A. Suspended platform and hoister
1. The concatenation length of platform can not over the specified length set by relevant authorities or requested in use manual.
2. Each part will be connected well by pins and bolts should be tightened well to ensure reliable. Welding place should be done well and no missing welding.
3. Limit, limit overload protection, limit protection device should be complete and intact.
4. Motor, hoister, should not overheat and abnormal sound and so on.
5. After using every day, we should turn off the power switch and lock well the electrical box.
If open storage, we need to do water-resistant measures to prevent rainwater entering into hoister, safety lock and electrical boxes.
6. To timely remove the dirt in hoister surface and avoid damage of internal parts caused by debris into mouth of rope.
7. To timely replace and fill the specified lubricant according to product instructions.
8. N0-load operation must be carried out before the job. If there are unusual circumstances we should contact professional workers to inspect them.
9. To avoid a collision when installation, transportation and using process.
10. Regular maintenance should be done by professionals.

B. Safety lock 
1. The safety lock must be used within the standard period.
2. Safety lock should be flexible and reliable. We should promptly remove glue, mortar and debris on the rope and avoid these things into lock to reduce safety.
3. When it appears fails, it should be repaired by professionals. After inspection, we could use it again. Never attempt to disassemble and repair them by oneself.
4. To prohibit artificially opening handle.
5. When the safety rope under tension we can not open the handle.
6. To prohibit using Safety-lock braking in normal using.
7. After using every day, we should drop the platform to the ground and relax the working wire rope and let the safety lock arm in relaxed state.
8. We should test the rope-lock before using. After testing well it can be used.
9. The safety lock which reaches its predetermined period should be sent to manufacture for repair and re-calibration.

C. Suspension mechanism
1. To fully inspect the welding chink before operation to avoid missing welding. All the couplings and fasteners should be complete and reliable and tested. IF they are loose, we should reinforce them.
2. The using of balance weight should accord with the request in using manual. We also take fixed measures to prevent slipping and losing.
3. The spacing between two hanging points of suspension mechanism should equal to the spacing of two hang points of suspended platform.
4. To avoid collision when movement and installation.
5. To timely clear the filth in surface after using. And do not use sharps to protect paint.
6. If there are cracking occurs and member deformed, we adopt reasonable process to repair it and if there is shedding we should promptly fill paint to avoid corrosion.

D.Electrical control system
1. Start frequency is not greater than 6 times/min and uninterrupted working time should be less than 30 minutes.
2. Cable length can not longer than 100 m and it should be protected by pulling protection measures.
3. To often test the connection and if there are some looses we should tighten them.
4. We should fix the cable on suspended platform to avoid being pulled for plug.
5. Electrical boxes, limit switches and cables should be avoided external shocks.
6. Turning off the power and locking well electrical box after using and place cover to avoid rain.
7. IF there are some problems in electrical system you should contact professional personnel to do repairing job.

E. Wire rope
1. We must use the wire rope stipulated in using manual. Do not use other wire rope to substitute for.
2. To correctly dispose the hammer.
3. Never connect wire rope.
