SETUP AND OPERATION CONTINUED 4. STARTING WORK: Ensure the work area is as hazard free as possible. Select and install the tool to be used,(see paragraph 2). If required set the depth stop and adjust the support handle attachment for the most comfortable position, (see fig.3). To install the depth stop loosen the support handle by turning it anticlockwise. Insert the depth stop rod through the hole in the support handle and set to the required depth, adjust the position of the handle attachment if required and secure in place by re-tightening the support handle. For safety, always use the hammer drill Fig.3 with the handle attached. Set the required mode, (see paragraph 5). When drilling vertically overhead, fit the rubber dust collector onto the drill (see fig.4). Position the tool against the surface to be drilled, depress the OFF lock knob (10) and then squeeze the trigger switch (3). NOTE: if using the hammer action DO NOT start the drill until the tool is in contact with the surface to be drilled/chiselled etc. Fig.4 5. DRILL MODE SELECTION HAMMER STOP: Your drill is equipped with a hammer stop facility for smoother drilling. To select this mode turn the hammer control switch (7) to the position marked:. Depress the lock pin (9) then turn the drill control (8) so that the position marked: coincides with the arrow on the machines case. - 8 -
SETUP AND OPERATION CONTINUED DRILL STOP: For chiselling it is necessary to deactivate the drilling action as follows: Turn the hammer control switch (7) to the position marked:. Depress the lock pin (9) then turn the drill control (8) so that the position marked: coincides with the arrow on the machines case. HAMMER AND DRILL: To activate the hammer and drill mode turn the hammer control switch (7) to the position marked:. Depress the lock pin (9) and turn the drill control (8) so that the position marked: coincides with the arrow on the machines case. IMPORTANT! When hammer drilling you only need to apply light pressure. Too much pressure will place unnecessary load on the motor. Check the drill bits regularly, re-sharpen or replace. MAINTENANCE ALWAYS ensure the tool is isolated from the electrical supply, by switching OFF and removing the plug from the 13 amp socket before commencing any maintenance activities or adjustments etc. Clean the tool regularly, use a soft brush and or soft cleaning cloth. DO NOT use any chemicals or harsh abrasives to clean the tool. At the end of work, to prevent dust deposits you should use a compressed air (max.3 bar) to clean out the ventilation holes. Remove and inspect the carbon brushes regularly, it is very important to refit the motor brushes exactly as they are removed, DO NOT turn them around or swap their positions (dirty or worn carbon brushes result in excessive sparking and speed faults). Always replace the motor brushes in pairs. Check gearbox regularly and top up if necessary with a good quality high melting point gearbox grease. DO NOT overfill the gearbox, apply sufficient grease to cover all visible moving parts. (fig.2 refers to grease cover). WARNING: The use of spare parts or accessories, other than those supplied by CLARKE international or one of its recognised dealers, may be hazardous and could invalidate the guarantee. - 9 -

HAND-ARM VIBRATION Employers are advised to refer to the HSE publication Guide for Employers. All hand held power tools vibrate to some extent, and this vibration is transmitted to the operator via the handle, or hand used to steady the tool. Vibration from about 2 to 1500 herz is potentially damaging and is most hazardous in the range from about 5 to 20 herz. Operators who are regularly exposed to vibration may suffer from Hand Arm Vibration Syndrome (HAVS), which includes dead hand, dead finger, and white finger. These are painful conditions and are widespread in industries where vibrating tools are used. The health risk depends upon the vibration level and the length of time of exposure to it in effect, a daily vibration dose. Tools are tested using specialised equipment, to approximate the vibration level generated under normal, acceptable operating conditions for the tool in question. For example, a grinder used at 45 on mild steel plate, or a sander on softwood in a horizontal plane etc. These tests produce a value a, expressed in metres per second per second, which represents the average vibration level of all tests taken, in three axes where necessary, and a second figure K, which represents the uncertainty factor, i.e. a value in excess of a, to which the tool could vibrate under normal conditions. These values appear in the declaration on page 7. You will note that a third value is given in the specification - the highest measured reading in a single plane. This is the maximum level of vibration measured during testing in one of the axes, and this should also be taken into account when making a risk assessment. a values in excess of 2.5 m/s 2 are considered hazardous when used for prolonged periods. A tool with a vibration value of 2.8 m/s 2 may be used for up to 8 hours (cumulative) per day, whereas a tool with a value of 11.2 m/s 2 may be used for ½ hour per day only. The graph below shows the vibration value against the maximum time the respective tool may be used, per day. The uncertainty factor should also be taken into account when assessing a risk. The two figures a and K may be added together and the resulant value used to assess the risk. It should be noted that if a tool is used under abnormal, or unusual conditions, then the vibration level could possibly increase significantly. Users must always take this into account and make their own risk assessment, using the graph as a reference. Some tools with a high vibration value, such as impact wrenches, are generally used for a few seconds at a time, therefore the cumulative time may only be in the order of a few minutes per day. Nevertheless, the cumulative effect, particularly when added to that of other hand held power tools that may be used, must always be taken into account when the total daily dose rate is determined. - 12 -
