MECHANICAL EDGE-O-DOCK ADJUSTING INSTRUCTIONS
1.)
Stand on the ground in front of the leveler. Raise the leveler to
to its vertical position. Place fork truck forks under lip to hold lip
out at nearly level position. Never work directly under fork truck forks.
2.)
To adjust the counterbalancing force use the pipe lever
supplied with the dockleveler and a 3/4" open
end wrench or socket. Place the open end of the pipe
over the protrusion on the casting and rotate
down. We recommend one person to rotate the spring
with the pipe handle to the desired strength and
a second person to tighten the 3/4" bolts onto the milled flats.
3.)
When the required lifting torsion is reached, return to
leveler to normal operating position. Check the
adjustments made, and, if not lifting properly, repeat the
previous steps to either increase or decrease spring
lifting torsion. If the leveler is bouncing or floating when
the lip is extended, there is too much lifting torsion.
Repeat the previous steps in reverse to reduce lifting torsion.
NOTE:
This is an excellent time to lubricate the grease zerks on the hinges. A standard grease gun will service
these. This must be done regularly for ease of operation and maintenance, as we recommend monthly.
