FOR YOUR SAFE WORK AND CORRECT INSTALLATIONThis symbol denotes prohibited action.
This symbol denotes what must be done.

Caution: If these cautions are not followed, it may result in injury or damage.
It is necessary to manufacture the cabinet with sufficient strength so as to endure the weight of the lid.
Do not put an unbalanced load on the hinges.
Use more than 2 hinges per lid and adjust hinge center.
Provide a stopper to prevent the hinges from opening beyond the fully opened angle. Hinges may be damaged if no stopper is provided.
If the housing that the hinge is installed on is rotated the hinge may suddenly open. Provide a lock to prevent the hinge from opening in this case.
This product is for indoor use only. Do not use outside or anywhere it will be exposed to water.

1 Maximum Lid Torque Calculation
Calculation formula: Mu = W x L x cosθ

2 Relationship between lid torque and hinge torque
The chart shows an ideal example of lid torque and hingetorque.
Lid torque Mu > Hinge torque・・・Lid will close.
Lid torque Mu < Hinge torque・・・Lid will open.

Hinge Center■Please confirm whether hinges move correctly if Lid torque Mu is Max orMin.
G: Center ofgravity

Example of lid size: X = 43 cm, Y = -10.5 cm, L = 44.3 cm, W = 10.8 kg
