SAFETY INFORMATION

c)

Avoid accidental starting. Ensure the
switch is in the off position before
plugging in.

Carrying power tools with your

finger on the switch or plugging in power
tools that have the switch on invites
accidents.

d)

Remove any adjusting key or wrench
before turning the power tool on.

A wrench or a key left attached to a rotating
part of the power tool may result in personal
injury.

e)

Do not overreach. Keep proper footing
and balance at all times.

This enables

better control of the power tool in
unexpected situations.

f)

Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts.

Loose

clothes, jewellery or long hair can be caught
in moving parts.

g)

If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used.

Use of these devices can reduce dust

related hazards.

4) Power Tool Use And Care

a)

Do not force the power tool. Use the
correct power tool for your application.

The correct power tool will do the job better
and safer at the rate for which it was
designed.

b)

Do not use the power tool if the switch
does not turn it on and off.

Any power tool

that cannot be controlled with the switch is
dangerous and must be repaired.

c)

Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing power
tools.

Such preventive safety measures

reduce the risk of starting the power tool
accidentally.

d)

Store idle power tools out of the reach of
children and do not allow persons
unfamiliar with the power tool or these
instructions to operate the power tool.

Power tools are dangerous in the hands of
untrained users.

e)

Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tools operation.
If damaged, have the power tool repaired
before use.

Many accidents are caused by

poorly maintained power tools.

f)

Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.

g)

Use the power tool, accessories and tool
bits etc., in accordance with these
instructions and in the manner intended
for the particular type of power tool,
taking into account the working
conditions and the work to be performed.

Use of the power tool for operations different
from intended could result in a hazardous
situation.

5) Service

a)

Have your power tool serviced by a
qualified repair person using only identical
replacement parts.

This will ensure that the

safety of the power tool is maintained.

Additional Precautionary Measures
Important:

The machine generates both

airborne and line interference due to the high
frequencies involved. It is important not to
locate electronic or electrically sensitive
equipment in the vicinity of the welder or
alternatively, do not locate the welder in vicinity
of electronic or electrically sensitive equipment.
