5.2 HOISTING MACHINE

• When lifting up the Machine, always set it to the stowage position first, and lift from the lifting bracket (A) on the top of the boom. Only use this bracket and only one sling wire. Any other manner than this, i.e. from other lifting brackets or multiple sling wires, may cause droppage of the machine and result serious injury or death. Where there is no choice but the machine has to be hoisted in a different manner, please contact us or service agencies.

• The hoisting attachments such as wire rope and shackle used in hoisting shall be sufficiently strong for the weight of this machine.

• Crane stowed position when it is hoisted means its “Travelling position” where 4 of outrigger position pins are securely inserted in the outrigger rotary. The centre of the balance of the machine is specified subject to the machine being in its travelling position. In addition, to set it into that position correctly, secure the hook block (4) to its stowing position, also tension the wire rope tight, this will prevent the boom derricking cylinder form extending. Refer to "Operation 2.5 Machine Travelling Position" for details of travelling position.

• Hoisting the machine for a long time will cause the boom derricking cylinder to extend, shifting the centre of gravity and the machine to lose balance. Thus, hoisting should be limited to a max of 10 minutes.

• Where it is required to hoist the machine for a longer time (exceeding 10 minutes), or when it is carried by a helicopter, use a proper carriage deck as shown in the diagram on the right, for safe transportation.

Caution

• When the local laws and regulations are applicable, the person who uses the crane to perform hoisting operation must be qualified to do it. If not, the operator must be well trained and skilled.

• See the Dimension or the nameplate attached to the machine for the weight of the machine.

• The dimensions are for standard specifications. The hoisting method varies depending on the attachments and options mounted. In that case, contact us or our sales service agency.

Hoist the machine on solid and flat ground using the following procedure.

1. See “Operation 2.5 Machine Travelling Position” and put the machine in the “Travelling position”

2. Verify that the position pins (four) are securely inserted in the outrigger rotary joint of the 4 outriggers

3 Hang the hook (2) directly to the bracket (A) on the top of the boom, or use a shackle (1) to hang the hook (2).

Notes

Position (A) on the top of the boom is in the centre of gravity of the machine.

4. As soon as the machine leaves the ground, stop and wait until the machine is stabilized. Then slowly hoist the machine.

5. Check the changes in the position due to the leakage from the hydraulic circuit on the head side of the derricking cylinder (4) when the machine is hoisted.

5.3 CAUTIONS IN LOADING MACHINE

Select flat and solid ground for loading/unloading the machine. Keep sufficient distance from the shoulders.

Load the machine to the specified position on the trailer and secure the machine with the following procedure.

1. Stop the engine and remove the key of the main starter switch.

2. Put rectangular lumbers at the front and rear of the rubber tracks to prevent the machine from moving, and stretch chains or wire ropes between the shackle of the machine body and trailer deck tightly, in addition. Ensure it is well secured so it does not slip to the side.

5.4 CAUTIONS DURING TRANSPORTATION

Take road width, height, and weight into consideration when determining the transportation route.

If there are applicable local laws and regulations, observe these laws and regulations for safe transportation.

If not, contact us or our sales service agency.

6. HANDLING IN COLD WEATHER

6.1 PREPARING FOR LOW TEMPERATURE

When the temperature goes down, the machine may have some difficulty in starting. Take the following actions.

[1] LUBRICATION

Change the oil to the one with low viscosity. See “Maintenance 5.1 Use of Lubricating Oil According to Temperature” for the specified viscosity.

[2] BATTERY

• The battery produces combustible gas and can be explosive. Do not put fire close to the battery.

• The battery fluid is a harmful substance. Keep it away from your eyes and skin. Should it come into contact with your eye or skin, wash the affected area with plenty of water and consult a physician immediately.

The battery capacity drops when the temperature goes down. In this condition, the battery fluid can freeze with low battery charging rate. Keep the charging rate as close to as 100%. Keep the battery warm in order to start the engine next morning.

Notes

Measure the specific gravity of the battery fluid and convert it into the charging rate using the chart below.

[3] CAUTIONS AFTER COMPLETING THE OPERATION

Observe the following to prevent the machine from not being able to function the next morning because of deposits such as dirt, water and materials being frozen around the feet.

• Remove the dirt and water on the machine.

