Service Interval: After the first 8 hours
Every 100 hours
Check the condition and tension of the alternator/cooling
fan belt. Replace the belt as necessary.
1. Position the sprayer on a level surface, set the parking
brake, stop the pump, stop the engine, and remove the
ignition key.
2. Check the tension by depressing the belt midway
between the alternator and the crankshaft pulleys with
10 kg (22 lb) of force.
Note: The belt should deflect 10 to 12 mm (0.39 to
0.47 inches). If the deflection is not correct, go to 3.
If it is correct, you may skip the remainder of this
procedure and resume operating the sprayer.
3. Loosen the bolts that secure the brace to the engine
and the bolt that secures the alternator to the brace
(Figure 58).
