(2) Regarding the temperatures of the rechargeable
battery
The temperatures for rechargeable batteries are
as shown in the Table 2, and batteries that have
become hot should be cooled for a while before being
recharged.
Table 2 Recharging ranges of batteries
Rechargeable batteries
BCL1015
(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.
Table 3 Charging time (At 20°C)
Charger
Battery
1,5 Ah (3) Approx. 30 min. Approx. 40 min.
NOTE
The recharging time may vary according to the
ambient temperature.
4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after
use, and then keep it.
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 pilot lamp of the charger lights for 1 second,
does not light for 0.5 seconds (off for 0.5 seconds).
In such a case, fi rst let the battery cool, then start
charging.
○ When the pilot 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 chargers are 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.

1. How to use the screw-type mandrel (Fig. 6 (a))
Use the screw-type mandrel when using the felt
polishing wheel.
Keeping the wheel straight, screw it onto the thread of
the screw-type mandrel as far as the fl ange.
2. How to use the wheel mandrel (Fig. 6 (b))
Remove the screw in the end of the mandrel with a
fl athead screwdriver and attach the cutting wheel or
sanding disc.
3. How to use the drum mandrel (Fig. 6 (c))
A 60-grit sanding band is fi tted to the drum mandrel
when it leaves the factory.
Loosen the screw in the end of the mandrel with a
screwdriver to remove/attach the sanding band.
After attaching the sanding band, tighten the screw
securely.
4. Attach the tip tool to the grinder
Rotate the collet nut by hand while pressing the lock
button to further depress the lock button.
In this state, the shaft is locked and the collet nut can
be loosened or tightened. (Fig. 7)
To attach the tip tool, insert the tip tool as far as it will
go and tighten the collet nut securely.
To detach the tip tool, the collet nut can usually be
rotated by hand, though occasionally it may be tight.
If the collet nut is tight, use the provided collet spanner
to loosen it.
Iron powder on the collet nut, collet or shaft screw may
cause the collet nut to be diffi cult to rotate. (Fig. 8)
Be sure to remove any powder before attaching or
detaching the tip tool.
NOTE
Very occasionally, the tip tool may be diffi cult to detach
from the collet.
If this happens, with the collet nut loosened, press the
end of the tool lightly against a hard object. (Fig. 10)
5. Balance adjustment of the tip tool
After attaching the tip tool, operate the grinder at low
speed. If the balance is not right, follow the procedure
below to adjust the balance.
Loosen the collet nut while pressing the lock button.
Next, rotate the tip tool by 1/4 and tighten the collet nut.
Operate the grinder at low speed and check the
balance. If the balance is right, adjustment is
completed.
If the balance still is not right, detach the tip tool, the
collet nut and collet and re-attach them. If the tip tool
is still not balanced after several such attempts, check
for deformation or wear of the tip tool or deformation of
the collet. If worn or deformed, replace the tip tool or
collet.
