SAFETY PRECAUTIONS
MAINTENANCE AND REPAIR
•The Service Manuals are updated on a regular basis, but may not reflect recent design changes to the
product. Updated technical service information may be available from your local authorized Hyster®
dealer. Service Manuals provide general guidelines for maintenance and service and are intended for
use by trained and experienced technicians. Failure to properly maintain equipment or to follow in-
structions contained in the Service Manual could result in damage to the products, personal injury,
property damage or death.
•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 Maintenance 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 ex-
ceed 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 flamma-
ble. 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:
WARNING
Indicates a hazardous situation which, if not avoided, could result in death
or serious injury.
CAUTION
Indicates a hazardous situation which, if not avoided, could result in minor
or moderate injury and property damage.
On the lift truck, the WARNING symbol and word are on orange back-
ground. The CAUTION symbol and word are on yellow background.

General Information About Diagrams and Schematics
The chassis wiring used in these vehicles conforms
to the electrical circuit identification standard
ES-1359 and in addition to surface marked ID
circuit numbers, generally utilizes the colors that
are indicated in Table 1.
MONOTROL®, engine harnesses, wiring to sensors,
and other applications vary with respect to wire
colors.
Diagrams and schematics in this manual can be
viewed and printed in color. If not printed or
viewed in color, refer to the electrical circuit
identification located on schematic circuits. When
viewing a color version of the diagrams and
schematics, the white chassis wires are seen as
yellow. Other wires are shown in colors similar to
actual colors, i.e. tan shows as yellow. Use circuit
identification for true wire color.
Refer to Diagnostic Troubleshooting Manual
9000SRM1112 Section 9030, Group 03 - General
Maintenance and Diagnostic Data, for further
information.
