The values contained here are given only as guidelines, and are not intended as
a recommendation for safe operation. Safe operation is dependent on operator
experience and judgement, ground conditions and proper preparation of ground
surfaces, and accelerations due to sudden change of direction or speed of
movement, either from operator input or ground condit ions on which machines
are operating.
Machines are typically much more stable operating wi th the mast down anytime
a machine is operating on rough ground conditions, signifi cant slopes, or there
is any doubt about the machine stability or its ability to be operated safely in the
conditions in question.

NOTE
Maximum Wind Speed = 75 MPH (120.8 Km/h) at which time dri lling must be stopped, mast

Safety Guidelines
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 oper-
ating 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 fittings
Operation
• Do provide suf ficient 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 unfired 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 fitting 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 de-
signed 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.
After Operation

Safety Guidelines
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 beestablished 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 ma-
chine 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 fill nozzle and fuel tank when filling 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 flame 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.
Equipment Transfer
• If all or part of the equipment is shipped to a new destination, always include a complete instruction
manual or a copy of the following topics from the operator's manual:
• Safety Section
• Operation Instructions including:
• Pre-Start Checks
• Start-up
• After Start Checks
• Shutdown Procedure
• Propelling Machine

Engine Monitoring System (EMS)Display
Overview
g00746960Illustration 53
The EMS display is used to display various engineparameters. The EMS display supports backlightingin order to provide excellent visibility in various lightconditions.
The engine ECM processes the operatingparameters and diagnostic information beforesending this information to the EMS display via theCAT data link. The main gauge module displaysthe information that is received from the ECM. Onlytwo wires are required from the ECM to the displayfor communication of all of the engine operatingparameters.
The EMS display incorporates three individualgauge modules which can be installed in variouslocations in order to enhance operation. One maingauge module is required for each desired operatorstation. The tachometer module and the quadgauge module are optional. These optional moduleswill NOT operate without being connected to a maingauge module.
The following information describes the functionand the requirements for installation of each gaugemodule:
The main gauge module has ten indicators (tworows offi ve) that are used to display the systemdiagnostics. A digital LCD readout displays theparameters that are monitored. When metric valuesare displayed, the units of measurement arealso displayed. When US values are displayed,
the units of measurement are not displayed. Forexample, if metric values are being displayed, thereadout would be “35 kPa”. If US values are beingdisplayed, the readout would be “5”. (The unit of measurement “psi” is NOT displayed.)
The following parameters are monitored:
• Auxiliary pressure
• Auxiliary temperature
• Battery voltage
• Coolant temperature
• Engine hours
• Engine load (percent)
• Engine oil pressure
• Engine speed
• Fuel pressure
• Fuel rate
• Fuel temperature
• Inlet air temperature
• Turbocharger outlet pressure (boost)
The quad gauge module has graduated warningzones that display information in an analog format.
The quad gauge module displays the followinginformation:
• Battery voltage
• Coolant temperature
