Stand
The screws at the bottom of the stand loosen over time with use. The stand should be able to
be placed at any angle and stay where it is placed. If the stand begins drooping–that is, if it
won't stay where you put it–you probably need to tighten it. To tighten, all you need is two coins
(pennies work best). Place a coin in the slot of each screw and turn the right screw away from
you while turning the left screw towards you.
XYZ Stage Care & Maintenance
Over time and with use, you may find that the XYZ stage is wobbly when trying to focus an
image with the 200X lens. If the stage seems to wiggle a lot, especially when adjusting the
focus using the Z knob, you need to tighten the mast. The mast is the long metal cylinder that
holds the stage in place over the scope. There are two screws at the base of this cylinder that
keep it in place. First, remove the stage from its base (loosen the coarse focus knob and slide
the stage off the mast). Then use the hex wrench tool included with your XYZ stage to gently
tighten the two screws at the base of the mast. Be careful not to tighten the screws too much,
though, because they will make the X knob too tight to move fluidly.
If the X or Y knobs become too hard to turn, you can loosen (or tighten) the bolt using the other
tool that was included with your XYZ stage:
