Maintenance
The instructions from the JOST IOMs for JSK 40 and JSK 42 still apply
to the fifth wheel coupling plate.
The LubeTronic
5Point
is maintenance-free. The grease supply sim-
ply needs to be replenished after about a year (special lubrication
not enabled). If the LubeTronic
5Point
is empty, this is indicated
by the LubeTronic
5Point
function lamp, see section 7.1 "Function
lamp".
In addition, inspect the connecting cable and lubricant lines of the
LubeTronic
5Point
once a year for damage. Damaged parts must
be replaced, as reliable operation can longer be guaranteed.
The grease cartridges are available from retailers.
You can find further information about JOST products on the JOST
website at www.jost-world.com.
8.1
Refilling the LubeTronic
5Point
To refill with the SKE 013 440 000 (2x 400 ml cartridge) or SKE
013 430 000 (barrel 25 kg) refill kits, a grease gun or barrel pump
must be used (feed pressure min. 25 bar, flow rate max. 250 grams/
minute or max. 4 grams/second). Any insufficiently lubricated
areas on the top of the fifth wheel coupling must be filled with
grease, for instance using excess grease from the second cartridge.
ATTENTION!
Only use JOST fully-synthetic, high-performance lubri-
cant or JHS2020B biodegradable, high-performance
lubricant to refill the LubeTronic
5Point
.
Uncouple the tractor unit, fold the JSK 34/JSK 37/JSK 42 fifth
wheel coupling completely forwards, or the JSK 38 model
completely backwards.
Clean the grease nipple on the LubeTronic
5Point
with a clean
cloth.
Position the grease gun on the grease nipple and fill the Lube-
Tronic
5Point
with grease. Make sure that grease does not
escape from the sides of the grease nipple. Fill with grease
until the plunger has been pushed to the “Maximum Grease
Level” mark.
Wipe off grease that has escaped during filling.
If available, trigger special lubrication until grease exits all
lubricating points on the fifth wheel coupling plate. Fill any
insufficiently lubricated areas on the top of the fifth wheel
coupling with grease.
Bring the fifth wheel coupling into its normal position.
Dispose of empty cartridges and packaging in accordance
with regulations in your country.
ADVICE!
If the LubeTronic
5Point
is overfilled, the excess grease
exits via a relief hole on the rear of the grease tank.
