For complete operating instructions refer to the instruction sheet included with each pump.
5.1
Advancing and retracting the cylinder
The RFJ Series cylinders are a spring return cylinder and the speed of retraction is
affected by the length of the hose and other restrictions in the line.
Shift the valve on the pump to the advance position and run the pump to advance the
cylinder. To retract the cylinder, shift the valve to the retract position.
5.2
Side Load
Eliminate the presence of side load forces when using high tonnage cylinders. Side load
can occur through:
5.2.1
An eccentric load on the piston rod.
5.2.2
A horizontal load on a structure.
5.2.3
A structure and/or cylinder misalignment.
5.2.4
Non synchronised lifting actions.
5.2.5
Non stable cylinder base support.
5.2.6
If using cylinder stack plate kits, do not exceed the number of plates in the
supplied kit, ie. do not combine kits to gain extra height.

Maintenance
IMPORTANT:
Use only good quality hydraulic fluid.
Do NOT
use brake fluid, transmission fluid,
turbine oil, motor oil, alcohol, glycerine etc. Use of anything other than good quality
hydraulic oil will void warranty and damage the cylinder and application. We
recommend Durapac Hydraulic Oil or equivalent
Equipment must only be serviced by a qualified hydraulic technician. For repair service,
contact your local Durapac authorised service centre
Tighten connections as needed. Use non-hardening pipe thread compound when
servicing connections
Dirt, sand, etc. will quickly ruin any hydraulic system. Ensure that couplings are clean and
free of foreign matter. After each use, clean couplings and attach dust caps.
Maintenance is required when wear or leakage is noticed. Periodically inspect all
components to detect any problem that may require service and maintenance.
6.1
Check for loose connections and leaks.
6.2
Replace damaged parts immediately.
6.3
Do not exceed oil temperature above 60
o
C.
6.4
Keep all hydraulic components clean.
