MAINTENANCE

This adjustment will help the clutch block shoe to snugly engage the stainless steel feed screw by applying
pressure to the brass pressure block below the carriage casting. Should you have trouble with this adjustment
call Barranca Diamond at (800) 630-7682 for factory assistance in clutch adjustment.

Periodically, it will be necessary to replace the bronze clutch block shoe once the 3/8"-24 threads are flattened
or stripped. You may purchase the clutch block and pressure block direct from the factory. See parts lists on
pages 20 and 21 to order correct parts by part number and description of part(s).
Repeat this process if necessary to readjust the engage/disengagement clutch to improve positive feed move-
ment of the carriage-vise system. If the gap between the shoe and pressure block is too tight the clutch will not
engage correctly. It will need to be adjusted so that the pressure block position is repositioned by turning the
set screws counterclockwise to raise the block away from the feed rod.
LUBRICATING OIL REPLACEMENT
The HP14 Slab Saw requires periodic routine maintenance to remove and
discard properly the build up of rock mud "sludge" and dirty lubricating
fluid (oil) from the oil reservoir pan. It will be apparent to the user from the
condition of the oil that the lubricating fluid is dirty and needs to be changed
and solid sludge removed from the oil pan if a thick and viscous oil residue
builds up on the saw vise/carriage, and inner tank walls. The liquid oil can
be removed rapidly using the drain pipe attached to the bottom drain hole at
the base of the oil reservoir (Photo 13).

A five gallon bucket or collection container can be placed under the outlet cap of the pipe and the cap removed
with a pipe wrench or channel locks to let the free oil flow into the bucket for proper disposal. The sludge resi-
due will likely not flow into the drain pipe upon removing the cap from the drain pipe. Therefore, a portion of the
sludge (solids) can be removed with a scoop, large spoon or spatula when the slab saw oil lubricant is drained.
Once the majority of the liquid oil has been drained, remove the blade from its shaft and then remove the bot-
tom oil pan from the saw's main tank top by unbolting the fastening screws. Lift off the upper tank and hood
with help from another person and extract the sludge pan and set it aside. With a spatula or spoon, scoop out
the sludge/mud to clean out the build up of sludge. Once the sludge is removed, wipe clean the inside of the
tank with disposable rags or towels, replace the gasket between the bottom pan and main tank body and reas-
semble the saw. Refill the cutting lubricant to the proper level (1/4 to 3/8" of blade kerf immersed in cutting oil).
Be sure to check the fluid level of the cutting lubricant inside of the oil reservoir after every 2 to 3 hours of use
as the fluid will be absorbed onto the rock slabs, combined with rock mud (sludge), and lost due to heat, mist-
ing and evaporation as well.
