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 instructions 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 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:
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 background. The CAUTION symbol and word are on yellow background.

Drive Axle Removal WARNING When putting the lift truck on blocks, make sure the surface is solid, even, and level. Any blocks used to support the lift truck must be solid, onepiece units. 1. Put blocks on each side (front and back) of the steering tires to prevent movement of the lift truck. 2. Raise the lift truck and put blocks under the frame so that the drive wheels do not touch the floor. Put blocks under the counterweight for stability. 3. Remove the mast assembly as described in the section Mast Repairs (S/N A513, A514, A613, A614, A702, A703, A704, A705, A706, A707, A751, A752, B513, B514, B586, B587, B588, B589, B590, B591, B749, B750, B751, B752, B753, B754) 4000SRM1250.
or death. Never loosen nuts that hold together inner and outer wheel halves when there is air pressure in tire. 4. Remove the wheels. 5. Remove the planetary carrier housing fill/level plugs on both sides of the drive axle. See Figure 2 for lift truck models •
See Figure 3 for lift truck models •
On lift trucks with pneumatic tires, completely remove air from tires before removing them from lift truck. Air pressure in tires can cause tire and rim parts to explode, which can cause serious injury

CAUTION If the rolling torque exceeds the maximum value, then the size of the calibrated spacer (8) S2 between the bearing (7) and distance spacer (11) needs to be increased. See Figure 12. If the rolling torque does not reach the set value, increase the torque setting of the ring nut in different stages to obtain a maximum value of 500 N•m (369 lbf ft).
CAUTION If the rolling torque does not reach the minimum value, then the size of the calibrated spacer (8) S2 between the bearing (7) and distance spacer (11) needs to be decreased. See Figure 12.
