LUBRICATION
CAUTION!
Oil has been drained from the main reservoir before shipment and the reservoir must be filled
before starting to operate.
Lubricate machine thoroughly, in accordance with instructions which follow, and run slowly for several
minutes to distribute the oil to the various parts. Full speed operation can then be expected without
d a m a g e .
RECOMMENDED OIL
Use a stainless water-white straight mineral oil of a Saybolt viscosity of 90 to 125 seconds at 100° Fahrenheit
in the main reservoir. This is equivalent to Union special specification No. 175. Fill main reservoir at plug
screw (B, Fig. 3) and check oil level at gauge (C): oil is at maximum level when needle is in yellow band
marked "FULL". Oil should be added when needle is in yellow band marked "LOW".
It is recommended that a new machine, or one that has been out of service for an extended period, be
lubricated as follows: Remove the head cover and directly oil the bearings of the needle bar link, the take-
up and its lever and needle bar. Replace end cover, as no further hand oiling will be required.
Oil may be drained from main reservoir by removing plug screw (D, Fig. 3).
OIL GAUGE
The oil gauge is set at the factory to show the proper oil level in the reservoir. Should and adjustment
become necessary, the following steps should be followed:
1.
Place the machine upright on a level table or bench.
2.
R e m o v e t h e r e s e r v o i r p l u g s c r e w ( l o c a t e d b e l o w t h e h a n d w h e e l a n d n e a r t h e b o t t o m o f t h e
m a c h i n e ) .
3.
Oil should be added or removed so that the oil level is approximately 1/8 inch below the bottom edge
of the hole.
4.
Loosen lock nut (E, Fig. 3) on the calibrating screw (F), and turn screw left or right so the gauge needle
rests on the yellow band marked "FULL" on gauge (C).
5.
Tighten lock nut and replace plug screw.
