The fuel gauge assembly is a fixed component of the left
handle halve (43). Connect the five wire terminal block to
the corresponding five wire port on the PCBA.
Place POP Switch (63) into top slot of left handle halve.
Be sure that the ‘2’ is positioned to the back of tool.
Route the four wires through the channel along the
inside wall as shown. Trap the wires in place using
two Rubber Slugs (28). Carefully place all components
of the Electronics Assembly (62) into the handle halve.
Connect the four wire terminal to the port on PCBA (34).
NOTE:
It is very important to make
sure that wires are tucked down

wires being pinched when
re-assembling tool.
Be sure that all elements of
the Electronics Assembly
(On-Off Switch, PCBA,
LED, Terminal Block
Connector and Stator)
are properly seated into
the left handle halve
before re-assembly.
When installing the Fwd/Rev
Shuttle, be sure to properly
capture the slide button of
the fwd/rev micro switch
on the PCBA with the
front cavity of the shuttle.
Once in the left handle halve,
be careful that no wires
interfer with the travel of the
Fwd/Rev Shuttle.
