Arm 2 Cover - Toshiba THP550-IP Instruction Manual

• Do not forget to install the gasket.
Also, be sure to coat the Loctite adhesives to all set bolts. Otherwise, the
dust- and drip-proof performance is damaged to cause entry of water or
dust.
• Be sure to replace the gasket before it is damaged. Damaged gasket
causes the deterioration of the dust- and drip-proof performance.

Arm 2 Cover

1) Before the arm-2 cover can be removed, the upper bellows must be removed.
For the procedure to remove the upper bellows, see Para. 5.2.2.
The arm-2 cover is secured together with the packing to the cover bracket by
tightening 12 hexagon socket head cap screws (M4 × 8).
2) Though the cover is embedded to the arm 2, the liquid gasket is applied to the full
circumference of the packing under the cover to maintain the dust- and drip-proof
feature. When disconnecting the cover, peel off the liquid gasket between the
arm 2 and gasket, using a full circumferential cutter, etc. Then carefully peel off
the liquid gasket to remove the cover, using a slotted screwdriver, etc. DO NOT
peel off the liquid gasket between the cover and gasket. Disconnect the cover
together with the gasket. The figure shows the THP550.
