Automatic Shutoff (HP18 & HP24)
Once a rock specimen has been securely vised inside of
the saw, the operator can adjust the automatic shut-off
control switch by moving the link chain to the desired
position where the rock and vise are anticipated to
complete the desired cut. By moving the vise forward
with the rock in place, the operator can see where the
chain slack needs to be adjusted to stop the unit
automatically. Movement of the vice will tension the chain
to a point where it will pull the ON/OFF switch to the OFF
position and shut-off the power feed and blade shaft motor
automatically.

New Blade Break-In Procedure
Be sure to wipe off any and all carbide or abrasive grit particles
from the cross and main feed screw rod and rails. It is recommend-
ed, upon initial use of the Highland Precision slab saws, to cut ma-
terial that is abrasive yet soft such as carbide brick or cinder block
to remove the factory paint and open the blade’s diamond segment
for optimal cutting performance. Use of a sharpening stone such as
aluminum oxide or carborundum is acceptable only if the sharpen-
ing brick is placed securely in the vise.
