# 液压连接

Our hydraulic pumps are equipped with a zero-pressure relief valve. However, it could be possible that the retract side remain pressurized after the pump has been switched “off”. This trapped pressure prevents the user from loosening the retract-side fittings by hand. To release the pressure, simply push the black button on top of the solenoid. All fittings are free to be manually tightened.

Never disconnect or connect any hydraulic hoses or fittings without first unloading the wrench and the pump. If the system includes a gauge, double check the gauge to assure pressure has been released. When making connections with quick disconnect couplings, make sure the couplings are fully engaged. 如配件、仪表等螺纹连接处必须保持清洁、牢固拧紧且无泄漏。

警告

如果接头发生松动或未恰当旋紧，在加压时可能会产生危险。过度旋紧可能导致螺纹提早损坏。须要确保接头旋紧且不会发生泄漏。切勿抓取、触摸或以任何方式接触液压泄漏。漏油可穿透皮肤，进而造成伤害。
