INTRODUCTION
This manual provides an guide to the identification and repair of malfunctions of the DISCO
MODEL DFD-2S/8 and DFD-2D/8 FULLY AUTOMATIC DICING SAW.
Familiarity with its contents will enable you to obtain the years of dependable service that the
MODEL DFD-2S/8 and DFD-2D/8 FULLYAUTOMATIC DICING SAW is designed to deliver.
CAUTION:
This manual uses lint free paper. Since this paper is weakened by heat, do not place
near heat. Also when rubbing strongly with something such as an eraser, since the
printing will become thin and contaminated. Please take adequate precautions in
handling.

A. INSTALLATION
I Installation Environment
(1) Required space for this machine is 1,420mm (56″) (W)×1,100mm (43″) (D).
(2) Installation place should be determined by considering ease of operation and ease of
maintenance.
(3) Keep away from where temperature changes abnormally. Appropriate temperature is 20～25℃
±1℃(68～69.5°F±1.8°F) and humidity is 55±15%.
(4) Do not use a power source which flucturates frequently. Appropriate power is 200V±10%.
(5) Do not use a power source which emits noise. Permitted noise is less than 2,000V and its pulse
width is less than 500n/sec.
(6) Keep away from where the shock and/or sensible vibration are observed.

II Necessaries for Installation
(1) Power supply cord
(2) Piping hose
A hose provided as a standard accessory is 2m (79″) long. If you need a longer one, please tell
us previously. When you use other hoses, select those which have sufficient durability against
the proper fluids.
(3) Precision level
Asmall sized one.
(4) Tools
Supplied with the machine.
III Other Notice
(1) Install where floor has enough strength.
(2) Install where air, water, drain pipes, and power etc. can be supplied nearby.
(3) Connect piping hoses after cleaning their inside.
(4) Use dry air that’s filter is 0.003PPMWT/wt and its dew point is below than -15℃(5°F).
(5) Be sure to ground the machine.
(6) During installation do not load shock and /or use excessive force against the machine.
(7) After installation, remove all the hanging fittings and metal fittings for fixing.
(8) After installation, check that all the wiring terminals and piping joints are connected safely.
IV Installation leveling
Level the machine using the jack provided within the machine.
(1) Patch a jack sheet under the six jack bolts. Raise up equally until all casters are above the
floor.
(2) Place a level on a chucktable.
(3) Adjust level for four directions (before and behind, left and right) by turns shifting the jack
bolt.
(4) Set the level within 1 scale (0.02mm/1m)(0.0008″/39″) for all four directions.
(5) Check and confirm that all the jack bolts touch the jack sheet.

V Wiring Connection
(1) The following illustration shows the piping points and junction points at the rear of the
machine.
(2) Please verify the coupling connections.
(3) Be sure to connect the power source cord.
(4) The power source cord for the monitor is to be connected to a 100V table tap within the
machine through the cover.
(5) Signal cables for the monitor and for the signal lamp are to be linked to each connecter by the
cords leading from the machine.

VI Transportation
(1) Take off all piping and wiring.
(2) Draw water out of the machine.
(3) Take off the monitor.
(4) Take off the monitor base, the signal lamp, and the upper cover.
(5) Fix the Y-axis and the Z-axis with proper fittings.
(6) Fix the transfer arm with a thin string.
(7) Put on a hanging fittings for transportation.
(8) Run a pole through the hanging fitting and raise the machine with a crane.
(9) Notes for craning:
●Pay attention that ropes, etc. do not touch the machine.
●Do not shock the machine.
●Do not incline the machine excessively.
●Do not weigh on the cover.
(10) After raising up the machine, all the jack bolts are to be pulled in to the utmost. If they
remain below the casters, it is possible to break them when the machine is placed on the
ground the next time.

(1) Base Section
With theθ-axis section mounted on the table that slides on the straight rails, the base section
performs work transport, rightward/leftward feed for alignment, and reciprocating cutting
movements.
(2) Leadscrew Section
This section moves the slide table by means of the ball -bearing leadscrew coupled direct to the
AC servomotor.
(3) Cover Section
The splash cover, bellows cover, and water drain duct are provided to discharge the cutting
water out from the machine, protecting the mechanism against water.
