Hammers Interskol - failure and how to solve their own hands

Hammers Interskol, according to statistics, are reliable tools. Refusals recorded much less frequently, than in the more popular models Makita, Bosch, Hitachi.

The main rule: Choose a model, which is designed for a load and is designed to perform the planned works.

Using hammers as intended in accordance with the operating requirements of the punches can work for a long time Interskol.

But, like any tool, in rotary hammers there are various faults that require repair punch yourself, especially if he is no longer a guarantee.

To perform the repair hammers Interskol, troubleshoot, it is necessary to carefully examine the instrument device, his circuit, lubrication chart.
Any repairs perforator Interskol begins with his disassembling this in more detail.

Classification of faults in rotary hammers Interskol

Hammers Interskol have high maintainability, simplicity and reliability.

Repair hammers Interskol own hands able to perform any user, who knows how to keep the screwdriver, hammer and versed in electrical engineering at the high school level.

All manifest error in rotary hammers Interskol are divided into three groups:

  • Mechanical breakdowns impact mechanism;
  • Destruction mode switch;
  • Faults electrical perforator.

Mechanical faults in the group rotary hammers Interskol

Consider for example all the faults Interskol perforator P-26 / 800ER.

The first group consists of fault breakage, associated with the failure of the impact mechanism parts.

This fault is shown in the group, that when the hammer drill, and the batter can not.

Wear rubber sealing rings

The weakening of the force of the impact is gradual. As the wear of the rubber rings occurs air leakage in the pneumatic system, the creation of strike. Shot Power weakens, blow gets tough. In addition to loss of properties is the destruction pneumatic impactors, Boykov, pressmass.

  • Destroyed the piston skirt;
  • Break off the ears of the installation poz.48 finger.

Repair punch Interskol P-26 / 800ER and its destruction of the piston is performed by replacing the piston on the new. By purchasing the piston, carefully check the roughness of the inner surface of the piston. It should be brought to a mirror finish.

Failure of the key barrel. 36 not often seen. main reason, scratches on the inner surface at failure of strikers, Boykov, prommassy.

If the scratch depth is not great, the scratches can lead laps. At great depths of scratches ensure tightness impossible, and this affects the work of the punch in "Blow" mode.

The destruction of the roller bearing

Shock pulse is created not only the striking mechanism of the pneumatic system, but also the transformation of rotational motion into reciprocating through the work of the rolling bearing poz.60. There are cases of destruction of the bearing cage.

With the destruction of anti-friction bearing punch repair Interskol P-26 / 800ER is the complete parts replacement.

Report transmission torque in reciprocation may be interrupted due to the toothed wheel slippage splines in splined poz.62 combined rolling bearing poz.60.

The fault is eliminated correcting tooth profile using a round needle file.

Dropouts mode pin is shown at improper operation mode switch. Translation handles the mode dial does not move the leash poz.55 switch.

Breakage eliminated correcting assembly intermediate shaft pinion poz.58.

Rotation of gear in the trunk

Loss of drilling at the working stroke is manifested when turning on the shaft barrel gear poz.36 poz.35.

Gear fixed to the trunk of three rollers poz.37. And in order to securely hold, pinion presses spring poz.33, seating washer through poz.32 circlip poz.31.

Error occurs due to deterioration of strength of the pressure spring, loss rollers, the destruction of the sleeve cam poz.38.

Repair punch Interskol P-26 / 800ER their own hands is to restore all items in the desired position, or replacement of defective.

Faults countershaft

Intermediate shaft punch serves to transmit rotational and reciprocating impulse.

If any part, installed on the intermediate shaft, because of the damage can be turned, hammer drill stops.

Consider the principle of operation of the intermediate shaft Interskol perforator P-18 / 450ER.
