INSTALLATION
NOTICE: Use an approved, high-grade pipe sealant to seal all
hydraulic connections.
1. Remove the dust cover and rubber plug from coupler.
2. Inspect all threads and fittings for signs of wear or damage, and
replace as needed. Clean all threads and fittings.
3. Connect hydraulic hose from hydraulic pump to the cylinder
coupler. Ensure that there are no fluid leaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualified
personnel.
NOTICE: The use of cylinder attachments or extensions reduces
the cylinder capacity by at least 50% per attachment/extension.
WARNING: Before operating the pump, tighten all
hose connections with proper tools. Do not overtighten.
Connections should only be tightened securely and leak-free.
Overtightening can cause premature thread failure or high
pressure fittings to burst.
WARNING: Before repairs are made, depressurize cylinder.
Tips for hydraulic hoses & fluid transmission lines:
• Avoid short runs of straight line tubing. Straight line runs do not
provide for expansion and contraction due to pressure and/or
temperature changes.
• Reduce stress in tube lines. Long tubing runs should be
supported by brackets or clips.

before it is properly supported. Never rely on hydraulic
pressure to support a load. Immediately after lifting, thread
the lock-nut into locking position.
