Fill the cylinder with a penetrating solvent, seat it over the clogged fitting, then use short, firm taps to force fluid into and through the obstruction. Built from heavy-duty components with an adjustable hydraulic coupling and piston knob, it’s designed to reduce downtime on maintenance jobs.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the OTW tool actually clear a blocked grease fitting?\u003c\/h3\u003e\n\u003cp\u003eThis cleaner combines penetrating fluid and hydraulic pressure to break up hardened grease. The operator fills the cylinder with solvent, places the nozzle over the fitting, and taps the piston to drive the solvent into the zerk. Repeating this process flushes softening grease and debris out of the channel.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUse a compatible penetrating oil or solvent in the cylinder.\u003c\/li\u003e\n  \u003cli\u003eSeat the heavy-duty adjustable coupling firmly on the grease zerk.\u003c\/li\u003e\n  \u003cli\u003eTap the piston with a lightweight hammer in short, controlled strikes.\u003c\/li\u003e\n  \u003cli\u003eRepeat until lubricant or solvent runs clear from the fitting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this damage bearings or sealed components?\u003c\/h3\u003e\n\u003cp\u003eThe OTW grease buster is intended for open fittings, pins, shafts, bushings, and joints—not for sealed bearings or assemblies where internal seals could be compromised. The device applies localized hydraulic force; avoid using it on precision-sealed components to prevent leakage or seal damage.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eNot recommended for sealed or preloaded bearings.\u003c\/li\u003e\n  \u003cli\u003eSafe for external zerks, grease lines, and exposed bushings when used as directed.\u003c\/li\u003e\n  \u003cli\u003eOperator control of tapping intensity reduces risk to fragile parts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat steps ensure effective and safe use?\u003c\/h3\u003e\n\u003cp\u003eFollow a predictable routine: remove the piston to pour in solvent, reinsert and seat the tool, then deliver short taps — the aim is to dissolve the clog rather than blast it. Wear eye protection, use appropriate solvent, and hold the coupling steady for a tight seal during each tap sequence.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStep 1: Remove piston; fill with penetrating fluid; reinstall piston.\u003c\/li\u003e\n  \u003cli\u003eStep 2: Place tool over clogged fitting; ensure a snug connection.\u003c\/li\u003e\n  \u003cli\u003eStep 3: Tap piston lightly and repeatedly with a hammer; observe outflow.\u003c\/li\u003e\n  \u003cli\u003eStep 4: Repeat until the grease line clears and fresh grease flows freely.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat accessories and maintenance improve performance?\u003c\/h3\u003e\n\u003cp\u003eThe OTW model accepts hose extensions and can be paired with a pneumatic piston for heavier-duty applications. Regularly inspect seals and the coupling for wear, and clean the cylinder after each use to avoid contamination between solvents or greases.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with hose extensions and pneumatic pistons for greater reach or force.\u003c\/li\u003e\n  \u003cli\u003eWipe and flush the cylinder after use to prevent residue buildup.\u003c\/li\u003e\n  \u003cli\u003eReplace worn coupling seals to maintain a tight, leak-free fit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? Maintenance technicians, fleet mechanics, farmers, equipment owners, and shop professionals who service heavy machinery or vehicles will find this tool useful for restoring flow to stubborn grease zerks. It’s suited to anyone who needs a portable, repeatable method to clear dried lubricant from external fittings and joints, shorten repair time, and avoid replacing parts prematurely. Not intended for sealed bearings—use caution and follow the four-step tapping process for best results.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use the OTW cleaner with any solvent?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Use compatible penetrating oils or grease solvents—avoid corrosive chemicals.
