10.5. Removing and mounting the up/down shaft bolt
*1. To remove the up/down shaft bolt, the box driver (Ø13 mm) must be used. To install, the torque wrench with Ø13 mm must be
used.
*2. The torque wrench with Ø13 mm socket and the box driver (Ø13 mm) are available as parts.
10.5.1. Removing
The pinion A and pinion B of massager block (left, right) are secured with the up/down shaft bolts.
Remove them with the box driver (Ø13 mm).
(It is possible to use the Phillips head screwdriver. But it may deform the screw head. Therefore, it is necessary to use the box
driver.)
10.5.2. Mounting
!It is necessary to control the tightening torque of the up/down shaft bolt.Up/down bolt tightening torque: 4 N/m (40 kgf-cm).
*If the up/down shaft bolt has been insufficiently tightened, it may loosen when the massager moves up and down, and the
massager may detach from the chair.
If the up/down shaft bolt has been excessively tightened, the bolt head may shear.
Tighten the up/down shaft bolt of pinion A and pinion B, while controlling the torque.
10.5.3.
*Assembly instruction of an ellipse gear
1. .Put the grease(WEP001W8927) on the intermediate gear shaft and insert it in the center hole of the intermediate gear block.
And attach the Plate type spring through the intermediate gear shaft as shown in figure.
2. Match the "V" shape of two ellipse gear on the intermediate gear block and drive pipe.
3. Assemble this block into the Gear box A as they have matched. And insert the intermediate gear shaft of intermediate gear
block into the groove A of Gear box A.
**When aligning two ellipse gears, smooth rotation will not be possible even if the alignment is off by just one tooth. During rotation,
the gears will not match up, and may cause the massager to lock. Correct alignment of two gears required.
