☞ Stop the engine.
☞ Raise the control lever base.
☞ Remove the starting key and carry it with you.
☞ Disconnect the battery or the battery master switch.
☞ Open the engine cover.
☞ Let the engine cool down.
☞ Carefully check V-belt 1 for damage, cracks or cuts.
➥ Replace the V-belt if it touches the base of the V-belt groove or if the pulleys are
damaged.
☞ Press with your thumb about 100 N (22.5 lbs.) to check the deflection of the V-belt
between the crankshaft disk and the fan wheel. A new V-belt should have a deflection
of 6 to 8 mm (0.24 to 0.31 in), a used V-belt (after about 5 minutes running time)
should have a deflection of 7 to 9 mm (0.27 to 0.35 in), see fig. 199/2.
☞ Retension the V-belt if necessary.
• If the V-belt is damaged:
☞ Have the V-belt replaced by authorized personnel.
