This manual is provided for the guidance of all persons who operate, lubricate, adjust or maintain the M-II Blast Hole Drill. The information was prepared with the purpose in mind of furnishing accurately and concisely all of the data necessary to the operation and service of this machine.
PARTS BOOK
This manual is not a parts book and should not be used in ordering parts.
You have been furnished with a detailed parts book which lists all parts by group number with item number and part number for your specific machine.
When ordering parts, it is necessary that the following information accompany each order:
Type Serial Number Item and Part Number Group or Repair List Number
Be sure that the serial number of the drill is given in any letter, telegram or other communications.
If this number is available, the design and original equipment can be quickly and accurately checked.
The serial number of the machine will be found on a name plate inside the operator's station.
RIGHT AND LEFT HAND PARTS
The front of the drill has been arbitrarily established at the power cable entrance. The drill table and control station is at the rear. The right and left hand parts designated correspond to the operator's right and left hand when facing toward the front or when facing the control panel.
If further information is required which is not found in this manual, or in the parts book, communicate with the Marion Power Shovel Company, located in Marion, Ohio.
No charge for service or labor are accepted unless work has been previously authorized by the Company in writing.
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 inspecteasier 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.
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.
Down time and delays are intolerable. Down time can not be eliminated, but it can be kept to a minimum by a progressive and conscientious program of preventive maintenance.
Aside from regular lubrication, proper and accurate adjustments, the personnel should be aware of any deviation from the normal, which could be evidence of impending break down or component failure.
The maintenance people should inspect, during their rounds, structural members for evidence of cracked, broken or loose parts. Evidence of a member stretching, bending, or buckling can often be determined by the conditions of the surface paint. Highly stressed parts will show striae ripples or waves in the paint or check marks.
Grease or oil on the surface or a collection of dust along a line may indicate a crack in the metal. Pay particular attention to those areas around openings where corners or angles are cut out, at the ends of gussets or at brace connections and at transitional points where heavy and thin parts join.
Stresses in a monolithic structure may travel some distance from the damaged area and manifest itself at a remote point in some seemingly unrelated place,
The maintenance people should check all bolts, nuts, cap screws and rod bolts. Lock washers and other locking devices must be in place.
Be sure that bolted and assembled parts are tight. Evidence of movement may be detected by signs of scuffed paint, worn or bright spots adjacent to the part. Often a slight movement of parts that can't be seen with the eye can be felt with the finger tip when the machine is working.
All roner and ball bearings on the machine should be kept about 1/3 to 1/2 full of the lubricant recommended in the Lubrication Instructions. Add only enough lubricant to maintain this level. These are oil-tight bearings and the lubricant level will usually remain constant over a long period of time. Therefore, only very small quantities need be added. Unless otherwise specified, we recom ill end a sma 11 amau n t a fl u b ric ant eve ry 500 hours which will usually maintain the desired level in the bearings of about 1/3 to 1/2 full at all times.
If these bearings should ever become completely filled, the addition of more lubricant would result in pressure being built up inside the bearings and heating would result. If a bearing should run excessively warm, it is advisable to remove the pressure fittings and allow some of the excess lubricant to escape.
It is important to make sure every rotating or movable part is properly lubricated. All gears and pinions which are not enclosed should also be kept coated with a good grade of gear lubricant as recommended in Lubrication Instructions.
Oil should be kept at the proper level in all enclosed gear cases.
The lubrication specifications in this manual cover the lubrication requirements of the machine when operating within an ambient temperature range from -20 degrees to 110 degrees F.
If this machine is to be operated at temperatures below -20 degrees F. or above 110 degrees F., contact the Marion Power Shovel Company, Inc., Marion, Ohio or local supplier for special lubrication recommendations. Give full particulars concerning your conditions of operation.

Unusually dusty and dirty atmosphere, high humidity and/or extreme temperature can alter the effective life of a lubricant. Therefore, it shall be the responsibility of the operator and/or owner to determine the most effective lubrication interval in accordance with existing environmental conditions for all components, bearings (plain and anti-friction), gears, .gear cases, etc.
The crawlers and the propel shaft bronze bushings are lubricated by an automatic lubrication system.
When the mode selector lever is moved to "Propel", the automatic lubrication system is cycled to deliver to each bronze bushing a predetermined amount of lubricant and thereafter, at 7-1/2 minute intervals during the propel operation.
The system is actuated by compressed air. The air is controlled by a solenoid valve energized from the timer panel and an air pressure regulator valve with a filler and a fog lubricator. The regulator valve should be set at 70 psi.
The amount of lubricant that is delivered to each bushing is designed into the system and can not be changed. The timer has been set at the factory to cycle at an interval to provide proper lubrication and at the same time purge the bearing of dirt and grit.
Three (3) signal lights on the panel with duplicate signal lights at the operator's station indicate the following:
10 Green light - Power on.
2. Amber 1 ight Lub cycle in progress.
3. Red light - Fault in system.
Fault in system indicates any reason why the lub cycle has not been completed:
1. Plugged line or injector.
2. Lubricant supply exhausted.
3. Break in line.
4. Pneumatic or electrical fault.
When the red indicator light is on, shut down the automatic lubrication system and determine the fault.
First, check the lubricant supply and, if exhausted, replenish. (In cold weather, the grease may channel out and starve the \ pump).
If a blocked line is suspected, insert a hydraulic fitting in the test plug, (see illustration) and with a hand gun, test each line. Start the test at the master block and progress to the secondary block until the malfunction is isolated.
THIS KEY TO LUBRICATION CODE IS APPLIED TO CHARTS COVERING THE ENTIRE MACHINE-FAMILIARIZE YOURSELF WITH THE FOLLOWING TABLES:
