IMPORTANT CHARGING NOTES
1.The charger was designed to fast charge the battery only when the battery temperature is between 32˚F (0˚C) and 113˚F (45˚C). If the battery pack is too hot or too cold, the charger will not fast charge the battery. (This may happen if the battery pack is hot from heavy use). When the battery temperature returns to between 32˚F (0˚C) and 113˚F (45˚C), the charger will automatically begin charging.
2.A substantial drop in operating time per charge may mean that the battery pack is nearing the end of its life and should be replaced.
3.Remember to unplug charger during storage period.
4.If battery does not charge properly:
a.Check for voltage at outlet by plugging in some other electrical device.
b.Check to see if outlet is connected to a light switch which turns power “off” when lights are turned off.
c.Check battery pack terminals for dirt. Clean with cotton swab and alcohol if necessary.
d.If you still do not get proper charging, take or send tool, battery pack and charger to your local Bosch Service Center. See “Tools, Electric” in the Yellow Pages for names and addresses.
Note: Use of chargers or battery packs not sold by Bosch will void the warranty.
TOOL TIPS
Following a few simple tips will reduce wear on the tool and the chance of injury to the operator.
NOTE: The high efficiency available from the rotary hammers can only be obtained if sharp and undamaged accessories are used. The “cost” to maintain sharp and undamaged accessories is more than offset by the “time saved” in operating the tool with sharp accessories.
You will extend the life of your bits and do neater work if you always put the bit in contact with the workpiece BEFORE pulling the trigger. During operation, hold the drill firmly and exert moderate, steady pressure. Too much pressure at low speed will stall the hammer. Too little pressure will keep the bit from cutting and cause excess friction by sliding over the surface. This can be damaging to the drill and bit.
Shanks of all drill bits should be wiped clean prior to using and immediately after removing.
Recall these instructions for safe operation:
1.Some materials require slow drilling speeds; whereas, others require higher speed to produce the best results.
2.All work must be supported or secured before drilling and steady, even pressure applied in line with the drill bit.
3.As the drill bit cuts through the opposite side, reduce the pressure and continue running the drill as the bit is withdrawn.
Materials such as glass, porcelain, ceramics, tiles, plastics, etc., should be drilled at low speeds with specially designed drill bits and lubricants.
DRILLING WOOD OR PLASTIC
If backing block is not used, ease up on the pressure just before the bit breaks through the wood to avoid splintering. Complete the hole from the opposite side immediately after the point breaks through. If bit binds, reverse the drilling operation to help remove the bit from the work.
DRILLING METAL
Make a center punch in the material for easier starting. Use enough pressure to keep the bit cutting. If the bit is allowed to merely spin in the hole, it will become dull within a short time. When drilling a larger hole, it is faster and easier on your power pack to first make a smaller hole and enlarge it to the required size. Lubricate the tip of the bit occasionally with CUTTING OIL for easier metal drilling. If bit binds, reverse the drilling to help remove the bit from the work.
