4. Throw latch 5 over the jack to the left-hand side, relative to
the jack handle 6, so that latch projection enters the tooth space
of the ratchet wheel 7.
5. Lift the motor vehicle to required height by swinging the
wheel nut wrench inserted into the handle orice.
6. To lower the wheels, move the jack “pawl” to the right and
deepen the jack screws into housing 1 by swingings the wheel nut
wrench. At the end of work, twist external screw 2 and internal
screw 3 into the housing up to the stop.
To lift the wheels with the rhombus jack in Fig. 10.2, do the
following:
1. Brake the vehicle with the parking brake, shift into the rst
or reverse gear of the gearbox, making sure that the transfer case
gear lever is not in the neutral position. As required, put wedges
under the wheel, which is opposite to the jacked up wheel.
2. Install the jack on a level ground under the axle shaft sleeve.
3. Lift the motor vehicle wheel to the necessary height by rotat-
ing hexagon 1 or yoke 2 clockwise with the “22” mm nut wrench
or with extension 3.
4. To lower the wheel, rotate hexagon 1 counter-clockwise with
the wheel wrench. At the end of work, fold the jack completely
by rotating the hexagon with the wrench.
Maintenance of jacks amounts to periodically cleaning it of
mud and lubricating its threaded parts.
Inspect the riveted couplings, screws and levers of jacks. Screws
and levers deformation or damage, as well as riveted couplings
loosening are not allowed. If present, replace the jack.
