Use of equipment
- Especially when using extension hoses in hot conditions, keep a pressure relief valve nearby. If temperatures rise, the pressure in the hoses will increase. This may make it difficult to connect the hoses and pressure has to be released first.
- If you do not use your hydraulic rescue equipment very regularly, it is best to start your pump once a week and run it for a short while.
If a pump is not used regularly petrol in the carburettor will evaporate, letting moisture seep in. If this happens the pump will of course still work, but it may take longer to start it.
If you know beforehand that you are not going to use the pump for a while, ask your Holmatro dealer for special additives to add to the petrol. These additives will prevent the petrol from thickening which may affect the system.
- It is best not to close your hydraulic rescue tools entirely after use. If you close the arms or blades entirely pressure can remain in the system. This may make it hard to reconnect the hoses if you want to use the tool again. Pressure would have to be released first (with a pressure release device). To save time we advise you to leave the blades or arms slightly open, even 1mm will do. This is best achieved by stopping the spreader while closing the arms.
- When connecting hoses, tools and pumps, always check whether tools have been coupled correctly by pulling the couplers apart a little. This will prevent unnecessary leakage of oil.
- When cutting with a hydraulic combitool or cutter, try to cut as close to the central bolt as possible. Any cutter or combitool generates its highest cutting force near the main bolt. It depends on the brand and type of cutter (blade) you are using how much force the tool is able to generate on other parts of the blade.
- When you finish using a pump, first switch off the pump, then shut the petrol tap. This prevents the carburettor from running dry.
