EINHELL TC-AG 18/115 Li Original Operating Instructions page 20

Wait until the machine has reached its top
speed. You can then position the angle grin-
der on the workpiece and machine it.
6.3 Battery capacity indicator (Fig. 1c/Item 9)
Press the battery capacity indicator switch (a).
The battery capacity indicator (9) shows the char-
ge status of the battery using 3 LEDs.
All 3 LEDs are lit:
The battery is fully charged.
2 or 1 LED(s) are lit:
The battery has an adequate remaining charge.
1 LED fl ashes:
The battery is empty, recharge the battery.
All LEDs blink:
The battery temperature is too low. Remove the
battery from the equipment, keep it at room tem-
perature for one day. If the fault reoccurs, this me-
ans that the rechargeable battery has undergone
exhaustive discharge and is defective. Remove
the battery from the equipment. Never use or
charge a defective battery.
6.4 Changing the grinding wheels (Fig. 5)
Warning!
•
Simple wheel change by spindle lock:
•
Press the spindle lock and allow the grinding
wheel to latch in place.
•
Open the flange nut with the face spanner.
(Fig. 5)
•
Change the grinding or cutting wheel and
tighten the flange nut with the face spanner.
Notice!
Only ever press the spindle lock when the
motor and grinding spindle are at a stand-
still! You must keep the spindle lock pressed
while you change the wheel!
For grinding or cutting wheels up to approx. 3 mm
thick, screw on the fl ange nut with the fl at side
facing the grinding or cutting wheel.

6.6 Motor
It is vital for the motor to be well ventilated during
operation. Be sure, therefore, to keep the ventilati-
on holes clean at all times.
6.7 Grinding Wheels
•
Never use a grinding or cutting wheel bigger
than the specified diameter.
•
Before using a grinding or cutting wheel,
check its rated speed.
•
The maximum speed of the grinding or cut-
ting wheel used must be higher than the idle
speed of the angle grinder.
•
Use only grinding and cutting wheels that are
approved for a minimum speed of 8,500 rpm
and a peripheral speed of 52 m/sec.
•
Check the direction of rotation when you use
diamond cutting wheels. The directional arrow
on the diamond cutting wheel must point in
the direction in which the tool rotates.
Take special care that the grinding/sanding
wheels are properly stored and transported.
Ensure that the grinding/sanding wheels are
never exposed to shock, jolts or sharp edges (for
example during transport or storage in a toolbox).
This could cause damage (such as cracks) to the
grinding/sanding wheels and place the user in
serious danger.
Warning!
6.8 Operating Modes
6.8.1 Rough grinding (Fig. 10)
Caution: Use the safety device for san-
ding/grinding (included in items supplied).
For the best rough grinding results, hold the grin-
ding wheel at an angle of between 30° and 40° to
the workpiece surface and guide back and forth
over the workpiece in steady movements.
6.8.2 Cutting (Fig. 11)
Caution: Use the safety device for abrasi-
ve cutting (available as accessory, see 7.3)
When you use the right-angle grinder for cutting
purposes, avoid tilting it in the cutting plane. The
