POWER FEED SYSTEM AND VISE
Periodically the user should apply a thin coat of lubricating grease (wheel bearing or lithium grease) to the
3/8"- 24 screw feed rod to prevent the screw feed rod threads from becoming prematurely worn. If the threads
on both the bronze clutch blocks should become worn or “flattened” the clutch block will not securely engage
with the screw rod and it may disengage from the clutch block and not automatically advance the rock vise. A
replacement bronze clutch blocks can be obtained from Barranca Diamond. The rock vise assembly has cross
feed threads (Fig. 31) attached to an indexing or crank knob to laterally adjust the vise so that slab thickness is
accurately controlled before each slab cut. These threads should be lubricated periodically with wheel bearing
or lithium grease to allow for ease of rotation of the cross feed knob.
BLADE ARBOR ASSEMBLY AND PULLEYS
The BD10 Trim Saw is equipped with a 5/8"- 11 left-hand threaded arbor shaft with sealed ball bearings
mounted in an aluminum bearing arbor housing. A 2" OD x 5/8" bore die cast zinc coated pulley is mounted
on the shaft outside the oil reservoir. Unusual noises emanating from the saw tank or arbor area, slower than
normal cutting speeds and overheating of the shaft or belt are indications of arbor/bearing wear. Using the saw
with a worn arbor/bearing assembly can result in poorly cut rock slabs not to mention permanent damage to
other components of the saw. A new arbor/bearing assembly can be purchased from Barranca Diamond. It is
sold only as a complete unit as the bearings are installed in the aluminum housing by the factory.

VISE
Should the wooden jaw on the upper vise become worn or start delaminating, replacement jaws can be made
from 1/2" plywood.
