Grease Nipple
When lubricating the sprayer, please use a greasing gun which fits the
dimensions of the grease nipple.
μ
ATTENTION! If grease is leaking from the nipple near its threaded
part, when grease is being applied, please tighten the nipple by
using a spanner or similar. Replace the nipple, if it is damaged or
bent out of shape.
μ
ATTENTION! If applying grease into the nipple seems difficult,
unscrew the nipple. Check if the nipple is blocked inside, or if the
spring-loaded ball is stuck. Clean or repair as needed.
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.
