Setup

1. Charging the Battery

1. Connect the fast charger to a suitable power outlet.
2. Slide the 20V Li-ion battery into the charger until it clicks into place.
3. The charging indicator light on the charger will illuminate, typically red for charging and green for fully charged.
4. Allow the battery to charge completely before first use. Charging time may vary.
5. Once charged, disconnect the charger from the power outlet and remove the battery.

Note: It is recommended to fully charge new batteries before their initial use to ensure optimal performance and battery life.

2. Installing/Removing the Battery

• To Install: Align the battery with the base of the drill handle and slide it in until it clicks securely into place. Ensure it is firmly seated.
• To Remove: Press the battery release button (usually located on the sides of the battery pack) and slide the battery out of the drill handle.

3. Installing/Removing Drill Bits or Screwdriver Bits

1. Ensure the drill is switched off and the forward/reverse switch is in the center (locked) position to prevent accidental starting.
2. Rotate the chuck sleeve counter-clockwise to open the chuck jaws.
3. Insert the drill bit or screwdriver bit into the chuck, ensuring it is centered.
4. Rotate the chuck sleeve clockwise to tighten the chuck jaws firmly around the bit. Hand-tighten securely.
5. To Remove: Rotate the chuck sleeve counter-clockwise to loosen the jaws and pull the bit out.

Operating Instructions

1. Forward/Reverse Rotation

The forward/reverse switch (typically located above the trigger) controls the direction of rotation. Push it to the left for forward rotation (drilling/screwing in) and to the right for reverse rotation (removing screws). When the switch is in the center position, the trigger is locked, preventing accidental operation.

2. Speed Control

• Variable Speed Trigger: The trigger allows for variable speed control. Pressing the trigger lightly results in lower speeds, while pressing it fully increases the speed.
• Gear Selector: A gear selector switch (usually on top of the drill) allows you to choose between two speed ranges:
  • Gear 1 (Low Speed): For high torque applications like driving large screws or drilling large holes.
  • Gear 2 (High Speed): For faster drilling in softer materials or smaller holes.

3. Torque Settings (Clutch)

The torque adjustment ring (located behind the chuck) allows you to set the desired torque for screwing applications. Higher numbers indicate higher torque. When the set torque is reached, the clutch will disengage, preventing overtightening or stripping of screws. For drilling, set the ring to the drill symbol for maximum torque.

4. Mode Selection (Drilling, Hammer Drilling, Screwing)

The FERM FI20V offers three operating modes, selected via a ring behind the torque adjustment:

• Screwing Mode (⚙ symbol): Engages the clutch for controlled screw driving. Use with appropriate torque settings.
• Drilling Mode (★ symbol): Provides continuous rotation without clutch engagement or hammer action. Ideal for drilling into wood, metal, or plastics.
• Hammer Drilling Mode (⚒ symbol): Combines rotation with a hammering action. Essential for drilling into masonry, concrete, or brick. Use appropriate masonry drill bits.

5. General Operation Tips

• Always hold the drill firmly with both hands, especially during hammer drilling.
• Apply steady, even pressure. Do not force the drill.
• For drilling, start with a slow speed to create a pilot hole, then increase speed as needed.
• When drilling metal, use cutting oil to prolong bit life and improve cutting efficiency.
• Periodically clear debris from the work area to maintain visibility and prevent overheating.

Maintenance

Regular maintenance ensures the longevity and safe operation of your FERM Industrial Cordless Hammer Drill.

1. Cleaning

• Always disconnect the battery before cleaning.
• Wipe the tool's exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Use compressed air to clear dust and debris from ventilation openings and the chuck area.

2. Battery Care

• Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
• Do not store fully discharged batteries for extended periods. Charge them periodically if not in use.
• Avoid dropping or physically damaging the battery packs.

3. Storage

Store the drill, batteries, and charger in the provided storage case in a dry, secure location, out of reach of children. Ensure the battery is removed from the drill before storage.
