HR2022 - Drill MAKITA - Free user manual and instructions

USER MANUAL HR2022 MAKITA

• Due to our continuing program of research and devel- opment, the specifications herein are subject to change without notice.

• Note: Specifications may differ from country to country. Intended use The tool is intended for hammer drilling and drilling in brick, concrete and stone. It is also suitable for drilling without impact in wood, metal, ceramic and plastic. 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 in accordance with European Standard and can, therefore, also be used from sockets without earth wire. Safety hints For your own safety, please refer to the enclosed safety instructions.

ADDITIONAL SAFETY RULES

1. Hold tools by insulated gripping surfaces when

performing an operation where the cutting tool may contact hidden wiring or its own cord. Con- tact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

2. Wear ear protertors when using the tool for

extended periods. Prolonged exposure to high intensity noise can cause hearing loss.

3. Wear a hard hat (safety helmet), safety glasses

and/or face shield. It is also highly recom- mended that you wear a dust mask, and thickly padded gloves.

4. Be sure the bit is secured in place before opera-

5. Under normal operation, the tool is designed to

produce vibration. The screws can come loose easily, causing a breakdown or accident. Check tightness of screws carefully before operation.

6. In cold weather or when the tool has not been

used for a long time, let the tool warm up for a while by operating it under no load. This will loosen up the lubrication. Without proper warm- up, hammering operation is difficult.

7. Always be sure you have a firm footing.

Be sure no one is below when using the tool in high locations.

8. Hold the tool firmly with both hands.

9. Keep hands away from moving parts.

10. Do not leave the tool running. Operate the tool

only when hand-held.

11. Do not point the tool at any one in the area when

operating. The bit could fly out and injure some- one seriously.

12. Do not touch the bit or parts close to the bit

immediately after operation; they may be extremely hot and could burn your skin. SAVE THESE INSTRUCTIONS. OPERATING INSTRUCTIONS Side grip (auxiliary handle) (Fig. 1) Always use the side grip to ensure operating safety. Install the side girp so that the teeth on the grip fit in between the protrusions on the tool barrel. Then tighten the grip by turning clockwise at the desired position. It may be swung 360° so as to be secured at any position.6 Installing or removing the bit CAUTION: Always be sure that the tool is switched off and unplugged before installing or removing the bit. Clean the bit shank and apply bit grease before installing the bit. (Fig. 2) Insert the bit into the tool. Turn the bit and push it in until it engages. (Fig. 3) After installing, always make sure that the bit is securely held in place by trying to pull it out. To remove the bit, pull the chuck cover down all the way and pull the bit out. (Fig. 4) Depth gauge (Fig. 5) The depth gauge is convenient for drilling holes of uni- form depth. Loosen the side grip and insert the depth guage into the hole in the side grip. Adjust the depth gauge to the desired depth and tighten the side grip. NOTE: The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing. Switch action (Fig. 6) CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released. For Model HR2020, HR2020X and HR2021 To start the tool, simply pull the switch trigger. Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop. For continuous opera- tion, pull the switch trigger and then push in the lock but- ton. To stop the tool from the locked position, pull the switch trigger fully, then release it. For Model HR2022 To start the tool, simply pull the switch trigger. Release the switch trigger to stop. For continuous operation, pull the switch trigger and then push in the lock button. To stop the tool from the locked position, pull the switch trig- ger fully, then release it. Reversing switch action (Fig. 7) For Model HR2020 and HR2020X This tool has a reversing switch to change the direction of rotation. Move the reversing switch lever to the A side for clockwise rotation or 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.

• When you operate the tool in counterclockwise rotation, the switch trigger is pulled only halfway and the tool runs at half speed. For counterclockwise rotation, you cannot push in the lock button. Selection action mode (Fig. 8) This tool employs an action mode changing knob. Select one of the two modes suitable for your work needs by using this knob. For rotation only, turn the knob so that the arrow on the knob points toward the

symbol on the tool body. For rotation with hammering, turn the knob so that the arrow on the knob points toward the

sym- bol on the tool body. CAUTION:

• Always set the knob fully to your desired mode symbol. If you operate the tool with the knob positioned half- way between the mode symbols, the tool may be dam- aged.

• Use the knob after the tool comes to a complete stop. Torque limiter The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the bit will stop turning. CAUTION:

• As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool.

• Hole saws cannot be used with this tool. They tend to pinch or catch easily in the hole. This will cause the torque limiter to actuate too frequently. Hammer drilling operation Position the bit at the desired location for the hole, then pull the 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. CAUTION: There is tremendous and sudden twisting force exerted on the tool/bit at the time of hole breakthrough, 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 con- trol of the tool and potentially severe injury. Bit grease Coat the bit shank head beforehand with a small amount of bit grease (about 0.5 – 1 g). This chuck lubrication assures smooth action and longer service life. Blow-out bulb (Fig. 9) Use the blow-out bulb to clean out the hold. Dust cup (Fig. 10) Use the dust cup to prevent dust from falling over the tool and on yourself when performing overhead drilling opera- tions. Attach the dust cup to the bit as shown in Fig. 10. The size of bits which the dust cup can be attached to is as follows. Bit diameter (mm) Dust cup 5 6 – 14.5 Dust cup 9 12 – 167 Drilling in wood or metal (Fig. 11 and 12) Use the optional drill chuck assembly (standard equip- ment for Model HR2020X). When installing it, refer to “Installing or removing drill bit” described on the previous page. Hold the ring and turn the sleeve counterclockwise to open the chuck jaws. Place the bit in the chuck as far as it will go. Hold the ring firmly and turn the sleeve clockwise to tighten the chuck. To remove the bit, hold the ring and turn the sleeve coun- terclockwise. Set the action mode changing knob to “rotation only”. You can drill up to 13 mm diameter in metal and up to 32mm diameter in wood. CAUTION:

• Never use “rotation with hammering” when the drill chuck assembly is installed on the tool. The drill chuck assembly may be damaged. Also, the drill chuck will come off when reversing the tool. (For Model HR2020 and HR2020X)

• 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 perfor- mance and shorten the service life of the tool.

• There is a tremendous twisting force exerted on the tool/bit at the time of hole breakthrough. 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.

• When performing diamond core drilling operation, always set the change lever to the M position to use

action. If performing diamond core drilling operation with

rotation with hammering

• Plastic carrying case

• Schlüsselloses Bohrfutter

• Dust extractor attachment

• Diamond core bit (Dry type)
