FIRE EXTINGUISHERS
Inspect fire extinguishers monthly to insure
operation in emergency situations.
On extinguishers with a pressure gauge, the
needle should be in the green or NORMAL
range. Refill or replace extinguisher if pressure is
below normal;
Check that seal on handle is intact;
Check that hose nozzle is in good condition and
the nozzle is free of obstructions;
Keep fire extinguishers clean.
FUEL FILTER/WATER SEPARATOR
The optional fuel filter/water separator installed
in the engine compartment is used to prevent
water from entering the fuel system. The water
separator should be drained periodically or when
the telltale light on the dashboard illuminates. To
drain water, loosen the drain valve below the
separator one quarter turn. Close the drain valve
when finished.
