Remove the Bleed Screw
Using a 6-mm Allen wrench, you must remove the
light-colored plastic cap that covers the clutch
adjustment screw on the 820 or 860 Slide Gate Operator
for two reasons (see Figure 17):
•
You will break the plastic cap if you attempt to
turn it, thinking it is the clutch adjustment
screw.
•
The plastic cap functions as a breather screw
cap and must be removed during operation to
allow the operator to "breathe."
You should save the plastic cap in case you ever
transport the operator. Transporting the operator
without the plastic cap installed allows oil to leak out if
the operator is tipped over during transport.
