Before Operation:
• Do notify the owner of overhead or underground power lines before drilling. Be sure to comply
with all local regulations regarding safe operating distances from power lines. See table 1-1 for
general guidelines for safe distances from high voltage lines.
• Do study this manual and fully understand the controls.
• Do be sure all safety guards are securely in place.
• Do wear safety helmet, glasses and hearing protection when operating or working on machine.
• Do be sure all personnel are clear of the machine and work area before starting the engine or
operating machine.
• Do be sure drill area is clear of all obstructions before operating machine.
• Do attach safety chain when using towbar.
• Do Not operate machine with:
• Hydraulic or air leaks
• Broken or damaged electrical wiring or components
• Damaged hydraulic hoses or fittings

Operation:
• Do examine the surface before drilling to determine the possible presence of unfired
explosives.
• Do provide sufficient ventilation when running the engine in an enclosed area. Exhaust gasses
contain carbon monoxide, a deadly poison, which is colorless and odorless.
• Do keep work areas clean and clear of cuttings, hand tools and other objects.
• Do place feed in horizontal position with feed resting on feed rest (if equipped) when
tramming over rough ground or during long moves. When moving from hole to hole, be sure feed is
high enough to clear ground obstacles. If feed hits something while tramming, feed can fall causing
serious injury or death.
• Do Not use the machine for any other purpose than what it was designed for. This machine is
designed for blasthole drilling operations only.
• Do Not wear jewelry or loose fitting clothing when working on machinery. Keep clothing and
hands clear of moving parts.
• Do Not travel on steep inclines, soft or unstable ground or close to unsupported excavations.
• Do Not move boom or machine if it is in a potentially unstable position.
• Do Not stand directly under a boom or feed.
• Do Not drill into or near a “bootleg” hole or any hole that may contain explosives.
