JEFLUGGUN03
• To operate the grease gun simply push the grease outlet onto the
the grease nipple and operate the trigger until the desired
amount of grease has been dispensed.
• If you encounter air pockets during operation simply exert force on
the plunger, press the air vent valve (fig.2) and operate trigger
in short, sharp bursts until grease begins to flow from the nozzle.

WARNING! Disconnect gun from air supply before performing maintenance.
• Lubricate the air tool daily with a good grade of air tool oil. If the compressed air system has
no oiler, a few drops of oil can be poured into the air inlet of the gun each day.
• When not in use, disconnect from air supply, clean and store in a safe, dry, childproof location.
Note: Faults in the compressed air system may cause loss of power or erratic action. Reduced compressor output, excessive drain
on the air line, moisture or restrictions in air pipes or the use of hose connectors of incorrect size may reduce the air supply.
Grit or gum deposits in the tool will reduce power and may be removed by flushing out the gun with gum solvent oil or an equal
mixture of oil and kerosene.
Note: If the JEFLUGGUN03 is used with cartridges for a long period, it is possible that the rubber plunger may become damaged. If it is
then used with manual or bulk filling systems, the plunger may allow grease to seep from the bottom of the grease tube. To prevent
this happening, check the condition of the rubber plunger, and if worn, replace before using a different fill method.
