------ WARNING! ------

Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin.

At operating temperature, the engine coolant is hot and under pressure.

Steam can cause personal injury.

Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand.

Remove the fill cap slowly to relieve pressure.

Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.

Pressure air can cause personal injury.

When using pressure air for cleaning, wear a protective face shield, protective clothing and protective shoes.

The maximum air pressure must be below 205 kPa (30 psi) for cleaning purposes.

For your own safety and maximum service life of the machine, make a thorough walk-around inspection before mounting the machine to start the engine.

Look around and under the machine for such items as loose bolts, trash buildup, oil or coolant leaks (Perkins Engine), broken or worn parts. Inspect the condition of the implements and the hydraulic components.

1. Inspect the implements for damage or excessive wear. Repair if damaged.
2. Inspect implement cylinders and linkage for damage or excessive wear. Repair if damaged.

3. Inspect and replace lights, broken bulbs and lenses.

4. Remove trash buildup in and around the engine.
5. Inspect and repair any cooling system or engine component leaks.

6. Inspect the engine precleaner screen for dirt buildup, and clean with pressure air when there is accumulation.

7. Inspect steps and handholds for condition and cleanliness. Repair or clean if necessary. Inspect the Falling Object Protective Structure (FOPS) (if equipped) for damage. Tighten any loose bolts. Repair if necessary.

8. Inspect and repair any hydraulic system leaks.
9. Inspect and repair any axle leaks.

10. Be sure covers and guards are firmly in place. Inspect for damage.
