1.
Using a PZ2 screwdriver, remove the pan-head screws that hold the front grille in place.
2.
Using a 5mm Allen key, remove the eight M6 socket-head bolts holding the drive unit in place, and keep them
safe – ensuring you have collected both the shake-proof and flat washers for each bolt. Gently lift the drive
unit out of its locating hole – please take care as it is heavy – you may also need to use a screwdriver to
carefully lever the drive unit out of its recess. Carefully disconnect the cables from the drive unit
3.
To reinstate the driver, simply reverse the above procedure. Please observe the correct polarity – red cable to
positive terminal, black cable to negative.

Replace the front grille, taking care to align the mounting holes correctly, before replacing the screws and re-
tightening.
