tAl5. 4) Handle the supply cord carelully.Never carry the charger by the supply cord. Don't unplugthe charger by pulling on the supply cord. Don't exposethe supply cord to heat, oil or sharp edges. lf the sup-ply cord becomes damaged while working, don't touchit - unplug the mains plug immediately..N6. lzf Keeplhe chargerand batteriesin good con-dition.Follow the instructions on care and maintenance. Nev-er 0perate the charger when it is dirty or wet. Underunfavourable conditions, dampness or dirt adherlng tothe surface of the charger may present a risk of electricsh ock.Repairs t0 the charger including, in pafiicular, replace-ment of the supply cord, may be canied out only by themanufacturer or authorised service centre using origi-nal Hilti spare parts. Failure to observe this point mayresult in damage 0r present a risk of accident. Accord-ingly, if necessary, have the charger repaired at a Hiltiservice centre or authorised Hilti repair workshop.

A surrty precautionsWhen using electric appliances, the following f unda-mental safety precautions must always be observed inorder to avoid the risk of injury, electric shock and firehazards. Please read and observe the instructions belowbefore using the appliance.

t^ l1. lZ\ 4uo;X short circuits.Short circuiting the contacts of the charger or batteryoresents a risk of fire.2. Take the inlluences ol lhe surrounding area intoaccount.Don't expose the charger to rain and don't use it in damp0r wet surroundings or in the vicinity of flammable liq-uids or gases.,\-g. lZ\ cneck the charger each time belore use.Checkthe condition ofthe charger, supply cord and plug.Don't use the charger if it is found to be damaged, incom-plete or if the controls cannot be operated c0rrectly.4. Use the chalger only lor the puryose for which it isintended.

Before usef ^ l f ^ lLl\l Z\1 lt is essential that the safety precautions print-ed in these operating instructions are read and observed.f l/\ Connect the charger to the mains supply.- The mains voltage must corresp0nd to the infor-

mation given on the rating plate.- All thtee indicators light brielly during lhe sell-tesl, atter which only lhe green LED should light.- The green LED blinks when the self-test was NOTsuccessful. lf, after unplugging and reconnectingthe charger to the mains supply, the self-test is stillnot successful, please return the charger to a Hiltiservice centre for reoair.A]/'\ Operale the charger only at a suitable location.- The location for operation of the charger shouldbe dry, clean and cool but not exposed to frost.- The charger must be able to give off heat duringthe charging procedure. Accordingly, the ventlla-tion slots must always be unobstructed.

0peralionInserling the batteryBP 6-86 for the TE 6-4:Insert the battery in the dovetail guide and push it inuntil a click is heard (engaged). ESBP '10 for the SB 10:SBP 1 2 for the SB 1 2:Push the battery into the compartment as far as jt willgOETake care to ensure that the battery fits correctly in thecharging compadment.A The charger is designed for use with the batterieslisted above. lt must not be used to charge otherbatteries.Indicators ZlGreen LED - Lights when the charger is connectedto the mains supply- Blinks when the self-test determines afault in the charger or batteryRed LED - Lights when the battery is beingcharged (charging in progress)- Blinks when the battery is charged(workinq capacitv reached)Yellow LED - Blinks when the battery is too cold (approx.0'C) or too hot (approx. 60"C). The

charger begins charging automaticallyas soon as the battery reaches the requiredremperaru re.- Lights when the charger is operating inconditioning charge mode.

Condilioning charge mode ENiCd cells are subject to self-discharge. With older bat-teries, the rate of self-discharge of some of the cells maybe higher than that of others. As conventional chargersswitch off when the first cells have reached full charge,the other partly charged cells do not receive the fullcharge. The user becomes aware of this effect in theform of inadequate battery capacity.This effect can be eliminated by applying a conditioningcharge. During this procedure, the charger supplies asmall current over several hours, with pauses made inorder to avoid overheating the battery. Depending on itscondition, the llattery will take 7 to 10 hours t0 reachfull charge.The conditioning charge begins when the conditioningmode button is pressed before insertion of the batteryand released approx. 3 seconds after the battery hasbeen inserted. The yellow LED lights while the batteryis being charged in conditioning mode.The battery should be charged in conditioning mode nomore than once a month. The conditioning charge is,so to speak, a kind of "training" for the battery. Just asexcessive training can be harmful to the human body,t00 frequent use of conditioning charging mode can alsoweaken the battery.

Baltery (accessory)f ^ l/\ Brforr a battery is used for the first time, it mustbe charged for 24 hours in normal mode or for 1 0 hoursin conditioning mode in order to permit "forming" of thebattery cells.-At iow temperatures: Battery performance drops atlow temperatures. Store batteries at r00m tempera-ture when not in use.-At high temperatures: Do n0t store batteries wherethey may be subjected t0 high temperatures (e.9.exposed to the sun, at a window, behind a car wind-screen or on a radiator).Never fully discharge a battery. Change the battery ass00n as its 0erformance droos. The cells that reach astate of total discharge first will otherwise be damagedby the current still being drawn from the other cells.An excepti0n to this is the BP 6-86 battery for theTE 6-4 (this battery is equipped with an electronic deepdischarge prevention device).
