Remedy

neutral
To determine whether cylinder is
leaking, cap lines coming off the
cylinder. If the cylinder still creeps,
contact Weldco-Beales Mfg. for
further information.
If the float on the snow wing is not
operating properly, check the control
valve to determine if the installation
has been done correctly. O-rings
should be checked for damage
incurred during installation.
If the snow wing moldboard goes
over centre in the raised or transport
position, and the cylinder is not
capable of retracting the moldboard,
one should seek assistance in
returning the moldboard to its proper
stowed position. Do this in a clear,
open area and in a safe manner.
Check to determine if the pushpole
stops have been correctly installed.
Adjust if necessary.
See Scorpion instructions for details.
