1 Check the cylinder anchor nuts for properly installed
locking caps and cotter pins.
2 Check for external leaks at the fittings and rod ends.
25D, 35D, 40D and 50D Clamps – The clamp utilizes a
regenerative hydraulic circuit in the arm opening mode.
The arms will open at a faster speed than when closing.
This is normal. If required, the regenerative function
can be eliminated. Refer to Section 5.6-5.
3 Check for equal arm travel. If arm travel is unequal, the
restrictor cartridges should be adjusted as follows:
A Loosen the jam nuts on the restrictor cartridges.
Screw in the plungers until they bottom. Screw each
plunger out three full turns.
B Activate the arms to the fully open position
C Activate the arms to close until one arm bottoms
out. Measure the amount of stroke remaining in the
opposite arm.
D If unequal closing movement exceeds 2 in. (50 mm),
screw the plunger in 1/2 turn on the cylinder that
bottoms first.
E Repeat step A through D until unequal closing
movement is less than 2 in. (50 mm).
4 Before picking up a load, cycle the clamp function
through several full cycles. Check for operation in
accordance with ITA (ISO) standards.
WARNING: Make sure all personnel are
clear of the clamp during testing.
