OFFICIAL USE
for ASC & Sales Shop
Model DHS680 is a 165mm (6-1/2”) Cordless circular saw powered by
18V Li-ion battery.
Its main features are:
• High-efficiency Brushless motor to provide compact and lightweight
design and high power.
• Lightweight design achieved by using durable but light magnesium die-cast
for base, blade case and safety cover
• Automatic speed control: automatically changes the cutting speed
according to load conditions.
Note: 1.3Ah Li-ion battery of BL1815 cannot be used for this model.

Caution for Handling of Rotor
When handling or storing multiple Rotors, be sure to keep a proper distance between Rotors as shown in Fig. 13R
Because Rotor is a strong magnet, failure to follow this instruction could result in:
Finger injury caused by pinching between Rotors pulling each other
Magnetic loss of Rotors or damage on the magnet portion of Rotor. (Fig. 13F)

Note in Repairing
Whenever you find any trouble in your machine, first, refer to this list to check the machine for solution.
(1) Use the full charged battery that has a star mark. (Fig. T-1)
(2) When Housing is disassembled, check the conditions of the electrical parts
(Connectors, Lead wires, Switches, etc.), Rotor, Stator, Gear section, etc.
(3) Do the running test 10 times in every work mode.

And, check the figure in the tester.
Note: Be careful not to attach the bars in reverse.
1. Set Digital tester (1R402) in the diode mode
( mark on the tester).
4. There is no fault on FET of Controller
if the tester indicates within 0.79V - 0.81V.
If it indicates 0V or 0.4V approx.,
