Frequently Asked Questions - 6841R MAKITA

How do I change the bit on the Makita 6841R screwdriver?

To change the bit, first ensure the tool is unplugged. Pull back the chuck sleeve (hexagonal chuck), insert the bit fully, then release the sleeve to lock it in place.

Can the Makita 6841R be used for drilling?

No, the 6841R is a dedicated screwdriver and is not designed for drilling. For drilling, use a Makita drill model.

What is the maximum screw size for the 6841R?

The 6841R can drive screws up to 6 mm in diameter and up to 50 mm in length, depending on the material.

How do I adjust the depth stop?

Loosen the depth stop collar, slide the stop to your desired depth, and tighten the collar securely. Test on a scrap piece first.

Why does the screwdriver stop suddenly?

This could be due to overload protection activating. Let the tool cool down for a few minutes. If it persists, check the carbon brushes or power supply.

How do I replace the carbon brushes?

Unplug the tool. Remove the brush caps on the sides of the motor housing. Pull out the worn brushes, insert new ones (same type), and replace the caps. Run for 5 minutes to seat brushes.

What type of oil should I use for maintenance?

No oiling is required for the 6841R. Just keep the vents clean and wipe the housing with a dry cloth. Do not use lubricants on the chuck or motor.

Is the Makita 6841R suitable for drywall?

Yes, with the appropriate depth stop and a drywall screw bit, the 6841R is excellent for driving drywall screws due to its adjustable depth control.

How do I change the rotation direction?

Locate the forward/reverse lever above the trigger. Slide it left for forward (tightening) and right for reverse (loosening). Do not switch while the motor is running.

What should I do if the screwdriver is sparking?

Some sparking at the brushes is normal, but excessive sparking indicates worn brushes or a dirty commutator. Unplug and inspect. Replace brushes if worn. If unsure, contact Makita service.

ENE033-1

Intended use

The tool is intended for screw driving in wood, metal and plastic.

ENF002-2

Power supply

The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. They are double-insulated and can, therefore, also be used from sockets without earth wire.

ENG905-1

Noise

The typical A-weighted noise level determined according to EN60745:

Sound pressure level ( L_pA ): 83 dB(A)

Sound power level ( L_WA ): 94 dB(A)

Uncertainty (K) : 3 dB(A)

Wear ear protection

ENG900-1

Vibration

The vibration total value (tri-axial vector sum) determined according to EN60745:

Work mode: screwdriving without impact

Vibration emission ( a_h ): 2.5 m/s ^2 or less

Uncertainty (K) : 1.5 m/s ^2

ENG901-1

- The declared vibration emission value has been measured in accordance with the standard test method and may be used for comparing one tool

with another.

- The declared vibration emission value may also be used in a preliminary assessment of exposure.

WARNING:

• The vibration emission during actual use of the power tool can differ from the declared emission value depending on the ways in which the tool is used.
• Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).

General Power Tool Safety Warnings

⚠ WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

GEB017-4

SCREWDRIVER SAFETY WARNINGS

1. Hold power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring or its own cord. Fasteners contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
2. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations.
3. Hold the tool firmly.
4. Keep hands away from rotating parts.
5. Do not touch the bit or the workpiece immediately after operation; they may be extremely hot and could burn your skin.

SAVE THESE INSTRUCTIONS.

⚠ WARNING:

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:

- Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.

Switch action

To start the tool, simply pull the switch trigger. Release the switch trigger to stop.

Reversing switch action

Fig.2

This tool has a reversing switch to change the direction of rotation. Depress the reversing switch lever from the A side for clockwise rotation or from the B side for counterclockwise rotation.

CAUTION:

• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool.

Hook

Fig.3

The hook is convenient for hooking the tool to your belt. It can be installed on either side of the tool.

Changing the installation position of hook allows two-way setting of 10 mm and 20 mm distance from the tool itself. The tool with hook can be hung on the waist belt, a maximum diameter 20 mm pipe etc.

To remove the hook, just remove the clamping screw. Place it on the tool and secure it with the clamping screw to install.

ASSEMBLY

Fig.4

Press the dust cover toward the plane bearing and pull out the bit. If the dust cover cannot be moved as far as the plane bearing, try it again after turning the bit slightly. To install the bit, insert it into the socket while turning it slightly. After installing, always make sure that the bit is securely held in place by trying to pull it out.

Fig.5

Setting for desired screw length

Fig.6

There are 3 positive-lock screw length settings. To obtain the desired setting, pull out the stopper base while depressing the lever until you see the number of the desired screw length (indicated on the plate) appear to rest on the very top edge of the casing. See the table below for the relation between the number indicated on the plate and the respective screw length ranges.

Number indicated on the plate	Screw length range
25/28 25 mm - 28 mm
32 28 mm - 35 mm
41 35 mm - 41 mm
