back forces, if proper precautions are taken.
f
Use special care when working corners, sharp
edges, etc. Avoid bouncing and snagging the ac -
cessory. Corners, sharp edges or bouncing have a
tendency to snag the rotating accessory and cause
loss of control or kickback.
f
Do not use a toothed saw blade. Such blades cre-
ate frequent kickback and loss of control over the
power tool.
f
Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direction
as the chips are thrown). Feeding the tool in the
wrong direction causes the cutting edge of the bit
to climb out of the work and pull the tool in the di -
rection of this feed.
f
When using rotary files, high-speed cutters or
tungsten carbide cutters, always have the work
securely clamped. These wheels will grab if they
become slightly canted in the groove, and can kick -
back. When the rotary file, high-speed cutter or
tungsten carbide cutter grab, it may jump from the
groove and you could lose control of the tool.
SAFETY WARNINGS SPECIFIC FOR GRINDING OP-
ERATIONS
f
Use only wheel types that are recommended
for your power tool and only for recommended
applications. For example: do not grind with the
side of a cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
f
For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved
shoulder flange that are of correct size and
length. Proper mandrels will reduce the possibility
of breakage.
CONNECTION TO THE POWER SUPPLY
Make sure the power supply information on the
machine’s rating plate are compatible with the
power supply you intend to connect it to.
This appliance is Class II and is designed for con-
nection to a power supply matching that detailed
on the rating label and compatible with the plug
fitted. If an extension lead is required, use an ap -
proved and compatible lead rated for this appli-
ance. Follow all the instruction supplied with the
extension lead.
GUIDELINES FOR USING EXTENSION CORDS
f
Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating.
f
Always replace a damaged extension cord or have it
repaired by a qualified person before using it.
f
Protect your extension cords from sharp objects,
excessive heat and damp/wet areas.
f
Use a separate electrical circuit for your tools. This
circuit should be protected with the appropriate
time-delayed fuse. Before connecting the motor to
the power line, make sure the switch is in the OFF
position and the electric voltage is rated the same
as the voltage stamped on the motor nameplate.
Running at a lower voltage will damage the motor.
