SAFETY PRECAUTIONS The usefulness of this machine depends entirely on the man at the controls. The operator is its brains. He must think safety and work safely.

Neatness and safety go hand in hand. Good housekeeping habits should be developed.

1. Keep the floor clean and free from oil and grease. 2. Keep the walkways clean, clear, and free from obstructions.

3. Prevent the accumulation of grease and oil around bearings and gears.

Grease and oil collect and hold grit and dirt which work into finely machined parts. 4. A clean machine is easier to operate easier to inspect - easier to service. 5. Keep hands and clothing away from moving parts. 6. Replace guards, inspection plates, access covers, etc., promptly after reason for removal is accomplished. Strip mining equipment is subject to tremendous stresses and shock loads. These stresses are thoroughly studied and considered in the design and building of Marion equipment. This machine is built with an ample reserve of powerand strength and is well fitted to meet the demands of its tasks.

However, the Marion engineers cannot foresee the conditions imposed by abuse, mismanagement and neglect. These factors are more damaging to any piece of equipment than years of continuous operation and normal wear. Care, sound judgement and reason are an economic necessity in the operation of power equipment.
