Statement: This device is intended for hoisting use and, in principle, should not be powered on before it is fully installed. If it is absolutely necessary to test the device's functionality upon arrival at the site, please follow the power-on testing procedure outlined below. Failure to adhere to the proper usage guidelines, resulting in equipment malfunction, will be considered as human error and will not be covered under warranty.
Place the hoisting device on an elevated surface, such as a table, so that the counterweight block is suspended in the air before performing any power-on testing.
All hoisting devices have been fully tested before leaving the factory. If the hoisting device is not installed on the stage top at the site, please follow the steps 1&2 above for power-on using. Only raise and lower the hoisting device over a short distance to test if it operates correctly. Once the counterweight block touches the ground and the hoisting device automatically stops, do not lower it further. Afterward, press the up button to retract the audio cable into the hoisting devices.
Do not release all audio cables from the hoist if it is not installed on the stage top. Any malfunction caused by improper use of the equipment that does not follow the usage specifications will be considered as man-made damage.
