Air Supply
Recommended hook-up is shown in g.1.
• Ensure that the trigger is in the OFF position when connecting to the air supply.
• WARNING! Ensure that the air supply is clean and is between 60-150psi. Too high an air pressure and/or unclean air will shorten the life of the
gun due to excessive wear, and may be dangerous, causing damage and/or personal injury.
• Drain the compressor air tank daily. Water in the air line will damage the gun.
• Clean compressor air inlet lter weekly.
• Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose size should be 1/4” internal
diameter and ttings must have compatible dimensions.
• Keep hose away from heat, oil and sharp edges. Check hose for wear and make certain that all connections are secure.

Priming the Grease Gun
• Before loading the grease gun with a cartridge or lling via a grease
bucket, it is ideal to prime the gun.
• To prime the gun simply pack grease into the cavity located
at the entrance of the gun assembly (where the grease tube screws
into the gun) and operate the trigger, this will induce the intake of
grease into the gun assembly.
Cartridge Loading (see diagram)
• Remove the gun head from
the grease tube.
• Fully draw back the
plunger handle.
• Insert the open end of the
cartridge into the grease tube
and push it all the way in. Remove
the seal or pull tab end from
the cartridge.
• Reassemble the gun head to the
grease tube. Press the catch plate
and release the plunger rod. Push
down on the plunger handle. Cartridge loading
Fig.1
Suction Filling
• Remove the gun head from
the grease tube.
• Submerge the open end of the
grease tube into grease bucket
by approximately 50mm and
slowly pull the plunger handle
out fully.
• Reassemble the gun head to
the grease tube. Press the
catch plate and release the
plunger rod. Push down on the
plunger handle.
Loading with Filler Pump
• Fully draw back the
plunger handle.
• Insert bulk loader valve (g.2)
into ller pump socket.

• 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.

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 ushing 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 lling 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 ll method.
