assembly perforator Hitachi DH24PS3 can realize anyone with the skills and knowledgeable locksmith common rules for working with electrical appliances.

Before assembling the gun, prepare a working place, a set of new rubber products, the necessary lubricants, tools, tester.

assembly punch is divided into several stages.

Assembling mechanical perforator Hitachi DH24PC3

Assembling the mechanical part begins with the assembly of hotel units included in the unit.

intermediate shaft assembly punch

intermediate shaft is part of the gun gear and performs two functions:

- transmits torque on the barrel the gun;

- converts torque in reciprocating impulse due to work drunk bearing.

The circuit assembly of the intermediate shaft

on the shaft fits poz.52 drunk poz.53 bearing, helical gear poz.54 large, metal ring and bearing poz.55 poz.56.

The perforator Hitachi DH24PC3 applied bearings made in Japan 626VVM type.Dimensions 6x19x6 bearing.You can replace the Russian analogue of the type 26.

Drunk bearing, helical gear, bearing smeared with grease.From domestic counterparts Nanohim recommended lubricant company, marked by a PM or by marking Nanotech Metallplak Electra.

On the other hand on the shaft fits poz.51 clutch, pressure spring poz.50, spur gear poz.49, the mode selector lever poz.48, metal sleeve poz.47.

in position 10 are inserted into the body:

- oil seal position 12;

- shock sleeve pos.13 mechanism;

- Felt seals pos.14;

- pressed bearing 6904DD poz.15;

- is inserted into the metal sleeve pos.16 restrictive;

- all fixed lock ring poz.17.

use the press or handmade wooden nastavku for pressing the bearing.

Pressing is performed using a press or a vise with a simple device.As devices using nastavku wood or soft material.

Assembly strikers

two types of strikers is used in the punch.

Components of the firing mechanism of the strikers

Components striker firing mechanism

poz.29 striker and striker item 37. Assembling the striker is equipped to them rubber sealing rings with grease mandatory.From domestic lubricants best lubricant Ciatim-224 in accordance with GOST 9433-80, inert to the rubber products.

On striker poz.29 except rubber sealing rings, worn shock mount mechanism poz.31, bush damper poz.35, retaining ring poz.36.Ring captures details on the striker.

On poz.37 striker.worn sealing rubber ring pos.38. The firing pin is lubricated with grease Ciatim-224 and is inserted into the sleeve poz.39 piston.

Assembling the piston sleeve

To assemble the piston sleeve, must be inserted in her ears piston pin poz.42, after inserting steel washers M30 poz.43.

When assembling the barrel when you insert it into the strikers, be sure to lubricate the inner surface of the piston.

entire assembly process is accompanied by the application of the grease types specified by the manufacturer or drills relevant domestic lubricants.


pen mode switch is connected to the mechanical part and the stator unit, you can proceed to install the handle of the mode switch.

Driving mode switch assembly of handles

Driving mode selector knob assembly

handle poz.21V mode dial is set below the housing.

to insert it into the housing and fix it, it is necessary to:

- insert the handle spring poz.19;

- insert fixing red button poz.18;

- wear rubber oil seal poz.20.

insert handle clockwise into the housing to "Strike", then turn it back to 15 degrees until it clicks.Handle locks.

Mechanical perforator Hitachi DH24PC3 collected.

Remember!When assembling the mechanical parts, observe the rules of the application of lubricants, use only those specified by the manufacturer or domestic, specially designed for rotary hammers.

Assembling electrical perforator Hitachi DH24PC3

divide the assembly of the electric punch into stages.

stator assembly

renovated or new stator poz.65 poz.68 installed in the stator housing and is secured by means of fixing screws M4 × 50 poz.64.Article stator 340635F.

remains to connect the mechanical unit and the stator housing.

When you insert the rotor into the stator housing, remove the pre-carbon brushes with the brush holder.

Assembling control circuits

control circuits is a circuit that allows to run smoothly punch, to adjust the frequency and speed.

Driving punch control circuits Hitachi DH24PC3

The perforator Hitachi DH23PC3 used coal electro poz.74, 77 with hitchhiking.Hitchhiking is not allows you to turn the punch, if the brushes are worn more than the permissible norm.

carbon brushes have to hitchhike article 999072, conventional brushes Article 999041. The carbon brushes in the brush holders are fixed casing perforator poz.75, article 955203.

Some modifications are applied poz.69 and a diode contact poz.72 choke.

The supply chain is included noise suppression capacitor poz.78.

The punch used pushbutton 220 (OLD 331454/324536).Article 335796. Switch Type TG801TSBU-1.

Details control circuits are mounted inside the handle of the stator housing.

Connect punch to AC power, check the operation in all modes.Make smooth adjustments, and the punch without fanfare.