Keep the hydraulic cylinder rod surface especially clean to prevent seal from being damaged with the dirt coming into the seal together with the water drops.

• Park the machine on solid and dry ground.

If there is no such location to park, place a board on the ground to park the machine on the board. This prevents the ground and around the feet of the machine from freezing and allows the machine to start moving next morning.

• Remove the drain plug to drain the water in the fuel system to prevent the water from freezing.

• The battery ability drops substantially at low temperature. Cover the battery or remove the battery from the machine and keep it in a warm place to be installed next morning.

• If the electrolyte level is low, refill with distilled water next morning before starting the operation. Do not refill after the operation in order to prevent the water from freezing during the night.

[4] AS THE WEATHER GETS WARMER

When the seasons change and it has started to get warmer, take the following action.

• See “Maintenance 5.1 Use of Lubricating Oil According to Temperature” to change the oil in the system to the one with specified viscosity

7. LONG-TERM STORAGE

7.1 BEFORE STORING THE MACHINE CAUTION

The machine shall take the position shown in the diagram on the right during the long-term storage to protect the cylinder rod. See “Operation 2.5 Machine Travelling Position” for travelling position. (To prevent rust on the cylinder rod)

Store the machine as described below for long-term storage.

• Wash and clean each section of the machine and store indoor.

If you absolutely have to leave it outdoors, select a flat location where the machine is not likely to be exposed to flood or other disasters and cover the machine.

• Refuel, grease, and change the oil without fail.

• Disconnect the negative terminal of the battery and cover, or disconnect the battery from the machine for storage.

• Refer to "Inspection and Maintenance 8.6 Irregular Maintenance [4] Engine maintenance for Long-term Storage" and drain all the fuels in the tank and carburetor

7.2 DURING STORAGE

If you have to perform an antirust operation indoors, open the window and doors for better ventilation to prevent gas poisoning.

Be sure to operate the machine once a month during the storage to maintain the oil film at lubricating section. Charge the battery at the same time.

7.3 AFTER STORAGE

If you did not perform antirust operation monthly during the long-term storage, contact us or our sales service agency before using the machine.

Perform the followings before using the machine after the long-term storage.

• Refuel, grease, and change the oil without fail.

• Remove the cover over the battery (install the battery to the machine if dismounted for storage). Check the electrolyte level and specific gravity, and then connect the battery cable from the positive side.

• Remove the drain plug of the fuel tank, hydraulic oil tank, and engine oil pan to drain the water mixed in.

• Carefully perform the check before starting operation and warm-up operation. Carefully check the various parts of the machine.

8. HANDLING THE BATTERY

Observe the followings when handling the battery.

• Stop the engine and turn the main starter switch to the OFF position when checking/ handling the battery.

• Wipe off the dust accumulated on the top of the battery with a moistened cloth.

• The battery produces hydrogen gas, involving an explosion hazard. Do not put fire such as cigarettes close to the battery or take any actions that can cause sparks.

• The battery fluid is diluted sulfuric acid, which corrodes clothes and skin. Should the battery fluid come into contact with your clothes or skin, wash the affected area immediately with plenty of water. Should it go into your eye, wash your eye immediately with clean water and consult a physician.

• Wear goggles and rubber gloves when handling the battery.

• Disconnect the ground side (normally (-) terminal) first to remove the battery, and conversely, connect the (+) terminal first to install the battery. Objects such as tools coming between (+) terminal and the machine body will cause sparks.

• Slackened battery terminals can cause sparks with poor contact, involving explosion hazard. Tighten securely when Installing the terminals.

• Secure the battery when changing the battery to prevent the battery from being displaced. If it is not secured, the terminals will slacken, causing sparks.

• Verify the (+) terminal and (-) terminal when removing and installing the battery.

8.1 CAUTIONS IN HANDLING THE BATTERY

• Always try to keep the battery charged. The battery should not be charged in a rush after being discharged. Measure the specific gravity of the battery fluid in advance and charge the battery as needed. Keeping the battery in the best condition lengthens the life of the battery.

• Check the electrolyte level earlier than regular check and maintenance schedule during the hot season.

• The battery performance drops substantially during the cold season. Keep the charging rate as close to as 100% and try to keep it warm for starting the operation next morning.
