Safety
Safety Hazards

The Rotary Blasthole Drill is a heavy moving machine with a mast which raises vertically for drilling. Like all moving objects and reach extending devices, there are potential hazards associated with its use. These hazards will be minimized if the machine is properly operated, inspected and maintained. Operator’s must read this manual and have been trained to use the machine in an appropriate and safe manner. Non-English speaking persons must have an interpreter explain all safety and operating procedures in this manual. Should any questions arise concerning the maintenance or operation of the machine contact your Cat dealer.

Before Operation
• Do study this manual and fully understand the controls.
• Do be sure all safety guards are securely in place and all access doors are closed and locked.
• 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 and know the size limitations of the
machine.
• Do attach safety chain when using towbar.
• Do Not operate machine with:
• A hydraulic leak
• Broken or damaged electrical wiring
• Damaged hydraulic hoses or f ttings

Operation
• Do provide suff cient ventilation when running the engine in an enclosed area. Exhaust gasses
contain carbon monoxide, a deadly poison, which is colorless and odorless.
• Do make sure the drill pipe is secured in the loader before raising or lowering the mast, if your
machine is equipped with a drill pipe loader.
• Do make sure the mast lock pins are engaged in the mast base before starting drilling operations.
• Do examine the surface before drilling to determine the possible presence of unf red explosives.
• Do use PPE (personal protection equipment) appropriate for the conditions you are working in; e.g.
safety helmet, safety glasses, hearing protection, gloves, respirator.
• Do Not wear jewelry or loose f tting clothing when working on machinery. Keep clothing, hands
and hair clear of moving parts.
• Do Not drill into or near a “bootleg” hole or any hole that may contain explosives.
• Do Not use the machine for any other purpose than what it was designed for. This machine is designed
for rotary blasthole drilling operations only.
• Do Not travel on steep inclines soft or unstable ground or close to unsupported excavations.
• Do Not move machine if drill is in a potentially unstable position.

Maintenance
• Do be sure two people are present when performing service work, both being fully trained on the
safety issues. One person shall supervise from the operator’s position and have immediate access
to an emergency stop in all situations. Visual, audible or verbal communication signals must be
established and understood by both persons.
• Do be sure each person is adequately trained to perform service and maintenance procedures.
• Do place a warning tag on starting controls to alert personnel that someone is working on the machine
and disconnect battery before making repairs or adjustments to machine.
• Do be sure you have adequate lighting when performing service work at night.
• Do relieve pressure on hydraulic or pneumatic systems before loosening connections or parts.
• Do be sure machine and components are well supported before servicing or replacing parts.
• Do maintain a metal-to-metal contact between the f ll nozzle and fuel tank when f lling the fuel tank.
This will prevent sparks and the possibility of an explosion.
• Do Not hammer bit or drill pipe. Use only proper tools to make repair or adjustments.
• Do Not weld or grind near oil lines.
• Do Not attempt to remove radiator cap when engine is hot or has overheated.
• Do Not smoke or use an open f ame near batteries, when servicing the batteries. Batteries can
give off hydrogen which is a highly explosive gas.
• Do Not leave tools or other loose objects on the engine, drive mechanisms or drilling platform.
They could be thrown by this equipment with a powerful force.
