USE

1. On/Off Button "C" (diagram 1)

2. Switch on the tool and select speed by pushing the dial to the desired speed range.
   Speed from 5,000 - 25,000 R.P.M.'s

3. Mounting Accessories (diagram 3)

To Loosen, push Shaft Lock button "D" and hold it, while turning the Collet Nut "A" (or chuck) by hand until the shaft locks preventing further rotation. If necessary use the Wrench, "E" to loosen the Collet Nut "A"

• Change accessories by inserting an accessory into the Collet "B" (or chuck) as far possible to minimize run out and unbalance

• With Shaft Lock button "D" engaged, tighten the Collet Nut "A"(or chuck) by hand until the accessory shank is gripped by the Collet "B". If necessary use the Wrench "E" to tighten the Collet Nut "A".

• Avoid excessive tightening of the Collet Nut "A".

• Holding and guiding the tool (see diagram ⑤)

• pencil grip for precision work (engraving)

• sparing knife hand grip for rough work (grinding)

• 2 hand golf grip ideal for when you need to keep the tool parallel to the work surface, i.e. using a cut-off wheel

• Charging the tool

• The cordless rotary tool is not fully charged. The tool is equipped with a removable battery pack. Be sure to charge the battery pack prior to initial use. For best results on first charge, charge battery pack overnight.

• To charge the battery pack "H" (see diagram 1)

• Put the switch "C" in the "OFF" position.

• Squeeze release tabs "I" on both sides of battery pack"H", and remove battery pack "H" from back of tool as shown on page 2.
• Align marks "F2" on battery pack with marks "F3" on charger and insert battery pack "H" into charger "G".
• Plug charger "G" into the power source. The green L.E.D. light indicates connection has been made and the battery pack "H" is charging. Under normal usage the battery pack "H" requires 3 hours charging time to reach full capacity.
• When charging is complete remove battery pack "H" from charger "G".

• Align marks "F2" on battery pack with marks "F1" on the housing of tool. Squeeze release tabs "I", insert battery pack "H" into back of tool, and release pressure on tabs "I" so it locks in place.

• Important charging notes

• The battery pack accepts only about 80% of its maximum capacity with its first few charge cycles. However, after the first few charge cycles, the battery will charge to full capacity.

• The charger was designed to fast charge the battery only when the battery temperature is between 0^ and 40^ .
• 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.
• If you anticipate long periods (i.e. a month or more) of non-use of your tool, it's best to run your tool down until it is fully discharged before storing your battery pack. After a long period of storage, the capacity at first recharge will be lower. Normal capacity will be restored in 2 or 3 charge / discharge cycles. Remember to unplug charger during storage period.

• If battery pack does not charge properly:

• Check for voltage at outlet by plugging in some other electrical device.

• Check to see if outlet is connected to a light switch which turns power "off" when lights are turned off.
• Check battery pack terminals for dirt. Clean with cotton swab and alcohol if necessary.

GB

• If you still do not get a proper charging, take or send tool, battery pack, and charger to a Dremel Service Station for repair (address are listed on the service diagram supplied with the tool).

Note: Use of chargers or battery packs not sold by Dremel may void warranty

APPLICATION ADVICE

• Always practice on a piece of scrap material first to choose the right accessory and determine the optimum working speed
• Do not apply to much pressure on the tool; let the speed do the work for you
• Use only accessories that are recommended by the manufacturer for your model.

SPEED

Your Cordless Rotary Tool is equipped with a variable speed control dial. To turn the tool ON, rotate dial to desired number to select the operating speed needed from 5.000 - 25.000 RPM. To turn tool OFF, rotate dial to the "0" OFF position. You can refer to the charts on page 4, 5, and 6 to determine the proper speed, based on the material being worked and the type of cutter or other accessory being used. These charts enable you to select both the correct accessory and the optimum speed at a glance.

The Settings for Approximate Revolutions Per Minute Cordless Rotary Tool Variable Speed Model 780

Switch Setting	Speed Range
0	Off Position
2	1,000 - 5,000 RPM
4	6,000 - 10,000 RPM
6	11,000 - 15,000 RPM
8	16,000 - 20,000 RPM
10	21,000 - 25,000 RPM

The speed of the rotary tool is controlled by setting this indicator on the housing.

Some rules of thumb in regard to speed:

1. Plastic and materials that melt at low temperatures should be cut at low speeds.
2. Polishing, buffing, and cleaning with a wire brush must be done at speeds below 15,000 RPM to prevent damage to the brush.
3. Wood should be cut at high speed.
4. Iron or steel should be cut at top speed if using tungsten carbide accessory, but at lower speeds if using high speed steel cutters. If a high speed steel cutter starts to chatter this normally means it is running to slow.
5. Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various speeds, depending on the type of cutting being done. Use paraffin or other suitable lubricant on the cutter to prevent the cut material from adhering to the cutter teeth.

To aid you in determining the optimum operational speed for different materials and different accessories, we have constructed a series of tables that appear on diagram 6. By referring to these tables, you can discover the recommended speeds for each type of accessory. Look these tables over and become familiar with them.

Ultimately, the best way to determine the correct speed for work on any material is to practice for a few minutes on a piece of scrap, even after referring to the chart. You can quickly learn that a slower or faster speed is more effective just by observing what happens as you make a pass or two at different speeds. When working with plastic, for example, start at a slow rate of speed and increase the speed until you observe that the plastic is melting at the point of contact. Then reduce the speed slightly to get the optimum working speed.

Increasing the pressure on the tool is not the answer when it is not cutting as you think it should. Perhaps you should be using a different cutter, and perhaps an adjustment in speed would solve the problem. But leaning on the tool seldom helps.

MAINTENANCE AND REPAIR

• Keep tool, battery pack and charger clean (some household cleaning products and solvents can damage plastic parts; these products include among others benzine, trichloroethelene, chloride, ammonium
• Excessive sparking mostly indicates worn-out carbon brushes, therefor your tool should be brought to a service station.
• In case of an electrical or mechanical defect, hand in tool at one the DREMEL Service Stations for repair (addresses are listed on the service diagram supplied with the tool)
