707.5 and 707.10, wood splitter cylinder and
double acting cylinder crutch
– Zinc plating on micro cylinders

Recommendations

– Protection of the circuit by a relief valve and a filter
– Check the oil cleanness (pollution)
– To bleed the air from the cylinder and the
hydraulic circuit

The cylinder should not, under any circumstances,
be used as a mechanical limit stop for
moving loads.
For double-acting cylinders working as singleacting,
it is essential to connect the unused port
to the tank or safe environment

• Welding: do not weld on the tube. Dismount
the cylinder to weld on the rod or on the base

• Storing: storage of extended cylinder, the rod
must be greased. For high pressure cleaning,
protect the rod.

• Dismantling the cylinder : Warning : we use
loctite engineering adhesive and a special locking
ring to fasten the piston to the rod. Once
the piston has been removed it will require
a new locking ring and re-application of the
appropriate loctite.
