4. Disconnect the charger’s power cord from the receptacle.
5. Hold the charger firmly and pull out the battery. NOTE
Be sure to pull out the battery from the charger after use, and then keep it.
Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2­3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely exhausted. When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
(2) Avoid recharging at high temperatures. A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.
CAUTION If the battery is charged while it is heated because it
has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3 seconds (off for 0.3 seconds). In such a case, first let the battery cool, then start charging. When the charge indicator lamp flickers (at 0.2-second intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center. Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC18YSL3 is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.
PRIOR TO OPERATION
WARNING Before use, check the following. 1 to 2 should be checked before insert the battery.
1. Confirm that the vacuum switch is OFF. (Fig. 3) If, without knowing that the vacuum switch is ON, the battery is inserted, the appliance will start suddenly, causing unexpected accidents. The vacuum switch will be turned on by pushing “ON” and it will be turned off by returning it to “OFF”. Be sure to check that the vacuum switch is OFF.
2. Order of use for batteries When two batteries are installed, the battery with the least remaining power is used first until it is empty. Once empty, use is automatically switched over to the other battery. Use is still possible with a single installed battery.

NOTE When there is no more remaining power in a battery, immediately recharge the battery for convenient use later.
3. Check the filter Referring to “3. Attaching filters” in “HOW TO USE” the filter should be correctly attached.
CAUTION Water absorption amount will severely decline if the standardly equipped cloth filter is repeatedly used to absorb liquid. Use the separately sold nylon filter when repeatedly absorbing large amounts of water.
4. Inserting the battery (Fig. 4) As you pull on the clamp lever, open the battery guard. Next, match the battery with the unit’s groove and firmly press the battery in until you hear a click.
CAUTION Do not touch the terminals. Doing so may result in cutting your hand on the terminals or other unexpected injury.
5. Removing the battery (Fig. 4) When removing the battery from the unit, press the latches on both sides and slide the battery upwards to pull it out.
6. Switch operation (Fig. 5) During operation, the suction power will change each time the mode selection switch is pressed.
HOW TO USE
CAUTION Do not use the head top as a footstool or do not sit on it. Otherwise the appliance begins to move suddenly, causing an injury.
NOTE Handle the hose with care. Do not bend the hose by force, or do not trample it, or do not pull it to move the cleaner. Moreover, do not put away the hose as it is bent. Otherwise troubles such as its deformation may be caused.
1. Connecting the hose (Fig. 6) Press the attached hose into the suction opening of the tank until it clicks and connect it. When removing the hose, pull out the hose while pushing the button of the suction opening.
2. Attaching the plastic bag (Can be used without a plastic bag)
WARNING Be sure to turn off the appliance and remove the battery.
(1) Detach two clamps, pull up the head by the handle and remove it from the tank. (Fig. 7-a) Remove the filter and the filter cage inside the tank.
(2) Insert the supplied plastic bag between the inside of the tank and the bag guide. Insert the bag first along the bottom of the bag guide and then on both sides. Do not allow the edge of the plastic bag at “A” to overlap the upper surface of the tank. Insert the plastic bag all the way into both sides of the bag guide “B”. (Fig. 7-b)
(3) After spreading the plastic bag along the inside of the tank, draw the end of the plastic bag outside the tank. Following the directions on page 15 “Attaching filters”, insert the filter and the filter cage. At this point attach the filter so that the plastic bag is secured by the packing of the filter. (Fig. 7-c)

