Page 2 Safety Identification and Safeguards WARNING Read and understand all safety instructions carefully before operating this machine. Failing to follow these instructions may result in serious personal injury. Important Safeguards Keep clear of rotating equipment and never wear loose clothing to tangle in machinery Always maintain a clean and tidy work area. Pick up unnecessary items. Store tools. Avoid dangerous working environments and lack of ventilation. Do not operate equipment while under the influence of drugs, alcohol, or medication. Keep visitors at a safe distance and away from the work area where they may be injured. Wear protective equipment, hard hat, safety glasses, hearing protection, gloves and hard toed boots. Read and understand the operations manual and any and all labels affixed to the machine. Use only genuine PHQ replacement parts. Failure to do so could cause rapid and severe damage to the machine or ultimately the operator. Pirate replacement parts may void the warranty of mating parts. Employ qualified service technicians to repair rock drills. An un-trained mechanic could possibly make errors in installing parts and cause severe damage to mating parts in the machine. Ensure that the drill and accessories comply with applicable company safety and health regulations. Do not exceed the rated capacity of any piece of equipment. Do not change or alter the drill, its components or accessories without prior approval from PHQ. Unauthorized alteration voids the warranty, and could render the equipment unsafe. Before moving a control, be certain what function it operates and the ramifications of that function. Breathing protection must be worn when working with materials which produce airborne particles. Prolonged exposure to vibration causes serious arm/hand vibration syndrome disease (White Finger) For additional information on training or start up, contact your PHQ representative. WARNING Operating a Rockdrill without lubricant or with incorrect lubricant is the leading cause of failure of rock drill parts. Lack of lubrication can rapidly cause EXTENSIVE DAMAGE to the working parts of this machine. All Rockdrill repairs should be preformed by properly trained and equipped personnel. NOTE: No claim for product warranty of premature failed parts will be considered when it is evident that the failures were caused by a prolonged lack of proper lubrication. No claim for product warranty of premature failed components will be considered by PHQ if parts other than those manufactured by PHQ are deemed to have caused the failure. Version 200711
