Grease Gun Calibration

Before lubricating the sprayer, you must calibrate your grease gun to ensure that the correct amount of grease is applied to
each lubrication point. The correct amount of grease applied will prolong the lifetime of the sprayer.
Calibration example
1. Insert the correct grease cartridge in your grease gun.
2. Apply grease onto a tissue or a piece of paper. Complete 10 full
strokes of the grease gun.
3. Place the paper with grease on a scale (A).
4. If your grease pile weighs for example 10 grams, then 1 stroke
equals 1 gram of grease.
When calibrated, you can count how many strokes to complete, when
lubricating the different grease points on the sprayer according to the
specifications.
Alternative method
1. Count the strokes, until you have 10 grams of grease piled up on
the scale (A).
2. Now you can figure out how many strokes to use for applying a
certain amount of grease to a lubrication point.

ATTENTION! The correct amount of grease applied at the intervals is important. Too little or too much grease will
shorten the lifetime of the PTO.
The amount of grease to be applied is mentioned in grams (g). Test your grease gun to see how many grams it provides, for
example after 5 strokes.
The grease points and amount of grease to be applied are shown in the pictures below together with the intervals.
