SINGER WREX 101 - Manual (Page 5)

MOUNTING MACHINE
I ^ Fasten machine to table using felt pad. Tighten screws
evenly, turning each a little at a time.
When an individual motor and clutch unit is employed,
it is recommended that the motor be rated at 13 HP and
1725 1750 RPM. On all standard models, use a 3’/2"
outside diameter pulley. On models intended for altera­
tion, use a 2’/ 2 " outside diameter pulley.
When the machine is mounted on a power table, a 4"
pulley should be used. If possible, when using such
stands, the machine should be mounted TO AVOID
CROSSING THE BELT.
The maximum machine speed recommended for any
installation is 3000 RPM, unless otherwise specified.
2 The handwheel's direction of rotation is away from the
operator. It rotates in a clock-wise direction when looking at
the face of the wheel pulley, as shown by the arrow.
Either V-belting or round leather belting may be used. Ex­
cessive tension of belt will cause over-heating and freezing
of bearing at handwheel.
