Hydraulic Speed Control Kit Operation
Turning the SLOW SPEED knob rotates the rod.
This in turn causes the contact block to ride up or down
on the rod, moving the contact point closer to or further
from the hydraulic cylinder at rest.
This distance determines how far the contact block, and
therefore the slide assembly, must travel before the block
contacts the plunger of the hydraulic cylinder.
The plunger has a maximum travelling distance of one inch
(25.4 mm). The first 1/4 inch (6.4 mm) of travel decelerates
the speed of the slide assembly. The remaining 3/4 inch
(19.1 mm) of travel allows the slide assembly to descend
at a constant slow speed set by the operator.
The slide assembly can only travel downward a maximum
of one inch (25.4 mm) after the block contacts the plunger.
Hydraulic Speed Control
Adjustment
Rotating this shaft adjusts the internal metering aperture
which regulates the flow of the silicone fluid. There are
two ways to adjust the hydraulic speed control setting. First
make sure that the slide assembly is fully retracted (up po-
sition). This will uncover the hydraulic damper and shaft.
• Insert the end of a small screwdriver or similar tool
into the hole (Figure 6-5) in the adjustment shaft of
the hydraulic cylinder, OR,
• Locate the slot on the bottom of the cylinder (Figure
6-6). Insert a screwdriver in the slot and adjust the
setting.
Just above the shaft is a scale with 30 divisions. On
the adjustment shaft is a vertical groove that indi-
cates where along the scale the speed is set. Zero (0)
is the fastest setting, and thirty (30) is the slowest setting.
