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 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 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 whenmaking 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.
