MODEL GS10
GEMMASTA 10” POWER FEED SAW
INSTRUCTIONS FOR USE
Place the GS10 saw on a firm stable bench or frame.
Fit the 10” blade onto the shaft, put on the flange and nut, and tighten the
nut securely. To access the blade shaft you will need to have the sliding vice
table fully forward (See Operating Instructions below on how to do this).
Slide the blade guide back until the blade is in the U section. Adjust the white
pads until they are just touching the blade. The pads should sit approximately
3-5mm behind the cutting edge of the blade.See FIG.5.
Fill the sump with your coolant until between the lines on the coolant level
indicator.See FIG.4.
Plug the three pin plug into an appropriate outlet, protected by a RCD circuit
breaker.
Your GS10 saw is now ready to use.
OPERATING INSTRUCTIONS
Unscrew the locking thumbscrew on the half nuts and release the catch to
allow the half nuts to spring apart (See FIG.3). Move the sliding vice table
towards the front of the machine.
Hold the material to be sliced securely in the vice, using the wing-nuts on the
top of the vice, then adjust the Levelling Screw (See FIG.1), until the top vice
plate is level. Tighten the wing-nuts again to ensure the material is securelt
held in the vice. The rock should not be higher than 3 ½”. If the rock is an
irregular shape, either grind some flats onto it so that the vice can grip
securely, or pack with wooden wedges. If the rock is not held securely it can
move during the cut and damage the blade.
Loosen the Back Wing-Nut and the Front Locking Knob (called the Front
Screw Lever in FIG.1) and wind the crossfeed handle (Slab Thickness Screw
Handle) to set the thickness of the slab. Tighten the Front Locking Knob and
then the Back Wing-Nut to lock the vice in place. Move the sliding vice table
towards the blade until the rock is almost touching the blade.
Lock the half nuts and lower the lid. Turn on the GS10 and allow the power
feed to push the stone into the blade until the cut is finished and specimen in
the vice has passed the cutting edge of the blade. The slab will fall onto the
left hand side of the sliding table. Turn off the GS10. The GS10 Lead Screw
has a safety relief so that if vice will only feed to a certain point and then
stop. This ensures that the Lead Screw, or the Gearbox, does not get
damaged.

When the cut is complete unlock the half nuts and move the vice table fully
forward. Loosen the Back Wing-Nut and the Front Locking Knob and wind in
the Crossfeed Handle until you get the required thickness of rock slice. Move
the sliding vice table up to the blade, lock the half nuts, lower the lid and start
the cut again.
PULLEY SPEEDS
The GS10 saw has a fixed blade speed. The blade speed is set to give the
most economical cutting with MK diamond saw blades and the sintered
continuous rim diamond saw blades and efficient cutting for the Diatrenn
diamond saw blades.
The power feed pulleys have two speeds (See FIG.2). The slow speed, about
6mm per minute, is used for any hard material, or for material that is larger
than 3” high. The faster speed, about 9mm per minute, can be used for all
other rocks.
HELPFUL HINTS
Before filling the sump with coolant, lay a hessian sack inside the sump. When
you wish to clean out the sump, first drain the coolant out and grab the
corners of the sack and lift out. This traps most of the sludge in the sack
leaving the sump clean. Lay the sack outside to dry the sludge and dispose
of thoughtfully.
Sharpen the blade regularly, either by using a dressing stick or a soft red
house brick. Most blade damage is caused by trying to cut with a blunt
blade.
IMPORTANT
Please read the Safety Instructions before using your Gemmasta GS10
machine.
For quick and easy reference read the “General Operating and
Maintenance Instructions”.

GENERAL OPERATING AND MAINTENANCE INSTRUCTIONS
Please follow these instructions carefully for the efficient use and maintenance of this equipment.
1. COOLANT
a. Always use coolant at the correct level. (See Fig.4)
b. U se of water is not recommended but allowed in special circumstances.
c. Diamond Saw Lube mixed 5 parts to 95 parts water is recommended for most cutting requirements.
d. Kerosene, Diesoline, transformer oil or light mineral oil can be used in a well ventilated area.
2. USE OF VICE
a. Hold rock in vice, level top jaw with levelling screw then tighten wing nuts.
b. Test rock for movement. If it moves loosen the screws and start again.
c. One complete turn of the slab thickness screw handle gives 1/16" sideways movement.
d. Lock vice to slab thickness screw by tightening front screw lever and back wing nut.
3. SAWING
a. Push slide table forward until the rock is nearly but not quite touching the saw blade.
b. Position the saw guard so that it is slightly above the rock and not in line with the vice.
c. Engage the half-nuts on the lead screw. (See Fig. 3)
d. Close the perspex hood. (If fitted)
e. Switch on the power.
f. Leave until slab is cut and the vice held rock has passed the cutting edge of the saw.
g. Switch off power.
4. TO CUT THE NEXT SLAB
a. Release half-nuts.
b. Slide the saw table towards the operator.
c. Firstly loosen the back wing-nut screw.
d. Secondly loosen the front lever.
e. Repeat operation as instructed in part 2b.
5. Keep the saw blade sharp by regularly running a small cut into a silicon carbide dressing stick or a worn grinding wheel.
6. Do not position the vice so that it will be cut by the saw blade.
7. Make sure that the saw guard is free from all forward movement of both the vice and rock by using the raising screw at the rear of the
machine. (See Fig. 6)
8. Keep the saw running centrally by adjusting the Teflon guides to be found beneath the sliding table. (See Fig. 5)
9. Always disconnect feed drive belt when sawing is finished.
10. Remember NEVER USE WATER
11. For TRIMMING SLABS the vice may be removed by taking out the two counter sunk screws that hold it to the sliding table. After having
removed the screws and completely loosened the back screw wing nut,the vice may be slid off to the right.
When trimming, use a gentle forward pressure so as to avoid pushing the blade sideways.
12. To clean out the coolant tank, which becomes necessary when the saw throws up too much sludge, firstly remove the
saw
for safety
against damage, secondly remove the four hexagonal headed bolts; the top section may then be lifted off the tank.
13. Always leave the saw clean by wiping off loose rock particles with a dry rag, and by cleaning the drive screws with a brush before finishing.
14. When replacing the top section remember to re-pack the rear section of the coolant tank in order to avoid "throw -out" of coolant liquid.
15. When placing the machine for use, have it slightly tilted toward the rear so that the coolant thrown up by the saw, will run back through
the drain holes, which should be kept free of dirt.
