Before Operation:
• Do study this manual and fully understand the controls.
• Do be sure all safety guards are securely in place. Replace any damaged or missing guards.
• Do be sure all nameplates and decals pertaining to safety, operation, and maintenance are in
place and not damaged. Replace any damaged or missing nameplates or decals. Refer to decal locator
drawings in this section.
• Do be sure all personnel are clear of the machine and work area before starting the engine or
operating the machine.
• Do be sure drill area is clear of all obstructions before operating machine.
• Do attach safety chain when using towbar.
• Do wear safety helmet, glasses and hearing protection when operating or working on machine.
• Do Not operate machine with:
• Hydraulic or air leaks.
• Damaged hydraulic hoses or fittings.
• Broken or damaged electrical wiring.
• Damaged or missing guards and shields.
• Damaged structural members.
• Worn or damaged mechanical parts.
• Damaged or missing fasteners.
• Broken, damaged, or malfunctioning controls.
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 gases
contain carbon monoxide, a deadly poison, which is colorless and odorless.
• Do keep work area clean and clear of mud, snow, ice, fluids, hand tools and other objects.
• Do raise the drill feed before moving the machine. Raise it high enough to allow for rough
ground or small hills. Drill feed can fall causing serious injury or death.
• Do wear seat belt and operate machine with door closed on cab machines.
• Do maintain minimum clearance from high voltage wires (see Table 1-1). Check with power
company and local regulations for specific guidelines and safety information.
• Do Not use the machine for any other purpose than what it was designed for.
• Do Not wear loose clothing or jewelry; 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.

After Operation:
• Follow Shutdown Procedures given in Section 4 of this manual.

Maintenance:
• Two people shall be present when performing service work, both being fully trained on 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 shall be
established and understood by both persons.
• Do relieve pressure in the hydraulic or pneumatic systems before loosening connections or
parts.
• Do use only proper tools to make repairs or adjustments.
• Do be sure of adequate lighting when performing service work at night.
• 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 explosion.
• 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 machine and components are well supported before servicing or replacing parts.
• Do Not service, or perform maintenance, while machine is running, or capable of being
started.
• Do Not hammer bit or drill steel. Use only proper tools to make repair or adjustments.
• Do Not weld or grind near oil, air, fuel lines, or batteries.
• Do Not smoke or use an open flame near batteries. Batteries can give off hydrogen which is a
highly ex- plosive gas.
• Do Not direct high pressure cleaning agents or water on electrical connections.
