USAGE
-
Always wear proper apparel. Do not wear any loose clothing, gloves, neckties or jewelry that can get caught in the machine’s moving parts. Secure long hair with a rubber band or hair tie.
-
Always wear proper eye protection to protect yourself from any debris that may fly out while sawing. We recommend wearing safety goggles or safety glasses with side shields. Everyday glasses are not safety glasses. If anyone is around the machine while it’s in use, they must also wear safety glasses.
-
Keep work area well lit and clean. Make sure your work area is not cluttered.
-
Do not operate unattended. Adult supervision is required at all times. Never leave the machine running unattended.
-
Do not operate this machine while under the influence of drugs, alcohol or any medication.
-
Never run saw blades dry. Saw blades are designed to be used with a lubricant, such as oil or water, and will be ruined immediately if used dry. Always make sure you are using adequate oil or water while sawing so that rock dust doesn’t form. This dust contains chemicals that can be hazardous to your lungs if inhaled and is known to cause cancer, birth defects or other reproductive harm. To reduce your exposure
to these chemicals, work in a well ventilated area and wear a face or dust mask if the sawing operation is dusty. -
Never attempt to cut curves with the saw blade. Saw blades are designed to cut straight lines only. Ignoring this warning may result in a damaged saw blade and possible injury.
-
Never cut more than one workpiece at a time.
-
Some rocks contain poisonous elements. Avoid sawing rocks that contain uranium, mercury, lead, arsenic, etc. Make sure you know the material you are sawing.
-
Allow your trim saw to cool. By ignoring this warning, the 10″ Slab saw can overheat and deform the saw housing. We recommend cutting on the 10″ Slab saw for 30 minutes on, then allow 30 minutes off so the machine can cool down.
-
Do not force the tool or attachment to do a job it is not designed to do.
-
Saw blades continue to spin after turn off, eventually slowing to a stop.
-
Avoid awkward operations and hand positions. Make sure you have good balance while working on this machine. A sudden slip could cause your hand to move into the disc.
-
Always stay alert. You must be focused while working on this machine. Stones can catch on the saw blade and eject out of the sawing area.

OPERATING INSTRUCTIONS
-
Carefully unpack the slab saw from the box and remove all loose foam and accessories. Set the packaging aside should you need it in the future. Check to make sure all parts are present on both the machine and in the instruction manual. If you find any missing or damaged parts, call us immediately at 1 630-596-9909 or email us at sales@hitechdiamond.com. Place the slab saw on a table or flat surface in a well-lit location. The machine must sit level.
-
Remove the black saw table from the machine. Install the stainless steel arbor, washers, saw blade, nut, and brass bar according to Fig. A below. To do this, first, slide the stainless steel arbor onto the motor shaft. The two set screws located on the arbor must be over the flat part of the motor shaft.
Tighten these two set screws onto the FLAT part of the motor shaft marked red using the included Allen wrench. If you do not tighten the set screws to the flat part of the motor shaft , you will ruin the motor shaft by creating burrs. Next, slide two washers onto the arbor, then one of the two included saw blades, then two more washers. Slide the nut onto the arbor and tighten by turning clockwise. Do not over tighten the nut, it should only be slightly tighter than finger tight. Last, slide the brass bar onto the arbor, then insert the screw into the hole of the brass bar and the housing, then screw the brass bar into the housing using a Phillips #2 screwdriver (not included).
Note: Only use 10″ saw blades with 5/8″ arbor holes on this slab saw machine. -
The slab saw is designed to operate with oil or water. What you use is your preference. Never run the saw blade dry. Fill the reservoir with oil or water until the bottom of the saw blade is 1/8″ deep (Fig. B). Do not overfill the reservoir or there will be excessive oil or water spraying from the saw blade while you cut.
-
Replace the saw table. Insert the black spray shield (part #8) into the two slots located at the front of the saw table (Fig. C). The spray shield can be inserted in either direction.
-
Before turning your slab saw on, manually spin the saw blade towards you to make sure the blade is not in contact with the saw table.
