4.2 Changing Clamping Bolt
1. To replace clamping bolt, loosen jam nut and unscrew bolt
from clamping arm.
2. Replace with new bolt or toggle pad having 1/2-13 UNC 2A
threads.
3. Tighten jam nut.
4.3 Mounting the Swing Cylinder
Mount cylinder to fixture using two bolts. Attach hydraulic supply
line to hydraulic pressure port.
NOTE: Avoid contaminants in your hydraulic system. Tubing
should be flushed prior to assembly. Solvent may be used as long
as each piece is dry prior to assembly. After system has been
assembled, flush with hydraulic oil – not solvent. Solvents can and
will cause premature seal failure.
5.0 OPERATION
Trapped air will result in erratic swing clamp operation. Remove
air from system for smooth operation.
1. Apply low hydraulic pressure to system (approximately 5 to
10 psi).
2. Loosen the attachment fitting at pressure port.
3. Tighten fitting after air is expelled and only hydraulic fluid is
expelled from fitting.
4. Swing clamp can new be operated up to full rated pressure
of 2,500 psi.
Never exceed 2,500 psi hydraulic pressure or rated
load capacity. Exceeding the rated limits of your
swing clamp will result in personal injury and/or
equipment damage.
6.0 MAINTENANCE
Perform maintenance regularly to keep swing clamps in good
operating condition.
1. Keep all moving parts free of debris and coolant. Coolant
may damage seals.
2. Keep system full of Enerpac hydraulic oil. Be sure cylinders
are fully retracted when adding oil to system. Use of other
fluids in not recommended. Other fluids may damage seals
and void the warranty.
3. Check that fittings and mountings are tight. Loose fittings
permit dirt to enter your system as well as allowing oil to leak
out. Loose mountings can cause damage to parts or fixtures.
4. Check for oil leaking from swing clamp. Leaks are usually
caused by damaged or worn seals. Seals are available in the
Repair Parts Kit for your swing clamp.
5. Refer to Repair Parts Sheet L1679 to order parts and perform
service work.
