    Caution: Do not apply P-80 emulsion to the HV terminals.

  • When lowering the drive unit, do not align the rear mount on the drive unit with the mounting hole in the subframe. Instead, pull the rear mount beyond the rear subframe. This provides enough clearance for the front of the drive unit to rotate into position as the subframe is lowered.
