Always switch off the machine before insertion or removal of the battery cartridge.

To remove the battery cartridge, pull out the set plate on the machine and grasp both sides of the cartridge while withdrawing it from the machine.

To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Snap the set plate back into place. Be sure to close the set plate fully before using the machine.

Do not use force when inserting the battery car- tridge. If the cartridge does not slide in easily, it is not being inserted correctly. Charging For 4190D (Fig. 3)

1. Plug the battery charger into your power source.

2. Insert the battery cartridge so that the plus and

minus terminals on the battery cartridge are on the same sides as their respective markings on the battery charger. Insert the cartridge fully into the port so that it rests on the charger port floor.

3. When the battery cartridge is inserted, the charg-

ing light color will flash in red color and charging will begin.

4. When charging is completed, the charging light

goes out. The charging time is as follows: Battery 7000, 7100, 7120, 9000, 9100, 9100A, 9120: approx. 60 minutes.

5. If you leave the battery cartridge in the charger

after the charging cycle is complete, the charger will switch into its ‘‘trickle charge (maintenance charge)’’ mode.

6. After charging, remove the battery cartridge from

the charger and unplug the charger from the power source. Battery type Capacity (mAh) Number of cells 9000 1,300 8 CAUTION:

The battery charger is for charging Makita battery cartridge. Never use it for other purposes or for other manufacturer’s batteries.

When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of time, it may not accept a full charge. This is a normal condition and does not indicate a problem. You can recharge the battery cartridge fully after discharging it completely and recharging a couple of times.

When you charge a battery cartridge from a just- operated machine or a battery cartridge which has been left in a location exposed to direct sunlight or heat for a long time, let it cool off. Then re-insert it and try to charge it once more.

When you charge a new battery cartridge or a battery cartridge which has not been used for a long period, sometimes the charging light will go out soon. If this occurs, remove the battery cartridge and re-insert it. If the charging light goes out within one minute even after repeating this procedure a couple of times, the battery cartridge is dead. Replace it with a new one. 4190D (E) (’100. 3. 15) 5For 4190DB (Fig. 4) Plug the battery charger into your power source. Insert the battery cartridge so that the plus and minus terminals on the battery cartridge are on the same sides as their respective markings on the battery charger. Insert the cartridge fully into the port so that it rests on the charger port floor. When the battery cartridge is inserted, the charging light will come on and charging will begin. The charg- ing light will keep lighting up steadily during charging. When charging is completed, the charging light goes out. The charging time is approx. 100 minutes. After charging, unplug the charger from the power source. Battery type Capacity (mAh) Number of cells 9033 2,200 8 CAUTION:

If you charge a battery cartridge from a just- operated machine or a battery cartridge which has been left in a location exposed to direct sunlight for a long time, the charging light may flash in red color. If this occurs, wait for a while. Charging will begin after the battery cartridge cools.

Any of the following conditions indicates damage to the charger and/or battery cartridge. Ask your Makita Authorized or Factory Service Center to check them.

1) The charging light does not light up or flash (red)

when the battery is inserted in the charger port.

2) Charging is not completed at even more than

three hours after red light comes ON at start of charging. Trickle charge (Maintenance charge) If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will switch into its ‘‘trickle charge (main- tenance charge)’’ mode and keep the battery car- tridge fresh and fully charged. Tips for maintaining maximum battery life

1. Charge the battery cartridge before completely

discharged. Always stop machine operation and charge the battery cartridge when you notice less machine power.

2. Never recharge a fully charged battery cartridge.

Overcharging shortens the battery service life.

