Handle Crank Cross Feed Adjustable Rock Cut Index Control
To use the crank cross feed index wheel, simply clamp and
secure the cutting material into the vise by using the clamp
screw to tighten the vise and turn the wheel crank until the
desired slab thickness is achieved You can measure the
slab thickness with a ruler prior to cutting, but remember,
depending on blade thickness, the amount of waste material
from the rock specimen will vary. Always allow the rock cut
to go to completion before opening the hood of the saw. Do
not over crank the vise to the far left or right position on the
carriage.

Clutch Adjustment
The clutch system is comprised of a lever to cam assembly that raises and lowers a bronze clutch
shoe. Should the clutch not fully engage and move the carriage, loosen the countersink screw below
the vise table inside of the carriage and tighten the two allen head screws to depress the bronze pres-
sure block. Adjust set screws in one-half turn increments. Be sure to retighten countersink screw after
each adjustment. Re-engage the clutch and restart saw to check if feed is working properly. If not,
readjust set screws another 1/2 turn, retighten countersink screw and restart saw to check feed.
HP18 & HP24 STARTUP & ADJUSTMENT
Automatic Feed Engagement/Disengagement System
Highland Precision slab saws are designed for operation with an adjustable clamping vise and self-
feeding carriage mount. The clutch engagement/disengagement lever should be positioned in the
straight upward (12 o'clock) position to disengage the clutch and allow the carriage to move freely
along the rails. To engage the clutch, simply turn the lever in the downward (3 or 9 o'clock) position to
securely engage the bronze shoe and block with the stainless steel thread. Should the carriage not
move freely on the rails, clean the rails with a clean rag and place a liberal amount of wheel bearing
grease on all surfaces of the steel rails to assist in the free movement of the carriage.
