Adjusting the Seam Phantom®
To ensure the tightest possible seams, each Seam Phantom® is checked for squareness before it leaves
the factory. Slight variations in grinders and polishers can affect the finished product so shim washers
are provided to make final adjustments. A newly assembled Seam Phantom®/grinder should initially be
checked with a good square and then tested and adjusted utilizing a sample seam ground on scrap stone
as follows:
1. On a scrap piece of stone set up the Glide Guide and grind the first half of a finished seam
per the instructions on page 13 thru 15 of the manual, steps 1 thru 6 and steps 8 thru 12.
Skip step 7, “Back Grind”. Dress the entire edge of the stone with the turbo pads to 150 grit.
Make sure all the chips in the upper edge of the seam have been eliminated.
2. On a second scrap piece of stone create the mating half of the seam in the same way.
Make sure all the chips in the upper edge of the seam have been eliminated.
3. Place the two halves of the finished seam together. Make sure the top of the sample is even
and flat and observe the gap at the edge of the seam. The seam should be tight on the top
edge. A slight gap on the bottom edge is acceptable and sometimes desirable. It is a matter
of personal preference. Some fabricators prefer to make perpendicular tight seams from
top to bottom. Other fabricators prefer a slight gap on the bottom to ensure the top is
always tightest.
4. Add shim washers to the attachment screws as required to create the desired seam.
a) To correct a gap on the top edge, shim washers can be placed between the grinder and
Seam phantom® (between the air adapter and Seam phantom® on air powered units) on
the top two attachment screws. Utilize one or two washers on each screw as required.
See Figure 3 (electric) or 8 (air) for correct washer location.
NOTE: A single washer added to the top two attachment screws changes the angle of
the turbo pad by approximately ¼ degree and will result in approximately .005”
additional stone removed at the bottom of a 3cm sample (the approximate
thickness of a human hair). This will correct an approximately .010” gap at the
top of a finished seam when both halves are brought together.
b) Shim washers may also be utilized on the lower two attachment screws to close an
overly large gap on the lower edge of the seam.
5. After the washers have been added repeat the process to ensure the desired seams are
being produced.
6. The Seam phantom® is now set to produce consistent tight seams. Occasionally this process
may need to be repeated as the plastic base plate that slides on the Glide Guide wears.

USE INSTRUCTIONS
Before Using the Seam Phantom®
Before using the assembled Seam Phantom® be sure to complete the following preparations.
Supply the Specified Voltage (electric version)
Supply the voltage specified on the nameplate of the grinder. Otherwise damage could result to the
machine, or increase the risk of personal injury.
Install a Ground Fault Circuit Interrupter (GFCI) (electric version)
To prevent electrical shocks, be sure that the power circuit being used is protected by a GFCI device
or be sure to install the supplied ground fault circuit interrupter (GFCI) between the main power
supply and the cord of the machine.
Keep Water Out of the Grinder (electric version)
Do not let water into the motor of the electric grinder. Water inside the machine will weaken the
electrical insulation of the motor and may result in electric shock. Ensure the spray skirt (see Figure
4 to 7) and splash guard angle (see Figure 3) are installed at all times during use.
Organize the Work Area for Safe Operation
Before beginning operations, make sure that the work area conditions are well organized for safe
operation of the Seam Phantom®
Use Proper Safety Gear
To prevent damage to eyes from flying debris, wear protective glasses or face shield. Be sure to
wear waterproof safety boots, appropriate hearing protection and dust protection as required.

How to Operate
Work Piece Setup
1. Set your work piece on the work bench and secure it using appropriate clamps. Take
care to leave enough overhang for the grinding pad to get all the way to the end of the
slab, and for the guide rail clamps to clear the work bench.
NOTE: To allow for removing material, the seam should be “overcut” during the sawing
process by as much as the largest chips in the upper edge (typically around 1 mm
or 0.04”).
Guide Setup
2. Using your template or other method, determine final location for the seam. Mark with
tape cut to the template or other preferred method.
3. Use two gauge blocks to line up the Glide Guide straight edge parallel to the seam. See
Figure 10 below.
4. Your Glide Guide (guide rail) should extend a minimum of 3” (7.5 cm) past both sides of
the stone. Make sure that you select the correct size Glide Guide for your work piece. A
48” Glide Guide is supplied with each kit and will work for most standard seams. 72”
and 92” Glide Guides are also available.
5. Clamp Glide Guide straight edge using appropriate clamps on the back edge (the edge
opposite the seam) at each end.
6. Remove gauge blocks after the glide guide is clamped in place and prior to grinding any
stone.
FIGURE 10 –Gauge Block Use

