Safety:
1. Fundamental cautions:
Servicemen inexperienced in the units of this machine should be cautious about safety operations. They must acquire sufficient knowledge about the equipment before dismounting and disassembling it. Before dismounting each component, a serviceman should read this service manual thoroughly and find out the weight of the component, then lift it by proper means.
The following are cautions to be observed all the time.
1. Before starting repairs, find out the origin of the problem. When it becomes clear that disassembly and maintenance are necessary, first of all read this manual and parts catalog and thoroughly understand the principle of operation and construction. Then carefully check and examine each portion. Don’t disassemble portions unrelated to the problem. Unless taking all possible measures before starting disassembly, new troubles or decline in performance may be induced.
The following are cautions to be observed all the time.
1. Before starting repairs, find out the origin of the problem. When it becomes clear that disassembly and maintenance are necessary, first of all read this manual and parts catalog and thoroughly understand the principle of operation and construction. Then carefully check and examine each portion. Don’t disassemble portions unrelated to the problem. Unless taking all possible measures before starting disassembly, new troubles or decline in performance may be induced.
2. Before operating the machine, oiling or repairing, read warning labels and instructions on the machine and understand the contents.
3. Wear a safety helmet and safety shoes whenever you carry out maintenance operation around the machine. Be sure to wear safety goggles when you hit the machine or its attachments with a hammer. In welding operation, wear safety gears such as leather gloves, helmet, goggles, apron and proper working clothes, but don’t wear loose or torn clothes. Take a ring and so on off your finger when you conduct maintenance or repair.
4. Park the machine on as level and hard ground as possible. Place chocks under wheels to prevent the vehicle from moving when doing maintenance on or below the machine.
5. Before starting maintenance, remove cables to the battery and allow the capacitors to discharge. Pull out the ignition key and hang a tag saying, “Don’t start the engine.” in the cab.
6. Don’t carry out maintenance while lifting the vehicle with only a jack or a hoist. Sustain the vehicle positively with blocks and so on to prevent fatal accidents, as there is a possibility that the vehicle loses its balance and falls down on a worker in a dismounting process of certain units.
7. When the working is done on a team of more than one person, make arrangements about co-operation and communication between workers beforehand. Give a sign without fault and make sure that the sign has been transmitted to other workers before starting the next operation.
8. When it is inevitable to measure oil pressure, rotational speed, and temperature for machine inspection without stopping the engine, be careful not to be caught or pinched in rotating or moving parts such as a fan, fan belt. Make sure that there is no obstruction or no person around the machine before operating it.
Foreword:
- This service manual describes the composition of the Model TT-800XXL-1 truck crane, its repair, checks and
adjustment methods and other relevant matters. Note that this service manual does not provide the information
in the separate service manuals given below. - This service manual applies to the cranes with the specification numbers given below. Check the specification
number on the nameplate of your crane. - Read the separate operation and maintenance manual and the parts catalog for repair and maintenance of the
crane in conjunction with this manual. If the parts needs to be replaced, check the disassemble units and sales
units in the parts catalog before replacing them.
