3) After grease supply is finished on one side, put back the side cover.
Hitting it on the edge of the stainless steel sheet when attaching may cause the sheet damaged or
meandered, which may result in earlier degradation or wear-out of the sheet.
Therefore, to avoid a touch to the sheet edge, insert a shim (approx. 0.1 to 0.2mm) between the
sheet and cover to put the sheet up when pushing in the cover.
When attaching the side covers, tighten the screws with the tightening torque described below.

Caution:

Pay attention not to have the stainless steel sheet bent forcefully or damaged when
working.
Also, there is a risk of getting hurt on the edge of the stainless sheet. Make sure to
have a safety countermeasure such as wearing gloves while working on.

In case the grease got into your eye, immediately go see the doctor to get
appropriate care. After finishing the grease supply work, wash your hands carefully
with water and soap to rinse the grease off.
4) Next, supply grease to the guide on the other side. Remove the attachment screws (at arrows) on
the side cover to detach the side cover on the other side.

For some stroke patterns, there is another attachment screw on the side cover between two
screws on right and left ends.
Make sure to remove them all.
