Installation and Operation Instructions
Installing Zerk-Locks onto grease fittings (for inch size
accessory kits only)
The Zerk-Lock fitting consists of the Zerk-Lock body, an
insert and a Quicklinc fitting.
* Place the Zerk-Lock body over the grease fitting and
place the staking tool firmly against the Zerk-Lock insert.
(Staking tool is included in the accessory kits, see page
8).
* Strike the tool sharply with a hammer until the Zerk-Lock
insert partially crimps onto the grease fitting.

body over the grease fitting

backside mounted SSV divider blocks
Check valves
Important:
One complete check valve must be installed in
each outlet port hole used, see Figs. 1 & 4 to avoid draining
the oil reservoir.
* For feedlines (dia. 6x1.5 mm, (1/4) I.D., provided in the
accessory kits) use check valves with standard collar and
knurled flange.

Installing Quicklinc fittings into lube points
(for metric size accessory kits only)
* Remove hydraulic lube fittings from lube points and
install appropriate Quicklinc fittings into the bore holes of
the lube points.
Return of lubricant quantities
All QLS pumps with the
back mounted SSV divider block
(vertical outlets) have the capability to return unused
lubricant from the distributor block directly to the reservoir
internally
.
To achieve this automatically,
outlet 2 has to be closed
with a closure plug (
see Fig. 4). Lubricant quantities of
pair and impair outlets are returnable via the connection
of outlets 1 and 2.
For returning, always start with the oulets with the lowest
outlet numbers, i.e. 2, 4, 6... or 1, 3, 5...
plus outlet 2
. As
shown in Fig. 4, the lubricant from outlets 1, 2 and 4 (3xR)
will be internally returned to the reservoir.
The remaining outlets are to be used for the connection
to the lube point or to increase the lubricant quantity
(double or triple).
Important:
If
outlet 2
is connected to a
lube point
,
outlet 1
must not be closed
, see Fig. 1.
Note: To return unneeded lubricant quantities from
bottom
mounted divider blocks,
connect unneeded outlet via feed-
line to return plug 5 (Fig. 15) for
external
return.
