8. TO USE THE GRINDER (SEE FIG. I)
Attention: Do not switch the grinder on while the disc is
in contact with the workpiece. Allow the disc to reach full
speed before starting grinding.
Hold your angle grinder with one hand on the main handle and
other hand firmly around the auxiliary handle.
Always position the guard so that as much of the exposed disc
as possible is pointing away from you.
Be prepared for a stream of sparks when the disc touches the
metal.
For best tool control, material removal and minimum
overloading, keep an angle between the disc and the workpiece
surface at approximately 15
0
to 30
0
when grinding. Use
cautiously when working into corners as contacting with the
intersecting surface may cause the grinder to jump or twist.
When grinding is complete, allow the workpiece to cool. Do
not touch the hot surface.
9. OVERLOAD
Overloading will cause damage to the motor of your angle
grinder. This can happen if your angle grinder is subjected to
heavy use for prolonged periods of time.
Never attempt to exert too much pressure on your angle
grinder to speed up your work.
The abrasive discs operate more efficiently when light
pressure is exerted, thus avoiding a drop in the speed of your
angle grinder.
If your angle grinder becomes too hot, run it no load for 2-3
minutes until it has cooled to normal operation temperature.
10. DISPOSAL OF AN EXHAUSTED BATTERY PACK
To preserve natural resources, please recycle or dispose of
the battery pack properly. This battery pack contains Lithium
batteries. Consult your local waste authority for information
regarding available recycling and/or disposal options.
Discharge your battery pack by operating your drill, then
remove the battery pack from the drill housing and cover the
battery pack connections with heavy duty adhesive tape to
prevent short circuit and energy discharge. Do not attempt to
open or remove any of the components.
WORKING HINTS FOR YOUR ANGLE
GRINDER
1. Always start at no load to achieve maximum speed then
start working.
2. Do not force the disc to work faster, reducing the disc’s
moving speed means longer working time.
3. Always work with a 15° to 30° angle between disc and
workpiece. Larger angles will cut ridges into the workpiece
