The PICO-155S is a precision wafering saw for
sectioning delicate specimens ranging from fish
bones to microelectronic components. It is an
ideal saw for the metallographic laboratory. The
PICO-155S has the ability to cut at speeds
ranging from 50 to 1500 rpm, with loads ranging
from 0 up to 1000 grams.
The PICO-155S is very robust and durable
precision saw with its cast aluminum alloy and
stainless steel construction. The PICO-155S
utilizes diamond wafering blades ranging from 3
to 7-inches in diameter. A new feature and benefit
of the PICO-155S is that it uses a pump coolant
system for better lubrication at the cutting surface
as compared to traditional gravity drag lubricant
machines. This is especially important for cutting
with smaller diameter wafering blades.

1.4 Features
Improved Coolant System
The PICO-155S is an upgraded version
of the PICO 155P medium speed
wafering saws. Utilizing a 24V pump and
flexible coolant lines the PICO-155S
allows also for better coolant distribution,
even for smaller diameter wafering
blades. The advantage over the PICO-
155P is the ability to store information on
the three programmable buttons
Motor feedback
The PICO-155S is equipped with a 150 W
motor that has a feedback loop for
maintaining the cutting velocity, even
under higher loads and increased drag.
In addition, the circuit board has an
overload protection feedback which will
stop the motor if the blade becomes
jammed or pulls too many amps.
Easy to use
The PICO-155S is an easy-to-use
precision cutter with simple controls.
Simply align the sample and start the cut.
The variable speed motor can easily be
adjusted using the touch screen rpm
adjustment features. Following
completion of the cut, the motor will stop
and activate an audible buzzer.
Multi-purpose machine
The PICO-155S saw is a very versatile
precision cutter. It can be used as a
standard precision saw or it can be used
as a table top saw for cutting larger
samples; samples such as printed circuit
boards.

2.3.5 Installation -
dressing fixture
For optimum cutting
performance it is
recommended that the
wafering blade be
periodically dressed. This
will improve or decrease
cutting times as well as
extend the life of the blade.
Note: Even for hard ceramics
materials dressing is
important as the wafering
blades are metal pressed
blades and the metal from
the blade itself can coat or
blind the diamond thus
resulting in less efficient
cutting.
Proper dressing should be
conducted at slow speeds
and low loads (e.g. 300 rpm
and low feed rate). The
Dressing button should be
used to set the machine to
the proper rpm.
Align dressing fixture with lip on
front of casting panel with opening
in cover. Then attach the Dressing
Fixture to the cover with the allen
screws.
Select proper dressing stone.
Install onto the Dressing Fixture
and secure it with the allen head
screws
Slowly feed dressing stone into
wafering blade while running saw at
a slow speed

Please read this instruction manual carefully and follow all installation, operating and safety guidelines.

2.3.6 Installation
Sample fixture can be positioned
differently with respect to the
blade.
Note: For soft or gummy
materials it is recommended
that the sample be positioned
on the back side of the blade.
This will reduce the tendency
of the sample to jam the blade.
Machine can run at either 110V or 220V
power.
Connect the electrical plug and activate the
on main power switch (note the hood must
be closed for power to turn on at the front
panel). Verify that the emergency stop
switch is deactivated and the system will be
ready for operation.
Turn emergency
switch clockwise to
release
Power
switch
The power receptacle is equipped with a fuse
holder that takes a 3 amp fuse if running the
machine at 110v or a 1.5 amp fuse if running
at 220v.

Please read this instruction manual carefully and follow all installation, operating and safety guidelines.

3.0 Safety Guidelines
3.1 Warning Sign
! This sign points to special safety features on the machine.
3.2 Safety Precautions
Careful attention to this instruction manual and the recommended safety guidelines is
essential for the safe operation of the PICO-155S wafering saw.
Proper operator training is required for the safe operation of the PICO-155S wafering saw.
Any unauthorized mechanical and electrical change, as well as improper operation, voids all
warranty claims. All service issues need to be reported to the manufacturer / supplier.
!
Before operating, cutting chamber hood must be closed.
!
Use only certified wafering wheels from a professional supplier. Improper blade
selection voids warranty. (For appropriate blade selection, refer to the Abrasive Blade
Selection Guidelines Chart in Section 9)
!
Disconnect power before opening electrical back panel.
!
Replacement parts should be installed only by qualified personnel.
!
Securely clamp the part / sample to the working table. During cutting, consider that the
part may pinch and cause jamming of the wafering blade. Use the appropriate clamping
devices to avoid this occurrence.
!
Never start a cut under load.
3.3 Emergency Statement
Always follow proper operational guidelines and avoid bodily contact with coolants and
abrasives. Seek appropriate medical care for cutting injuries.

to the wafering blade. This is important in
order to prevent the blade from jamming and
to eliminate the oscillation (bouncing) of the
specimen during cutting.
2. For soft gummy materials it is recommended
that the sample be positioned towards the
back side of the wafering blade. For this
condition the blade is rotating up into the
specimen (note if the blade is positioned to
the front, the blade tends to grab the sample
and pull it down into the blade, thus jamming
and tripping the safety overload protection for
the motor).
3. A common issue with wafering saws is that
the specimen can bounce or oscillate during
cutting, especially if the sample is positioned
at the apex of the blade. In this case
reposition the sample, general more towards
the backside of the blade is better.
Shut-off screw
4.6 Automatic Shut Off
Adjust the height of the shut off screw so that the saw
will turn off after it completes the cut.
