Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict severe injury. It is not necessary to drain the battery pack completely before recharging. Lithium-ion battery packs have no “memory” and can be recharged at any time.
OPERATION FULL CAPACITY TO CHARGE A fully discharged battery pack with a temperature between 32° F (0° C) and 150° F (65° C) will charge in about an hour. Charge the 24 Volt lithium-ion battery pack only with the charger provided. � Connect the charger to a power supply. NOTE:iIf needed, the charger can operate with most generators and inverters rated at 300 Watts or higher.
OPERATION LED FUNCTION OF CHARGER See Figure 5. LED INDICATOR BATTERY PACK RED LED GREEN LED ACTION Charging Fast charging ON OFF Charges in 1 hour Charging Deeply Discharged ON OFF Charger pre-charges battery until normal voltage is reached, then begins fast charge mode. May take longer than 1 hour to fully charge.
OPERATION TO INSTALL BATTERY PACK See Figure 6. Lock the switch trigger on the drill by placing the direction of rotation (forward/reverse/center lock) selector in center position. Place the battery pack in the drill. Align the raised rib on the battery pack with the groove inside the drill. Make sure the latches on each side of the battery pack snap in place and battery pack is secured in the drill before beginning operation.
OPERATION DIRECTION OF ROTATION SELECTOR DRILL BIT (FORWARD/REVERSE/CENTER LOCK) See Figure 7. The direction of bit rotation is reversible and is controlled by a selector located above the switch trigger. With the drill held in normal operating position, the direction of rotation selector should be positioned to the left of the switch trigger for drilling. The drilling direction is reversed when the selector is to the right of the switch trigger.
OPERATION TWO-SPEED GEAR TRAIN (HI-LO) TWO-SPEED GEAR TRAIN See Figure 9. The drill has a two-speed gear train designed for drilling or driving at LO (1) or HI (2) speeds. A slide switch is located on top of the drill to select either LO (1) or HI (2) speed. When using drill in the LO (1) speed range, speed will decrease and unit will have more power and torque. When using drill in the HI (2) speed range, speed will increase and unit will have less power and torque.
OPERATION SELECTING DRIVE, DRILL, OR HAMMER SETTING 3 2 See Figure 11. Select the option that best matches the type of bit, fastener, and material you will be using. Choose your application Choose the correct speed: LO (1) or HI (2) Choose the correct mode: Drill, Drive or Hammer. TORQUE ADJUSTMENT See Figure 12.
OPERATION INSTALLING BITS DRILL BIT See Figure 13. Lock the switch trigger by placing the direction of rotation selector in the center position. Open or close the chuck jaws to a point where the opening is slightly larger than the bit size you intend to use. Also, raise the front of the drill slightly to keep the bit from falling out of the chuck jaws. Insert the drill bit. CHUCK JAWS WARNING: Make sure to insert the drill bit straight into the chuck jaws.
OPERATION USING THE AUXILIARY HANDLE ASSEMBLY See Figure 15. An auxiliary handle assembly is packed with the drill for ease of operation and to help prevent loss of control. The handle can be rotated 360°, and it can also be mounted on the opposite side for left hand use. To adjust the auxiliary handle assembly: Loosen the handle assembly by turning the handle counterclockwise. Rotate the handle assembly to the desired operating position. Securely tighten by turning the handle assembly clockwise.
OPERATION WOOD DRILLING� MASONRY DRILLING Select drill mode.� Begin drilling at a very low speed to prevent the bit from slipping off the starting point. Increase the speed as the drill bit bites into the material.� When drilling through holes, place a block of wood behind the workpiece to prevent ragged or splintered edges on the back side of the hole.� Turn mode change ring to the hammer drill icon to select hammer mode.� Apply light pressure and medium speed for best results in brick.
