WEN 49112 Apex Pro 12V Lithium Ion Drill/Driver - Manual (Page 9)

When using drill in the LOW speed range, the speed will decrease and the drill will have more power and torque.
When using drill in the HIGH speed range, the speed will increase and the drill will have less power and torque. Use
LOW speed for high power and torque applications and HIGH speed for fast drilling or driving applications.
Use LOW speed for starting holes without a center punch, drilling metals or plastic, drilling ceramics, or in
applications requiring a higher torque.
HIGH speed is better for drilling wood and wood composites and for using abrasive and polishing accessories.
NOTE: Avoid running the drill at LOW speed for extended periods of time. Running at LOW speed under constant
usage may cause the drill to become overheated. If this occurs, cool the drill by running it without a load at HIGH
speed.
CAUTION: Never change gears while the tool is running. Failure to obey this caution could result in serious
damage to the drill.
LED WORKLIGHT
The LED worklight, located on the front of the Drill/Driver, will illuminate when the trigger switch is depressed.
This provides additional light on the surface of the workpiece for operation in lower-light areas.
The LED worklight will turn off when the trigger switch is released.
TORQUE ADJUSTMENT RING
This tool is fitted with a torque adjustment ring to select the operating
mode and to set the torque for tightening screws. Large screws and hard
workpiece materials require a higher torque setting than small screws and
soft workpiece materials.
For drilling in wood, metal and plastics, set the collar to the drilling
position symbol.
For screwdriving, set the ring to the desired setting. If you do not yet know
the appropriate setting, proceed as follows:
1. Set the collar to the lowest torque setting.
2. Tighten the first screw.
3. If the clutch ratchets before the desired result is achieved, increase the ring setting and continue tightening the
screw.
4. Repeat until you reach the correct setting. Use this setting for the remaining screws.
DRILLING
1. Use sharp drill bits only.
2. Check the direction of rotation selector for the correct setting (forward or reverse).
3. Support and secure work properly, as instructed in the Safety Instructions.
4. Use appropriate and required safety equipment, as instructed in the Safety Instructions.
5. Secure and maintain work area, as instructed in the Safety Instructions.
6. Run the drill very slowly, using light pressure, until the hole is started enough to keep the drill bit from slipping
out of it.
7. Apply pressure in a straight line with the bit. Use enough pressure to keep the bit biting but not so much as to
stall the motor or deflect the bit.
8. Hold the drill firmly with two hands to control its twisting action.
9. DO NOT CLICK THE TRIGGER OF A STALLED DRILL OFF AND ON IN AN ATTEMPT TO START IT.
DAMAGE TO THE DRILL CAN RESULT.
10. Minimize stalling on breakthrough by reducing pressure and slowly drilling through the last part of the hole.
11. Keep the motor running while pulling the bit out of a drilled hole. This will help reduce jamming.
