3 Locate the nozzle of the flexible hose on the ex-
haust pipe. Fasten the magnetic unit onto the an-
chor plate located on the side of the vehicle, see
Figure 11 .
4 Reverse the vehicle into its parking space.
5.2 Disconnection
1 Make sure the hose is connected to the exhaust
pipe and that it is firmly fastened to the anchor
plate on the vehicle’s side.
2 Start the fan and open the station door. Drive the
vehicle straight out from the garage with a maxim-
um speed of 5 km/h (3 mph). The hose automatic-
ally disconnects when the vehicle is driven out.
If the magnet does not disconnect as it should, it will
be pulled off the anchor plate by the hose without
damage to the system. This may cause the nozzle to
sway more than normally. Approx. 500 N (176 lbs) is
required to pull the magnet off the anchor plate.
A manual disconnection from the anchor plate is pos-
sible by lifting the handle of the magnet assembly up-
wards.
6 Maintenance
WARNING! Risk of personal injury
A dust filter mask should be used during ser-
vice and repairs inside the system, especially
when working on the nozzle and hose.
NOTE!
The service intervals in this chapter are based
on the unit being professionally maintained.
6.1 Check points
See Section 3.1 Main parts .
6.1.1 Check these points when needed and
at least twice a year
• The nozzle's internal contact surface. Clean with a
dry cloth when necessary.
• The magnetic operation. Check the attachment with
the connector and use a dry cloth to clean the mag-
net and anchor plate on the vehicle when necessary.
Tighten the center screw on the anchor plate.
• Disconnection position. The extraction hose should
disconnect from the exhaust pipe immediately be-
fore the station door opening at normal speed, not
more than 5 km/h (3 mph).
• Check the disconnection wire length and wire locks.
Check that the spring of disconnection wire is in-
tact and hocked on. Adjust when needed, see
Sec-
tion 4.6 Adjustment of disconnection wires .
• The operation of the balancer, make sure that the
hose lifts up properly. If necessary, adjust the lifting
power of the balancer. See
Section 6.1.2 Balancer .
• The cord on the balancer.
• Check that the trolley moves easily in the whole
length of the rail.
• Check the mounting brackets.
• The hoses.
6.1.2 Balancer
Maintenance and inspection
The balancer is designed to require little maintenance.
Periodically check cord and hanger for wear. The bal-
ancer is lubricated for life and requires no additional
lubrication. See
Figure 14 .
NOTE!
When changing the cord, the balancer must
first be removed from its support device and all
its spring tension must be released.
WARNING! Risk of personal injury
• Never overtighten the spring so the end posi-
tion can be reached.
• Never remove the spring from the drum and
spring assembly. Replacement springs are
sealed for safety.
Increasing spring tension
NOTE!
Do not overtighten the balancer! Use just
enough tension so it will retract the hose.
• Turn the mainshaft (1) with a wrench in a counter-
clockwise direction. Turn mainshaft 1/4 turn (1-
click) at a time until desired tension is achieved.
Decreasing spring tension
1 Turn the mainshaft (1) with a wrench in a counter-
clockwise direction just enough to release tension
lock lever (2).
2 Push tension lock lever (2).
3 Slowly allow mainshaft to turn clockwise and re-
lease tension lock lever before allowing mainshaft
to rotate 1/4 turn (1-click).
4 Repeat this process until desired tension is
achieved.
5 If the spring tension has been increased check
that the required length of the cable can be drawn
out without stretching the spring to the limit.
