[. . . ] Do not disassemble charger or battery cartridge; take it to a qualified serviceman when service or repair is required. To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning. Do not charge battery cartridge when temperature is BELOW 10°C (50°F) or ABOVE 40°C (104°F). Do not attempt to use a step-up transformer, an engine generator or DC power receptacle. [. . . ] 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. 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 justoperated 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. 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 the charging light goes out within one minute even after repeating this procedure a couple of times, the battery cartridge is dead. 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. 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. 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. Press the blade stopper pin and insert it through the hole in the wheel so that the wheel cannot revolve. If you charge a battery cartridge from a justoperated 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. Any of the following conditions indicates damage to the charger and/or battery cartridge. 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. If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will switch into its ``trickle charge (maintenance charge)'' mode and keep the battery cartridge fresh and fully charged. Loosen the bolt (A) on the depth guide with the hex wrench and move the base up or down. Always stop machine operation and charge the battery cartridge when you notice less machine power. CAUTION: After adjusting depth of cut and bevel cutting angle, be sure to tighten the bolts (A) and (B) securely. 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. [. . . ] 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. If the cutting action of the wheel begins to diminish, dress the cutting edge of the wheel using an old discarded coarse grit bench grinder wheel or concrete block. CAUTION: Always be sure that the machine is switched off and the battery cartridge is removed before carrying out any work on the machine. [. . . ]