If there is contact, see page 11 for instructions on how to position the saw blade for clearance. Note: Some saw blades tend to wave side to side as you spin them. They typically straighten out after turning the machine on. -
Put on safety goggles (not included), then turn on the machine by turning the power switch to the on position.
Note: Cutting speed depends on the type of saw blade you are using. Never exceed the saw blade’s maximum rpm. -
There should be a fine mist coming from your saw blade while it spins. If there isn’t, pour additional water over the blade until there is a mist.
Note: In use, always make sure the saw blade is properly lubricated. Never run dry. -
After each use, turn off the machine, then unplug your slab saw from its power source. Drain the water reservoir be removing the drain plug. Dry the machine and saw blade with paper towels or a cloth. You may also spin dry the saw blade by running it on the slab saw until it is completely dry.
Notes : Always dry your saw blade after each use to prevent rusting. Keep out of reach of children.
CUTTING TIPS
- Before you make the first cut, line up your rock or glass properly with the saw blade. Lightly slide the material into the saw blade until a groove forms, then push the material firmly through the saw blade. Do not attempt to cut curves with the trim saw, it is designed to cut straight lines only. As you near the end of the cut, reduce pressure to avoid a sudden “break-through”. Reducing pressure also gives you a cleaner cut. Note: Never force a saw blade, let the blade do the work.
- This slab saw is to be used for slabbing larger material. The rocks and glass you are sawing should never exceed more than 2/3 the size of the visible cutting area of the saw blade. The blade height of the 10″ slab saw is 3-3/4″. This measurement is taken from the saw table to the top of the saw blade (Fig. D).
- The red saw blade included with your saw has a sintered diamond rim that may require “sharpening” or “dressing” over long, continuous use. Simply put, the diamonds embedded into the sintered matrix of the blade are wearing down, and the metal sintered matrix surrounding the diamonds are deforming over them. This metal matrix needs to be abraded away to expose the diamond surface. Dress and sharpen sintered saw blades with aluminum oxide, silicon carbide stone, dressing stick or brick. Run 3-4 times through the saw blade for a quick fix.
Note: Always abide by your saw blade instructions. Not all saw blades should be sharpened or dressed, as it can ruin the saw blade.
MAINTENANCE
ARBOR & MOTOR SHAFT
Oiling (or greasing) the inside of the stainless steel arbor and the motor
shaft is required because the arbor and motor shaft are made of different
materials. Over time, they can seize to-gether, making it impossible to remove
the arbor from the shaft. Every two months or so, remove the arbor from the
motor shaft by loosening the two set screws using the included Allen wrench,
turning counter-clockwise. Once loosened, slide the arbor off the motor shaft.
Apply a few drops of motor oil, way oil, lithium or water pump grease inside
the arbor where it fits onto the shaft. Also apply a few drops of oil or
grease onto the motor shaft, rubbing to coat the shaft lightly. Make sure
there is no excess oil so that oil doesn’t drip down the motor shaft and get
into the motor. This will cause an instant motor burn-out. Replace the arbor
onto the motor shaft using the Allen wrench to tighten the two set screws onto
the flat part of the motor shaft.
ARBOR & BRASS BAR
Greasing the inside of the brass bar where the arbor fits into is required
because the arbor and brass bar are made of different materials. Over time,
they can seize together, making it impos-sible to separate from each other.
Insert lithium grease or marine grease inside the brass bar
(Fig. E) every time you change the saw blade. We suggest greasing this
part more frequently than when you oil (or grease) the arbor and motor shaft
because these parts create more friction.
Note: Only use lithium grease or marine grease. Using different oils may
cause the arbor to lock-up into the brass bar, making it impossible to remove.
CLEANING
After each use, drain the water reservoir by re-moving the drain plug. Any
used water must not be disposed down a sink, as rock sediment can harden like
cement, closing off the drain. Dry the machine and saw blade with paper towels
or a cloth. You may also spin dry the saw blade by run-ning it on the trim saw
until it is completely dry. Notes: Always dry your saw blade after each use to
prevent rusting. Keep out of reach of children.
SAW BLADE ADJUSTMENTS
BLADE POSITIONING & CLEARANCE ADJUSTMENTS
Follow these four steps to adjust the position of the saw arbor and saw blade
so that the blade does not make contact with the saw table. This process may
require trial and error.
