WARNING – Never start up the blower
if the safety guard (G, Fig.10) is open,
damaged or cannot be closed properly,
except when the vacuum tube is fitted.
WARNING – Always check that the bag
is intact and that the zip is fastened,
before starting the machine. Never use
the machine with a damaged bag. Risk of
injury caused by flying debris.
WARNING – Avoid any direct contact of
body parts with the exhaust outlet of the
muffler.
USE
WARNING – Always take hold of the
machine firmly with both hands.
The vacuum is designed to be held in both
hands (Fig. 22), with the right hand on the
control grip and the left hand on the grip on the
housing . This applies for right-handed and left-
handed users alike.
Sling the collection bag over the right shoulder
and insert the left arm. The collection bag must
always be fitted when the machine is used as a
vacuum.
The large diameter vacuum tube is able to
pick up large leaves, as well as fragments of
cardboard and tree bark.
Take care not to vacuum up larger objects
(wood, tin cans, lengths of string or tape) that
could obstruct or damage the blades of the
impeller.
Take care when vacuuming wet leaves, as
these could clog the impeller.
Take care not to block the vacuum tube as this
could result in over-revving and damage the
engine.
CAUTION – Do not drag the end of the
vacuum tube along the ground.
CAUTION – Do not vacuum up abrasive
materials, such as sand or gravel, that
could swiftly degrade the impeller.
WARNING – Never vacuum up hot or
burning substances, or liquid fuels. Do not

use the vacuum for inflammable liquids
or toxic substances (e.g. fuel) or even
materials that are impregnated with such
substances. This could cause fatal burns
or explosion!
CAUTION – When vacuuming, abnormal
noises or fluctuations in engine rpm
could indicate a blockage internally
of the machine. Switch off the engine
immediately, disconnect the vacuum tube
and check whether or not the internal
ducts are obstructed by debris.
MAINTENANCE
IMPELLER HOUSING – Periodically clean the
inside of the impeller housing to remove dirt
and debris that could otherwise impair the
performance of the machine.
IMPELLER – Check that the blades are clean
and undamaged to prevent reduced air flow
and increased vibration. If the impeller blades
are damaged, contact your authorised service
centre immediately.
COL LEC TION BAG - M u s t b e w a s h e d
periodically to maintain good suction and
filling. Check the integrity of the bag and make
