Model SF:
If the lugs of the left and right Rubber Crawlers do not
contact a stair nose at the same time, CARRY-UP will
climb the stairs a
skew. This is a highly risky situation.
(2)
Proper weight balance:
Lay the machine on the stairs with Main Wheels a
little aloft.
If the machine does not turn to the handle side or
Main Wheels side, the center of gravity is within
the proper range.
③
Tilt slowly until Rubber Crawler contact the sec-
ond stair.

angle.
