Frequently Asked Questions - HP1641FJ MAKITA

How do I change the direction of rotation on the Makita HP1641FJ?

Use the reversing switch located near the trigger. Slide it to position A for clockwise rotation (driving screws) or position B for counterclockwise rotation (removing screws). Always wait until the tool comes to a complete stop before changing direction to avoid damage.

What is the maximum drilling capacity in concrete?

The Makita HP1641FJ can drill up to 16 mm in concrete when using a tungsten-carbide tipped bit in hammer mode.

How do I select between hammer drilling and normal drilling?

Slide the action mode changing lever to the right (symbol with a hammer) for rotation with hammering, or to the left (symbol with a drill) for rotation only. Ensure it is fully engaged to avoid damage.

Can I use the drill without the side grip?

It is highly recommended to always use the side grip (auxiliary handle) for safety, especially during hammer drilling. The side grip provides better control and reduces the risk of injury from sudden torque.

How do I install a drill bit in the keyless chuck?

Hold the ring and turn the sleeve counterclockwise to open the chuck jaws. Insert the bit as far as it will go, then hold the ring firmly and turn the sleeve clockwise to tighten. To remove, reverse the process.

What maintenance is required for the HP1641FJ?

Regularly clean the tool with a dry cloth, especially the lamp lens. Do not use gasoline or solvents. For internal maintenance (carbon brushes, repairs), always take the tool to a Makita Authorized Service Center to maintain safety and reliability.

Why does my drill bit get stuck and how can I remove it?

If the bit gets stuck, set the reversing switch to reverse rotation and gently pull the trigger to back it out. Hold the tool firmly to prevent abrupt movement. Ensure the tool is unplugged before attempting manual removal.

What is the purpose of the depth gauge?

The depth gauge allows you to drill holes of uniform depth. Loosen the side grip, insert the depth gauge into the hole, adjust to desired depth, then tighten the side grip. It cannot be used if it strikes the tool body.

Is the Makita HP1641FJ double insulated?

Yes, it is double insulated (Class II) and can be used from sockets without an earth wire. Always check that the voltage matches the nameplate.

What should I do if the tool does not start?

First, ensure the tool is plugged in and the power supply is working. Check that the reversing switch is fully set to either position. If the switch trigger cannot be depressed, the reversing switch may not be fully engaged. If issues persist, contact a Makita service center.

NOTE:

- The depth gauge cannot be used at the position where the depth gauge strikes against the tool body.

OPERATION

Hammer drilling operation

Fig.9

CAUTION:

- There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury.

When drilling in concrete, granite, tile, etc., move the action mode changing lever to the position of symbol to use "rotation with hammering" action.

Be sure to use a tungsten-carbide tipped bit.

Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole.

Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed.

Blow-out bulb (optional accessory)

Fig.10

After drilling the hole, use the blow-out bulb to clean the dust out of the hole.

Drilling operation

When drilling in wood, metal or plastic materials, move the action mode changing lever to the position of Ⓞ symbol to use "rotation only" action.

Drilling in wood

When drilling in wood, the best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece.

Drilling in metal

To prevent the bit from slipping when starting a hole, make an indentation with a center-punch and hammer at the point to be drilled. Place the point of the bit in the indentation and start drilling.

Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry.

CAUTION:

- Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the

tool performance and shorten the service life of the tool.

• There is a tremendous force exerted on the tool/bit at the time of hole break through. Hold the tool firmly and exert care when the bit begins to break through the workpiece.
• A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool may back out abruptly if you do not hold it firmly.
• Always secure small workpieces in a vise or similar hold-down device.

MAINTENANCE

CAUTION:

- Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.

NOTICE:

- Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection and replacement, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
