VI-5 REMOVAL - INSTALLATION PROCEDURES
5- Lubricate the rod with new hydraulic oil.
6- Remove the cover from the cylinder barrel.
Ensure the barrel is clean.
7- Lubricate the wear ring with new hydraulic oil
and install the rod assembly in the cylinder
barrel with a slight twisting motion.
Do not use compressed air to test or pressurize
the cylinder.
8. Lubricate and test the cylinder. Check for proper
operation and any leakage.
Installation
1- Ensure the cylinder support plate is properly
installed (see fig. 6.2, § 6.3.1).
2- Install the cylinder, its plate and pin on the
cylinder brackets turning the cylinder barrel if
necessary. Lock in place with a new retaining
ring. Ensure the bleeder screw is opposite the
access hole on the 2nd mast section (see fig.
4.5, § 4.8).
3- Install both bolts and lock washers.
4- Remove the cap from the hydraulic hose and
connect the hose.
5- Connect the connector.
6- Install and secure the base on the mast
assembly as indicated in § 6.2.
7- Bleed the air from the cylinder (refer to § 4.8).
Check for proper functionning and any leakage.
Fill the reservoir with new hydraulic oil to its
proper level with the platform fully retracted.
6.5.4 Removal - Installation of the manifold
The cylinder manifold is located between the front
wheels of the machine. It includes a pressure relief
valve (protection against overpressure due to
overheating), a pressure compensated flow regulator,
and a manually controlled solenoid valve.
Before any maintenance on the manifold,
disconnect the machine from the electrical
power supply, disconnect the charger plug,
and ensure the power unit is off. Failure to
comply could result in death or serious
injuries.

2- Remove the coil from the solenoid. Ensure the
seals located on both sides of the coil do not get
lost.
3- Remove the solenoid.
4- Remove the plug and pressure compensated
flow regulator.
5- Remove the pressure relief valve.
6- Clean all parts that were removed and replace the
seals.
7- Reassemble the manifold assembly.
