COMPLETE VERSION of the relevant instruction summary
SAFETY INSTRUCTIONS
Numbers marked with *, e.g. *14, refer to reference numbers in the diagram of the instruction manual
A. GENERAL
- Maximum load capacity 50 kg.
- Make sure that the floor is suitable, i.e. level and loadbearing. The foot of the stand should not slide or sink, regardless if it is loaded or not.
- If the floor is uneven (or steps), suitable measures must be taken to ensure vertical position of the support tube,
-
e.g. by using the K&M compensation adapter 21445 (optionally available).
- Use sufficient personnel (if necessary two or more technically and physically suitable persons).
- Unauthorized persons must keep and maintain distance to the loaded stand.
- There is risk of tripping, if the safety distances are not observed. The danger can be minimized by using the eye-catching
-
warning strip 21402 (optionally available).
- Careful handling is required, as the adjustment possibilities hide the risk of entrapment.
- Only mount suitable speakers where the socket has the correct size and complies with quality requirements.
B. NOTE on REASOINABLY VORSEEABLE MISUSE
- The mounting position of the base/extension tube combination should be vertical and not inclined. Possible causes for misalignment are:
-
unsuitable floors, one-sided load, defective stand.
- Do not load the stand on one side (eccentric loading impairs stability of the installation respectively reduces the max. load capacity).
- ATTENTION: It is not allowed to shift the stand, especially under load, as this may lead to severe hazards
-
(tip over hazard, damage to components).
- For indoor use only.
C. BEFORE USE
- First of all, visually check whether the stand is complete and, if so, whether it is all right. Damaged stands must not be used - or only
-
after qualified repair.
- Loads and aids (e.g. ladders) must also be checked for suitability.
D. SETTING UP THE STAND
- First check the function and movability of the stand and its components in unloaded condition.
- Observe the information as mentioned in the chapter INSTALLATION INSTRUCTIONS.
- For maximum stability set the largest possible root diameter. This condition is given when the position of the bracing is horizontal.
-
WARNING: A bracing that is not completely opened may save space but jeopardises severely the stability.
- Tighten the clamping screws without using tools. Manual force is sufficient, especially since overtightening puts a strain on the components.
- When the height adjustment is completed, the locking bolt *10, 12 should always be engaged and the clamping screw *13 should
-
be tightened.
E. DURING USE
Safety during operation is based on:
1. OBSERVANCE of this instruction manual, especially the points mentioned under A-F.
2. PROPER OPERATION
2.
a. We strongly recommend that the speaker is always mounted, adjusted and removed by two or more technically and physically suitable
2.
a.
persons. One or more persons, depending on the weight of the speaker, should handle the extension tube plus load. A further person
2.
a.
should operate the locking bolt and the clamping screw.
2.
b. Never loosen uncontrolled the locking pin *8, 10, 12 and the clamping screw *13 of the extension tube
3. CONTROL OF LATERAL FORCES (due to tipping hazard).
3.
Lateral forces must be avoided at all costs. They occur when:
3.
a. the stand is inclined:
3.
a.
- measures: ensure a level flooring, use K&M 21445 compensation adapter
3.
b. eccentric balance of the load:
3.
b.
- measures: allow only marginal deviation
3.
c. external shocks (jolts, pulling on the stand, vibrations, wind, etc.):
3.
c.
- measures: ensure that the safety distances are observed and keep out unauthorized persons
3.
If these requirements cannot be met, the installer must provide further measures to ensure the safety of the installation.
3.
Examples:
3.
- stabilize the stand with ropes, reduce load and height, change position.
F. AFTER USE
- Retract the load slowly and in a controlled manner. Again, we strongly recommend, depending on the weight of the load, the employ two
-
or more suitable persons.
- Perform another visual inspection to ensure that the stand is complete and, as far as can be seen, in good working order. Damaged stands
-
must be subject to qualified repair before further use.
- First remove the speaker, then fold up the stand and store it in a safe place.
