MAINTENANCE (summary)
See the ATTACHED SHEET for full details.
PURPOSE is to maintain the smooth running, load-bearing capacity and safety of the installation
PURPOSE
by means of:
PURPOSE
- careful handling, - constant care, - necessary maintenance
MEASURES
- perform a VISUAL INSPECTION before and after use.
-
Damaged stands must not be used or only after qualified repair.
- Care and maintenance work must always be carried out in an unloaded condition
- There may be hidden hazards, such as bruising when folding the feet,
-
in order to avoid these, it is necessary to handle with care.
-
If necessary, use protective gloves.
- For cleaning use a slightly damp cloth and a non-abrasive cleaning agent
- Other measures such as periodic lubrication etc. are not necessary.
ATTACHING and EXTENDING THE LOAD
EXTENSION TUBE: ø 35 mm, movement 894 mm (= 6 x 149 mm)
5
The extension tube has a light-grey conical spigot, the so-called
5
mounting aid, which makes it easier to find the speaker and facilitates
5
the fitting of the speaker.
5
See K&M accessories: 19654, 19456, 24281, 19580
WARNING!
Do not underestimate the weight of the speaker:
- When placing the speaker and extending or retracting the tube, be sure
-
to employ technically and physically suitable personnel.
- Hold the extension tube with a firm grip during height adjustment
6
-
and always secure the chosen final position with the locking pin
10
.
MOVING THE LOAD
Involved parties:
FIRST PERSON: (in case of heavy loads, several persons if necessary):
FIRST PERSON:
- operates the extension tube with the load
6
,
11
SECOND PERSON: - attends to the clamp
SECOND PERSON:
a. the clamping screw
7
,
13
and
SECOND PERSON:
b. the locking pin
8
,
10
,
12
ATTENTION!
If FIRST PERSON can no longer hold securely the loaded extension
tube, then the SECOND PERSON should:
a. immediately tighten the clamping screw
13
,
b. releases the locking bolt
10
and ensure that the bolt engages
b.
automatically in the nearest borehole.
EXTENDING THE LOAD
FIRST PERSON
6
holds the loaded extension tube tightly with both hands.
6
Does not cover the boreholes.
SECOND PERSON
7
loosens the clamping screw and holds it
8
then presses the push button until the locking pin
8
no longer engaged in the extension tube
FIRST PERSON
9
lifts the extension tube together with the load
9
into the approximately chosen height;
9
NOTE:
9
In order to find the chosen borehole easily, the bore should find itself
9
in this very moment just above the clamp
SECOND PERSON
10
releases the push button, so that the locking pin
10
automatically snaps into the extension tube.
FIRST PERSON
11
lowers the extension tube slowly until the locking pin
11
engages in the intended hole
SECOND PERSON
12
ensures that the locking pin is engaged as far as it goes
12
(= no protrusion is allowed)
13
tightens the clamping screw
RETRACTING THE LOAD
FIRST PERSON
6
holds the loaded extension tube with both hands,
6
without covering the boreholes.
SECOND PERSON
7
loosens slightly the clamping screw and...
8
...pushes the button and holds it
8
(the locking bolt is unlocked)
FIRST PERSON
11
lowers the extension tube slowly and controlled
SECOND PERSON
13
measures the clamp force of the screw so that the extension tube,
13
due to the friction in the clamp, retracts slowly and not suddenly
13
and uncontrolled
FIRST PERSON
11
whilst still holding the extension tube tightly, to ensure the controlled
11
retracting of the load. This needs to be carried out until the desired
11
height is reached or until the tube is completely retracted.
SECOND PERSON
10
releases the push button, so that the latching pin will automatically
10
snap into the extension tube
12
ensures that locking bolts engaged as far as it will go
12
(= no protrusion allowed)
13
tightens the clamping screw
