directly the manufacturer. It is forbidden to work with the trencher being out of
order.
o
It is strictly forbidden to block the machine controls anyhow and
to prevent their return in the neutral position. It is also forbidden
to start working with removed guards or with non-functional
safety elements/switches (dead-man control – any ballast on the
attendant’s ramp).
o
If fuel refilling is required then put the machine out of operation and
let the engine cool down. Be aware of flammable petrol vapours.
o
For filling the tank use always a proper funnel and canisters.
o
If any petrol is spilled or overflowed then wipe off the spots and let
them fully evaporate before the next start.
Putting the Trencher Aside
It is possible to put the trencher aside only on flat and even terrain or up to the
permissible limits as to its climbing ability, i.e. up to 12
o
. Avoid putting it aside on
soft or unstable ground.
The trencher is powered
hydraulically, i.e. by means of a
hydraulic pump. After some operation
hydraulic oil will get hot and the entire
system may show some oil leakage. It
may bring slow unwished motion of
the tracks. That is why you should
insert a corresponding locking pin into
the idle track wheel, see fig. In its
locking position the pin must be
forelocked.
While working, this locking pin is
located on the RH machine side (see fig.) Should the pin be pulled out from its
holder, the engine shall turn off. During operation the pin is placed in a box close
to the fuel tank neck.
When the trencher has been put aside on hilly terrain, this locking
pin may stuck in the idle wheel teeth which makes its next pull-out
more difficult.
