(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 : β’ Model, machine number, operation hours β’ Reasons for repair, history of repair β’
Contamination of filters β’ Fuel and oil condition β’ 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.
