Page 5: Basic Structure
BASIC STRUCTURE K3000 Husqvarna's electrically driven power cutters are based on a common motor unit that allows wet cutting with a limited amount of water. The machine versions are shown in the illustration below. The workshop manual deals with the motor unit in a common section and the distinct parts for each machine in a chapter for each type of machine. -
Page 6: Carbon Brushes
CARBON BRUSHES Replacing the carbon brushes The two carbon brushes transfer electric current to the motor's rotor. The carbon brushes are wear parts that must be checked regularly; every week if the machine is used daily. You should replace the carbon brushes when around half is left. You can easily measure this using a slide gauge without removing the brushes. -

Page 10: Testing - Electrical Components
TESTING – ELECTRICAL COMPONENTS Work procedure The electrical function is checked in the following chapter exclusively with a multimeter. No checks are made with the machine connected to the mains! The only exception is the function check of the earth fault breaker that is done without the machine or earth fault breaker being dis- mantled. -
Page 11: Electrical Cables, Contacts
ELECTRICAL CABLES – CONTACTS Test of mains cable The earth fault breaker does not allow the current to pass this when it is not connected to the mains supply. In order to check the mains cable with a multimeter, the earth fault breaker ends must be pulled apart to access the connection points. -
Page 12: Rotor
ROTOR Functional test Preparations Remove the inspection cover to the carbon brushes. Connect a measuring cable to each carbon brush. (You do not need to be concerned that the stator is connected at the carbon brushes as the stator's circuit board is broken at the circuit board and is therefore not affected by the measurement.) Measuring cables Use short measuring cables and lay these close to each other: the easiest way is... -

STATOR – 230 V Functional test Fractures to the stator winding are easiest to indicate using the check below. In general, short-circuited windings can also be identified, particularly if the short circuit eliminates current in several winding turns. If the short circuit only eliminates a few turns, the measurement is unlikely to record this. -

Page 31: Wet System
WET SYSTEM Water coupling with flow control The water coupling with flow control is identical for all K3000 with wet systems. The water coupling is adapted to suit the Gardena® system. The coupling in the machines for wet cutting have a flow control that regulates to a virtually constant flow at varying water pressures. - Page 32 WET SYSTEM K3000 Wet Construction A spray nozzle is located on each side of the blade guard. The water strikes a section of the cutting blade and the centrifugal force carries it out towards the blade's diamond segments. The spray nozzles have a smaller diameter for the water spray compared to the petrol-driven cutters in order to restrict the amount of water.
