Installation Guide
Disconnect hydraulic power source before operation, release residual hydraulic pressure to guarantee operation safety.
Clean hydraulic ports, connecting surfaces and mating accessories thoroughly, remove dirt and metal debris to prevent impurities entering hydraulic circuit.
Inspect new 6V‑3170 puller cylinder for deformation, piston‑rod scratch or seal damage before mounting.
Correctly connect puller cylinder with matched hydraulic pump and puller accessories, check all connection fittings.
Perform low‑pressure trial operation first, check sealing condition, then carry out formal pulling‑disassembly work.
Maintenance Tips
Inspect cylinder surface, piston‑rod and hydraulic joints for oil leakage before every use.
Protect exposed piston‑rod surface, avoid gravel scratch and corrosion which will damage internal seals.
Use clean specified hydraulic oil; do not exceed the maximum working pressure of the puller cylinder.
When replacing the puller cylinder, inspect matched hydraulic pump, hoses and connectors; replace worn supporting components synchronously.
