CHECKS AND ADJUSTMENT BEFORE STARTING ENGINE
METHOD FOR WALK-AROUND CHECK
Before starting the engine, walk around the machine and look at the underside of chassis for anything unusual
like loose bolts and nuts, leakage of fuel, oil and coolant. Also check the condition of the work equipment and
the hydraulic system.
Check also for loose wiring, play, and accumulation of dust in places that get very hot and are exposed to ex-
tremely high temperatures.
