Shoe Setting; Blade Wear; Blade Damage - Gerber HS750 Plus User Manual

SHOE SETTING

The tangential and swivel knife blade holders both have
adjustment shoes. The shoe acts as a cutting depth stop to
prevent the knife blade from cutting through the vinyl backing
material. This dramatically reduces the plotter's sensitivity to tool
force selection.
When shipped to you, the shoe setting is appropriate for use with
most Gerber vinyl materials. (The assembly, however, is not
intended for use with rubber stencil material.)
Before cutting any jobs, select the appropriate tool (tangential or
swivel) and make sure the tool force is set according to the
Suggested Tool Force Settings Chart . Then cut and weed a test
sign; check the shoe setting and make any adjustment required.
The weed should peel off easily but the knife should not cut
through the backing material.
Cutting quality is dependent more on the amount of knife blade
exposed than on the tool force setting.
If the tool force setting is correct but the weed does not peel
!
up easily, or letters peel up with the weed, adjust the shoe to
expose more of the blade rather than increasing the tool force
setting.
If the tool force setting is correct but the knife cuts through the
!
backing, adjust the shoe to expose less of the blade rather
than decreasing the tool force setting.

BLADE WEAR

The knife blade will dull slightly after cutting thousands of
characters. Blade wear is always a gradual change. Adjusting tool
force will extend blade life for a period of many days and even
weeks of use.

BLADE DAMAGE

CAUTION: Carbide blades are brittle and can be ruined by the
slightest chip of the cutting tip.
