Adjustment of Glide Bars
When glide bars will not slide smoothly, adjustment of glide bars is necessary.
First, check whether or not the slides are parallel to each other, if not, loosen
screws under the slides. Adjust the slides to make sure that they are parallel.
If this doesn’t solve the problem, loosen screws underneath the tray table and
adjust the rail. There should be a 0.01 to
0.02 mm end clearance between the slide and rail so that glides will move
freely.
Lubricating the machine
Use a modest application of light machine oil on the rail to ensure free
movement of slide and rail. Also use a small amount of light machine oil
on bearing wheels as required.
WARNING
: do not lubricate the brake
Cleaning the machine
Glide bars and clamps must be kept free of wax to prevent slippage. Use
alcohol or light, nonabrasive cleaning detergent to remove wax built-up and
dirt from the glide bars and attaching areas of the string clamps.
WARNING
: Do not use sandpaper or any other abrasive material on the
glide bars and attaching area of the string clamps.
