Unfolding/Folding)
Unlocking position (pic. 1)
OPENING
a) In order to open the equipment act slowly on the hydraulic
distributor lever, hooks "B" will lift automatically, proceed
without any jolts until both the two halves of the harrow are
in horizontal position.
CLOSING
a) Check if the harrow is in the position "FIXED or FLOATING
DOWN", in this case you must take away the two pins A and
replace in hole B or C (see paragraph 5.7)
At this point act on the hydraulic distributor lever which closes
the equipment and proceed to the complete closing
manoeuvring until the two moving parts of the harrow get to a
stop in vertical position. Release the lever of the hydraulic
distributor to lower the safety hook "B".
Once folded, put brackets "A" in locking position (pic. 2)
The hydraulic pipes
must be kept far from
any moving component.
Every time you use the
machine, check the
pipes and the fixing
devices of the pipe
fittings for their
conditions. The repairs
must be carried on only
by qualified personnel
using only ALPEGO
original spare parts.
During the closing phase, make sure that the power take-off (PTO) is free of any type of braking.
