Pressure and runtime
- High pressure. Milwaukee's manual rates it at 8,150 psi, with a hose rated to 10,000 psi.
- Three ways to load. Cartridge, bulk suction or bulk pump loading.
- Quick priming. An air bleeder valve gets grease flowing fast.
- Easy to carry. Onboard hose storage, fuel gauge and a shoulder strap loop.
Purge it first. Milwaukee factory-tests every gun, so some test grease is still in the pump, hose and coupler. Run your own brand of grease through before real work.
Loading a cartridge
- Remove the battery, pull back the rod and lock it in the retaining slot.
- Unscrew the cylinder, uncap the cartridge and insert it open end first.
- Remove the cartridge seal and screw the cylinder back on.
- Release the rod, push it fully in and reinsert the battery.
- Prime: pull the trigger for 3 seconds, release and repeat until grease flows.
