ASSEMBLY

PUMP HEAD EXTENSION NOZZLE

1. Connect the extension nozzle (4) to the grease outlet on the pump head (2).
2. Screw the coupling nipple (3) in the outlet end of the extension nozzle (4).
3. Wind thread tape on the threads on the extension nozzle (4) before fitting it in the grease outlet in the pump head (2) and before the coupling nipple (3) is screwed on the extension nozzle (4).
4. Tighten all the connections firmly in place.

IMPORTANT: The feed spring pressurises the grease or grease cartridge. Be careful when removing the pump head from the cylinder.

The grease gun can be filled in three ways:

• By inserting a grease cartridge Manual filling of bulk grease
• Suction filling – manual suction of bulk grease.

The preparations below should always be carried out before filling the grease gun, regardless of which filling method is used.

1. Where appropriate first remove the empty grease cartridge from the cylinder (1).
2.  Pull out the piston rod handle (6) all the way and lock in this position.
3. Unscrew the pump head (2) anticlockwise and remove.
4. If there is an empty grease cartridge in the cylinder, remove it.

Inserting a grease cartridge

1. Pull back the piston rod handle (6) all the way.
2. Remove the pump head (2) from the cylinder (1).
3. Put the grease cartridge in the cylinder
4.  with the open end facing inwards. Press the grease cartridge all the way into the cylinder.
5. Pull off the seal on the end of the cartridge.
6. Refit the pump head (2) on the cylinder (1).

Manual filling of bulk grease

1. Pull back the piston rod handle (6) all the way.
2. Remove the pump head (2) from the cylinder (1).
3. Fill the cylinder (1) with grease with a spatula or equivalent.
4. Refit the pump head (2) on the cylinder (1).

Suction filling – manual suction of bulk grease

1. Remove the pump head (2) from the cylinder (1).
2. Press down the open end of the cylinder
3. about 5 cm below the surface in the grease container, pull back the piston rod handle (6) and lock in this position.
4. Refit the pump head (2) on the cylinder (1).

IMPORTANT: Do not screw the pump head too tight on the cylinder or the extension nozzle too tight in the pump head outlet – risk of cracking the die casting.

BLEEDING

When filling with grease there are often pockets of air in the grease. Bleed in accordance with the following instructions.

Standard procedure

1. Do not fully tighten the pump head after filling with grease by one of the above methods – leave two to three turns.
2. Move the piston rod (7) back and forwards to expel any pockets of air. Release the piston rod (7). Press the piston rod handle (6) into the cylinder.
3. Screw the pump head (2) fully onto the cylinder (7).
4. The grease gun is now ready to use.

Procedure for grease guns with bleeder valve

1. Refit the pump head and screw tight after filling with grease by one of the above methods.
2. Tap the bleeder valve (8) to release enclosed air.
3. Move the piston rod (7) back and forwards to expel any pockets of air.
4. Tap the bleeder valve (8) again to release enclosed air.
5. The grease gun is now ready to use.

HOW TO USE

1. The coupling nipple (3) in the outlet end of the extension nozzle (4) has clamping jaws. They lock on the grease nipple and maintain a pressure-tight connection.
2. Fit the coupling nipple (3) straight and centred on the grease nipple and press until the coupling nipple clicks in place.
3. Continue holding the coupling nipple (3) as straight as possible in relation to the grease nipple and pump with the lever (5).
4. After greasing, release the coupling nipple (3) by angling it a little, twisting and pulling back ..
5. The combined angling and twisting makes it easy to pull the coupling nipple (3) off the grease nipple.

1. Press straight to connect
2. Angle, twist and pull to disconnect

MAINTENANCE

Always check before use that the grease gun is clean and undamaged.
