SPECIAL SAFETY INSTRUCTIONS BEFORE USING THE APPLIANCE 1. Examine the drilling surface for hidden electric cables,gas pipes or other obstacles with e.g.metal detector. 2. Check the following points: • Does the voltage of the motor correspond with the mains power supply? • Are the extension cable, cord insulation and plug in good condition:sturdy,not loose or damaged? • Is there a good connection at the socket? • Is the drill running abnormally, overheating or generating excessive sparks? • Should any of the above problems be observed cease all further use and make immediate repairs. Ferm Ferm 9 OPERATION TROUBLESHOOTING Hammer drilling requires low operator pressure. An excess of pressure can cause the motor to be unnecessarily overloaded. Motor does not rotate upon switching on power supply - Power supply breakage Inspect power supply - Poor switch contact Repair or replace ON/OFF switch - Mains voltage too low - Extension cord too long/ too thin - Motor damaged Repair your machine by an expert. - Worn out brushes Replace carbon brushes MANUAL SIDE GRIP The manual side grip can be rotated to either side of the machine to ensure safe and comfortable operation for both left and right-handed operators. 1. Loosen the grip by turning anti-clockwise. 2. Rotate the grip to the desired position. 3. Tighten the grip firmly. CHANGING AND REMOVING DRILL BITS Fig.B Before changing drill bits check that the mains plug has been removed from the socket. Check drill bits regularly Blunt drill bits should be re-sharpened or replaced 1. Lightly lubricate the shaft of the drill bit before inserting into the machine. 2. Place the shaft of the drill bit into the opening of the drill chuck and twist until latched. 3. To release and remove the drill bit pull back the collar of drill chuck . ADJUSTING DEPTH STOP 1. Loosen the manual side grip. 2. Place the straight part of the depth stop through the hole in the grip. 3. Adjust the stop to the desired bit depth. 4. Tighten the grip firmly. Motor generates abnormal noise and rotates slowly or not at all - Motor overloaded due to excessive pressure or drilling depth Reduce pressure or drilling depth,decrease force - Motor damaged Repair your machine by an expert. - Main power supply voltage too low Adjust main power supply voltage - Worn out brushes Replace carbon brushes Overheating of gearbox surface Overloading or blunt drill bit Reduce load or sharpen drill bit Decreased voltage Adjust main power supply voltage Heavy sparking of the motor Check if carbon brushes are not worn out. INSTALLING DUST CATCHER Fig.C The dust catcher prevents large amounts of drilling dust entering the machine when drilling into ceilings. 1. Remove the drill bit. 2. Slide the dust catcher over the shaft of the drill bit. 3. Place the drill bit with catcher in the drill chuck. 4. Always replace a damaged dust catcher immediately. MODE SELECTOR SWITCH Fig.D The correct switch lever positions required for each drilling mode are indicated in the diagram at page 2. D1 = hammerdrilling . D2 = drilling. D3 = chiseling. SWITCHING ON AND OFF To start drill:depress ON/OFF switch. To stop drill:release ON/OFF switch. DRILL WITH DRILL CHUCK ADAPTER Fig.E When drilling steel,wood and plastic,it is advisable to use the ring gear chuck and the drill chuck adapter. 8 Ferm Ferm 5 MAINTENANCE Make sure that the machine is not live when carrying out maintenance work on the motor. REPLACING CARBON BRUSHES • To check or replace the carbon brush loosen the cap with a screwdriver. • Remove the carbon brush and replace if necessary. • Tighten the carbon brush cap. • Change both carbon brushes simultaneously. • Check regularly for wear and tear. • Always change well worn carbon brushes. • Always keep carbon brushes clean and free of hindrance.
