Transport support pin

2.

Spring cotter pin

The harrow has a transport support which prevents the machine lowering down accidentally in case of a
users fault or a sudden leak in the hydraulics. Transport support pin 1 must be set to its hole and locked
with pin 2 before any road transport.

Always before the road transport, make sure that the side wings have locked to the transport position.
Unintended opening of the wings should be prevented by closing the ball valve in the hydraulic hose.
Turn the lever crosswise to the hose. See section 4.4 in this manual.

2.4.

Using the harrow

The operator must be familiar with the operation of the harrow and he/she must have the knowledge
and  skills  to  operate  the  harrow  correctly.    The  operator  must  study  the  operating  instructions  and
follow them.
The condition of the harrow, the tightness of the bolts and the tyre pressures must always be visually
checked  before  starting  work.  Never  adjust  or  clean  a  moving  harrow.  During  work,  persons  are
forbidden  to  ride  the  harrow  or  stand  within  the  working  area  (safety  distance  5  m).  Safety  distance
should  also  be  kept  while  the  harrow  is  not  moving  when  the  hydraulics  is  being  used.  Pressurised
hydraulic cables can release a deadly liquid spray. The side sections of the harrow can only be raised and
lowered  when  the  harrow  is  not  moving.  When  raising  or  lowering  the  side  sections,  ensure  that  no
persons are standing near the harrow. Before transport, ensure that the side sections are set to transport
position and locked. Before commencing working with the harrow, side sections must be fully lowered,
so that the cylinders are fully extended.
The  side  sections  of  the  harrow  should  be  raised  and  lowered  by  keeping  the  hydraulic  pressure
continuously on during the whole movement. Interrupting the movement may disturb the function of a
valve in the system and the side sections will not move at the same time. Sudden change to the balance
may cause the harrow to tip over. This applies in particular 800 – 1500 harrows.