- Remove the saw table, then remove the brass bar. Loosen the two set screws located in the saw arbor using the Allen wrench, turning counter-clockwise (Fig. F). Once loosened, the saw arbor can slide side to side.
- Replace the saw table and position the saw blade so that it is not in contact with the saw table. Your blade should spin freely.
- Remove the saw table to tighten the two set screws using the Allen wrench, turning clockwise, then replace the brass bar. Make sure to tighten the set screws to the FLAT part of the motor shaft.
- Replace the saw table and manually rotate making contact with the saw table one last time
before turning the slab saw on.
NEED A REPLACEMENT SET SCREW?
The two set screws located in the saw arbor are available at your local
hardware store. The size of the set screws are 18-8 stainless steel, cup
point, 10-32 thread, 3/16″ long.

FAQS
-
What lubricants can I use with this slab saw?
This slab saw machine is designed to be operated with oil or water. We recommend water because it is less messy to work with than oil. If you are using water as a lubricant, we suggest adding a coolant to reduce heat buildup between the saw blade and stone. Some stones, such as tourmaline for example, fracture with too much heat. No one likes a fractured stone! -
How large should the material be that I’m cutting?
This slab saw is to be used for slabbing larger material. The rocks and glass you are cutting should never exceed more than 2/3 the size of the visible cutting area of the saw blade. The blade height of the 10″ slab saw is 3-3/4″. This measurement is taken from the saw table to the top of the saw blade (see below). -
What size saw blades can I use on this slab saw?
Only use 10″ diameter saw blades on this slab saw machine. Please note that only saw blades with 5/8″ arbor holes fit onto the saw arbor. -
In regards to saw blades, what do “core” and “kerf” mean?
-
Core is the thickness of the inside of the saw blade (the core), while kerf is the thickness of the saw blade’s rim. When purchasing a saw blade, the dimension of the kerf is what matters most because the kerf determines how thick of a cut you will get. FYI – the kerf gets thinner over time as the saw blade wears away with continuous cutting.
-
What is the recommended RPM for this slab saw?
The RPM speed depends on the type of saw blade you are using and the saw blade’s maximum RPM. Remember to never exceed the maximum RPM of your saw blade.
TROUBLESHOOTING
-
Why is there excessive oil or water spraying from the saw blade?
If there is excessive oil or water spraying from the saw blade while you’re cutting, this means you have overfilled the water reservoir. Fill
the reservoir with water (or oil) so that just the bottom of the saw blade is sitting in it, about 1/8″ deep (see below). -
My saw blades keep rusting. How can I prevent this?
Rusting occurs when the saw blade is not properly dried off aft er each use or if the saw blade is left sitting in the saw machine’s water reservoir when not in use. The best solution to prevent rusting is to remove the saw blade from your trim saw aft er each use and dry with a paper towel or cloth. Remember to always keep saw blades away from children. -
What happens if my saw machine overheats?
The housing that the slab saw is made out of is polyethylene, which can deform if the machine is run too long, causing the machine to overheat. To prevent this from happening, you must take time to cool your machine. We suggest running your slab saw for 30 minutes on, 30 minutes off to cool. Alternatively, you can use an external fan to blow air through the vent located on the side of the motor housing. This will help prolong usage time. -
I can’t remove the arbor from the motor shaft.
If you can’t remove the arbor from the motor shaft using the Allen wrench, it is most likely because the arbor and motor shaft seized together. This is a result from not oiling the inside of the arbor according to the oiling instructions on page 10. If it is impossible to remove, please contact Hi-Tech Diamond at 1 630-596-9909, and one of our specialized technicians will help you over the phone with the correct removal. -
Do you sell electrical spare parts for my slab saw? Whom
do I contact if I need a repair or replacement for my slab saw?
Due to the technical nature of our machines, we do not offer electrical spare parts for you to install yourself such as motors, speed controllers, rectifiers, etc. Instead, we offer a repair
service that is done in-house by our qualified technicians. For more information about our repair service, visit hitechdiamond.com/repairs. -
