SAFETY INSTRUCTIONS

Numbers marked with *, e.g. *14, refer to reference numbers in the diagram of the instruction manual
A. GENERAL
- The maximum centric load-bearing capacity adds up to 50 kg*
- Load capacity is a suitable PA with bushing ø 35 mm (e.g. Teufel ROCKSTER AIR)
- 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.
- The safety of operation is based, among other things, on the observance of these operating instructions, especially the points mentioned here
- under A-G.
B. NOTICE of "FORESEEABLE MISAPPLICATION"
- 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-bearing 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).
- Protect the stand from moisture and humidity.
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 2. ASSEMBLY 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 *2.4 / *4.8 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 *4.5 should always be engaged and the clamping screw *4.8 should be tightened.
E. EXTENDING/RETRACTING THE LOAD (see chapter 4)
- These activities must always be carried out by at least two suitable persons
- The "first person" has to hold the extension tube with bearing load firmly and securely, while the "second person" can use the securing
- elements locking bolt and clamping screw at any time, e.g. if the "first person" is not able to hold the tube and the load.
F. DURING USE
- Never loosen uncontrolled the locking pin *4.3 and the clamping screw *4.2 of the extension tube. Rather, the procedure described in
- Chapter E. (see above) must be followed.
- CONTROL OF LATERAL FORCES (due to tipping hazard).
- Lateral forces must be avoided at all costs. They occur when:
- a. the stand is inclined:
- a. - measures: ensure a level flooring, use K&M 21445 compensation adapter
- b. eccentric balance of the load:
- b. - measures: allow only marginal deviation
- c. external shocks (jolts, pulling on the stand, vibrations, wind, etc.):
- c. - measures: ensure that the safety distances are observed and keep out unauthorized persons
- If these requirements cannot be met, the installer must provide further measures to ensure the safety of the installation.
- Examples:
- - stabilize the stand with ropes, reduce load and height, change position.
G. AFTER USE
- Retract the load slowly and in a controlled manner. Please observe chapter E. (see above) and the procedure described in chapter 4 of the
- ASSEMBLY INSTRUCTIONS.
- 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 carefully and store it in a safe place.
