10.1 WASHER FLUID REFILLING
Open the filler neck cap and had regular
windshield washer fluid as required. The tank
has a capacity of 10 liters (2.6 US gallons). You
may use water or windshield washer fluid as well
but, during cold weather days, use windshield
washer fluid suitable for freezing temperature
only.
10.2 WASHER NOZZLES ADJUSTMENT
To avoid waste of washer fluid, assure the fluid
jets are properly aimed. Adjust nozzles so they
aim as described in Figure 33. Align the jet
adjustment tool #800377 with the reference line
shown on the front view detail. As seen on the
side view, position the adjustment tool vertically
for proper aiming.
CAUTION
Because they are made of plastic, firmly
tighten nozzle and bulkhead fittings by
hand only.
