Safety Instructions
Appropriate Use
 Use QLS 301 only for he delivery of lubrican s. The pump
is designed for in ermi en opera ion. QLS 301 is
designed of supplying lubrican o a maximum of 18 lube
points per y le.
 Do no use QLS 301 wi h SSV block in bo om moun ing
posi ion for mobile appli ations. Dont install the
pump in areas exposed to sho k.
General safety Instru tions
 Do no over pressurize reservoir when filling he pump.
Refill QLS 301 pump wi h clean lubrican .
 Incorrec use may resul in bearing damage caused by
poor or over-lubrica ion.
 Each ou le used mus be equipped wi h an appropria e
check valve see page 4, Fig.3.
 Don pain pump 301. Before pain ing machine or com-
mercial vehicle remove or cover he comple e pump.
 Unau horized modifica ions or changes o an ins alled
sys em are no recommended and will void warran y. Any
modifica ions mus be subjec o prior consul a ion wi h
he manufac urer of he QLS 301.
Regulations for prevention of a idents
 To preven acciden s, observe all ci y, s a e and federal
safe y regula ion of he coun ry in which he produc will
be used.
For pumps with 120 VAC and 230 VAC, swit h off the po-
wer supply before beginning maintenan e or repair work.
 QLS 301 opera es au oma ically. However, a regular
check (approxima ely every 2 weeks) should be made o
ensure ha lubrican is being dispensed from all lubrican
poin s.
 Used or con amina ed lubrican s mus be disposed of in
accordance wi h local environmen al regula ions, see
echnical da a shee s of lubrican s.
 The manufac urer of he cen ralized lubrica ion sys em
will no accep any liabili y for:
- damage due o he use of greases which are no or are
only condi ionally pumpable in cen ralized lubrica ion
sys ems.
- damage caused by insufficien lubrican and irregular
refilling of pump.
- damage caused by he use of con amina ed lubrican s.
- damage caused by inadequa e disposal of used or
con amina ed lubrican s.
- damage caused by unau horized modifica ion of sys em
componene s.
- damage caused by he use of unapproved par s (voids he
pump warran y).
Operation, Repair and Maintena e
 Repairs should only be performed by au horized
personnel who are familliar wi h he ins ruc ions.

Installation
 Do no remove, modify or al er any safe y equipmen
already ins alled on he machine.
 QLS 301 pump mus be kep away from he sources of
hea (see Opera ing Tempera ure Specifica ion).
 Follow ins alla ion ins ruc ions of he OEM regarding
minimum dis ances be ween he drilled holes and welding
procedures.
 Use following recommenda ions o selec an ins alla ion
loca ion:
- Keep he feed lines as shor as possible.
- Provide access o fill, clean and visually moni or he
pump opera ion.
 Ins alling QLS 301 pump wi h he reservoir uprigh is
perferred, bu pump may be ins alled wi h he reservoir in
horizon al wi hou affec ing i s opera ion.
 The QLS 301 may only be ins alled by qualified person-
nel. The connec ion (N/L/PE) of he supply vol age mus
be made according o VDE 0100 and VDE 0160.
 Ins all a pro ec ive and lock ou device for isola ing and
disconnec ing he QLS 301. Before beginning he
ins alla ion work, disconnec he elec rical supply .
 Failure o observe he safe y ins ruc ions, e. g. ouching
elec rically charged par s when he sys em is opened, or
improper handling of he QLS 301 may ause serious
injury or death.
 If he values specified in he Technical Da a are exceeded,
he device may overhea . I may damage he QLS 301
and hus impair he elec ric safe y.
Installation Instructions
Pump  Use drilling empla e o mark and drill moun ing holes of
he QLS 301. Drilling empla e and moun ing bol s are
included in he package.
SSV Divider Block Crossporting of the SSV divider blo ks
 The ou le s of he SSV divider block can be combined o
increase he amoun of lubrican for a par icular ou le . To
do his, simply plug he unused ou le s wi h he closure
plug (see Fig. 2), provided in he accessory ki .
 Lubrican from a plugged ou le is redirec ed o he nex
ou le on he same side of he SSV divider block in
descending numerical order (see Fig.1). For ins ance
plugging ou le s 5 and 3 will riple he amoun of lubrican
a ou le 1.
 Unused lubrican can be in ernally feed back o he
resevoir, see paragraph direc in ernal feed back fea ure
Do not plug outlet numbers 1 and 2 on SSV 8, 12 and

