Page 189: Transporting
TRANSPORTING TRANSPORTING BY ROAD When transporting the machine on public roads, be sure to first understand and follow all local regulations. • For transporting using a trailer, check the width, height, length and weight of the trailer when the machine is loaded.
Page 190: Transporting
TRANSPORTING Loading/Unloading CAUTION: Pay attention to the following points. • Steering on a ramp is hazardous. Never attempt to steer the machine on a ramp. Personal injury or death may result due to loss of machine stability. If the travel direction must be changed on a slope, move back the machine to the flat ground of flat- bed.
Page 191 TRANSPORTING TRANSPORTING CAUTION: Securely fasten the machine to the trailer flatbed with wire ropes. The machine may move back and forth and/or laterally during transportation. 1. Apply the parking brake. Slowly rest the bucket on the trailer deck or load-carrying platform. 2.
Page 192: Transporting Wheel Loader (Urgent Situation)
• Recommended tire pressures and traveling speeds may vary depending on the type of tires used and the road conditions. Consult your nearest Hitachi dealer. • Check the tire pressure before self-traveling when the tires are cool.
Page 193 WARNING: Never attempt to tow the machine if the brake system is in need of repair. Ask your nearest Hitachi dealer to repair the machine. Operate the ma- chine only after repairs is completed. Avoid towing the machine as much as possible. If the ma- chine is to be unavoidably towed, beware of the following points.
Page 194 TRANSPORTING Releasing Parking Brake WARNING: After the parking brake is released, the machine can not be stopped using the brake system, possibly creating a dangerous situation. Before re- leasing the parking brake or connecting the brake system, be sure to lock tires with wheel stoppers. CAUTION: As soon as the machine towing is com- plete, apply the parking brake.
Page 195 TRANSPORTING Procedures (HEX. HEAD 22 mm) ZW180 If the parking brake cannot be released with the parking brake knob due to a defective pump or for any other reason, manu- ally move the brake piston by using the parking brake release bolt to release the parking brake.
Page 196 • Be sure to wedge wheel stoppers to prevent the machine from moving. • Before restarting to operate the machine, consult your nearest Hitachi dealer to have the parking brake adjusted. ZW220, ZW250 1. Turn to remove parking brake cap (1).
Page 197 TRANSPORTING When the machine is impossible to travel forward and in reverse: CAUTION: Before operating the emergency valve (spool), be sure to apply the parking brake so that the machine does not start moving. Should the drive system become inoperable due to trouble in the electrical circuit such as a broken harness, refer to section 4-16 for details.
Page 198: Towing Method
TRANSPORTING TOWING METHOD CAUTION: Use wire rope having the strength more than approx. 150 % of the machine weight. • Towing from the front side of the machine When using wire ropes, be sure to attach wire ropes to the front axle. Always use soft material at the cor- ners between the front axle and wire ropes to prevent damage to wire ropes.
Page 199: Lifting Machine
• Use lifting cables and other lifting tools being free from any damage and/or aging, and having suffi- cient strength. • Consult your nearest Hitachi dealer for correct lift- ing procedures, and the size and types of lifting cable and tools.

The ROPS cab type ZW220, ZW250 and ZW310 can comply with this require- ment. Consult your nearest Hitachi. • Before operating the machine in a river, check the riverbed conditions in advance. Avoid driving the machine into a river where the riverbed is steep and deep or the stream is rapid.
Page 316 MAINTENANCE UNDER SPECIAL ENVIRONMENTAL CONDITIONS Precautions for maintenance during cold weath- er season Before the atmospheric temperature becomes down below -0° C, practice the following points. • Water and oil in the machine will freeze. • Road surfaces will freeze so that tires may slip. Keeping the above points in mind, follow the advices below: 1.
Page 317 MAINTENANCE UNDER SPECIAL ENVIRONMENTAL CONDITIONS 7. After warming up the engine, warm up the front attach- ment system. Slowly operate the control levers to move the cylinders full stroke several times. 8. Road surfaces covered with snow, especially when snow has been compacted, will become frozen.

Page 319: Storing The Machine
In case the batteries are kept disconnected for more than one month or when the batteries are reconnected, contact your nearest Hitachi dealer. NOTE Lubrication operation means that a series of operations such as drive, and loader front operation are repeated a few times after performing the warm-up operation.
Page 320: Removing The Machine From Storage
STORAGE REMOVING THE MACHINE FROM STORAGE 1. Remove grease from the cylinder rods if coated. 2. Adjust alternator and fan belt tension. 3. Fill the fuel tank. Bleed air from the fuel system. Check all fluid levels. 4. Start the engine. Run the engine at half speed for several minutes before full load operation.
Page 321: Troubleshooting
In case troubleshooting is difficult, or measures marked with * must be taken, consult the nearest Hitachi dealer. Never attempt to adjust, disassemble, or repair the hydraulic and/or electrical/ electronic parts/components.
Page 322 Faulty sensor * Replace Items with * mark: Consult your nearest Hitachi dealer. 5. Hydraulic System After the machine has been kept stowed for a long time, air in the oil may be separated and accumulate in the upper section in the cylinder, causing slow response time in opera- tion or reducing cylinder power.
Page 323 * Repair not transmit power. Broken gears * Repair NOTE: * Consult the nearest Hitachi dealer. 6. Others The machine may have a noise, excessive vibration, and abnormal smell when any trouble occurs. Always beware of the machine conditions during operation.
