Routine maintenance
1. Avoid continuous rise or fall during use. Rise and fall should not be switched quickly and continuously, which will easily shorten the service life of the motor and hydraulic pump.
2. Check the oil level in the fuel tank regularly. If the oil level is lower than the bottom line, you need to add oil. If the oil color becomes dark and turbid, you need to consider replacing the oil.
3. It is strictly forbidden to raise if there is a vehicle or pedestrian above the road pile to avoid danger.
4. Keep the bottom of the pile on the hoistway clear and clean around, to ensure the service life and performance of the lifting pile parts and waterproof sealing.
5. On large ice and snow days, if there is severe icing inside the column, lifting is prohibited. It can be used after thawing by heating.
