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 arid 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 power and strength and is well fitted to meet the demands of its task.
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 judgment and reason are an economic necessity in the operation of power equipment.
DO
1. Carefully read this Manual and Parts Book.
2. Lubricate regularly. Establish a systematic procedure and stick to it.
3. When lubricating, check all bolts, nuts, lock nuts and cotter pins.
4. Keep loose objects in tool box or in suitable enclosure or cabinet.
5. Always replace guards.
6. Always watch your clearance when swinging.
DON'T
1. Service or lubricate parts that are moving.
2. Leave the load suspended in air.
DON 'T APPLY SWING BRAKES WIDLE MACHINE IS ROTATING, EXCEPT IN EMERGENCY.
PREVENTIVE MAINTENANCE
Open pit mining machinery is required to operate in the most adverse conditions of any industrial machines.
Conditions are rarely ideal. It is always too hot, too cold, too dry or too wet. The air is always saturated with fine abrasive dust. High production schedules tax both men and machines.
Downtime and delays are intolerable. Downtime can not be eliminated, but it can be kept to a minimum by a progressive and conscientious program of preventive maintenance.
