1. After setting up the machine , remove adjusting cover screw e. and pour oil in up to the reference line on oil gauge e.
2. Turn the pulley until oil ca p e is up , remove oil cap e and pour oil into oil tank 0 until it is full. If th'e o il in the oil tank
decreases below tank center line e.the oil will not be drawn into the upper shaft, causing imperfect lubrication. Be sure to
keep the oil in the oil tank above oil tank center line e.
3. Pour about 5 drops of oil into 3 oil cups e and needle bar bushing oil hole e every week .
4.
Remove oil drain screw e from time to discharge the used oil which has collected in the front bed oil sump .
5. Wipe arm jaw e and rear bed oil sump e from time to time· to remove oil from them.
