PERFORMANCE ORDER

1. Disconnect a wire from the negative plug of the storage battery. 2. Disconnect high-voltage wires. 3. Compressed air clear candles that will exclude dirt hit in cylinders of the engine after вывинчивания spark plugs. 4. Turn out a candle, using a candle key. For an exception of damage of a candle establish a candle key strictly along a candle axis.

PERFORMANCE ORDER

1. Connect a wire to the negative plug of the storage battery. 2. Connect a spark plug to a high-voltage wire. 3. Keeping a spark plug special пассатижами with the isolated handles, bring a spark plug on distance of 5-10 mm to a car body. The prevention Do not concern bodies of the car during performance of following operations. 4. The assistant should turn a cranked shaft of the engine a starter, thus between a spark plug and a car body should be observed steady strong искрообразование. 5. In the absence of a spark of ignition or an ignition spark weak, check up a condition and correct following defects:     – In the presence of a deposit clear or replace a spark plug;     – At pollution by oil clear or replace a spark plug;     – At deterioration or burning out of electrodes replace a spark plug;     – At destruction of a ceramic insulator replace a spark plug;     – At damage of a ring of a spark plug replace a spark plug;     – At infringement of an interelectrode backlash in a spark plug, adjust a backlash. Backlash updating is carried out подгибанием a lateral electrode. The central electrode in no event cannot be bent, as it can lead to breakage of an insulator and a candle exit out of operation. For подгибания a lateral electrode of a candle it is necessary to use the special tool. Interelectrode backlash of a spark plug: А3Е: 0,8–0,9 mm А5D: 0,7–0,8 mm
