Check the coolant level in radiator sight glass to make sure coolant is present.

If coolant must be added, remove radiator cap by turning it to the left or counterclockwise up to the safety stop until all pressure is released. Press down on the cap and continue to turn until the cap is free to be removed.

Add fluid until visible in sight glass.

CHECK ENGINE CRANKCASE OIL LEVEL

Stop the engine and check level. For an accurate reading wait for the oil to drain into the crankcase pan. Open hood access door. Remove the oil level gauge (1) and wipe it clean. Reinsert the gauge completely. Remove the gauge and check the oil level. If the level is at or below the ADD mark, add oil through the filler opening (2) to bring the level up to the FULL mark on the gauge.

CHECK EQUIPMENT SYSTEM HYDRAULIC OIL LEVEL

With the oil at operating or ambient temperature, park the machine on level ground, lower the blade to the ground, release the control lever and stop the engine.

Check oil level at sight gauge on the side of the reservoir. Add oil if level is below the center line of the gauge.

24.12.1 GENERAL: Proper maintenance and mechanical efficiency is enhanced during seasonal air temperatures changes, when the following instructions are followed.

24.12.2 OUTSIDE SOURCE OF HEAT: Machines left outside for prolonged periods in sub-zero weather will suffer from cold-soak. Lubricants become viscous and incapable of lubricating moving parts.

Is there a source of outside heat available for the machine?

24.12.3 LUBRICATION: Lubricate and service your machine at intervals specified in 23.1 MAINTENANCE SCHEDULE CHART.

Have you selected oils and lubricants specified at Anticipated Air Temperature for seasonal preparations?

24.12.4 FUEL SYSTEM: For details of the fuel to use, see 20.1 PROPER SELECTION OF FUEL, COOLANT AND LUBRICANT.

24.12.5 COOLING SYSTEM: Prepare the cooling system as follows:

Check the entire system for leaks.

Inspect the condition of all hoses and replace the hoses and hose clamps as necessary.
