Barranca Diamond HP18 Slab Saw - Manual (Page 15)

15
Never operate the saw with the hood up, or hold a sharpening stone to the blade by hand. Use of the
vise is mandatory under all operation conditions. Never over-sharpen the blade too much as it will cut
down the blade life. Periodically, the diamond blades should be "dressed open" or sharpened by mak-
ing several passes through a green carbide brick, aluminum oxide (60-100 grit), or abrasive stone such
as cinder block or red brick.
Should the saw experience difficulty in cutting, inspect the diamond blade for loss of tension, temper,
wobble, pounding, dishing, or glazing of the diamond cutting edge (kerf). Resharpening of the blade
may be required periodically when cutting dense and hard material. Segmented rim and continuous
rim 303 Pro blades are NOT repairable. Be sure blade flanges are at least 1/6 the blade diameter (i.e.
a 24" blade requires a set of flanges at least 4" in diameter). Undersized flanges will result in blade ten-
sion loss.
Carriage and rock vise
HP18 & HP24 STARTUP & ADJUSTMENT
Rock Vise/Carriage Operation
The carriage and rock vise work together to securely hold the rock specimens during movement of the
material in the carriage toward and into the notched rim diamond blade. The rock specimen should
not exceed the maximum material size for the saw you are using (as shown in the table on the saw
specifications page). It is very important that the rock specimen be tightened by use of the hand screw
threaded bolt at the back of the rear vise plate once the spec-
imen has been pushed forward and in firm contact with the
front plate. Both front and rear vise plates are constructed of
1/2" plywood to give firm and tight grip to the rock specimen.
Should replacement be needed due to wear or breakage,
the parts can be ordered from Barranca Diamond Products.
Wedges of wood can be used in the voids between the rock
specimen and vise plates to enhance the surface contact and
pressure hold prior to tightening the vise screw bolt. Be sure
to recheck the tightening screw prior to operation.
DO NOT FORCE the blade to cut, it will do the job better and safer at a rate for
which it was designed.
