a. Pre-operational Test Procedures
(1) Open engine compartment doors and inspect the interior for rags, tools, and other foreign
materials.
(2) Check engine oil level.
(3) Check coolant level.
(4) Check battery water level (if required)
(5) Check for sufficient fuel.
(6) Check drive belts. Each belt should have approximately 1/2 inch (13 mm) slack.
(7) Inspect all wiring for possible trouble spots such as loose wires or terminals, frayed insulation,
obvious shorts, etc.
(8) Check panel lights, panel light switch, and fuse.
(9) Connect cables from generator output terminals to a load bank. The output cable consists of two
single conductor cables not more than 30 feet (9 m) long. The diameter size of each of these
two cables is determined by the maximum starting current expectations:
· Use No. 2/0 cable for 600 amp. maximum starting current
· Use No. 4/0 cable for 1500 amp. maximum starting current.
