We suggest that you re-torque the floor wedge anchors at least four times per year. If the anchor bolts pull up out of the concrete, the lift should be moved to another location or the floor should be repaired. Another alternative to wedge-style anchors is chemical anchoring, which can be purchased at most building supply companies. It is recommended that wire rope lifting cables should be lubricated once every 30 days with a non-stick penetrating oil that does not attract dust. The steel pulleys should also be sprayed at the same time. It is also recommended that every pivot point on the lift should be lubricated with light machine oil every 30 days. Lift arm pivot pins, lifting chains, and pulleys and lock release systems are examples of these components that should be re-lubricated. We recommend using a 30 or 32-grade hydraulic oil in your lift. Depending on the environment, the hydraulic oil should be replaced at least every 24 months of operation.
