Notes on Sawing (cont.)
Blade Force Limit (Spring Loaded Blade Micro-Switch)
Blade Force Limit is set by the knob on the Guide Arm. This sets a spring force on the blade back-up
bearing to interrupt excessive frame feed, and is indicated by the LED light blinking off during a cut.
A setting of “3” will normally protect the blade from excessive force when the feed rate is set so the
LED light remains on through the cut. This setting may be changed as needed for particular cutting
applications. For a few applications at slow feed rates, the blade force switch may be set to control
feed rate by interrupting down feed during the cut.
Speed Selection
The SpeedCut provides a range of blade speed, from 80 SFPM to 210 SFPM. Generally, softer
materials require faster speeds and slower feed while tougher materials require slower speeds
and higher feed pressure. If you are unsure, always start at a slower speed and slowly increase
to avoid decreasing blade life and ensure productive cutting.
NOTE:
If teeth wear off unusually fast,
use slower speeds.
THE UPPER EDGE OF THE BLADE
SHOULD NOT SEPARATE MORE
THAN 1/8” FROM THE FLANGE
OF THE BAND WHEELS.
Brass should always be cut with a blade, which has not previously cut other metal. Cutting work-
hardening materials, such as hastelloy etc., can present problems if feeding is too slow, because the
surface gets harder and the blade will not cut anymore. A new cut needs to be started and the feed
needs increased.
