The jack (Fig. 70) is designed to jack up the automobile
wheels for maintenance. The jack load-lifting capacity is 2 t. The
maximum height of lifting is 240 mm.
For jacking up the wheel, proceed as follows:
1. Install the jack on a level ground under the axle shaft
sleeve.
2. Turn out the jack internal screw 3 as high as the clearance
between the axle shaft sleeve and the ground permits.
3. Throw over the jack latch 5 to the l.h. side relative to the
jack handle 6 so that the latch projection enters the tooth space
of the ratchet wheel 7.
4. By stroking the tyre iron inserted on the hole of the jack
handle, lift the automobile wheel to a required height.
For jacking down the wheel, throw over the jack latch to the
r.h. side and by stroking the tyre iron, jack down the wheel. After
work is over, turn the internal 3 and external 2 screws in the jack
body as far as they will go.
Maintenance of the jack amounts to periodically cleaning it
of dirt and lubricating the external and internal screws.