Page 14
Back Grind or “Undercut”
7. The back grinding is done using the 2" cup wheel. Ensure adequate water flow is
provided by adjusting the valve. Lock the 2” cup wheel into the snail lock adapter and
back grind slightly more material than you'll be dressing off with the turbo pads.
Example –If 1 mm is going to be removed with the turbo pads, approximately 1.5 mm
should be removed with the 2” cup wheel. One full turn of the Depth Adjustment Knob
(see figure 11 below) equals 1 mm. This material should be removed in ½ turn (0.5 mm)
increments until 1.5 mm is removed.
Be sure to stop the back grind short of the front profiled or polished edge to avoid a
large gap in the front edge. This back grind will allow the turbo pads to dress the upper
portion of the seam more efficiently and will also provide a rough surface on the lower
portion for the seaming adhesive to adhere to.
Caution
The SL3® Cup Wheel is made to be used with water. With the electric model, adjust water flow to
ensure the water is hitting the “backstop” of the SL3® 2” cup wheel and splashes onto the grinding
area. With the air model, the water is fed through the center water feed of the polisher. DO NOT
OVERHEAT the Cup Wheel by operating it dry. Max speed for the 2” Cup Wheel is 10,000 RPM.
Dressing the Seam (Suggested Process)
8. Start with either the SL3® 60 or 150 Grit Turbo Pad. Lock the desired turbo pad into the
snail lock adapter.
NOTE: Which grit to start with will depend on the size of chips in the edge, and how
much material is to be removed. Use the 60 grit to remove large chips and
excess material. Use the 150 grit for smaller chips and fragile material.
9. Turn the adjustment knob counter clockwise to back the turbo pad off the stone so it’s
not touching the stone.
10. Turn on the power and water. Adjust the water valve to ensure an adequate water
supply.
NOTE: The electric version has the water valve mounted on the Seam Phantom® itself.
Use the valve to control the volume of water being used and to avoid excessive
water spraying onto the grinder. The grinder will last longer if it is kept dry.
Caution
The SL3® Turbo Pads are made to be used with water. Adjust the water valve to ensure an adequate
water supply. DO NOT OVERHEAT the Turbo Pads by operating them dry. Max speed for the SL3®
Turbo Pads is 4,000 RPM.

11. Turn the adjustment knob clockwise until the turbo pad just touches the stone (this is
your zero point) and begin grinding the seam back and forth keeping the wheels in
contact with the vertical edge of the Glide Guide as shown in Figure 11 below.
12. Starting from the zero point, turn the adjustment knob in small increments to gradually
cut deeper. Keep working the Seam Phantom® back and forth grinding away the stone
until the cut is almost to the final seam location (stop short so you can finish with the
300 grit turbo).
NOTE: For best results, only apply pressure to the tool using aluminum knob above the
flat surface of the straight edge. Do not apply pressure via the polisher or by
pushing on the adjustment knob.
13. Repeat process using the 300 grit pad. (This is optional and depends on the type of
material being dressed. You might find that your results from the 150 grit pad are
sufficient.)
14. Continue until finished edge is at the desired seam location with no edge chipping.
Continuing until pad is no longer grinding the stone along the entire edge will ensure a
straight and chip free edge.
15. To check the straightness of the seam, with the power and water off, the Seam
Phantom® can be lightly rolled from left to right across the Glide Guide to see if the
turbo pad drags or turns on a high spot. If the turbo pad does not drag or turn, the
seam is finished. If there is an area where the turbo pad drags or turns on a high spot,
this area needs to be corrected. Without moving the Depth Adjustment Knob, turn on
the power and water and continue working the seam until the high spot is removed.
Quick Tip: This is a suggested process that will work on most natural and engineered stones when
starting with a good bridge saw cut. After removing 1.5 mm of material with the 2” cup wheel as
described above, switch to the 150 grit turbo. With the 150 grit turbo, remove 0.75 mm (¾ turn)
taken in ¼ turn increments. Be sure that the 150 grit turbo is no longer removing material before
switching to the 300 grit turbo. With the 300 grit turbo, remove 0.25 mm (¼ turn) taken in 1/8 turn
increments. Be sure that the 300 grit turbo is no longer removing material before checking the seam
for straightness.

CLEANING AND MAINTENANCE
Caution
Always be sure that the tool is switched off and unplugged before attempting to perform inspection
or maintenance.
Caution
The grinder air vents need to be kept clean. Regularly clean the grinder air vents or clean the vents
whenever they start to become obstructed.
Caution
To maintain product SAFETY and RELIABILITY, repairs to the grinder or air polisher should be done by
an Authorized or Factory Service Center.
The following procedure will extend the longevity of your Seam Phantom®
1. Electric version - Fold back the spray skirt and blow out the grinder vents after each use using a
dry air supply to remove any dust or moisture. This will extend the life of the electric motor.
2. Air Version - Perform regular lubrication and other maintenance of the air polisher as
recommended by the manufacturer
3. Cleaning Guide Rods and Bushings - After heavy use, the in and out adjustment of the Seam
Phantom® may become “stiff”. Performing the following steps should correct this. See Figure 12
below.
a. Disconnect the water feed hose (electric version only) at the valve end with the quick
disconnect tube fitting, by pushing the ring towards the hose fitting.
b. Turn the adjustment knob counter clockwise until the adjustment screw disengages from
the square nut and the two halves of the Seam Phantom® can be separated. Do not lose
the square nut.
c. Use a paper towel or other soft material and push through the bushing holes, sliding back
and forth until all grit is removed.
d. Using a soft towel or material, wipe the stainless shaft guide rods clean.
e. Clean screw threads on the adjustment screw with water and a brush.
f. Reassemble the two halves of the Seam Phantom® and re-connect the water hose by
pushing it in until it snaps in place.
