6. OPERATION
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.
Start drilling
Start the tool by squeezing the variable speed trigger switch.
Release the trigger to stop the tool.
If you press the lock on button while the trigger switch is depressed, the switch is kept in the operating position. This is convenient when continuous
operating for extended periods of time is required.
To release the lock on button, press and release the trigger switch .
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 changed during drilling, this could cause
the bit to snap off blocking the hole and perhaps causing injury.
Reduce pressure as the drill is about to break through the item being drilled.
Don't force the drill, let it work at its own pace.
Keep the drill bit sharp.
Drilling wood
For maximum performance when drilling larger holes, use auger bits or spade bits for wood drilling.
Set the tool to the drill mode.
