Extension Cords
Make sure your electrical cord set is in
good condition and suitable for outdoor
use. When using an extension cord, be
sure to use one heavy enough to carry
the current your product will draw. An
undersized extension cord may cause a
drop in line voltage resulting in loss of
power and overheating. The table below
shows the correct size (AWG) to use for
your machine (Cord types SJW or
SJTW) depending on cord length and
nameplate ampere rating. If in doubt,
use the next heavier gauge. The smaller
the gauge number, the heavier the cord.

Vacuuming dry materials
WARNING
Flammable materials must not be
vacuumed.
Always make sure that the filter bag has
been fitted in the container before
vacuuming dry materials. The
vacuumed material can then be
disposed of without difficulty. Dry
materials can also be vacuumed without
filter bag.
NOTICE
Never use the vacuum cleaner with a
damaged filter element or without the
filter element.
Vacuuming liquids
WARNING
Flammable liquids must not be
vacuumed.
Always remove the filter bag and check
operation of the float before vacuuming
liquids. The float switches off the air
stream when the container is full. If the
machine is exclusively used for wet-
vacuuming, the filter element should be
replaced by a special insert (special
accessory).
The filter element is damp after
vacuuming liquids. The filter element is
likely to clog up more quickly if dry
material is vacuumed while it is still
damp. For this reason, the filter element
should be dried or replaced by a dry filter
element before vacuuming dry
materials.
NTurn the master switch to 0
