4. Slide the grip sleeve approximately one--third of

the way down the handle tube. The sleeve is a

snug fit and may require some pressure to move it

down the tube.

5. Remove the two button head screws securing

the faceplate and switch assembly to the handle

tube and lay aside (they are required for

re--assembly).

6. Remove two screws securing the faceplate and

discard.

7. Remove the faceplate and switch base (retain

one of the 4--40¢.312 screws and the washer).

8. Solder the leads to the micro--switches and

remove the micro--switches, switch mounting plate,

trigger, and switch cover.

It is best if the leads are desoldered; however,

they may be cut if they are cut as closely to the

solder joint as possible. Re--assembly requires as

much lead length as possible. Otherwise, the

wrap around the hydraulic hose has to be all

removed and then replaced to slide the cable up

to the handle control to gain more working length.

9. Discard the switch cover, trigger, switch

mounting plate, micro--switches, switch base, and

faceplate.

Prior to installing the retrofit kit, the replacement parts

should be identified as well as the colors of the leads

to be soldered to the replacement switches. Use the

standard procedure for preparing leads for soldering

then proceed as follows:

1. Place the conductors through the circular

opening of the switch cover.

2. Pull the WHITE conductor through the opening

marked RUN.

3. Pull the BLUE and ORANGE conductors

through the opening marked DUMP.

4. Pull the RED and BLACK conductors through

the opening marked RESET.

5. Pull one end of the BROWN wire through the

opening marked RUN and its other end through the

opening marked RESET.

6. Retain the GREEN wire (with the crimped ring

terminal) inside the switch cover to attach later to

the handle tube (this is a ground wire).
