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.
