Ensure pin is secure and in place. Underground mine fires cause carbon monoxide gas and oxygen deficient atmosphere and can be explosive with right mixture of oxygen. At least one fire fighting system must be operable at all times.  If defects are found on both systems, tag-out drill and immediately report it to supervisor. Check fire suppression cartridge and ring pin. Check gauge to ensure properly charge Ensure pin is secure and in place. Ensure LED indicator is functioning and green light is on Underground mine fires cause carbon monoxide gas and oxygen deficient atmosphere and which can be explosive with right mixture of oxygen. Inspect ROPS structure Check for cracks Check for broken weld Check for loose or missing bolts Start engine Enter cab Maintain 3 points contact during mounting and dismounting Turn key clock wise Never leave equipment idling unnecessarily due to DPM regulations Ensure back up alarm is functional All operators shall look behind prior to backing up Ensure horn is functional Horn button (red) is located on both joy sticks Check hydraulic safety switch Safety switch is located on right arm rest of operator seat Raise arm rest to disengage  hydraulic functions Check lights Flip toggle switch to on position Assure all lights are on Check windshield Check for cracks Ensure windshield is properly within the seal Clean windshield as needed Check for wiper operation. Check engine speed control Dial knob to desired RPM Check tram alarm Release parking brakes Tram forward and reverse to assure alarm is functioning Listen for alarm Check yellow strobe light Strobe must be operational before scaling operation begins.  This is a secondary precaution to the posted warning sign. Check park brakes Engage park brake by lifting mushroom knob up and attempt to tram forward and reverse If park brakes do not hold, tag out and notify supervisor. Check digging brakes While in low tram, the digging brake will apply automatically when tram pedal is released. While in high tram, the digging brake will not apply when tram pedal is released.  Manual brakes must be used when using high tram. Report any safety defects and/or unusual conditions to the supervisor and immediately shut down and tag out equipment Fill out pre-shift inspection form immediately after conducting pre-shift inspection Responsibility of the operator to complete form.  If form is not completed, the employee will be disciplined. Pink copy is kept with machine Tramming and Back Scaling operation Complete Pre Shift Inspection (duty 3) prior to tramming Throttle engine to desired RPM Three quarter throttle desired Release park brake after air pressure reaches approximately 90 PSI Lower right arm rest to engage hydraulic system Right arm rest serves as safety switch. Raise boom 2 feet from ceiling pulling back on left joy stick Lights aid in inspecting ceiling when tramming Push or pull on steering wheel to adjust to a comfortable operating position Depress foot pedal to forward position to release digger brakes Begin tramming Press foot pedal and steer scaler with steering wheel Tram to desired location Inspect for scales on back and ribs while tramming While tramming be aware of trailing cables, mobile equipment, power centers, and pedestrian traffic If scales are observed, follow scaling procedures. Post room with sign: "scale area do not enter" Inspect face area for any unusual atmospheric condition Refer to gas chart Inspect face area Lower boom to parking position Set park brakes Dismount scaler using caution maintaining 3 point contact Explain mounting and dismounting hazards. i.e. 3 points of contact and do not jump from ladder Remain approximately 60 feet from face area (2 shot back) Inspect face for misfire caps Check for expose lead lines of caps (green line) Post area with blasting sign if a misfire is found Notify supervisor and any other workers in area immediately when a misfire is found. Back scaler out of face, approximately 150 feet. Never attempt to remove a misfire cap unless trained Inspect ceiling for abnormally large scales Notify supervisor if scaler determines that the scale could cause potential equipment damage and/or endanger operator. Inspect for uneven floor Uneven floor will affect the stability of scaler Use caution when this condition exist Tram to center of room approximately 60 feet from face in preparation for scaling Scale ceiling (A) Begin scaling on the left side of ceiling scaling to the right side (clock wise) Stop machine at desired location Release tram pedal to set digger brakes Set park brakes Set park brakes if condition warrants: incline or decline Pull up on park brake knob to set brakes Raise boom to working height Swing boom clock wise inspecting ceiling around scaler If scale is observed, remove the scale Position boom over left front tire by continuing to swing in a clockwise motion Follow boom radius chart Push right joy stick right to swing right Swinging left with boom lowered, creates a blind spot Curl pick up by pushing the left joy stick to the left Extend boom to area to be scaled by pushing right joy stick forward Curl pick down when contact is made with ceiling by pulling left joy stick to the right. This should create an approximate half inch impression in salt Maneuver boom by rotating it if necessary to aid in knocking scales down and to see the tip of pick Push right joystick toggle switch left or right to rotate boom Instructor needs to explain functions of boom roll Extend boom while curling pick down and lowering boom (simultaneously) This will create a scraping action across the ceiling knocking down the scales Extend boom by pushing right joy stick forward Curl pick by pulling left joy stick to the right Lower boom by pushing left joy stick forward Boom should never be extended beyond  half the telescoping range (approximately 23 feet) This prevents unnecessary stress on the equipment and long term break downs Retract boom while curling pick up and raising boom (simultaneously) Retract boom by pulling right joy stick back Curl pick up by pushing left joy stick to the left Raise boom by pulling left joy stick back Swing boom right approximately 6 to 12 inches and repeat scraping process throughout swing radius (to the right tire) Refer to boom radius chart Assure boom radius area is completely scaled Reset to next setup Release park brakes if applied Tram forward to desired location (approximately 23 feet) Set park brakes if needed Repeat ceiling scaling process Repeat process until all loose scale has been removed from ceiling in position A Scale face  (A) Retract boom completely Tram forward toward face  (stopping approximately 5 feet from face) Set park brakes if needed Extend boom to the point where ceiling and face meets Extend boom to area to be scaled by pushing right joy stick forward Curl pick up Curl pick up by pushing the left joy stick to the left Scale face by curling pick in a downward motion until pick breaks contact with face Curl pick down by pulling the left joystick to the right This should create an approximate half inch impression in salt Maneuver boom by rotating it if necessary to aid in knocking scales down and to see the tip of the pick Push right joystick toggle switch left or right to rotate boom Instructor needs to explain functions of boom roll Swing boom to the right approximately 6 to 12 inches See boom radius chart Assure boom radius area is completely scaled Repeat the process from ceiling to floor within boom radius Raise the boom to desired height Release park brakes if applied Ensure there no obstacle in travel way of scaler by rotating cab to right Back away from face Depress the base (heel) of the tram pedal fully Tram approximately 80 feet from the scale portion of the face Reposition to scale ceiling and rib of right side of room (B) Steer scaler to right side of room on an angle See scaling diagram Set park brakes if needed
