Поддомкрачивание and towage

Поддомкрачивание

For performance of many operations on maintenance service and car repairs he is necessary for lifting and establishing on two or four strong supports. On HUNDRED car, as a rule, rises the lift.

If under the car any works are made, the car is necessary for fixing reliably. Application of an onboard jack is admissible only at replacement of wheels. Carrying out of repair and other works under the car in this case is forbidden. It is life-threatening!
Lift only not loaded car. Establish supports under the bottom.

Points of lifting and support of an automobile jack

On the bottom longeron of a body there are the characteristic places designating an arrangement of forward and back nests for installation of a jack (an arrow on an illustration). To each wheel there corresponds only one nest. It is not supposed поддомкрачивание in other places. The distance from a nest for installation of a jack to a corresponding lobby of a wheel arch makes about 15 sm, and to back nearby 25 see

Points of lifting and support of an automobile jack

Establish a jack under the bottom beam and, rotating the handle, deduce its elevating paw on such height that the paw was directly under vertically located edge of a longeron.

Level a jack so that кулачковый capture of an elevating paw () covered a longeron edge, and a mobile heel () rested all surface against the basis.

Jack

Rotation of the handle of a jack lift the car to a separation from the earth of a faulty wheel.

Under the wheels which have remained on the earth, enclose wedges to exclude car moving. Do not rely on a lay brake. At performance of some repair work the lay brake is released.

Reference points for the lift and the garage lift

For an exception of damages to the bottom part of the car it is necessary to enclose rubber or wooden linings. At all it is not necessary to lift the car, leaning against the power unit, the pallet картера, forward or back suspension brackets since it can lead to serious damages.

Points of support in front. Are on vertical strengthening of the bottom beam at height of a label for an onboard jack. Strengthening of the bottom beam should be in the centre of a basic plate of the lift.

Points of support in front

Points of support behind. Are on vertical strengthening of the bottom beam around a stamped label (the marksman on an illustration) for an onboard jack. Strengthening of the bottom beam should be in the centre of a basic plate of the lift.

Points of support behind

Towage

Broad-brush observations

The car should be towed only for the eyes specially provided for this purpose.

Requirements of "traffic Rules» concerning towage should be observed.

The towing cable should be elastic not to damage both cars. It is necessary to use only a cable from synthetic fibres or similar elastic materials. However it is more safe to use a towing bar!

It is necessary to watch constantly that did not arise it is inadmissible the big tension, and at the same time there was no considerable resistance качению the car.

At car towage on dirt road edge always there is a danger of a pulling down on a roadside.

Before to try to start the engine towage, it is necessary to use whenever possible the storage battery of other car for engine start – address to corresponding section.

Both drivers should know features of driving at the towage, stated more low, and to have sufficient experience. Not skilled drivers should not be at the wheel any, other car.

At use of a towing cable the driver of the towing car should at трогании from a place and a gear change especially smoothly to release a coupling pedal.

The driver of the towed car should watch that the towing cable has been constantly tense.

On both cars external light devices according to «traffic Rules» should be included.

Ignition should be included so that the wheel was not blocked, and it was possible to include if necessary the index of turn, a sound signal, screen wipers and washer.

The amplifier of a drive of working brake system executes the function only at the working engine, therefore at the switched off engine it is necessary to press much more strongly at braking a brake pedal.

As at the idle engine the wheel amplifier does not function, at turns it is necessary to apply большее effort on a steering wheel.

In the absence of oil in АТ it is necessary to tow the car only with the hung out driving wheels.

Models with АТ and a full drive: towage of the car with the lifted forward or back wheels is not supposed.

Models with РКПП and a full drive: If the car is towed with the lifted forward or back wheels, speed of towage should not exceed 50 km/hour, and the towage distance should not exceed 50 km.

Models with automatic transmission

Key in the ignition switch turn in position 2.

Translate selector AT lever in position «N».

The maximum speed of towage: 50 km/h.

The maximum range of towage: 50 km.
Non-observance maximum or range of towage can lead to speed to transmission damage.

On the big distances or in case of damage of a transmission towage is supposed only with the hung out driving wheels.

At towage with the lifted forward bridge or the control of a lay brake at the stand for test of brakes the engine should be switched off. Otherwise, owing to activization of brakes electronic противозаносной damage of brakes of the back bridge will occur system (ESP).

Installation of a towing cable/bar

Forward towing eye

Take a towing eye from the complete set of the onboard tool, at the left in an aperture for a spare wheel.

Disconnect a cover (1). For this purpose press a thumb below, around a pad (2) and press fingers above a little, having released a cover (clips spring).

Screw an eye in a carving aperture against the stop by hand, then insert sideways into an eye a screw-driver or a wrench for a wheel and tighten an eye.

After towage end put an eye in the complete set of the onboard tool.

Connect a cover a pad (2) below, press it from above and thus fix it.

Back towing eye

Execution 1: Screw a back towing eye the same as a lobby.

Execution 2: the Towing eye is welded from below under a bumper.

Emergency start of the car by towage

On models with АТ - it is impossible.

For an exception of damages каталитического the converter it is not supposed to start the car at the warm engine by towage or pushing.

Preliminary try to start the engine by means of the storage battery of other car.

Models with АТ cannot be started by towage.

Models with the petrol engine can be towed for the purpose of engine start on distance no more than 50 m since otherwise there is a danger of damage каталитического the converter.

Before towage include 2 or 3 transfer, press and keep a coupling pedal.

Include ignition.

Slowly include coupling if both cars have started to move.

As soon as the engine was started, press a pedal of coupling and switch off transfer not to drive into pulling car.
