FIG. NOTES
123 Prior to taking tool apart, use a sharp razor blade to score the center
line of nameplate. This will allow housing halves (16 and 20) to
separate when housing screws are removed.
123 A clean, dry surface is essential for the proper performance for any
adhesive system. The area intended for application of any adhesive
label or nameplate must be prepared by cleaning with isopropyl
alcohol. The solvent is to be applied with a clean, lint free applicator
and the surface allowed to dry before applying any label or nameplate.

1. Route Trigger Switch wires in wire traps as shown. Be sure to push
wires completly down in traps. Place trigger ribbon cable in cable
channel and secure with foam tape. Install Trigger Switch rmly and
squarely in switch cavity of the Power Head Housing Support.
2. Prior to installing the Electronics and Gearcase Assemblies, continue
to route trigger ribbon cable through cable channels of Power Head
Housing Support. Be sure the ribbon cable is pressed at in channel,
(Not lifting onto ribbed sur faces causing wire pinching). Secure the
trigger ribbon cable with foam tape as shown.
3. Place Electronics and Gearcase Assemblies into Housing Support.
Route Trigger Ribbon and Ground Wire through the wire traps shown,
being sure wires are fully seated in wire traps and are not falling out.
4,5 Photos depict components of the electronics package (See page 5).
Install all components rmly and squarely in corresponding cavities of
the Power Head Housing Support. Route all wires as shown being
sure those placed in wire traps are pressed completly down in bottom
of traps. Tuck all excess wires down into handle cavities to avoid
pinching when the Power Head Housing Cover is installed.
As an aid to reassembly, take notice of wire routings and position in
wire guides and traps while dismantling tool.
Be sure that all components of the electronics assembly are seated
rmly and squarely in housing recesses.
Avoid pinched wires, be sure that all wires and sleeves are pressed completely down in wire traps.
Prior to securing housing cover onto the housing support, be sure that there are no interferences.
Before installing the battery, check for proper functionality of shuttles, buttons and triggers.
Install battery and depress switch trigger to assure tool is operating properly.
