What to do if there is oil leakage in my Stenhoj MOLNAR SM Lifting Systems?
If you notice oil leakage in your Stenhoj Lifting Systems, there are several possible causes. The high pressure hose might be defective and needs replacement. Alternatively, there could be leaks at the fittings, which can be resolved by tightening them. Lastly, the cylinder seals might be defective, requiring you to replace or repair the cylinder.
Why does the platform descend when ratchets are not engaged in my Stenhoj MOLNAR SM Lifting Systems?
If your Stenhoj Lifting Systems platform descends when the ratchets are not engaged, it could be due to leaks in the hydraulic system. Refer to the oil leakage information provided. Another possibility is a leaking lowering valve or non-return valve internal to the pump unit, in which case you should contact an authorized service technician.
What to do if the pump unit delivers insufficient pressure in my Stenhoj MOLNAR SM?
If your Stenhoj Lifting Systems pump unit delivers insufficient pressure, it might be due to a defective pump, which will need replacing. Another cause could be air in the hydraulic system. You can attempt to resolve this by lowering the platforms to the bottom position without any load and keep pressing the DOWN button for approximately 20 seconds. If this doesn't work, the non-return valve or oil pressure relief valve may be defective internally within the pump unit, requiring you to contact an authorized service technician.
Why is there an unusually high noise level in my Stenhoj MOLNAR SM?
An unusually high noise level in your Stenhoj Lifting Systems could stem from several issues. The pump might be worn and require replacement. Ensure that the hoist is not overloaded, referring to the decals for maximum load limits. A defective seal in the high-pressure cylinder might also be the culprit, necessitating cylinder replacement or repair. Check that the post position is correct according to the installation instructions. Finally, the oil pressure release valve might be out of adjustment, requiring adjustment to the correct setting.
What to do if my Stenhoj MOLNAR SM hoist cannot ascend?
If your Stenhoj Lifting Systems hoist cannot ascend, it might be due to overloading. Check the decals for the maximum load. It could also be due to insufficient pressure from the pump unit; refer to the pump information for further troubleshooting.
What to do if my Stenhoj MOLNAR SM hoist cannot descend?
If your Stenhoj Lifting Systems hoist cannot descend, there are a couple of potential reasons. First, the pump might not be starting; refer to the pump information for troubleshooting. Alternatively, one or more of the ratchets might still be activated. Ensure you lift the system free from the ratchet rails before attempting to lower it.
Why can't my Stenhoj MOLNAR SM hoist reach the topmost position?
If your Stenhoj Lifting Systems hoist cannot reach the topmost position, check the oil level in the tank and fill it up if it's insufficient. Also, the cable adjustment might be incorrect (too long), requiring you to adjust the cable.
What to do if the pump unit cannot start in my Stenhoj MOLNAR SM?
If your Stenhoj Lifting Systems pump unit cannot start, first check the fuses for any electrical failures. If the fuses are fine, the electrical connections may be incorrect, requiring you to call an authorized electrician. Other potential issues could be a fault in the control box or a faulty electric motor. Lastly, a defective pushbutton might be the cause, and you should replace it.
What to do if the control to lower hoist from topmost position does not release ratchets in Stenhoj MOLNAR SM?
If the activation of control to lower hoist from topmost position does not release ratchets in your Stenhoj Lifting Systems, it could be that one or more of the cables have stretched. In this case, you should adjust the cables.
Why are the platforms no longer horizontal when hanging in cables under load on my Stenhoj MOLNAR SM?
If the platforms are no longer horizontal when hanging in cables under load for your Stenhoj Lifting Systems, it could be because one or several cables have stretched. To resolve this, you will need to adjust the cables.
