To Lubricate the Motor
USE ONLY SINGER MOTOR LUBRICANT
FOR LUBRICATING THE MOTOR.
A tube
of this lubricant is sent with the machine.
The Singer Motor Lubricant is a specially
prepared non-flowing compound which is not
affected by varying temperatures. It is the
only lubricant which will positively lubricate
the motor. Other lubricants, including oil,
vaseline or ordinary grease must not be used
for lubricating the motor, as they are harmful
for this purpose.
When the machine is shipped from the factory,
the two motor grease cups (A, Fig. 26) are filled
with sufficient Singer Motor Lubricant for approxi
mately one year’s use, under ordinary circumstances.
At least once a year thereafter, turn the machine
back on its hinges and remove the two thumb
screws from the two grease cups (A) and clean out
the interior of the cups. Then insert the tip of the
motor lubricant tube into the grease cups as shown
in Fig. 26, and, while holding the tube firmly against
the bottom of the grease cups,
squeeze about a
quarter of a tube of the lubricant into each
cup,
then replace and tighten the thumb screws.
