Safety Instructions:

Before Operation
• 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 use 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
• Worn or damaged parts
• Do Not refuel machine while engine is running.
Operation
• Do examine the surface of the drill face 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 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 grades in excess of 35% (20o), or on 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.
