How To Use DeWalt DCD791D2 Drill
- Before inserting the battery pack, Plug the charger into an appropriate outlet. 11 Fig. C 10
- The red charging light will start blinking continuously, indicating that the charging process has begun while you insert the battery pack 11 into the charger, make sure that the battery pack is adjusted in the charger.
- If the battery is charged fully, then it will be indicated by the red light remaining ON continually. After pushing the battery release button 10 on the battery pack, you can remove the battery pack from the charger. If the battery pack is totally charged, it may be used at this time or can be left in the charger.
NOTE: Charge the battery pack fully before first use to ensure maximum performance and life of lithium-ion battery packs.
Variable Speed Trigger Switch (Fig. A)
To turn the tool on, press the trigger switch 1. To turn the device off, release the trigger switch.
As the machine is equipped with brakes so the chuck will automatically stop as soon as you fully release the trigger switch.
NOTE: It is not recommended to continuously use in variable speed range. It should be avoided as it may damage the switch.
Forward/Reverse Control Button (Fig. A)
Press the forward/reverse control button on the right side of the tool to choose forward rotation, from the trigger switch. To select the reverse, depress the forward/backward control button on the left side of the device.
The middle position of the control button locks the device in a distant place.
A forward/reverse control button 2 selects the direction of the power tool and also serves as a lock-off button.
NOTE: The first time the tool is run after changing the direction of rotation, you may hear a click on startup. This is common and does not mean any problem.
Drilling (Fig. J)
NOTICE: If drilling thin material, use a block of wood as a backup to prevent loss to the material.
- Choose the desired speed/torque limit using the gear shifter to balance the speed and torque to the planned operation. To the drill symbol, turn the collar 3.
- Use sharp and fine drill bits only. Use carbide-tipped bits rated for percussion drilling.
- For MASONRY purposes such as brick, cement, cinder block, etc. Always apply enough pressure in a straight line with the bit to keep drill biting, but do not try to push hard enough to deflect the bit stall the motor.
- Hold the tool firmly with both hands to control the twisting action of the drill. Grip the drill with one hand on the handle and one hand on the battery pack if the device is not equipped with side handle.
WARNING: Grip the drill firmly to control the twisting action and avoid injury. The drill may stall if causing an overloaded, sudden twist. Always expect the stall.
- To reduce overloaded, stalling, reduce pressure on the drill or breaking through the material, try to ease the bit by the last fractional section of the hole.
- To stop jamming, let the motor rolling when you’re pulling the bit back out of a drilled hole.
Torque Adjustment Collar (Fig. A)
The power is equipped with an adjustable torque screw-driving mechanism for removing and driving a wide array of fastener shapes and areas and in some models of power tools, a hammer mechanism for drilling into masonry.
Circling the collar 3 numbers, a hammer symbol and in some models a drill bit symbol. To set the clutch and to deliver a torque range these numbers are used. As much as high the collar number will be, higher torque and the larger the fastener can be driven. Rotate till the desired number aligns with the arrow to select any of the numbers.
NOTE: The torque adjustment collar is only engaged and involved during the screw-driving mode. It is not engaged and involved during drilling or hammer drill modes.
Power Tool Use and Care:
- Avoid adjusting the too, use the correct power tool for your application. Do not force the power tool. The right power tool will do the job better and will be safer for the tasks for which it is designed.
- Avoid using the power tool if the (on and off) switch does not work correctly. The power tools that cannot be controlled with the switch is deadly and hazardous and must be repaired.
- Before performing any adjustments, changing accessories, or storing power tools, remove the battery pack from the power tool. Such preventive and safety measures minimize the risk of automatically starting the power tool accidentally.
- Do not allow persons who are unfamiliar with the power tool or do not know these instructions to operate the power tool. Power tools are hazardous and dangerous in the hands of untrained users — store unused power tools out of the range of children.
- Inspect for the misalignment of the tool or binding of moving parts, damage of parts, or other conditions that can affect the power tool’s operation. Maintain power tools. If the power tool is found damaged, have the power tool repaired before use. Poorly maintained power tools cause many accidents.
Screw Driving (Fig. K):
- Choose the desired speed/torque range by the gear shifter to match the speed and torque to the desired operation.
- Turn the torque fixing collar 3 to the wanted position.
NOTE: Use the minimum torque setting needed to seat the fastener at the desired depth — as low as the number, lesser will be the torque output.
- Insert the wanted fastener accessory into the chuck as you would any drill bit.
- Do some practice runs in scrap or on unwanted areas of the workpiece to learn the proper manner of the torque adjustment collar.
- Try to always start with lower torque settings, then advance to higher torque settings to avoid damage to the workpiece or fastener.
GENERAL POWER TOOL SAFETY WARNINGS

• Another way to figure out a torque rating of a Dewalt drill is to go to Dewalt's EU site, pick the United Kingdom and look at the specs. They list both torque specs in this case. MAX is 70 nm soft is 27 nm converting to 619.55 in-lb and 238.97 in-lb. • Hard torque is instant torque delivered. Usually at the start of an application; whereas, soft torque is applied throughout the application like when driving a screw. Coming to my DeWalt dcd791d2 review overall the product is good as compared to the price. It takes about 1-1/2 hours for each battery. The light blinks when it's done. They are excellent, and you will like them with the 20v drill. 530 in-lb. Adjustable. VERY powerful and yet small drill.
