1. Loading and unloading of rechargeable batteries for power tools
Rechargeable battery removal: Hold the handle firmly, and then push the battery door latch to remove the battery. Rechargeable battery installation: confirm the positive and negative poles before inserting the battery.
2. Charging
Insert the rechargeable battery into the charger correctly, and it can be fully charged in about 1 hour at 20°C. Note that the rechargeable battery has a temperature control switch inside, and the battery will be cut off and cannot be charged if it exceeds 45°C. It can be charged after cooling.
3. Before homework
a. Drill bit loading and unloading. Install the drill bit: After inserting the bit, drill bit, etc. into the chuck of the switchless drill, hold the ring tightly and tighten the sleeve sleeve backwards (clockwise from below). During operation, if the sleeve becomes loose, please tighten the sleeve again. When tightening the sleeve, the tightening force will become stronger.
Disassemble the drill: hold the ring firmly and loosen the sleeve to the left (viewed from the front, it is counterclockwise).
b. Check the direction of rotation. When the selector handle is placed at the R position, the drill bit rotates clockwise (as seen from the back of the charging drill), when the selector handle is placed at L, the drill bit rotates counterclockwise (as seen from the back of the charging drill), "R" , "L" symbol is marked on the body of this machine.
Note: When using the rotary knob to change the speed, please make sure that the power switch is turned off. Changing the speed while the motor is rotating will damage the gears.
