CUTTING AROUND OUTLET BOXES IN
DRYWALL
Fig.K - Q
Do not use this tool to make cutouts around any fix-
ture or opening that has live electrical wires, or any
wall that may have live electrical wiring behind it. The bit could
conduct current to the tool, creating an electrocution hazard
for the operator.
If cutting into existing walls or other blind areas is unavoidable,
disconnect all fuses or circuit breakers to the worksite. Always
hold the tool by its thermoplastic housing.
To cut around an outlet box in drywall
• Push the electrical wires back or to the far side of the
box so that the bit does not cut the wires when inser-
ted through the drywall.
• Make a mark somewhat near the centre of the ope-
ning in the box on the side of the drywall facing you
before fastening the drywall.
• Fasten the drywall with nails or screws. Do not nail or
fasten screws closer then 12" from the box, or the
drywall may bulge or blister from the excess pres-
sure.
• Switch the tool "ON".
• Push the bit through the mark you made while hol-
ding the tool firmly with both hands. See Fig.K.
• Guide the bit to the right until you feel and hear the
bit touch the inside edge of the box. See Fig.L.
• Pull out the bit far enough to slip it over the edge of
the box so it is now against the outside of the box.
• Move the bit in counterclockwise direction until you
feel and hear it come to the upper left corner. To do
this, apply light upward pressure and keep the bit in
contact with the outside of the box. See Fig.M.
• Round the upper right corner applying light down-
ward and inward pressure.
• Move the bit along the top contour until you feel and
hear it come to the upper left corner. To do this,
apply light pressure to the right and keep the bit in
contact with the outside of the box. See Fig.N.
• Round the upper left corner applying light downward
and inward pressure.
• Move the bit along the left side contour until you feel
and hear it come to the lower left corner. To do this,
apply light downward pressure and keep the bit in
contact with the outside of the box. See Fig.O.
• Round the lower left corner applying light upward
and inward pressure.
• Move the bit along the bottom contour until you
feel and hear it come to the lower right corner. To do
this, apply light pressure to the right and keep the bit
in contact with the outside of the box. See Fig.P.
• Round the lower right corner applying light upward
and inward pressure.
• Move the bit along the right side contour until
you meet the initial upward cut. To do this, apply light
upward pressure and keep the bit in contact with the
outside of the box.
• Switch the tool "OFF". See Fig.Q.
• Take the bit out of the box.
MAINTENANCE
Make sure that the machine is not live when car-
rying out maintenance work on the motor.
The Ferm machines have been designed to operate over
a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon pro-
per machine care and regular cleaning.
Cleaning
Keep the ventilation slots of the machine clean to pre-
vent overheating of the motor.
Regularly clean the machine housing with a soft cloth,
preferably after each use. Keep the ventilation slots free
from dust and dirt.
If the dirt does not come off use a soft cloth moistened
with soapy water. Never use solvents such as petrol,
alcohol, ammonia water, etc. These solvents may
damage the plastic parts.
Lubrication
The machine requires no additional lubrication.
Faults
Should a fault occur, e.g. after wear of a part, please con-
tact your local Ferm dealer.
In the back of this manual you find an exploded view
showing the parts that can be ordered.
ENVIRONMENT
In order to prevent the machine from damage during
transport, it is delivered in a sturdy packaging. Most of
the packaging materials can be recycled. Take these
materials to the appropriate recycling locations.
Take your unwanted machines to your local Ferm-
dealer. Here they will be disposed of in an environmen-
tally safe way.
