4 INSTALLATION AND START-UP
4.1 Securing the 4-way valve
The 4-way valve must be installed on a stable foundation, which must be level and stable, so that the
4-way valve is not twisted or exposed to a ±0.1 mm profile distortion.
Bolts must be tightened in accordance with supplier’s instructions.
Ensure that the flow direction is correct before assembly.
The 4-way valve’s end stop can only be used as a stop when operating with manual handle bar. When
activated with a cylinder, the cylinder’s own end stop is used.
4.2 Adjusting the 4-way valve
The cone in the 4-way valve can be adjusted by turning the set screw (Pos.2):
• Clockwise to lift the cone.
• Counter clockwise to lower the cone.
It is important to lock the screw after adjustment by tighten the nut (Pos.1) clockwise.
If the 4-way valve is blocked, it is possible to adjust the cone.

A failure to observe the inspection intervals described in table below, may result in
damage to the 4-way valve.
5 INSPECTION INTERVALS
Section Operation Interval Category 1 Category 2
5.1 Visually inspect for leakage Weekly X X
5.2 Inspection and cleaning (if necessary) Monthly X X
5.3 Inspection and lubrication 3 months X X
5.1 Inspecting for leakage
The 4-way valve and pipe system around must be inspected for leakage once a week. The inspection must
be performed when the 4-way valve is both operating and idle. Any leaks must be repaired before operation
may continue.
The pipe connections of 4-way valves must be inspected at least once a month, and any contaminants
must be removed.
The 4-way valve must always run easily and effortlessly, otherwise it must be cleaned.
5.2 Inspection and cleaning
Only qualified personnel may carry out repairs.
Repairs must be carried out according to manufacturer recommendations.
Use only original materials and components as described, during repair and maintenance.
During repair or disassembly, check that the flow direction remains unchanged.
For repair of the actuator, see accompanying supplier instructions.
Bolts must be re-tightened in accordance with supplier’s instructions.
Each grease nipple must be greased every 3 months, with 6-8 g of LGWA2 grease.
If 4-way valve not in use for 1 month or more, it must be greased before start.
