For long work perforator Bosch necessary any regular and timely maintenance, the use of quality lubricants, timely replacement of carbon brushes, rubber products.Condition monitoring of bearings and wear.Getting repairs perforator Bosch with his hands, it is recommended to apply the lubricant, which advises the manufacturer.

How to extend the performance of the gun Bosch

Hammers Bosch require mandatory inspection and maintenance.To prope

rly operate the drills, it is necessary to:

  • to prevent dust from entering the cooling holes (you can wear a nylon stocking or use a vacuum cleaner);
  • lubricate the shank drills with special grease;
  • not overheat power (when overheated lubricant crystallizes and stops lubricate moving parts);
  • intensive work to replace the rear rotor bearing every 6 months;
    through 70 hours to change the carbon brush;
  • for drilling holes in the ceiling to turn the hammer down and scroll in such a position for the flow of lubricant to the place;
  • after work is required to purge the inside of the gun with compressed air;
  • often change the rubber sleeve on the chuck punch;
  • avoid the appearance of sparking brushes on the collector in an idle mode;
  • duration of continuous operation should not exceed the 30-minute interval;
  • not use the "Blow" mode often.

Being accepted for the repair of the gun Bosch 2-20, 2-24, 2-26, see the map indicating the lubrication points grease and lubricants.

Hammers Bosch Lubrication

Lubrication perforator Bosch

Bosch rotary hammers for lubrication used several types of lubricants, depending on the operating conditions for units and parts.

  • 1615430001- lubrication for gearbox and its cavity;:

    four types of lubricants used in the Bosch rotary hammers

  • 1615430002- lubricant for gears, idler bearings, clutch;
  • lubrication 1615430020 - bearing (FT1V26);
  • grease SAE 20 W - for rubber products.

Lubricants vary in viscosity and consistency.

From Russian lubricants may be recommended lubrication under sonorous name "BisonĀ»:

Assembling the gun Bosch 2-26

assembly punch is recommended to perform under the scheme, such as the Bosch rotary hammer 2-26.The presence of the assembly scheme simplifies the process, tells the sequence of assembly of parts and components.

Assembling other rotary hammers Bosch is the same, although some design features in rotary hammers Bosch 2-20, 2-24, 2-26 are available.

Assembling electrical perforator Bosch 2-26

assembly power tools, including hammer drill Bosch 2-26, should be performed on a pre-prepared site.
Prepare workplace, lay a table or a clean paper towel.Prepare the tools required for the job.Of the tools you will need: a screwdriver, pliers, tester, the hammer 100 g, spacers of soft metal.Spacers come in handy when installing bearings on the rotor shaft and the intermediate perforator Bosch, for their heads.

Before assembling mechanical parts, check for new rubber sealing ring, the integrity of all components, the presence of lubricants according to the lubrication map above.

collected mode selector knob poz.832 mode dial is set to the gun body so that the red pen button was directed parallel to the handle of the gun.

handle is rotated in a clockwise direction to the position of "drilling".There will be a click.The handle is inserted into the gun.

sure to check the operation mode switch, turning it to the desired position and including a punch in each mode.

quick assembly of the cartridge

The Bosch rotary hammers used chuck SDS-plus models.

they are structurally different device working bodies of the clip.

assembly punch cartridges produce renovated cartridge replacement destroyed part.

cartridge assembly before it is mandatory to check the locking balls.They must be corrosion, and their diameter must not vary by more than the nominal 0.01 mm.

quick chuck assembly sequence repeatedly described on our website.

The build quality of the quick chuck is determined by its capacity for work.Insert the cartridge in the gun of any tool with a corresponding shank.Hold the hand on the body of the drill, try to get him out of the weight of the cartridge.If you do not manage to do, the job holder is considered to be reliable.

That's all.Hammer Bosch 2-26 assembled.Build models of drills Bosch 2-20, 2-24 is almost the same except for small details that do not affect the assembly process.
