9.Dentist’s Tray
(1)Over Arm and Floor Arm
1)Operation
The tray can be rotated horizontally or lifted up and down.
Grip the tray’s handle and move it carefully.
2)Adjust Action of Movable Arm
The action of the movable arm can be adjusted depending on how
much weight is placed on the tray.
Adjust it in the following way:
a)For a heavy load (or to make the up and down action stiffer)
Tighten the movable arm’s knob to make its action stiffer and keep it
from sagging up a heavy load.
Tightening this knob completely will lock the arm in place and keep
it from moving up and down.
b)For light loads (or to make its action looser)
Loosen up the knob for freer tray action.
Keep a grip on the handle when loosening the
knob. Otherwise, the tray could suddenly spring
up if it was being held in a low position.
WARNING
Never set objects weighing more than 30N(3kgf) on the tray table. Do not use
force to move the tray and do not subject it to bumps or other physical shocks.
>>A load greater than 30N could cause the tray to fall down resulting in bodily
injury or damage to equipment.
Ensure the tray knob is properly adjusted.
>>Otherwise, the tray could suddenly spring up or fall down resulting in an accident
or damage to equipment.
