Introduction
Introduction
The Husqvarna PG 680/820 floor 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 finish.
This manual covers the Husqvarna PG 680/820 series of floor 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.
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 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 irrepa- rable 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 pro- tection of locking mechanism for diamond plates.
Storage
The machine should always be stored in a dry place when not in use.
