14.1.2 Hydraulic system, bleeding
1. Put the truck program in service mode and activate the service po-
sition for bleeding. The bleeding position initiates pump motor star-
tup and simultaneous opening of both the lift and the lowering
valves. The pressure in the valve block will reach around 1 MPa (10
bar).
2. Open the bleed nipple on the main lift cylinder approximately 2
turns. If the bleed nipple cannot be reached from the operator com
-
partment, use a ladder or similar item leant up against the mast.
3. Once all the air has been removed from the cylinder, oil begins to
drip out.
After 4 – 5 drops the bleed nipple must be closed.
4. Repeat bleeding on the other main lift cylinder.
5. Quit the truck program’s service position for bleeding.
6. Activate the service position for separate operation of free lift and
main lift.
7. Operate free lift (NOTE! NOT main lift) between maximum height
and the fully lowered position 3 – 4 times to drain the air in the free
lift cylinder into the tank. End with the mast in its fully lowered posi
-
tion.
8. Quit the truck program's service mode.
9. Check the oil level in the tank and top up as necessary to the right
level.
