(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, fi rst let the battery cool,
then start charging.
○ When the charge indicator lamp fl ickers (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 confi rm 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.

*2 WARNING
Before use, be sure to tighten the wheel nut with the
included wrench.
Failure to tighten could result in the wheel nut
loosening when the brake is activated during a stop.
NOTE
The wheel washer is specifi cally for this product. Do
not use it for any other product.
*3 Grinding angle and grinding method
Press down the machine evenly on the surface and
move back and forth so that the surface of the workpiece
does not become too hot.
Rough grinding: position the machine at an angle of
15°–30° for the best working results.
When the grinding stone is new, its corner may dig in
when it is pushed forward, so pull back during use.
(Fig. 10-a)
Once the wheel edge is worn, the workpiece can be
ground in both directions. (Fig. 10-b).
*4 Cutting work
Always work against the run of the disc. Otherwise there
is the danger of the machine kicking back from the cut
out of control. Guide the machine evenly at a speed
suitable for the material being processed. Do not tilt,
apply excessive force or sway from side to side.
MAINTENANCE AND INSPECTION
WARNING
Be sure to turned off the switch and remove the battery
before maintenance and inspection.
1. Inspecting the depressed center wheel
Ensure that the depressed center wheel is free of cracks
and surface defects.
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. Filter cleaning and inspection (Fig. 12)
WARNING
Wear protective glasses and a dust mask when cleaning
the fi lter with an air gun.
Failure to do so may result in inhalation or exposure of
the eyes to debris or dust.
After use, remove any debris or dust adhered to the fi lter
using a soft brush. Check the fi lter periodically to ensure that
it is free of scratching, chipping, or tearing. Replace with a
new fi lter if the fi lter is damaged in any way.
NOTE
○ If the mesh is clogged and the debris or dust cannot be
removed, detach the fi lter and clean it with an air gun,
etc.
○ After cleaning, make sure to securely attach the fi lter.
4. 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.
NOTE
In order to expel debris and dust, periodically run the
motor with no load.
5. 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.
6. Cleaning on the outside
When the cordless disc grinder is stained, wipe with a
soft dry cloth or a cloth moistened with soapy water. Do
not use chloric solvents, gasoline or paint thinner, for
they melt plastics.
7. Storage
Store the power tool and battery in a place in which
the temperature is less than 40°C and out of reach of
children.
