Refer to the table below for maximum and standard

speeds of the Series. To extend machine life, run

the machine approximately 15~20% below the

maximum speed for the first 200 hours of operation

(approx. 1 month). Then run the machine at the

standard speed. The machine pulley turns

counterclockwise as seen from the end of the

machine pulley.

diameter on the table below). Adjust where to

position the motor by pressing the finger onto the

middle of the belt so that 1~2cm deflection can be

obtained (see the illustration on the right).

Fill the machine with oil until the oil level is at the

top line (see H in the illustration) on oil gauge C.

After the first lubrication, add oil so that the oil

level will be between H and L.

To check for proper oil flow

After filling the machine with oil, run the machine

to check the oil is splashing from oil pipe outlet B.

To extend machine life, be sure to replace the oil

after the first 250 hours of operation.

To replace the oil, follow the procedures below.

1. Remove the V belt from the motor pulley and

then remove the machine from the table.

2. Remove screw D and then drain the oil.

Be careful not to stain V belt with the oil.

3. After draining the oil, be sure to tighten screw

4. Fill the machine with oil by referring to 3-2

shown above.

If filter element E is contaminated, proper oiling may not be performed.

Clean the filter element every six months. If just a little or no oil flows out from the

nozzle with the proper amount of oil in the machine, check the filter element.

To clean the filter element, remove oil reservoir.

To obtain the proper angle and height, insert the

looper fully into looper holder A and then tighten

screw B.

The proper angle for the looper on V7100 and W8100

is 3°. Distance at 25mm from the point of the looper

between the bottom of the looper blade and the

extension line from the point of the looper :

Approximately 1.3mm

When the point of the looper, moving to the left or

right, has reached the left side of the left needle,

distances As from the top of the left needle's eye to the

point of the looper should be the same.(see the

illustration on the right). To adjust the timing of the

looper to the needles, remove the machine cover, loosen

three screws C on eccentric B and then shift the

eccentric by turning the machine pulley while holding

the eccentric.
