Automatic Greasing System

Refilling the grease reservoir
4.5.1
Grease recommendations
Grease should not contain graphite or PTFE. The use of correct grease in the Twin-3 system is of
utmost importance. The use of grease with a maximum of 5
%
molybdenum disulphide (MoS2) is
permitted.
Groeneveld recommends the use of its GreenLube grease.
Consult your local Groeneveld dealer prior to change of grease (specifications) or any other inqui-
ries you may have.
The Twin greasing system is developed for use with grease up to NLGI-class 2. Which NLGI-class has
to be used, mainly depends on the temperature in which the greasing system has to operate:
4.5.2
Filling the reservoir
If the yellow LED and LO code at Twin-3 display lights up continuously or the signal lamp at the
duty mode push-button flashes for 2 minutes (0,5 sec. on/0,5 sec. off) at the start of each cycle, the
minimum grease level in reservoir has been reached. In this case the reservoir requires a refill as fol-
lows:
1.
When a new fillerpump or hose is used, ensure no air is left in it. Prime fillerpump and hose to
avoid air-pockets being pumped into Twin-3 pump reservoir;
2.
Remove the dust cap from the filler coupling;
3.
Carefully clean the filler coupling and coupling on the filler hose used;
4.
Fix the filler hose on the filler coupling;
5.
Fill the reservoir up to maximum level indicated on the reservoir;
6.
The bottom of follower plate should line up with max. level mark;
7.
Remove the filler hose and fit the dust cap;
8.
Fix the filler hose on filler coupling of the fillerpump, in order to keep the filler hose clean.

NOTE
The yellow LED and LO code at Twin-3 display or signal lamp of duty mode push-button will go
OFF automatically when pump reservoir has been refilled.
NOTE
Do not fill the reservoir until the low level warning comes on at the Twin-3 display or on the signal
lamp of the duty mode push-button switch.
NOTE
It is possible that during or directly after the refilling, some grease comes from the bleeding
opening of the pump (left side).
