5. Check the cylinder pulley assembly for free movement or excessive wear on the
cylinder yoke or pulley pin.

Yearly Maintenance
1. Lubricate the chains
2. Grease the rub blocks and column surface contacting the rub blocks
3. Change the hydraulic fluid. It is an important maintenance procedure to keep the
hydraulic fluid clean. No hard fast rules though. Operating temperature, type of service,
contamination levels, filtration, and chemical composition of the fluid should be
considered. If operating in a dusty environment a shorter interval may be required.
Special Maintenance Tasks (performed by a trained maintenance expert only)
Replace the hydraulic hoses.
Replace the chains and rollers.
Replace the cables and sheaves.
Replace or rebuild the cylinders.
Replace or rebuild the pumps / motors.
Checking of hydraulic cylinder rod and rod end (threads) for deformation or damage.
CAUTION! Relocating or changing components may cause problems. Each component in the
system must be compatible. An undersized or restricted line may cause a drop in pressure. All
valve, pump, and hose connections should be sealed and/or capped prior to use. Air hoses
can be used to clean fittings and other components. However, the air supply must be filtered
and dry to prevent contamination. Most important is cleanliness. Contamination is the most
frequent cause of malfunction or failure of hydraulic equipment.
