Features

• Industrial Strength Build: Constructed with a heavy-duty alloy steel body designed for consistent, long-term performance under punishing conditions.
• Superior Pressure Capacity: Easily delivers up to 4000 PSI of operating pressure to power through clogged, stubborn, or deep-set grease fittings.
• Controlled Output Delivery: Engineered with a 5/8-inch precision piston that dispenses exactly 2 grams of grease per manual stroke for highly accurate applications.
• Smooth Ergo Actuation: Utilizes a specialized V-type pulling rod assembly that maximizes mechanical leverage, dramatically cutting down user hand fatigue during long service hours.
• Efficient Loading & Purging: Integrated lock lever mechanism permits quick, hassle-free grease cartridge swaps and reliable air pocket bleeding.
• Universal Fitting Utility: Ideal for maintaining critical moving parts in heavily exposed environments like construction fields, agricultural zones, and automotive repair stations.

Applications

• Automotive Servicing: Lubricating chassis joints, ball joints, tie rod ends, wheel bearings, and universal joints on consumer and commercial vehicles.
• Agricultural Equipment Care: Maintaining tractors, harvesters, combines, and heavy implements subjected to high friction, dust, and moisture.
• Construction Site Upkeep: Servicing heavy machinery links, excavator arms, bulldozers, cranes, and concrete mixing infrastructure.
• Industrial Plant Maintenance: Greasing conveyor bearings, manufacturing assembly line tracks, industrial pumps, and electric motor bearings.

Usage

• Cartridge Insertion: Pull back the V-type rod completely to engage the automatic lock lever mechanism, unscrew the barrel head, insert a fresh grease cartridge, and thread the barrel firmly back onto the head assembly.
• Bleeding Air Pockets: Release the lock lever and gently depress the air bleeder valve or slightly loosen the barrel thread while pumping to release trapped air pocket blockages.
• Fitting Connection: Clean the machinery grease nipple thoroughly, press the grease gun coupler squarely onto the fitting until it snaps firmly into place, and hold it securely.
• Pumping Action: Apply steady, rhythmic downward strokes to the main lever handle to deliver the 2 grams per stroke output safely into the fitting.
• Disengagement: Slightly tilt the coupler sideways to release the internal jaws from the zerk fitting after the required lubrication amount is met.
