PRECAUTIONS ON USING IMPACT DRILL

1. Before drilling into a wall, floor or ceiling, thoroughly

confirm that no items such as electric cables or conduits are buried inside.

2. Always hold the body handle and side handle of the

power tool firmly. Otherwise the counterforce produced may result in inaccurate and even dangerous operation.English

Optional accessories are subject to change without notice. APPLICATIONS 䡬 By combined action of ROTATION and IMPACT: Boring, holes in concrete, marble, granite, tile and similar materials. 䡬 By ROTATION only: Boring holes in metals, wood and plastics.

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool Model VTP-18 VTV-18 Voltage (by areas)* (110V, 115V, 120V, 127V, 220V, 230V, 240V) Power input 640W* Speed change 1 2 1 2 No-load speed 1050/min 1800/min 0 – 1050/min 0 – 1800/min Capacity: Steel 13mm 8mm 13mm 8mm Concrete 18mm 10mm 18mm 10mm Weight (w/o cord) 2.3 kg will start operating immediately, which could cause serious injury.

When the work area is not near a power source. Use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as possible.

4. Fitting the Drill Bit:

Fit the drill bit into the chuck and use the chuck wrench to secure it, tightening the chuck by each of the three holes in turn.

5. Selecting the appropriate drill bit:

䡬 When boring concrete or stone: Use the drill bits specified in the Optional Accessories. 䡬 When boring metal or plastic: Use an ordinary metalworking drill bit. 䡬 When boring wood: Use an ordinary woodworking drill bit. However, when drilling. 6.5mm or smaller holes, use a metalworking drill bit.

6. High-speed/Low-speed changeover:

Prior to changing speed, ensure that the switch is in the OFF position, and the drill has come to a complete stop. To change speed, depress the shift lock and slide it in the appropriate direction, as indicated by the arrow in Fig. 1. The numeral “1” engraved in the drill body denotes low speed, the numeral “2” denotes high speed.

7. IMPACT to ROTATION changeover: (Fig. 2)

The Impact Drill can be switched from IMPACT (impact plus rotation) to ROTATION (rotation only) by simply turning the change ring. When boring concrete, stone, tile or similar hard materials, turn the change ring fully clockwise when viewed from the drill chuck side. The drill head impacts against the material while continuing to rotate. When boring metal, wood or plastic, turn the change ring fully counterclockwise. The drill simply rotates as an ordinary electric drill. CAUTION Do not use the Impact Drill in the IMPACT function if the material can be bored by rotation only. Such action will not only reduce drilling efficiency, but may also damage the drill tip. When changing over, ensure that the change ring is turned as far as it will go. SPECIFICATIONS

• Be sure to check the nameplate on product as it is subject to change by areas.5 English

8. Fixing the side handle:

Loosen the knob bolt on the side handle, and attach the side handle to the gear cover in a position convenient for drilling. Match the projecting part of the handle to the groove on the gear cover, and firmly tighten the knob bolt. To remove the side handle, loosen the knob bolt and rotate the handle. To attach a depth stopper on the side handle, insert the depth stopper into the U-shaped groove on the side handle, adjust the position of the depth stopper in accordance with the desired depth of the hole, and firmly tighten the knob bolt.

Drilling will NOT be accelerated by placing heavy pressure on the drill. Such action will only result in a damaged drill bit, decreased drilling efficiency, and/ or shortened service life of the drill.

2. Using a large diameter drill bit:

When using the larger diameter drill bit, the larger reactive force is applied on your arm. Be careful not to lose control of the drill because of this reactive force. To maintain firm control, establish a good foothold, hold the drill tightly with both hands, and ensure that the drill is vertical to the material being drilled.

3. When drilling completely through the material:

When the drill bit bores completely through the material, careless handling often results in a broken drill bit or damage to the drill body itself due to the sudden movement of the drill. Always be alert and ready to release the pushing force when penetrating the material.

4. Switch operation:

(1) VTP-18 : By pulling the trigger switch and depressing the stopper, the switch is held in the ON position for continuous operation. To turn the drill OFF, pull the trigger switch again and release. (2) VTV-18 : The rotational speed of the drill bit can be controlled by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the switch is pulled more. Continuous operation may be attained by pulling the trigger switch and depressing the stopper. To turn the switch OFF, pull the trigger switch again to disengage the stopper, and release the trigger switch to its original position.

5. Precautions on Boring

The drill bit may become overheated during operation; however, it is sufficiently operable. Do not cool the drill bit in water or oil.

6. Caution concerning immediately after use

Immediately after use, while it is still revolving, if the Drill is placed on a location where considerable ground chips and dust have accumulated, dust may occasionally be absorbed into the Drill mechanism. Always pay attention to this possibility.

Continued use of a worn and/or damaged drill bit will result in reduced drilling efficiency and may seriously overload the drill motor. Inspect the drill bit often and replace it with a new bit as necessary.

2. Inspecting the mounting screws:

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

3. Inspecting the carbon brushes (Fig. 3)

The motor employs carbon brushes which are consumable parts. Since excessively worn carbon brushes can result in motor trouble, replace the carbon brushes with new ones having the same carbon brush No. shown in the figure when they become worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

4. Replacing carbon brushes:

䡬 Disassembling: (1) Loosen the three screws on the handle cover, and remove the handle cover. Remove the holder plates, which keeps the brush holders in place, by removing the stopper screws. (2) Lift out the brush holders together with the carbon brushes, while being very careful not to forcibly pull the lead wires within the brush holders. (3) Withdraw the brush terminals, and remove the carbon brushes from the brush holders. 䡬 Reassembling: (1) Place new carbon brushes into the brush holders, and connect the brush terminals to the carbon brushes. (2) Return the brush holders and other parts to their original positions, as illustrated in Fig. 4, press the holder plates into position, and fasten it with the stopper screws. (3) Place the lead wire in the specified position. Be very careful not to allow the lead wire to contact the armature or rotating parts of the motor. (4) Replace the handle cover, while being careful to ensure it does not pinch the lead wire, and secure it firmly with the three screws. CAUTION Should the lead wire be pinched by the handle cover or come in contact with the armature or rotating parts of the motor, a serious danger of electric shock to the operator will be created. Exercise extreme caution in disassembling and reassembling the motor, follow the above procedure exactly. DO NOT attempt to disassemble any parts other than those necessary to effect replacement of the carbon brushes.

5. Maintenance of the motor

The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.
