Raising and Lowering
Speed lift without load
By activating the automatic or manual speed control (
B
or
C
) the ram moves up to
engage the load (axle, gearbox). Depending on the air pressure and the lift achieved,
the ram rises a little further after releasing the button.
Lifting the load
The load is lifted by activating the automatic or manual / foot operated lifting control
(
D
or
E
).
Lowering under load
When lowering under load, the lowering valve may only be opened slowly by turning
the release spindle
(A)
to the left in order to achieve a controlled descent.
Lowering without load
Open the release spindle
(A)
by turning to the left as far as possible. This actuates the
lowering valve and the rams are retracted.
