A grease gun you squeeze with one finger, not two hands

The Bluebow grease gun kit is a 21 V cordless gun with two 4.0 Ah batteries, a charger and a 39.4 inch flexible hose, all in a carrying case. The pump develops up to 12,000 PSI, which is the figure that matters on a fitting that has not seen grease since last season: the pressure clears the hardened plug so fresh grease can follow. The two kits in the range differ in flow, 5.3 and 7.05 ounces per minute, and in color, blue and teal.

The air bleeder valve is the small part you will use most. A gun that has just been loaded carries air pockets, and the bleeder lets them out before the first fitting, so the grease flows steadily instead of spitting. The flexible hose reaches pivot pins under a bucket and fittings behind a tire, and the LED under the head lights the fitting you are aiming at.

Treat 12,000 PSI with respect. Hand surgeons who study injection injuries report that it takes about 100 PSI to breach skin and that most high-pressure guns reach 2,000 to 12,000 PSI; the wound looks like nothing and the damage is underneath. Keep your free hand away from the coupler while the trigger is down, and read our grease gun guide before the first job.

The two kits side by side
Kit	Flow	Pressure	Batteries
Blue	7.05 oz/min	12,000 PSI	2 x 4.0 Ah, 21 V
Teal	5.3 oz/min	12,000 PSI	2 x 4.0 Ah

Flow and pressure are the figures each kit states for itself. The air bleeder valve is named by the teal kit.

This kit is part of the Bluebow releases, from $70.45 to $89.99 in our last catalog update.

Questions

About Bluebow cordless grease gun kits

How much pressure will your Bluebow grease gun develop?

Up to 12,000 PSI at the coupler, which is the pressure that clears a fitting plugged with hardened grease. The grease gun guide explains when the pressure is doing the work and when a fitting needs replacing instead.

Should you pick the blue or the teal Bluebow kit?

Flow. The blue kit moves 7.05 ounces of grease a minute, the teal 5.3. Both develop 12,000 PSI, carry a 39.4 inch flexible hose and ship with two 4.0 Ah batteries and a charger in a case.

How do you bleed the air out of a Bluebow grease gun?

After a refill, open the air bleeder valve named on the teal kit, pull the trigger until grease shows at the valve without bubbles, close it and go to the first fitting. The routine is written out in the grease gun guide.

Can the Bluebow grease gun injure your hand?

Any grease gun at these pressures can. Hand surgeons report that about 100 PSI breaches skin and that injection injuries look like nothing until hours later. Keep your free hand clear of the coupler and never check a leak with a finger; the grease gun guide has the sources.

This is general information about using cordless and hand tools, not instructions for your vehicle, machine or job site and not a substitute for the manual that comes with each tool. The manual, the torque or lubrication figures from the maker of what you are working on, and your own assessment of the job come first.

What the safety sources say

Dailiana et al., Injection injuries: seemingly minor injuries with major consequences, Hippokratia 12(1), 2008. Grease and oil are among the materials injected under the skin by high-pressure equipment; breaching the skin takes at least 100 psi while most high-pressure guns and injectors reach 2,000 to 12,000 psi, the puncture wound is small and easy to dismiss, most injuries hit the non-dominant index finger through inexperience with the equipment, and the risk of amputation is lower when surgical cleaning happens within six hours.

OSHA, 29 CFR 1910.147: The control of hazardous energy (lockout/tagout). Servicing and maintenance means activities such as adjusting, inspecting, maintaining and servicing machines or equipment where an employee could be hurt by unexpected start-up or release of stored energy; the standard applies to such work whenever a guard comes off or a body part goes where it could be caught.
