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 joystick 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 the 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 the 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 down

Retract boom while curling pick up and raising boom (simultaneously)

Retract boom by pulling right joy back

Curl pick up by pushing left joy stick to the left
