Introduction
The SASE PDG 8000 planetary diamond grinders are designed for wet or
dry grinding of marble, terrazzo, granite and concrete. Their applications
range from rough grinding through to a polished finish.
It is extremely important all users be familiar with the contents of this
manual before commencing operation of either machine. Failure to do so
may result in damage to machinery or expose operator to unnecessary
dangers.
IMPORTANT!
Only staff that has received the necessary training, both practically and
theoretically concerning their usage should operate the machinery.
Transportation
The machine comes equipped with an electronic system called a variable
speed drive or a frequency converter. The drive enables the variable
speed and direction component of the motor.
The drive is located in the steel cabinet mounted on the machine chassis.
As with all electronic equipment, the drives are sensitive to excessive
vibration, rough treatment and high levels of dust. Much care and atten-
tion has been given by SASE to ensure maximal protection is given to the
drive. Note the shock absorbing mounting system used to mount the
steel cabinet on the machine chassis/frame.
When transporting, it is important to ensure the machinery is properly
secured at all times to eliminate “bouncing” of the variable speed drive.
Ensure the chassis or frame section of the machine is secured down at
all times when in transit.
The machine should always be transported under cover limiting the ex-
posed to natural elements – in particular rain and snow.
WARNING
The machine should not be lifted by handle, motor, chassis or other
parts. Transportation of the machine is best done on a pallet/skid to
which the machine must be firmly secured.
Do not attempt to slide the tines/forks from a fork lift under grinding
heads unless on a pallet/skid.
Failure to do so can cause irreparable damage to grinding heads of
machine and internal parts.
IMPORTANT!
It is recommended that machinery be transported with a set
of diamonds attached at all times to ensure protection of
locking mechanism for diamond plates.
Storage
The machine should always be stored in a dry place when not in use.

Setup and Operation
Planetary rotation direction
The correlation between FWD/REV & Clockwise/Counter clockwise rota-
tion can be said as follows if looking at the grinding discs from under-
neath the machine:
 REV-Clockwise.
 FWD-Reverse.
As mentioned earlier, when the machine is in operation it will pull to one
side. The direction of pull is determined by the planetary head direction
of rotation. The head of the machine will pull to the right (and therefore,
will be felt on the right hip of the operator) when the planetary head is
set in the REVERSE direction.
This sideways pull can be very useful when grinding, particularly along a
wall. Set the machine so that it pulls towards the wall, and then control
the machine so it can just touch the wall. This will ensure a grind close
to the wall or object.
Direction is also a matter of personal preference, however to improve the
cutting efficiency of diamonds, change directions on a regular basis. This
will work both sides of the diamond crystals, keeping the abrasives as
sharp as possible by creating maximal exposure of the diamond crystal.
Once both a speed and direction have been nominated, switch on dust
extraction or vacuum device.
IMPORTANT!
It is highly recommended to use a SASE BULL 1250 Industrial
Vacuum system for complete dust control.


Changing of Diamonds
Different applications often require different selections of diamond
tooling. There will be many occasions when the grinding discs need
to be changed.
Following is a guide for this procedure.
Preparation
Press the Stop button and engage the Emergency Stop button.
As an extra precaution, unplug power cord to prevent unintentional
starting of the machine while changing disc, which could result in
serious injury.
WARNING
It is highly recommended to have a set of gloves ready, as diamonds
can get very hot, especially during dry grinding applications.
Changing
1.Set handle in upright position (Illustrated upper right).
2. Pull back on handle to lift grinding head off the ground (Illustrated
middle right).
3. Lay machine back on the ground (Illustrated bottom right)
4. Put on gloves.
5. Remove grinding disc from flex plate.
6. Check to ensure that all discs are secure.
7. Once new diamonds have been attached, reverse procedure to lower
machine to ground.
8. As new diamonds may be a different height than the set being previ-
ously used, re-adjust skirt to ensure good seal is established with the
floor.

Determining Diamond Selection
Diamond Background
Diamond abrasives usually consist of 2 components:
 Diamond powder (also known as diamond crystals or grit). By chang-
ing the size of the diamond powder or grit, we can change how
coarse or fi ne the scratches will be that are left behind from the
grinding process.
 A binding agent (metal or resin). Diamond powder is mixed and sus-
pended in either a metal or resin binding agent. When suspended in a
metal bond matrix, the finished product is referred to as a Metal Bond
or Sintered diamond segment. When suspended in a resin bond ma-
trix, the finished product is referred to as a Resin Bond diamond seg-
ment or pad
General Diamond Principles
Diamond Grit Size:
Changing the size of the diamond grit to a smaller particle/ grit size will
affect the performance of the diamond tool in the following ways:
 Create a finer scratch pattern.
 Increase the life of the diamond tool.
The opposite will occur when changing to a larger particle/grit size.
The Binding Agent/Metal Bond or Resin Bond:
Increasing hardness of bond will:
 Increase life of diamond tool.
 Decrease production rate.
 Cause diamond tool to leave finer scratches in dry - grinding
applications (when compared to a softer bond diamond tool with
the same diamond grit size).
A hard bond matrix should be used on a soft floor and a soft
bond matrix should be used on a hard floor.
Grinding disc set-up
The set-up of diamond segments on the grinding heads of the machine will
influence the performance of the machine, the productivity levels and also
the finished floor quality.
There are basically two types of diamond configurations that can be used
when grinding:
1. Half set of diamonds – when there are diamonds placed at three
alternating positions on the diamond holder discs. ( See pictures
on upper right).
2. Full set of diamonds – when there are diamonds placed at each
of the six positions on the diamond holder discs.
(See pictures on middle right).
