Save all warnings and instruc-
tions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Trimmer safety warnings
Hold the power tool by insulated gripping
1.
surfaces only, because the cutter may contact
its own cord. Cutting a "live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
Use clamps or another practical way to secure
2.
and support the workpiece to a stable platform.
Holding the work by your hand or against the body
leaves it unstable and may lead to loss of control.
The trimmer bit shank must match the
3.
designed collet chuck.
Only use a trimmer bit that is rated at least equal
4.
to the maximum speed marked on the tool.
Wear hearing protection during extended
5.
period of operation.
Handle the trimmer bits very carefully.
6.
Check the trimmer bit carefully for cracks or
7.
damage before operation. Replace cracked or
damaged bit immediately.
8. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
9. Hold the tool firmly.
10. Keep hands away from rotating parts.
Make sure the trimmer bit is not contacting the
11.
workpiece before the switch is turned on.
12. Before using the tool on an actual workpiece, let
it run for a while. Watch for vibration or wobbling
that could indicate improperly installed bit.
13. Be careful of the trimmer bit rotating direction
and the feed direction.
14. Do not leave the tool running. Operate the tool
only when hand-held.
15. Always switch off and wait for the trimmer bit
to come to a complete stop before removing
the tool from workpiece.
16. Do not touch the trimmer bit immediately after opera-
tion; it may be extremely hot and could burn your skin.
17. Do not smear the base carelessly with thinner, gaso-
line, oil or the like. They may cause cracks in the base.
18. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
19. Always use the correct dust mask/respirator for
the material and application you are working with.
20. Place the tool on stable area. Otherwise falling
