Repairs & Major Service
IMPORTANT: The warranty is invalidated if the installation tool is not identified with a relevant serial number label.
The label is positioned internally, at the base of the handle, on the left moulding, 41. When replacing the moulded
body a new label, 83, must be inserted and marked by hand with the tool's original serial number.
The moulded body assembly includes items 1, 2, 33, 41 to 45, 47, 48, 53, 54, 81 and 83. These parts are only available as
a complete Body Moulding Assembly Kit (part number 71600-99600), unless the individual part numbers are provided in the
parts list.
•
Remove and discard label 42 from the right moulding 43 to reveal the hidden screw.
•
Remove the nose tip spanner 53 and two nose tips from the moulded body.
•
Place the tool on its side and using the pozi screwdriver unscrew all eight pozi screws 45 in the moulded body.
•
Remove the right moulding 43 leaving the main internal mechanism within the left moulding 41 as shown on page 10.
•
Remove the vent screen 54, battery retainer spring 47 and dowel pin 48 from the left moulding 41.
•
Before removing the main internal mechanism ensure that the electrical control circuit 5 and the reservoir 73 are released
from the mounting points within the moulding.
•
Holding the tool by the motor and gearbox assembly 3 remove the main internal mechanism from the moulding.
Assemble in reverse order to dismantling noting the following points:
•
Place the main internal mechanism into the left moulding 41, first ensuring that the electrical control circuit 5 and the
reservoir 73 are correctly placed within the mounting positions provided. The circuit board must be positioned so that the
heat sink is facing forward and the black and blue wires are at the top. The contact holder 4 must be positioned with the
positive symbol in the left moulding 41 as shown in the diagram below.
•
The contact holder is designed to enable correct orientation in the mouldings. Care must be taken to ensure that the raised
portion on the right moulding 43 fits within the indent on the negative side of the contact holder 4.
•
When replacing the right moulding 43 take care to ensure that no wires are trapped and correct alignment with the electrical
control circuit 5 and the vent screen 54 are achieved.
•
When the moulded body is fully assembled with all eight pozi screws 45, insert new case label 42 on the right moulding 43.
IMPORTANT: Correct orientation of the contact holder 4 must be achieved when assembling into mouldings 41 and
43. Incorrect assembly will cause short circuit and failure of electrical control circuit.
