2.3 Dangers when utilizing the compressed air grease gun

Attention!

Overpressure may cause damages of grease gun head and its accessories!

 Do not exceed the working pressure stated in chapter 1.3.

 We recommend the use of original accessories according to DIN 1283 only.

Attention!

Overpressure at the point of lubrication may destroy the grease nipple and perhaps even
the bearings or the machine itself!

 Do not exceed the working pressure stated in chapter 1.3.

 Please pay attention to the maintenance and service advices of the manufacturer of your

machine.

Status 25.02.2008 3

Compressed air grease gun Operating instructions

Attention!

Defective accessories can do damages to property and persons!

 High-pressure hoses may not be bent, twisted or stretched.

 Accessories will have to be checked for abrasion, cracks or further damages permanently.

 Defective accessories will have to be exchanged immediately.

 The utilisation period of the hose lines is 6 years max. after date of production (see

description on the hose).

3. Assembly

• The compressed air grease gun will be delivered completely assembled.

• Accessories will have to be mounted depending on the version used.

Note

When assembling the system, cleanliness and an exact connection of the accessories to the
grease gun head is required.

Please use suitable sealing material (e.g. Teflon film), only.

4. Initial or Repeated Operation

Check the completeness of the grease gun and the fixed accessories.

4.1 Filling of the compressed air grease gun

There are different filling options for the compressed air grease gun.

• Filling with a grease gun filling pump

• Filling with a grease cartridge acc. to DIN 1284

4.1.1 Filling with a grease gun filling pump

Attention!

Do not disassemble the grease gun unless having released the pressure before!

 Every time that the grease gun head and cylinder are to be separated, the push rod must be

fully retracted and automatically locked by means of the safety catch.

Grease gun with the nipple is to be put on the filling valve of the
filling system and kept with slight counter pressure.

Filling of the grease gun by operating the filling system (lever action
pump).

Pull on the push rod, actuate the safety catch, and push the push
rod back into the cylinder.

Operating Instructions Compressed air grease gun

4.1.2 Refilling of grease cartridge according to DIN 1284

Attention!

Do not disassemble the grease gun unless having released the pressure before!

 Every time that the grease gun head and cylinder are to be separated, the push rod must be

fully retracted and automatically locked by means of the safety catch.

Pull back the push rod and unscrew the grease gun head.

Remove the sealing cap from the full cartridge, and guide this into the
grease gun cylinder.

Only then tear off the cartridge's "pull-off" closure and screw on the
grease gun head.

Pull on the push rod, actuate the safety catch, and push the push rod
back into the cylinder.

4.2 Readiness for Service

Note

Check that the grease gun head and cylinder are tightly screwed together.

Remove air from the grease-containing section via the combined
filling / air removal nipple on the grease gun head by loosening
the gun head and cylinder (half a turn maximum) or by repeatedly
actuating the hand lever.

Connect the compressed air supply (max. 8 bar) to the
connection nipple located on the handle.

• The grease gun is now ready for use.

Status 25.02.2008 5

Compressed air grease gun Operating instructions

5. Betrieb

• Connect the hydraulic coupler of the
grease gun to the grease nipple.

• By pulling the trigger of the grease gun
the greasing work starts.

Caution:

Single-stroke grease supply is normally the
standard with pneumatic grease pumps.

One pull of the trigger delivers one single
stroke grease supply.

The automatic pneumatic grease pump
delivers a continuous grease flow.

While keeping pulling the trigger the
automatic grease pump delivers a continuous
grease flow.

Attention!

Overpressure may cause damages of grease gun head and its accessories.

 Do not exceed the working pressure stated in chapter 1.3.

 We recommend the use of original accessories according to DIN 1283 only.

Attention!

Overpressure at the point of lubrication may destroy the grease nipple and perhaps even
the bearings or the machine itself.

 Do not exceed the working pressure stated in chapter 1.3.

 Please pay attention to the maintenance and service advices of the manufacturer of your

machine.

Advise

Disconnect the quick coupler of the grease gun from the compressed air supply if the greasing
procedure has been achieved or if the pneumatic grease gun is not to be used for a while to
avoid an unintentional discharge of the grease cartridge or to prevent leakage.

6. Maintenance/Service

In general, the compressed air grease gun does not require much service and maintenance at
all.
Due to the operator’s duties the following parts will have to be checked regularly for function, to
avoid environmental and material-damages as well as personal harm:

• Grease gun head

• Screwed connections

• Accessories (high pressure hoses, couplers, etc.)
