Is pistol grip or lever action grease gun better?
For industrial applications with smaller bearings, a lever grease gun that produces higher pressure but less output volume is ideal. The pistol grease gun has less mechanical advantage and develops less pressure. … The pistol grip grease gun usually provides lower pressure (500 psi) and lower output per stroke.
How many ounces of grease are in a pump?
Answer: Generally, a shot of grease means one stroke from the grease gun. However, the output, or amount of lubricant dispensed from a grease gun depends on the model. Grease guns deliver widely varying amounts of grease (typically 0.1 ounce or 2 to 3 grams).

When should I stop greasing?
- Stop greasing if you note back pressure that is not normal.
- Check to see that the exhaust ports on a machine are free from debris, including hard crust.
- Slowly pump the lubricant into a machine’s bearings for several seconds.
Can you over grease fittings?
Use Just Enough: Don’t overfill when you grease Zerk fittings. Usually, three or four pumps of grease are enough and over-greasing a joint pushes grease out the aforementioned seals, which attracts dust, sand, and dirt. Contaminated grease can damage moving parts, so avoid having excess squish out the seals.
