4. Check and tighten bolts, nuts, and screws.
5. Check all cable sheaves/assembly for free movement or excessive wear on cable sheave shaft.
MONTHLY MAINTENANCE:
1.
Lubricate the inside of each column with gear grease.
2. With the lift in the lowered position, check the hydraulic fluid level. Add oil if necessary as
described in the Installation section of this manual.
3. Check synchronization of all four locks and assure they all click together. If necessary adjust
cables to synchronize as described in the Installation section of this manual.
4. Check tightness of all bolts, adjust if necessary.
5. Replace worn or broken parts with genuine Dannmar replacement parts.
YEARLY MAINTENANCE:
1. Lubricate the cable sheave shaft by using grease gun at lease once a year after the lift is in
service.
2. Check for excessive wear of cable. Replace them if necessary.
3.
Change the hydraulic fluid, good maintenance procedure makes it mandatory to keep hydraulic
fluid clean. No hard fast rules can be established; operating temperature, type of service,
contamination levels, filtration, and chemical composition of fluid should be considred. If
operating in dusty envir
onment shorter intervals may be required.
SPECIAL MAINTENANCE TASKS:
NOTE: The following items should only be performed by a trained maintenance expert:
1. Replacement of hydraulic hoses.
2. Replacement of cables and sheaves.
3. Replacement or rebuilding air and hydraulic cylinders as required.
4. Replacement or rebuilding pumps / motors as required.
5. Checking of hydraulic cylinder rod and rod end (threads) for deformation or damage
IMPORTANT:
Relocating or changing components may cause problems. Each component in the system must
be compatible. An undersized or restricted line will cause a drop in pressure. All valve, pump,
and hose connections should be sealed and/or capped until just 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.
