1. INTRODUCTION

These instructions cover the procedure for installing

the replacement parts contained in the retrofit kits

onto the hydraulic handle control assemblies used

with the heavy duty hydraulic pumps listed in Figure

1. The retrofit kit is designed to replace the existing

trigger and micro--switches on the handle control

assembly as well as the mounting hardware.

3. RETROFIT PROCEDURE

The retrofit procedure requires an understanding of

electrical wiring and soldering technique. It is

recommended that this retrofit be made by a skilled

technician in an environment that allows it to be

completed on a workbench.

Reasons for reissue of this instruction sheet are

provided in Section 4, REVISION SUMMARY.

3.1. Disassemble the Handle Control (See Figure 1)

1. Clean the handle control with a soft cloth and a

suitable solvent or cleaning fluid which will not

harm paint or plastic material.

2. DESCRIPTION

The following replacement parts are included in each

retrofit kit.

2. Remove the quick--coupler (part number

311470--1 or 311471--1) and lay aside.

— two of Slotted Head Screw 5--21016--6

(10--32¢.38--in. long screws)

3. Remove the strain relief from the wire as it

enters the handle tube by carefully grasping it with

a pair of needle--nose pliers and pulling it out of the

opening. Take care not to pinch or cut the wire

insulation.

9. Discard the switch cover, trigger, switch

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

faceplate.

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.

3.2. Assemble the Retrofit Kit (Figures 2 and 3)

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).

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:

6. Remove two screws securing the faceplate and

discard.

1. Place the conductors through the circular

opening of the switch cover.

7. Remove the faceplate and switch base (retain

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

2. Pull the WHITE conductor through the opening

marked RUN.

3. Pull the BLUE and ORANGE conductors

through the opening marked DUMP.

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

remove the micro--switches, switch mounting plate,

trigger, and switch cover.

4. Pull the RED and BLACK conductors through

the opening marked RESET.

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.

NOTE

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).

The BROWN wire is a jumper between the RUN

be pulled through the two openings to allow easy

soldering, substitute it with a length of 0.5mm²

switch itself but will provide an even distribution of

pressure on the switch housing) and press--fit the

switches into their respective openings. Take care

to align the beveled portion of each switch housing

with its identifying marking on the switch cover.

NOTE

7. Solder the switches:

Take care to ensure that there are no wires in

contact with the housing.

CAUTION

a. Obtain the GREEN switch and solder the

WHITE conductor to one of the solder tabs and

the BROWN jumper to the other solder tab.

11. Install the guard to the switch cover and

secure it with the two slotted head screws provided

with the retrofit kit.

b. Obtain the RED switch and solder the BLUE

conductor to one of the solder tabs and the

ORANGE conductor to the other solder tab.

c. Obtain the YELLOW switch and solder the

BLACK conductor to one of the SQUARE

solder tabs and to one of the ROUND solder

tabs. Solder the BROWN jumper to the other

SQUARE solder tab. Then solder the RED

conductor to one of the ROUNDED solder tabs.

12. Carefully slide the switch assembly back onto

the handle tube and secure it with the two screws

removed in Step 3 of Paragraph 3.1.

13. Apply pipe sealant to the threads of the handle

tube and replace the quick--coupler.

NOTE

can be best accomplished by stripping enough

insulation from the wire to thread the conductor

through the holes in the two tabs (thereby

commoning them on the conductor) and then

soldering them.

8. Check the wiring connections for correct

placement and solder joints.

9. Reconnect the green wire (with the ring terminal

crimped on it) to the tube handle using the 4--40

screw and washer.
