Insert the “key” of the arm into the arm fixing plate. The main body must be placed 

at 90 degrees angle  against the fixing angle.

 

 

 

 

 

 

 

Turn the main body 90 degrees and insert the center gear of the mounting plate to 

the hole of the main body.

 

 

 

Fix the main body with the bind screw.

Step 2 - Install the Main Body

Step 3 - Adjustment and Operation

If the lid stay is sagging (A), turn the adjustment screw(Z) at the 

base of the arm until the lid stay straightens (B). The lid can then

be closed by pushing down gently on the lid. When the lid is 

closing, do not put additional pressure on the lid (to close more 

quickly, etc.) as it may damage the stay. If you have difficulty with

operation or adjustment of the lid stay, please contact Sugatsune

for technical assistance.