* Screw he Quicklinc fi ing in o he Zerk-Lock body and
igh en un il par s resis fur her igh ening (abou 1-1/2
urns).
 If he lines are no primed, prime all lubrica ion feedlines
before connec ing hem o he Zerk-Locks.
 Connec feedlines (dia. 6x1.5 mm, 1/4) from he check
valves direc ly o exis ing grease fi ings using he
Zerk-Lock fi ings included wi h he accessory ki .
Note: Push the end of the line firmly into the Quicklinc fitting
until it is fully seated in the body. The primed feedlines are
marked with white lines (Fig.9, 10 as an installation aid.
Fig. 8 - Screwing Quicklinc fi ing in o he Zerk-Lock body
Note: Quicklinc hex. is 12 mm. Zerk-Lock body hex is 1/2 .
* Move he Zerk-Lock and ube fi ing from side o side on
he grease fi ing o insure he Zerk-Lock is firmly sea ed.
Fig. 10 - Feedline inser in o he fi ing up o he nex whi e

 Cu he pressure plas ic ube off a one of he whi e lines
before i is moun ed. Then inser he plas ic pressure ube
in o he fi ing up o he nex whi e mark. This will ensure
a correc ins alla ion of he pressure plas ic ube in he
hreaded ube fi ing.
Connection of Feed Lines
 Measure, cu and rou e he feedlines included in he ki .
Avoid sharp bends of he plas ic ubing and he moving
par s of he machine ha could damage he lubrica ion
lines. Minimum bending radius is 50 mm (2 in).
 Secure he lubrica ion lines o he machine using nylon
ies, clamps or s raps provided in he accessory ki .
Fig. 9 - Feedline ins alled in he Quicklinc fi ing
* Cu he feedline off a one of he whi e lines before i is
moun ed.
* Then inser he feedline in o he fi ing up o he nex
whi e mark.
 This will ensure a correc ins alla ion of he feedline in
he ube fi ing.
Filling of reservoir
* Fill he reservoir wi h clean sui able lubrican .
* Expel all air from under follow pla e. Make sure ha he
follower pla e seal moves above he ven hole o ensure
ha all air pocke s are ven ed.
 When filling he reservoir by means of pumps with a
large delivery volume do not ex eed the max. filling
mark. Risk of bursting if the reservoir is overfilled.

Maintenance, Repair and Tests
 Main enance is essen ially limi ed o refilling he reservoir
wi h clean lubrican as necessary. However, check regu-
larly whe her he lubrican is being dispensed o all he
lubrica ion poin s.
 Also check he feed lines for damage and replace hem, if
necessary.
Swit h off the voltage supply for pumps 120 VAC and 230
VAC before servi ing the pump.
 For repair work on he QLS 301 use only Lincoln Indus ri-
al original spare par s.
 Using non-Lincoln Indus rial par s will void he pump
warran y.
Turn off the voltage supply for pumps 120 VAC and 230
VAC before servi ing the pump.
Important: To clean he sys em use pe roleum spiri or
pe roleum. Do not use Tri, Per or similar solvents or polar
or organi solvents su h as al ohol, methanol, a etone,
et .
Note: Whenever work is performed on the centralized
lubrication system, special attention should be paid to
cleanliness. Dirt will cause failure of the system.
 Fill he reservoir up o he Max. mark via he filling
nipple
Important! The grease mus be free from impuri ies and
mus no be liable o change i s consis ency over he course
of ime.
Note: If the reservoir has been completely emptied, the pump
may require priming and a longer running time to reach the full
lubricant output. Therefore, initate additional lube cycles
manually.
* Press push bu on o ini ia e a
lubrica ion cycle.
Filling of the empty reservoir
 Make sure, ha all air has been expelled from under he
follower pla e af er refilling he emp y reservoir.
* The follower pla e seal should clear he hole loca ed on
he op of he reservoir. Small amoun of grease should be
expelled o ensure expelling of air from under he follower
pla e.
1 - Filling nipple 3 - Follower pla e
2 - Ven hole
4222a99

* By opera ing he drive mo or wi hou he reservoir ins al-
led, here is a risk of injury by eccen ric gear.
When filling he reservoir by means of pumps with a large
delivery volume do not ex eed the max. filling mark. Risk
of bursting if the reservoir is overfilled.
