleaning or
servicing. Use a small brush to clean off the outside of the
unit. Do not use strong detergents, household cleaners
that contain aromatic oils such as pine and lemon, and
solvents such as kerosene as they can damage plastic
housings or handles. Wipe off any moisture with a soft, dry
cloth.
OPERATION
The debris will flow into the bag. Items such as small
leaves and twigs will be mulched as they pass through
the fan housing. For longer bag life and increased
performance, empty the bag often.
CLEARING A BLOCKED TUBE / IMPELLER
WARNING:
sure the unit is OFF and unplugged before clearing the
impeller.
WARNING:
wear gloves to protect yourself from the impeller blades or
other sharp objects.
1. Slide the Power/Speed switch down to the OFF position
until the unit comes to a complete stop.
2. Unplug the unit.
3. Remove the blower tube or mulcher tubes and the bag.
4. Carefully remove material blocking the tube or impeller.
Inspect the blades to ensure no damage has occurred.
Rotate the impeller blades by hand to ensure the blockage
is completely cleared.
5. Reinstall the blower tube or mulcher tubes and the bag.
6. Plug the unit back into the power supply.

MAINTENANCE

CLEANING THE BAG
1. Empty the bag after each use to avoid deterioration and
obstructing air flow, which will reduce the performance of

and vigorously shake out dust and debris.
3. Wash the bag once a year, or more often if needed:
