2) limit operating time and shorten trigger time
OPERATION
WARNING : The device should be disconnected from the mains before putting into operation
BIT INSTALLATION
When selecting a drill bit, use the right type for your job. For best performance, always use a sharp drill
bit.
1. To open the chuck jaws, holdits collar while turning the sleeve in the counter clockwise direction.
Insert the drill bit deeply into the chuck, and then center the bit in the chuck jaws.
2. To close the chuck jaws, hold the collar while turning the sleeve in the clockwise direction.Tighten
securely.
3. Remove the drill bit in reverse order.
NOTE: The chucks of reversible drills are always fixed by a screw with a left hand thread. The screw must be
loosed before the chuck can be removed if necessary. To loosen the screw, turn it in a clockwise direction.
FORWARD / REVERSE ADJUSTMENT
1. For forward (clockwise) rotation, push the forward /reverse switch to the left position.
2. For reverse (counterclockwise) rotation, push the forward/reverse switch to the right position.
Although an interlock prevents reversing the tool while the motor is running, allow it to come to a
full stop before reversing.
WARNING: If the forward / reverse switch is in the central position, the tool can not be switched on.
VARIABLE SPEED TRIGGER SWITCH
WARNING: Always check that the power supply is the same as that indicated on the nameplate of
the tool.
This tool has a variable speed switch which can reach higher speed with increased trigger pressure. Speed
is controlled by the pressure to the switch trigger. The variable speed feature is particularly useful when
starting drilling. It also enables you to select the best speed for a particular application.
To limit the maximum speed of the tool, rotate the dial on the front of the trigger until the desired setting
is achieved. Turn the dial to the"+" direction to increase the speed and to the "-" direction to decrease the
speed.
NOTE: It is recommended to use the variable speed feature for a short time only. Do not continuously
operate the tool at different speeds. It may damage the switch.
LED WORKLIGHT
The tool has a LED light to illuminate the work area and improve vision when working in areas with
insufficient lights.
The LED light will switch on automatically while the trigger switch is depressed
START DRILLING
Start the tool by squeezing the variable speed trigger switch. Release the trigger to stop the tool.
HOLE DRILLING
When attempting to drill a large diameter hole, it is sometimes best to start with a smaller drill bit then
work up to the required size. This prevents overloading the drill.
WARNING: Many accidents occur because of unforeseeable situations. Please pay attention that
drilling-out a small hole may cause the drill bit to jam in the hole, especially when drilling metal.
- Remember to use a "wood-pecker" action on deep holes to allow the swarf to be ejected from the hole.
- If the drill bit snags, switch off immediately to prevent permanent damage to the drill.
- Try running the drill in reverse to remove the bit.
- Keep the drill in line with the hole. Ideally, the drill bit should enter at right angles to the work. If the
angle is
