DESCENDING STAIRS
If the lugs of the left and right Rubber Crawlers do not
contact a stair nose at the same time, CARRY-UP will
descend the stairs a
skew. This is a highly risky situation.
②
Check that Select Switch is set to DRIVE and then
tilt the machine to a shallower angle than the stairs'
angle. Press DOWN. The machine will start de-
scending the stairs.
Pay attention that both Rubber Crawlers run at a
right angle to the stair.
