1. General

The adjustments and test procedures presented below are required after major repairs, parts replace-
ment, or long storage.

2. Testing the Generator Set

Test values listed below will result when the generator set is operating properly. If your test results are not
within the limits shown, perform the applicable troubleshooting procedures given in Chapter 3.
If major repairs have been made or if critical components have been replaced, make sure that the applica-
ble adjustments have been made before testing the generator set. Adjustment procedures are described
in Para. 3 of this Section.
A. Preoperational Test Procedures
(1) Open engine compartment door 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.
(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, obvi-
ous shorts, etc.

REASON, REFER TO ADJUSTMENT PROCEDURES IN PARA. 3 BEFORE TESTING GENER-
ATOR.
