SAFETY PRECAUTIONS

MAINTENANCE AND REPAIR

• When lifting parts or assemblies, make sure all slings, chains, or cables are correctly

fastened, and that the load being lifted is balanced. Make sure the crane, cables, and
chains have the capacity to support the weight of the load.

• Do not lift heavy parts by hand, use a lifting mechanism.

• Wear safety glasses.

• DISCONNECT THE BATTERY CONNECTOR before doing any maintenance or repair

on electric lift trucks. Disconnect the battery ground cable on internal combustion lift
trucks.

• Always use correct blocks to prevent the unit from rolling or falling. See HOW TO PUT

THE LIFT TRUCK ON BLOCKS in the Operating Manual or the Periodic Mainte-
nance section.

• Keep the unit clean and the working area clean and orderly.

• Use the correct tools for the job.

• Keep the tools clean and in good condition.

• Always use HYSTER APPROVED parts when making repairs. Replacement parts

must meet or exceed the specifications of the original equipment manufacturer.

• Make sure all nuts, bolts, snap rings, and other fastening devices are removed before

using force to remove parts.

• Always fasten a DO NOT OPERATE tag to the controls of the unit when making repairs,

or if the unit needs repairs.

• Be sure to follow the WARNING and CAUTION notes in the instructions.

• Gasoline, Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), and Diesel fuel

are flammable. Be sure to follow the necessary safety precautions when handling these
fuels and when working on these fuel systems.

• Batteries generate flammable gas when they are being charged. Keep fire and sparks

away from the area. Make sure the area is well ventilated.

NOTE: The following symbols and words indicate safety information in this
manual:

General

This service manual provides the electrical diagram
for YardMasters

with a optional 7-function joystick

and instructions how to convert from a 5-function joy-
stick to a 7-function joystick.

On YardMasters with a 5-function joystick, the pow-
ered pile slope function is activated by a separate
switch on the right-hand side panel. The additional
two buttons on a 7-function joystick allows activating
the powered pile slope function without releasing the
joystick.

The electrical diagram for rotation, 40 liter (10.6 gal)
hydraulic flow, and sideshift function are similar
with those in the section Diagrams, YardMaster

8000 SRM 784. The difference is, that in the dia-
grams for the 7-function joystick, the switches S142
to S148 have been provided with numbers (1 to 7) in
rectangular boxes, that refer to the legend numbers
of the 7-function joystick buttons.

See Figure 1.

Figure 2 shows the wire locations of the joystick
connector PMH7B.

agrams, YardMaster

shows how to disconnect the pile slope switch (S96),
that is to be made redundant.

Conversion

2200 SRM 1204

Conversion

These instructions describe the conversion from a
5-function joystick, to a 7-function joystick.

The

required parts are available as a kit, part number
1592833. The kit consists of the following:
• 7-function joystick
• Joystick wire harness

Remove connector PMH from the 5-function joy-
stick.

Remove the 5-function joystick and replace with
the 7-function joystick.

Remove the connection from the separate pile
slope switch by cutting the wires 644, 15, 208,
and 209 at a distance of about 100 mm (4 in.)
from connector CTGD. Related connector num-
bers are 2, 7, 1, and 3.

Isolate the wires at the switch side.

Plug connector PMH7B of the wire harness into
the plug of the 7-function joystick. The layout of
the wire harness is shown in Figure 3.

Connect the previously cut wires 644, 15, 208,
and 209 on the harness side (location SCTGD)
with the wires with the same number coming
from wire harness. Isolate with red shrink tube
hose.

Insert connector PMH from the side console har-
ness into connector PMH of the joystick harness.

Mount the two relays at the inside of the side
panel.

Start the engine and check correct operation of
the joystick switches.
