For 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.

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.
