HP30 OPERATIONS & ADJUSTMENTS
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 as it will cut down the blade life. Periodi-
cally, the diamond blades should be "dressed open" or sharpened by making 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 tension loss.
Carriage and rock vise
CAUTION
Rock Vise/Carriage Operation
The carriage and rock vise work together to securely hold the
rock specimens during movement of the material in the car-
riage toward and into the notched rim diamond blade. 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 specimen has been pushed forward and is 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 con-
tact 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.
