Check all fluids daily. Engine must be cold and on a level surface.

.This unit has a low oil pressure shutdown switch. However, some conditions may cause engine damage before the en- gine shuts down. Check oil lev- el often and do not use the oil pressure shutdown system to monitor oil level.

1Carburetor Heat Selector Pipe

2Manifold

Turn pipe toward manifold in cold weather and away from manifold in warm weather.

3 Fuel

Add fresh fuel before starting engine the first time (see mainte- nance label for specifications). Fill fuel tank up to 1/2 in. (13 mm) from top to allow room for expansion. Open fuel shut-off valve. Check fuel level on a cold engine before use each day.

4 Oil

After fueling, check oil with unit on level surface. If oil is not up to full mark on dipstick, add oil (see main- tenance label).

5 Coolant

Add coolant if level is below bottom of radiator filler neck.

Engine coolant is a mixture of water and ethylene glycol base anti- freeze. Add anti-freeze to mixture if using unit in temperatures below 0° F (–18°C).

Keep radiator, air intake, and cool- ing fins clean and free of dirt.

YIncorrect engine tempera- ture can damage engine. Do not run engine without a

properly working 180° F (80° C) thermostat and a 7 psi (48 kPa) radiator cap.

.To improve cold weather starting:

Keep battery in good condition. Store battery in warm area off concrete surface.

Use correct grade oil for cold weather.
