3 We certify that the above DTH hammer has been manufactured in compliance with Halco BS EN ISO 00:000 Quality Procedures. Important: Please refer to enclosed instructions before commisioning the hammer. Attention: Prière de lire les instructions jointes avant de mettre en marche. Importante: Sirvanse de consultar las instrucciones adjutadas antes de poner en marcha el martillo. Wichtig: Vor der Inbetriebnahme eines Hammers beachten Sie bitte die Instruktionen in dieser Broschüre. COMMISSIONING INSTRUCTIONS SAFETY EQUIPMENT Always wear the appropriate safety equipment. (Please check with local safety regulations) NEW HAMMER OR CHUCK WITH USED DRILL BIT Check the drill bit splines for wear otherwise damage to the chuck could occur. MANUAL HANDLING Components might be heavy. Please carry out a manual handling assessment prior to use. USER CERTIFICATE IDENTIFICATION NUMBERS Keep a note of equipment serial numbers for future reference. Retain the certificate and spare parts list supplied with the hammer. HAMMER MODEL: HAMMER PART NO: HAMMER EQUIPPED WITH SPLINE DRIVE PINS HAMMER SERIAL NO: Always ensure that a full set of serviceable drive pins are fitted to these hammers before operating otherwise damage to splines will occur. In these circumstances, warranty from the manufacturer will not apply 0 SUB ADAPTOR A Sub Adaptor will be required if the hammer top thread differs to the drill tube thread. GREASE COMPONENTS Grease all threads and splines when assembling drill bit into hammer. CHECK DRILL BIT DIAMETER Never try to use a drill bit which is larger in diameter than a partially drilled hole. NON RETURN VALVE You may remove the non return valve in dry drilling conditions to give a slight increase in performance. COMMISSIONING Ensure hammer lubricator is working. Pour / pint (0.0 litres) of air line oil into hammer. When attached to drill rig, blow through with air to ensure all internal parts are lubricated. Operate at low pressure initially, progressively increasing, during the first hour, in order to run in the hammer. BIT RETAINING RINGS Never mix pairs of bit retaining rings which generally are manufactured as matching pairs and always re-fit them in the same orientation as when dismantled from the hammer.

4 LUBRICATION INSTRUCTIONS Choosing the Right Drill-Bit LUBRICATING OIL Head Designs Inserts Types Just like any other piece of precision machinery, the DTH hammer must be lubricated and small quantities of oil should be injected into the air stream at regular interval whilst the hammer is working. Rock drill oils are recommended because these contain the emulsifying and viscosity additives necessary to deal with high pressure and high air flow conditions in which water is usually present, if only from condensation in the air line. Oil not only provides slip to prevent pick up and premature failure of components but it also acts as a seal on the surface of running parts to use air efficiently without pressure loss. It is therefore of paramount importance that the correct grade of oil is used at the appropriate consumption rate to suit volume and pressure, in line with the hammer manufacturers recommendation. Most modern valveless hammers, particularly when operating at high pressures need a heavy oil providing of course that ambient temperatures allow the oil to run through the airline. Flat Face Ballistic Inserts Hammer Oil Consumption Per Hour DTH Hammers Need Alternative design for all rock conditions especially fractured and fissured rocks and changing formations. Suitable for soft and medium compact low abrasive rocks producing large cuttings. Not suitable for badly fractured rocks. Air Volume CFM M³ / MIN 00.0 / of imp. pint of oil per hour per 00 CFM of air consumed. 0.0 Or L of oil per hour per M³ / Min of air consumed Up to double the amount of oil is required when used with water injection. At temperatures below C oil with an antifreeze additive may be required Concave Domed Inserts Litres / HR Pints / HR..0. Alternative design for all rock conditions particularly deep hole drilling can improve hole alignment as a result of inverted pilot. Strong rugged shape for high performance and good service life in all conditions particularly suitable for very hard abrasive rocks and deep hole drilling.

5 Operating DTH Hammers ROTATION Speeds Thrust (Pulldown) / Holdback / Torque Where drill bit life and cost is a major consideration on a drill site, rotation speeds should be carefully monitored. DTH drill bits are rotary - PERCUSSIVE tools with the emphasis on PERCUSSIVE. Their function is to fracture the material being drilled which should then be immediately carried away by the exhaust air. Button bits have no cutting or tearing action as such and the effect of rapid rotation can be detrimental to the life of the bit, especially in abrasive rock which wears away fast moving peripheral inserts or in solid dense material which causes the peripheral inserts to overheat and spall due to friction. If the string is rotated too slowly, the buttons impact previously chipped areas of the hole with a resultant drop in penetration speed. As a general guide - the harder the rock or the larger the bit diameter - the slower the rotation speed required. It may be necessary to increase the rotation speed where the rock is badly fissured in order to prevent stalling. A bit stalling in the bore hole could be the result of an overly worn bit. Increasing the rotation speed in these circumstances will only accelerate the problem. Thrust should be kept as low as possible at all times to avoid excessive vibration in the drill string. Hold back should be increased more and more as additional rods are added and as drilling progresses. DTH drilling is primarily percussive drilling using the energy imparted by the hammer piston to the rock through the bit. Any attempts to apply too much weight could damage the bit, hammer and drill string and impair the drilling rate. Although the base of the hammer should maintain contact with the drill bit, there should not be excess thrust or vibration due to the reaction between the hammer and drill bit. Insufficient thrust will cause the hammer to bounce resulting in a low blow energy to the rock causing vibration and also potential damage. Recommended Thrust Capacities Hammer Size Min. Thrust Max.