14

NOTE The edge of the plastic bag on the air intake should not
extend out of the top of the tank. (See Fig. 7-c) If all of the edge of the plastic bag extends out of the top of the tank, the air intake will be blocked, obstructing dust collection. When attaching the plastic bag, make sure that the slack portion of the plastic bag does not block the suction port inside the tank. (Fig. 7-d) 3. Attaching filters WARNING Be sure to attach the filter. (cloth filter, water filter or filter for dusts) Otherwise the motor will be damaged. When you collect fine dusts, such as siding powder and stone powder, use the optional paper filter. Since it is a cloth filter for dry and wet suction, do not remove it when you suck up liquids, such as water. Repeated water absorption with the cloth filter will significantly decrease the amount of water absorbed. When repeated water absorption in large volume is necessary, use the water filter. When using the water filter, do not attach the cloth filter. Do not suction dust with the water filter. NOTE If the cloth filter is wet, leave it to dry out of direct sunlight. Using the cloth filter when wet will conspicuously reduce the suction power. (1) Detach two clamps, pull up the head by the handle and remove it from the tank. (Fig. 7-a) Remove the filter and the filter cage inside the tank. (2) Attaching filters <Attaching the cloth filter (Fig. 8-a)> Insert the cloth filter so that the seam is on the other side of the hose inlet. <Attaching the water filter (Fig. 8-b)> When installing the water filter, make sure the cloth patch of the water filter is fitted to the suction opening of the hose. (3) Check that the filter packing is put on the mouth of the tank. (4) Check that the filter cage is on the bottom of the filter. NOTE When using the water filter, make sure the cloth filter is removed. 4. Attach the zoom pipe, master nozzles, etc. When it is used as a cleaner (Fig. 9) Connect in order of Hose (id 38 mm × 1.5 m long), zoom pipe and Master nozzle. Connection is done by pressing in the direction of the arrow. The suction mouth for crevices can also be attached depending on the application. 5. Connect power tools (Fig. 10) Connect in order of Hose (id 38 mm × 1.5 m long) and Adapter or Joint (C) (Optional Accessory). Connection is done by pressing in the direction of the arrow. NOTE (1) When you switch ON the unit after switching it OFF, the mode change-over switch will revert to its state prior to being switched OFF. The unit will revert to mode [2] when set at [3]. (2) Depending on the operating environment, the main unit’s temperature protective function may activate and switch off the unit. Should the unit switch off, refer to TROUBLESHOOTING (Page 18).

6. Cloth filter cleaning (Fig. 11) CAUTION
If the tank is filled with dusts, the suction power declines. Dump dusts as early as possible when they reach the half of the tank height. When the suction power declines during use, remove dusts in the following procedure: NOTE Since the cloth filter cleaning device operates when the suction power declines to some extent, it also operates in the following cases: When the suction mouth at the tip of the hose is closed. When the hose is clogged with foreign matter. To clean the cloth filter using a strong air flow. (1) Pull out the zoom pipe on the tip of the hose. (2) Block off the tip of the hose with your hand and turn the power switch ON. Next, press the dust button on the top of the head for approximately one second and release the button. Repeat three times and the suction power should recover. If the suction power is not recovered, the tank is almost filled with dusts. Dump dusts in the tank. 7. Dump dusts (Fig. 12) WARNING Be sure to turn off the vacuum switch and disconnect the battery. Put on a dust mask. Before removing the head, if the appliance is pushed on its side while the tank contains liquid, the liquid will get inside the motor or switch region, causing an electric shock or motor failure. CAUTION Do not impact the tank, the filter, or the head. Otherwise they will be deformed or damaged. Although it is based on the amount of suction of dusts and liquids, dump dusts and liquids in the tank at least once a day and keep the appliance, the filter, etc. clean. Otherwise suction power fall, motor failure, bad smell or rusting may be caused. Do not hold the clamps when you dump dusts in the tank. Otherwise the clamps may be damaged. NOTE When removing the plastic bag filled with dust from the tank, make sure the bag does not become caught on parts inside the tank. Empty the plastic bag regularly so that it does not become excessively filled with dust. Do not tilt the tank with accessories (Zoom pipe, Master nozzle, etc.) inserted in the head or in the tank. Otherwise any part may be damaged. (1) Detach two clamps, pull up the head by the handle and remove it from the tank. (Fig. 7-a) Remove the filter and the filter cage inside the tank. (2) Lightly striking the inner side of the cloth filter several times, remove dusts attached to the cloth filter. (3) Tilt the tank and dump dusts. (4) Attach the cloth filter, the filter cage, the head, and the clamp in the initial positions. <When using the plastic bag> Drop the dust which has collected outside the filter into the plastic bag, and after removing the filter and filter cage, remove the plastic bag with the dust from the tank and dispose the bag.

