N Mount suction tube holder at a 
distance (A) of approx. 8 inches 
(20 cm) from the bottom edge of the 
extension tube
N Depending on the intended use of 
the vacuum, fit the crevice tool (5), 
all-purpose tool (6) or floor tool (7) 
onto the suction tube.
The voltage and frequency of your 
power supply and the voltage and 
frequency specified on the unit must be 
the same.
The connection to the power supply 
must be protected by a fuse or a circuit 
breaker with a minimum rating in 
accordance with the specifications ā see 
"Specifications."
The power tool must be connected to the 
power supply via a Ground Fault Circuit 
Interrupter (GFCI). Receptacles are 
available having built-in GFCI protection 
and may be used for this measure of 
safety.
The electrical power supply connection 
must comply with all applicable 
standards and regulations.
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.
Appropriate extension cords are 
available in special stores for electrical 
equipment or from your STIHL dealer.
Connection to the power supply socket
Before connection to the power supply, 
check that the machine is switched off ā 
see "Switching off the machine"

cord into a properly installed outlet