3. Charge the battery cartridge with room tempera-

ture at 10°C – 40°C (50°F – 104°F). Let a hot battery cartridge cool down before charging it. Installing water supply Attach the tank holder on the tank. The tank holder should be attached around the portion shown with the dotted line. Tighten the screw (A) to the extent that the tank can still turn within the tank holder. (Fig. 5) Attach the tank holder onto the motor housing. Tighten the screw (B) securely. (Fig. 6) Connect the cap on the end of the polyvinyl tube to the mouth of the tank. Turn the tank clockwise when making the connection. Then tighten the screw (A) securely to secure the tank. (Fig. 7) CAUTION: If you find the polyvinyl tube is bent like a ‘‘V’’ or has been strained excessively after installing the water supply, loosen the screw (B) and adjust the position of the tank to alleviate the bent, pinched or strained condition. Installing or removing diamond wheel (Fig.8&9) Important: Always be sure that the machine is switched off and the battery cartridge is removed before installing or removing the wheel. To install the wheel, first loosen the bolt with the hex wrench and remove the bolt and the flange. Then mount the wheel, the flange and the bolt. The wheel should be mounted with the Makita name on the flange side. Press the blade stopper pin and insert it through the hole in the wheel so that the wheel cannot revolve. Use the hex wrench to tighten the bolt securely. To remove the wheel, follow the installation procedure in reverse. CAUTION:

When installing the wheel, be sure to tighten the bolt securely.

Use only the Makita hex wrench to install or remove the wheel. Hex wrench storage (Fig. 10) When not in use, the hex wrench can be conveniently stored. Adjusting depth of cut (Fig. 11) Loosen the bolt (A) on the depth guide with the hex wrench and move the base up or down. At the desired depth of cut, secure the base by tightening the bolt (A). Bevel cutting (Fig. 12) Loosen the bolt (A) on the depth guide and the bolt (B) on the bevel scale plate with the hex wrench. Set for the desired angle (0 – 45°) by tilting accordingly, then tighten the bolts (A) and (B) securely. CAUTION: After adjusting depth of cut and bevel cutting angle, be sure to tighten the bolts (A) and (B) securely. Sighting (Fig. 13) For straight cuts, align the edge of the base with your cutting line on the workpiece. For 45° bevel cuts, align the notch in the front of the base with it. CAUTION: When making bevel cuts, view the cutting line on the workpiece through the window in the blade case in order to cut more accurately. If you have difficulty seeing it because of the water tank, adjust the posi- tion of the tank by tilting it backward slightly.

4190D (E) (’100. 3. 15)Switch action (Fig. 14) CAUTION: Before inserting the battery cartridge into the machine, always check to see that the switch trigger actuates properly and returns to the ‘‘OFF’’ position when released. To prevent the trigger from being accidentally pulled, a lock-off lever is provided. To start the machine, slide the lock-off lever in the direction of the arrow and pull the trigger. Release the trigger to stop. Water supply (Fig. 15) Remove the cap on the tank and fill through the hole. Recap the tank. Be sure that the water cock is turned off when filling the tank with water. CAUTION: When filling the tank with water, be careful not to let the machine get wet. Operation (Fig. 16) Hold the machine firmly. Set the base plate on the workpiece to be cut without the wheel making any contact. Then turn the machine on and wait until the wheel attains full speed. Feed water to the wheel by adjusting the water cock to obtain a gentle flow of water. Move the machine forward over the workpiece surface, keeping it flat and advancing smoothly until the cutting is completed. Keep your cutting line straight and your speed of advance uniform. For fine, clean cuts, cut slowly. (When cutting glass plate 5 mm thick, cut at about 250 mm/min. When cutting tile 10 mm thick, cut at about 300 mm/min.) Also slow down as you complete a cut to avoid breaking or cracking the workpiece being cut. CAUTION:

Be sure to hold the workpiece firmly down on a stable bench or table during operation.

Do not twist or force the machine in the cut, or the motor may be overloaded or the workpiece may break.

Do not use the machine with the wheel in an upward or sideways position.

When cutting glass plate, it is recommended to attach a rubber plate (optional accessory) on the base of the machine to prevent the workpiece surface from being scratched.

The wheel for Model 4190D/DB is a wet-type wheel for glass and tile applications. Be sure to feed water to the wheel during operation.
