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ttingsforsignsofwearordamage,and
replaceasneeded.Cleanallthreadsandttings.
3. Connecthydraulichose from hydraulic pump to the cylinder
coupler.Ensurethattherearenouid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 ttings to burst.
WARNING: Before repairs are made, depressurize cylinder.
