Safety:
Before Operation:
• Be sure that prior to starting the machine, all controls are in neutral or off positions and
that controls are in the position that will generate the least load upon the engine on start-up.
Especially ensure the auto pulldown is off and rotation lever is in neutral.
• Be sure that the drill area is clear of all obstructions before operating the machine.
• Ensure that the safety chain is attached when using a towbar.
• Do not operate the machine with: a hydraulic leak, broken or damaged electrical wiring or
damaged hydraulic hoses or fittings.
• Do not operate the machine without familiarising yourself with the location of all hand held
fire extinguishers.
• Be sure the fire suppression system has not been activated, is still pressurised, and that
lines and nozzles are in the correct place and not damaged.
• Do not operate the machine without familiarising yourself with the location of on-board fire
suppression activation points.
• Do not operate the machine without first checking that all emergency stops are operational and
familiarising yourself as to their location.
During Operation:
• Do not use the machine for anything other than its designed purpose for blasthole drilling.
• Do not wear jewellery or loose fitting clothing when working on the machine. Keep clothing and
hands clear of moving parts.
• Do not move the machine if the drill is in a potentially unstable position.
• Always be aware of the drill rigs automated functions and make sure people are clear of
all components. The rotary drill has an automated function of the dust curtain raise/lower
cylinders when the machine is switched from ‘drill’ to ‘propel’ mode.
• Do not propel the machine with the mast raised over undulating ground or across grades or
over any distance other than short distances on a drill pattern.
