Introduction

The Husqvarna PG 680/820 fl oor surfacing machines
are designed for wet or dry grinding of marble, terraz-
zo, granite and concrete. Their applications range from
rough grinding through to a polished fi nish.
This manual covers the Husqvarna PG 680/820 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.
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 sensi-
tive 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 mount-
ing system used to mount the steel cabinet on the
machine chassis/frame.
When transporting, it is important to ensure the ma-
chinery 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.
Introduction
It is recommended that machinery be transported with
a set of diamonds attached at all times to ensure pro-
tection of locking mechanism for diamond plates.

Storage

The machine should always be stored in a dry place
when not in use.
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 irrepa-
rable damage to grinding heads of machine
and internal parts.
