Before starting the machine, it is essential to analyze and assess all the geomorphologic conditions of the ground (load-bearing capacity, slipping hazard, gradient, any obstructions, etc.). Check for the presence of any overhead power lines, and underground piping (gas headers, etc..) and underground utility channels (See HS-308 for safety procedures). Prior to drilling ensure you are not on ground that is steeper than 5 degrees. Build benches or have haul roads built before work activities begin. In addition, the maximum forward angle of the mast for the AF100 is 8 degrees, the maximum lateral angle of the mast is 5 degrees, and the maximum backward angle of the mast is 15 degrees. While traveling to the drilling location mast should be tilted back 60 degrees. No travel on slopes that are greater than 2 to 1, if travel is required haul roads will have to be built and health and safety manager and project manager will have to be contacted. A full bucket is better is not the case unless drilling in landfill water. A full bucket will take the driller longer to empty; twice as much material can be removed by not packing the bucket and does not damage the rig as much. When the driller is set up to begin drilling the mast should be leaning to the left 2 bars or 10 degrees on the leveler graph to compensate for the rotary torque to the left in the beginning. The mast can be straightened once the top of the bucket LX�V] is even with the ground.

To do this level the mast with a four foot level then the new pattern way check the in cab indicator. If the indicator is not level, then an adjustment will have to be made in the indicator box. The box is located where the parallel beam meets the mast. It is a small box mounted onto a large L bracket with three screws connecting the box to the L bracket. These three screws are loosened and then you adjust the screws accordingly while someone is in the cab watching the indicator. When the indicator reads level
