Check with a spirit level (Pic. 9) that each
foot-tube or the frame above does not lean in
either the boat's longitudinal or transverse
direction.
If the lift is tilted in the boat's cross-direction
can be compensated by raising one hand a
few centimeters by turning its handle a
number of rev. before the lifting begins.
Another board can also be placed under foot.
If the lift is tilted in the boats along direction
this can be compensated by standing on the
footboard (Pic.10) and push each frame pole
against the inclination until it is vertical. A
long-hole in the base brackets allows tilt
adjustable. The bolt that goes through the
long hole has to be tightened so that the frame
remains in its position after adjustment.
Pretension lifting strap by loosening the blue
knobs (Pic. 4) slightly and bring its fittings
downwards.
Tighten the blue knobs by hand.
Check that the belt is aligned between the lift
poles so that not lift starts to tilt forward or
backward when lifting.
Two people twist their individual handles a
decided number turns at the same time.
Decide such that now we turn 10 half-turns =
30 mm. One full turn raises 6mm. Easier to
count the half-turns.
When the lifting belt become tight so control
that the posts do not lean to one side and
everything feels stable. Repeat the check
frequently, every 30 mm raised.
Maximum lift height is 400 mm and then it
becomes a red color visible above the handle
nut after which the lifting movement must
end immediately.
Gently roll in the trailer under the boat as
much as possible by hand and then immerse
the boat to the trailer rolls careful.
