Explanation of signal
words for safety
Read and carefully observe these instruc-
tions before loading, operating or trouble-
shooting. The grease gun must be main-
tained and repaired exclusively by persons
familiar with these instructions.
Use gun only after safety instructions in
this guide have been read and are com-
pletely understood.
Adequate personal protection must be
used to prevent splashing of material on the
skin or in the eyes.
This equipment generates very high
grease pressure. Extreme caution should be
used when operating this equipment as
material leaks from loose or ruptured com-
ponents can inject fluid through the skin and
into the body. If any fluid appears to pene-
trate the skin, seek attention from a doctor
immediately.
Do not treat injury as a simple cut. Tell
attending doctor exactly what type of fluid
was injected.
Any other use not in accordance with
instructions will result in loss of claim for
warranty or liability.
Do not misuse, over-pressurize, modify
parts, use incompatible chemicals, fluids, or
use worn and/or damaged parts.
Always read and follow the fluid manufac-
turer’s recommendations regarding fluid
compatibility, and use of protective clothing
and equipment.
Failure to comply may result in death or
serious injury.
NOTE
Emphasizes useful hints and recom-
mendations as well as information to
prevent property damage and ensure
efficient trouble-free operation.
CAUTION
Indicates a dangerous situation that can
lead to light personal injury if precau-
tionary measures are ignored.
WARNING
Indicates a dangerous situation that
could lead to death or serious injury if
precautionary measures are ignored.
DANGER

Description
Read Priming (page 4) prior to use.
All 555 grease-gun models have a
dual-leverage feature which allows them to
be operated in either volume or pressure
modes. With the link in the volume position,
the guns deliver 1 ounce (28.4 grams) of
grease in 30 strokes. Shifting the link to the
pressure position allows the guns to develop
7 500 psi (517 Bar).
The guns are capable of 3-way loading:
cartridge, suction, and loader pump
(requires optional loader fitting 306740 or
322610).
The guns are spring-primed and have an
air bleed valve to aid priming. The seals are
Buna-N (nitrile) for compatibility with petro-
leum based greases. Models 555CLR and
555CLR-E come with clear tubes for quick
grease-type identification.
WARNING
These guns can develop up to 7 500 psi
(517 bar) pressure.
Use safety glasses and gloves for pro-
tection during operation.
Failure to comply will result in serious
personal injury.

NOTE
Before gun can be loaded from a loader
pump, pipe plug (8) in head must be
replaced with a loader fitting (Alemite

Operation
1 Load and prime gun as required.
2 Wipe end of coupler (1) and fitting to be
lubricated with a clean cloth.
3 Attach coupler to lubrication fitting.
4 Operate lever (7) using either volume or
pressure mode until required amount of
product is dispensed.
5 Remove coupler from fitting with a side-
ways motion.
Loading
Cartridge Loading
1 Unscrew head assembly (5) from
cylinder (9) (†Fig. IPB 1, page 6).
2 Pull plunger rod (10) out, then slowly
return to eject empty cartridge.
3
Pull plunger rod out and engage groove on
plunger rod with slot in cylinder cap (12)
(†Fig. 2, page 5).
4 Remove plastic cap from grease cartridge
and discard.
5 Insert cartridge into cylinder (open
end first) until metal lip seats.
6 Remove tabbed seal from car-
tridge and discard.
7 Screw head assembly securely
onto cylinder.
8 Disengage plunger rod from slot in
cylinder’s cap. Push into cylinder.
9 Prime gun according to section entitled
Priming (page 4).
Use and operation
Priming
Overview
Priming is the act of removing air and intro-
ducing grease into the pumping mechanism.
Whether a gun primes is dependent on:
–viscosity of grease
–temperature of grease
–condition of gun
Force prime
With link in volume position, gun should
prime after operating lever several times.
Should grease fail to appear, head assembly
must be bled.
1 Pull plunger rod (10) out then rotate rod to
latch rod onto grease plunger (†Fig. 3,
page 5).
2 Push plunger rod while depressing air
bleed valve (4) to allow air to escape
(†Fig. 4, page 5).
3 Rotate plunger rod to unlatch from
grease plunger then push into cylinder.
Suction loading
1 Unscrew head assembly (5) from
cylinder (9) (†Fig. IPB 1, page 6).
2 Insert head of cylinder below surface
of grease.
3 Slowly pull plunger rod (10) outward from
cylinder cap until groove is visible. Engage
groove in plunger rod with slot in cylin-
der’s cap (12) (†Fig. 2, page 5).
4 Screw head assembly securely onto
cylinder.
5 Disengage plunger rod from cylinder cap.
Push plunger rod into cylinder.
6 Prime gun according to section entitled
Priming (page 4).
WARNING
Do not use a high-pressure grease fit-
ting as a loader fitting. Personal injury
can occur due to excessive pressure.
Loading from a loader pump
1 Wipe loader fitting with a clean cloth.
2 If gun is not completely empty, extend
plunger rod.
3 Seat loader fitting into loader coupler
(Alemite 306741) on loader pump.
4 Operate pump until groove on plunger rod
is visible.
5 Push plunger rod into cylinder.
6 Prime gun according to section entitled
Priming (page 4).

* Indique un changement.

Lisez et observez attentivement ces instruc-
tions avant de charger, d’utiliser ou de
dépanner. Le pistolet graisseur doit être
entretenu et réparé exclusivement par des
personnes familiarisées avec ces
instructions.
N’utilisez le pistolet qu’après avoir lu et
compris les consignes de sécurité de ce
guide.
Une protection individuelle adéquate doit
être utilisée pour éviter les éclaboussures de
produit sur la peau ou les yeux.
Toujours débrancher la source d’alimenta-
tion (électricité, air ou hydraulique) de la
pompe lorsqu’elle n’est pas utilisée.
Cet équipement génère une pression de
graisse très élevée. Il convient de faire
preuve d’une extrême prudence lors de l’uti-
lisation de cet équipement car des fuites de
matériau provenant de composants desser-
rés ou rompus peuvent provoquer l’injection
de fluide à travers la peau et dans le corps. Si
un liquide semble pénétrer dans la peau,
consultez immédiatement un médecin.
Ne traitez pas les blessures comme une
simple coupure. Dites au médecin traitant
quel type de fluide a été injecté.
Toute autre utilisation non conforme aux
instructions entraînera la perte de la garan-
tie ou de la responsabilité.
Ne pas mal utiliser, ne pas trop pressuri-
ser, modifier les pièces, utiliser des produits
chimiques ou des liquides incompatibles, ni
utiliser des pièces usées et / ou
endommagées.
Toujours lire et suivre les recommanda-
tions du fabricant du fluide concernant la
compatibilité du fluide et l’utilisation des
vêtements et équipements de protection.
Le non-respect de cette consigne peut
entraîner la mort ou des blessures graves.
