level and make sure that there is sufficient water.

Tip Damage Damaged or bent tips do not cut gels efficiently.
Examine the cutting tip for damage and replace it, if
necessary
Cutting sheet damage Make sure that you are using the cutting sheet
(free gels) supplied with the spot cutter. If it has been used
several times or is severely scarred, replace it. See
Section 9, Accessories for ordering information. Do
not remove the soft film from the cutting sheet, as it
is important for cutting efficiency.
Tip height adjustment If the spot cutter is not cutting efficiently, recalibrate
the tip height as described in Section 3.
Gel hydration Gels that become dry are not picked up efficiently. If
gels become dry, increase the hydration frequency.
