To remove the mode switch, you first need to switch it to the "impact with drilling" mode, and then dismantle it. To do this, you need to press the switch to the housing and move it slightly below the impact with drilling mode, then pull it towards you.

Following the switch, you can remove the plastic cover of the housing, under which the gearbox is located, or remove the mechanism from the base of the housing.It all depends on the model of the hammer drill that is being repaired. After repairing the gearbox on the hammer drill, you will need to assemble it back in place, having previously treated it with lubricants. There should be enough lubricant to eliminate the possibility of the mechanism operating in conditions without lubricants.

Disassembling a hammer drill does not present any difficulties, but canada telegram data the dismantling process differs depending on the type of tool. For example, repairing a barrel hammer drill begins with draining the oil from a special container, while pistol devices do not have such devices.

The process of disassembling a barrel drill begins with removing the plastic cover located on top.To access the electrical part, you will need to remove the plastic cover at the bottom. The principle of repairing the electrical and mechanical parts of a barrel-type hammer drill is similar to straight devices.

On barrel drills, crank-connecting rod mechanisms are used instead of skew bearings. However, in the design of such units, sliding bearings are used, located on the wheel cam together with the eccentric. All these mechanisms operate in liquid lubrication, the amount of which must be sufficient. If there is not enough lubrication or it has not been changed for a long time, the probability of failure of the crank-connecting rod mechanism of the drill increases.
