OPERATION
OF
HYDRAULIC
CUTOFFS
GENERAL
The cutoffs are
one
of the
most
importantfunctions of the
paver. when used properly. Cutoffs are
used
primarily to
control the flow of asphalt to
the
screed. Cutoffs
can
be
used
when
making narrow passes, at Ulilbeginning
and
ending of each pass
or
pull. The cutoffs have been
designed to
break
away if accidently
bitS
a man hole
or
ridge.This feature will prevent excessive damage to
cutoff. (Tack underneath will break.)
1.
Moving
the
hydraulic
handle
forward
will
increase
asphaltflow to the screed. Pulling
the
handlebackwill
decrease asphalt flow.
NOTE
Always

If
handle
is
allowed to return to
center
position
on
its own, it
may
pass

and
cause cutoff to drift openonce
pressure is lost.

spraydown
on

this
material
will
cause
damage
to
components.
Spray
