IISAFETY PRECAUTIONSII

1. The machine should not be operated until the operator has read and understood the operating instructions for the machine and is thoroughly familiar with the location, operation and functions of all controls.

2. An operator should not operate the machine without all covers and/or guards properly mounted and secured.

3. The operator should familiarize himself with the fire suppression system of the machine.

4. Always be sure all personnel are clear of machine before starting machine.

5. Carefully test all functions before operating the machine.

6. Always wear safety glasses not only for your own safety but for that of your fellow workers. Should an operator be temporarily blinded by dust, etc., while operating the machine, the machine becomes a hazard to both men and other equipment.

7. When operating the machine, always keep all parts of your body within the confines of the operator's pit. Hanging head, arms or legs outside the pit could result in severe injury or death.

8. Take extra caution to keep from cutting the trailing cable against the rib or under the track.

9. Any damaged, broken or malfunctioning parts should be reported at once to the section foreman.

10. A permissible electrical enclosure should. never be opened by anyone except properly trained maintenance personnel.

11. The operator should never try to troubleshoot the cause of a circuit breaker trip, whether the breaker is on the machine or at the power center. Notify proper maintenance personnel to determine the cause and correct.

12. Never work under a raised cutter boom, conveyor boom or gathering head unless they are properly supported.

RECOMMENDED STEPS TO FOLLOW WHEN OPERATING THE 3612 MINER (Individual mines may require different cycles of operation.)

OPERATING PROCEDURE

Make sure that everyone is clear of the machine and all valves, breakers and switches are in the or off position.

Make sure proper voltage is being supplied to the machine.

Make sure water is being supplied to the machine.

Turn on main circuit breaker.

Turn on control circuit breakers.

Turn on area lights.

Select and turn on control valve for directional water spray.

Turn on headlights.

Start pump motor.

Raise or lower conveyor and cutter boom for adequate clearance 'and visibility.

Put gathering head in float position. For maximum cleanup efficiency, the gathering head should rest against the mine floor and be free to float.

12. Tram machine to the face until cutterhead just touches face.

13. Position the rear conveyor over the shuttle car by raising and swinging to desired position.

14. Raise the cutter boom to the desired cutting height.

15. Start the gathering head/conveyor motor.

16. Activate water spray system.

17. Start cutterhead motors.

18. Lower stabilizer shoe to help stabilize machine during sumping and shearing operation, if required.

19. Sump the cutter head into the face by pushing tram levers forward. Tram machine forward until it has advanced approximately 30" into the top of face.

20. Lower cutting head down, thus shearing the face. Do not tram during the shearing cycle.

21. When head has reached bottom, release shear switch, raise stabilizer shoe and tram machine backward 3''', thus trimming ridges and smoothing bottom. Make certain shuttlecar is clear before backing miner.

22. Raise the cutterheadand repeat cycle (19 thru 22) until desired amount of face has been cut. .

23. Turning crosscuts is accomplished by making a series of partial cuts until the machine can be turned to the desired angle.

GEARING SETUP

The 3612 Miner contains four completely separate main drive systems. They are tram, pump, gathering head/conveyor and cutter drum.

The Tram System consists of two separate drives, one for the left track and the other for the right track. The tram system works on the principle of a motor driving a shaft which drives a right angle drive and a primary planetary, which then drives a tram gear case containing three helical gears. Power is transferred through these gears to the sprocket shaft, which drives the track. Oirection of travel is determined by the direction the motor shaft is made to rotate.

The Pump System consists of a motor driving a shaft which drives a coupling assembly. Power is transferred through a coupling assembly to the hydraulic pump. The pump motor should rotate counter clockwise when viewed from the output shaft side, thus providing correct hydraulic pump rotation.

The Gathering Head and Conveyor System consists of one motor, on the left side of the machine. The power is transferred from the motor to the primary gear case, which is located on the right side of the gathering head, by means of a prop shaft. The primary gear case contains two helical gears and three spur gears and a clutch. The primary supplies power to the right side gathering head gear case. The gathering head gear case contains a coupling which drives a pinion. The pinion drives a ring gear which is connected to a table that rotates, causing the gathering arms to work. At the same time, the foot shaft sprocket turns, causing the conveyor chain and left hand gathering head gear case to work. This is accomplished by a coupling which connects the foot shaft to the gear case pinion.

The direction the conveyor chain and gathering arms move is determined by the direction the motor shaft is made to rotate. The clutch in the primary gear case allows slippage in the system, in case of blockage on the gathering arms or conveyor chain. The clutch is factory pre-set to the correct torque setting but should be checked periodically to make sure proper adjustment is maintained.

The Cutter Drum System consists of two motors, one on each side of the machine. Each motor has a dry type clutch at the back side which is driven by a motor shaft. The clutch has a wear indicator that should be checked periodically to see if disc are worn to point where replacement is necessary. The clutch disc is connected to a shaft that runs through the motor driving helical gears which drive the pinion. The pinion drives a bevel ring gear which in turn drives a double planetary that rotates the end drum. The outer planetary carrier also drives the drum drive shaft which goes back through both planetaries and the ring gearo The shaft then rotates the center drum.
