Husqvarna PG820 - Manual (Page 24)

26 - English
The effectiveness of the planetary seal can be moni-
tored by the simple removal of the planetary motor
/ gearbox system by removing the four bolts shown
below.
If planetary seal is worn or needs replacement, contact
your Husqvarna Construction Products distributor for a
new planetary seal replacement kit.
If the planetary seal is working effectively, there should
be a very minimal amount of dust observed under
the cover of the machine. If there is a build-up of 5-
6mm (1/4 inch), then it is more than likely it is time to
remove the machine cover and check the condition of
the planetary seal.
