Environmental Requirements - Brother ZM-850A Bedienungsanleitung

2. Notes on safety
Use the sewing machine in an area which is free
from sources of strong electrical noise such as
high-frequency welders.
Sources of strong electrical noise may cause prob-
lems with correct operation.
Any fluctuations in the power supply voltage should
be within ±10% of the rated voltage for the machine.
Voltage fluctuations which are greater than this may
cause problems with correct operation.
The power supply capacity should be greater than the
requirements for the sewing machine's electrical
consumption.
Insufficient power supply capacity may cause prob-
lems with correct operation.
Machine installation should only be carried out by a
qualified technician.
Contact your Brother dealer or a qualified electrician
for any electrical work that may need to be done.
The sewing machine weighs more than 38 kg. The
installation should be carried out by two or more people.
Do not connect the power cord until installation is
complete, otherwise the machine may operate if the
treadle is depressed by mistake, which could result in
injury.
Be sure to connect the ground. If the ground connec-
tion is not secure, you run a high risk of receiving a
serious electric shock, and problems with correct
operation may also occur.
CAUTION

Environmental requirements

Installation
ZM-850A, 851A (English)
The ambient temperature should be within the range
of 5°C to 35°C during use.
Temperatures which are lower or higher than this may
cause problems with correct operation.
The relative humidity should be within the range of 45%
to 85% during use, and no dew formation should occur
in any devices.
Excessively dry or humid environments and dew for-
mation may cause problems with correct operation.
Avoid exposure to direct sunlight during use.
Exposure to direct sunlight may cause problems with
correct operation.
In the event of an electrical storm, turn off the power
and disconnect the power cord from the wall outlet.
Lightning may cause problems with correct operation.
All cords should be secured at least 25 mm away from
any moving parts. Furthermore, do not excessively
bend the cords or secure them too firmly with staples,
otherwise there is the danger that fire or electric shocks
could occur.
Install the belt covers to the machine head and motor.
If using a work table which has casters, the casters
should be secured in such a way so that they cannot
move.
Be sure to wear protective goggles and gloves when
handling the lubricating oil, so that no oil gets into your
eyes or onto your skin, otherwise inflammation can
result.
Furthermore, do not drink the oil under any circum-
stances, as it can cause vomiting and diarrhoea.
Keep the oil out of the reach of children.
