The top of the table should be 50 mm in thickness and should be strong enough to hold the weight and withstand the
vibration of the sewing machine. Drill holes in the table as shown in the diagram below.
3. INSTALLATION
CAUTION
Machine installation should only be carried out
by a qualified technician.
All cords should be secured at least 25 mm away
from any moving parts.
Furthermore, do not excessively bend the cable
or secure it too firmly staples, otherwise there is
the danger that fire or electric shocks could occur.
The sewing machine head weighs more than 87
kg. The installation should be carried out by two
or more people.
Do not connect the power cord until installa-tion
is complete, otherwise the machine may
operate if the start switch is pressed by mistake,
which could result in injury.
Be sure to connect the ground. If the ground
connection is not secure, you run a high risk of
receiving a serious electric shock, and problems
with correct operation may also occur.
Contact your Brother dealer or a qualified
electrician for any electrical work that may need
to be done.
Install the belt covers to the machine head and
motor.
