- Correct work means the quickest possible completion of according to the correct procedures and the specified standards.
- It is important when conducting certain operations always to bear in mind the equipment, tools, gauges, materials, oil and grease, etc. that you must have ready, as well as items to be checked, adjusted, or disassembled, and cautions to watch out for.
- (1) Never attempt servicing while engine is running or immediately after stopping operation. (2) Wear work cloths, safety shoes and helmet. (3) Check the equipment and tools before use. Especially, be sure to check the crane, lifting equipment and tools.
- (4) When working together with other persons, allocate everyone’s share of job, arrange the signals and act in concert with the other persons. (5) The operation of the crane and slinging work must be performed by qualified persons.
- (6) Do not enter or pass under the raised load. (7) Lift and support the massive parts by crane before removing the installation bolts. (8) Disconnect cables from battery before repairing the electric system.
- (9) Remove the battery when welding the machine. (1) Check the service record of the machine. (That is, check how many months or hours the machine has been used since the preceding overhaul, what was the trouble then and what parts were replaced.)
- (2) Have all servicing tools ready, i.e., tools, measuring devices (which have received periodic maintenance), containers, oil & grease, etc. (3) Have the service literature (operation manual, parts catalog, etc.) ready.
- (1) Clean the machine before disassembly. (2) Check and record the condition of the machine before disassembly : • Model, machine number, operation hours • Reasons for repair, history of repair •
- Contamination of filters • Fuel and oil condition • Damage to parts, etc. (3) Place alignment marks on the necessary parts to facilitate reassembly. (4) Clean all the removed parts and new replacement parts and put them in order. (5) Use new seals, split pins, etc. for reassembly.
