HOW TO HANDLE MUSICAL MOVEMENTS:
1 Storage condition
. It is better to select a location to avoid direct sunshine, please put the musical movements in suitable place e.g. temperature 5~30oC (40~86oF) and humidity 65%RH under.
2 To avoid dust
. When the musical movements are moving or storage, be sure that dust, dirt and debris are kept away from musical movements. Small particles can stop the gear train.
3 Winding shaft
. When the musical movement spring is screwed with a winding key staked onto the winding shaft, do not add extra force to turn it clockwise , if over winding (70kg/mm above) that would result in the breakage of gears.(showed in Fig 1)
4 Drum shaft extension
. (1) If extra force (17kg above) to pull the 2# shaft then the 2# shaft will be breakaway the drum and result in deformation and breakage of movement.
(2) If extra force (15kg above) should be applied clockwise to drum extension shaft-named 2# shaft (showed in Fig 2) while music is being played , it will result in deformation and breakage of some gears. Therefore, while music is played normally, do not apply any addition force on the 2# shaft.
(3) If you try to turn the 2# shaft clockwise while the spring is run down, it will lead to disconnection of the spring.
5 When musical movements is assembled into your product, please put on the fingertip, make sure not touch directly to avoid rust.
. (1) Do not hold and press governor.(showed in Fig 3)
(2) Make sure not drop the movements from worktable or impacted by another heavy goods.
(3) Do not pile musical movements onto the worktable. Pick up movements one by one is recommended.
6 About packing
. When using large size winding key or disk key, make sure separated packing musical movements and key. The spring of movements must be relaxed.(showed in Fig 4)
7 Glue
. Do not use Formaldehyde, Resin, and acidic glue. Please select glue near PH = 7.
