Step 3:
Installation of the pre-assembled main frame unit (1) on the
left and right supports (24+33).
1. Lay the screws M8x50 (63), two washers 8//22 (64) accessibly
beside the bottom frame (23).
2. Place the main frame unit (1) between the supports (24+33) and
align so that the hole patterns in the main frame (1) and the
supports (24+33) are aligned. (Note: You should ask a second
person to hold the main frame unit (1) or support it with a sui-
table object to perform the following steps of assembly.)
3. Place a washer (64) on each screw (63) and then push the
screws through the holes in the supports (24+33) and tighten
the main frame (1) firmly.
4. Put the ends of the sensor cable (42) (projecting from the main
frame (1) and sensor connection cable 1 (34) (from the right
support (33)) together.
Step 4:
Installation if the extension tubes (34+53) at bottom frame (23)
and main frame (1).
1. Put the extension tube (34) with bottom part into appropriate
holder of Bottom frame (23) and screw it tightly by using screw
M8x50 (63), washer 8//16 (59) and self-locking nut M8 (19).
2. Fold up the main frame (1) vertically and insert the extension
tube 2 (53) with top side into the appropriate holder at main
frame (1). Screw it tightly by using screw M8x40 (66), washer
(59) and self-locking nut (19).
(Note: The connection points shouldn't tighten too much, so
that the extension tubes (34+53) can move easily during fold up
and down the main frame (1).)
