Introduction
Introduction
The Husqvarna PG 530 fl oor surfacing machines are
designed for wet or dry grinding of marble, terrazzo,
granite and concrete. Their applications range from
rough grinding through to a polished fi nish.
This manual covers the Husqvarna PG 530 series of
fl oor grinders equipped with twin motor drive here after
referred to as Dual Drive Technology™.
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 have received the necessary
education, both practically and theoretically
concerning their usage should operate the
machinery.
IMPORTANT!
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 fi rmly 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.
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.
Transportation
The machine comes equipped with inbuilt advanced
electronic systems called variable speed drives or
frequency converters. These drives enable the variable
speed and direction component of each of the motors.
The drives are 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 attention has been given
by the manufacturer to ensure maximal protection is
given to the drives. 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 drives. 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 exposed to natural elements – in
particular rain and snow.

What is what
The machine can be divided into two main parts. These
can be identifi ed as follows:
IMPORTANT!
1. Chassis/Frame section – comprising handle bars,
electrical cabinet, steel frame and wheels.
2. Head – comprising of motors, cover, grinding/satellite/ planetary heads and internal components.
The machine has been manufactured to allow movement between the chassis and head via the connection
point at the lifting lugs and chassis pins. This movement is important during the grinding process as it
creates a “fl oating” effect for the head.
The fl oating gives the head a self-leveling effect, negat-
ing the need to adjust the height of the head as the
machine passes over fl oor areas with different slopes
or undulations.
Control panel
The control panel consists of a number of switches and
dials giving 6 separate controls (see picture).
Power - This button, when depressed, will turn on
power supply to the unit when the EMERGENCY
STOP button has been released.
Planetary head and grinding heads are set
to both turn in the same direction (i.e. both in
clockwise rotation or both in counter-clockwise rotation).
Clockwise rotation of speed control will increase speed of planetary head and grinding
heads.
Grinding satellite/ heads
Planetary head
Emergency Stop - When pushed will immediately
shut down machine by totally stopping power supply to
drives/ frequency converters in electrical cabinet.
Disc Speed - Speed control for grinding heads and
planetary head.
Fwd/Rev (Red) - Direction control for grinding heads
and planetary head.
Reset - Will clear fault function/error message on drive/
frequency converter (located in electrical cabinet) in
case of fault occurring.
Stop/Run - To start or stop machine during normal
operation.
IMPORTANT!
It is important to use the STOP/RUN switch
to control the running of the machine, not
the EMERGENCY STOP button. Each time
the EMERGENCY STOP button is pressed
it shuts down the drive/frequency converter.
Frequently powering up and down of the
drive/frequency converter will reduce the life
span of the drive/ frequency converter.

Setting up/Operation
Setting up/Operation
Powering up machine
i. Ensure the STOP/RUN switch is set on STOP
(rotate counter clockwise).
ii. Plug power supply to machine. Only turn power on
at
plug once fully connected.
Position grinder on the working area. Make sure there
are diamonds underneath machine and that the head
locks/shear pins are tight.
IMPORTANT!
When using the machine, each grinding
head must always have the same diamond
type and number of diamonds as the other
grinding heads. Each grinding head must
have diamonds the same height as the other
grinding heads.
Adjust rubber skirt so that a good seal is established
between the fl oor and head of machine (see picture
below). Ensure join in skirt is at the front of the machine. Setting of the skirt is essential to obtain good
dust extraction and eliminate the possibility of airborne
dust when dry grinding.
iii. Disengage Emergency Stop button (twist clockwise).
iv. Depress Power button. On doing so, a soft “clunk”
should be heard to come from within the electrical cabinet. This indicates the line contactors have engaged,
supplying power to the drives/frequency converters.
Setting Speed and direction
On the control panel there is a FORWARD/REVERSE
and Speed dial knob. Generally, when starting the
machine for the fi rst time on any given application, it is
advised the speed setting should not exceed 7, initially.
When the operator is comfortable with the application,
speed may be increased.
IMPORTANT!
It is important to note the following when
using the Husqvarna PG 530 single-phase
grinder:
Set handle to most comfortable working height using
adjustment lever.
IMPORTANT!
It is recommended that this height be set as
close as possible to the height of the operators hip bone.
When the machine is running, there will be a grinding force/pull to one side that can be felt through the
handlebars. Use the hip to resist this force instead of
trying to control this through the arms (such positioning
will be much easier for the operator using the machine
over prolonged periods of time).
Increasing the speed will also increase the
current being drawn by the machine.
If on some applications the machine is drawing too much current and tripping current
limiting switches, the speed of the machine
must be reduced to compensate.
Low voltage supplies to the grinder may result in poor performance (reduced speed and
torque) of the machine.
Factors which may contribute to low voltage
supply to the machine include the following:
- Poor mains power supply (below 220V).
- Working off a generator.
- Using light duty power leads (power leads
with at least 2.5mm cores are highly recommended).
- Using more than 20m (65ft) long power
lead.
