The sequence of actions for elevation wheel when using the jack shown in Fig. 10.2:
1. Brake the vehicle with the parking brake, shift into the first or reverse gear of the gearbox, making sure that the
transfer case gear lever is not in the neutral position. Place chock block under the front and rear wheels on the opposite
side.
2.
Install the jack on a level ground under the axle shaft case.
3Unscrew internal jack screw 3 as high as the clearance between the axle shaft housing and the ground allows. The
base of the jack is designed to work on hard surfaces and soils. Therefore, to prevent the fall of the jack on eroded, loose
soil, snow, loose sand, place a piece of board, plywood or other solid material with a size of about 250x250 mm.
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. Insert the handle of the standard wheel wrench into the pipe of the ratchet gearing and ensure by swinging the
resulting tommy bar clockwise in the horizontal plane with a force through throw-over stop that the vehicle wheel is lifted
up to the required height.
6.
To lower the wheels, move the jack “pawl” to the right and deepen the jack screws into housin
g 1 by jigging
motion of the wheel nut wrench. At the end of work, twist external screw 2 and internal screw 3 into the housing up to the
stop.
Maintenance of jacks
amounts to periodically cleaning it of mud and lubricating its threaded parts.
Monitor the condition of the screws and jack levers. No deformation or damage to screws and levers is allowed. In
this case replace the jack.
Vehicular-mounted winch+
A vehicle winch powered by an on-board battery and a generator is designed to pull out your vehicle from mud and
make it easier to move, and to pull out other vehicles or loads while yours will be "anchored" in a stationary position (Fig.
10.3).
The winch is controlled by a remote control console connected to the electric terminal from the winch control unit.
To use the winch, connect the positive power supply wire to the "+" terminal of the battery with the thumb screw.
When you don't use hauling winch any more, disconnect the positive power lead.
All necessary information on the operation and maintenanc
e of the winch are given in the manufacturer’s
instructions (manual) attached to the vehicle.