8. Transportation and storage (1) How to use the handle (Fig. 13)
When carrying or moving the appliance, hold the handle of the head part. When you do not use the handle, put it in the head part. (2) Fixation and release of the caster (Fig. 14) By lowering the lever of the caster with the brake, the rotation of the wheel is fixed. When releasing the fixed wheel, raise the lever. When moving with the appliance on a vehicle, fix the caster to retain the appliance. However, when you move the appliance, check that the caster is released, or the caster will be damaged. (3) Tool box assembly (Fig. 15) (4) Storing the appliance during breaks (Fig. 16) Anytime you stop work or take a break from cleaning, you can quickly store the unit by hooking the zoom pipe to the pipe holder (the hole at the top of the unit) so that it stands. (5) When the appliance is stored (Fig. 17) After removing the suction opening and hose, hook the zoom pipe to the pipe holder so that it stands. Store the master nozzle, crevice nozzle and battery in the tool box. NOTE When the attachments are stored in the appliance, do not apply any excess force to the attachments. 9. How to attach the paper filter (Optional) (Fig. 18) WARNING Be sure to turn off the appliance and remove the battery. When using a paper filter, use it in combination with the standard cloth filter. If the paper filter gets torn, dust may get inside the motor, causing abnormal noise or fire due to overheating. CAUTION When using a paper filter, avoid sucking in liquids such as water or wet dust, as this may lead to tearing of the filter. (1) Open the paper filter horizontally so that the suction hole in the paper filter is over the top of the tank. (2) Before attaching the filter to the appliance, bend the two folds in the cardboard approx. 90° in the direction of the arrow. (3) Match the suction hole in the paper filter with the suction opening of the appliance. Insert the filter in the direction of the arrow as shown in the illustration, so that the cardboard of the paper filter goes past the stopper on the suction opening.

WARNING With the float working, do not continue operation.
Otherwise the temperature of the motor may rise abnormally causing troubles such as deformation of parts or motor burnout. Avoid sucking in foaming liquid such as detergent or foams. Before the float works, foams may spurt from the air outlet. If you continue to use the appliance as it is, it will lead to electric shock or failure.
ABOUT REMAINING BATTERY INDICATOR
Remaining battery power can be verified with either the battery or with the cleaner itself. (Fig. 19) NOTE The reading for the remaining battery power may differ
on the battery from that of the cleaner. Use the remaining batter power as a guideline since
the readings may somewhat differ due to surrounding temperature or battery feature.

MAINTENANCE AND INSPECTION
WARNING For inspection and maintenance, be sure to turn off the
vacuum switch and disconnect the battery. Do not work with wet hands. May cause electric shock
or injuries. 1. Maintenance of filter NOTE Since a filter is a consumable, we recommend you to
prepare spares. The cloth filter should simply be tapped even if it is
considerably clogged. Strong brushing will shorten its life. Do not hurl a filter. May break its resin part. A clogged filter will decrease the suction power remarkably. Tap the inner side of the filter to drop off dusts regularly. 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. 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. 4. Inspection of terminals (tool and battery) Check to make sure that swarf and dust have not collected on the terminals. On occasion check prior, during and after operation. CAUTION Remove any swarf or dust which may have collected on the terminals. Failure to do so may result in malfunction. 5. Check for Dust Dust may be removed with a soft cloth or a cloth dampened with soapy water. Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics. 6. Storage Storing in a place below 40°C and out of the reach of children. NOTE Storing lithium-ion batteries. Make sure the lithium-ion batteries have been fully charged before storing them. Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, significantly reducing battery usage time or rendering the batteries incapable of holding a charge. However, significantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to five times. If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.
