Description of Metabo wall chasers

The article provides a brief description of Metabo chasers and individual models of furrow cutters. Discs for concrete chasers and casings are described. Advice on operation is given.

From the outset, it should be emphasized that Metabo wall chasers can be considered quite a worthy tool. They are reliable and work well even in rather difficult conditions. This technique is capable of cutting through even hard materials very quickly and with minimal difficulty. The cutting depth is very large.

The characteristic features of the Metabo technique:

• soft start option;

• the ability to fix the spindle;

• prevention of repeated launches;

• disconnection of drives when blocking equipment;

• minimum load on the musculoskeletal system;

• long service life of the equipment.

When choosing a decent furrower, it makes sense to pay attention to the MFE 40 model with an internal index 604040510.

This device is different:

• sturdy body, obtained by aluminum casting;

• a cut designed for optimal visibility;

• the ability to maintain stable speed under heavy load;

• LED indication of excessively powerful load and blocking during abnormal operation;

• automatic safety clutch for increased safety of use;

• the ability to cut grooves up to 3 cm in one run.

The model with the same name, but with the index 604040500, costs a little more. The weight of such a chaser is 8 kg 980 g. The milling depth reaches 4 cm. Reliable protection against dust penetration is provided.

Technical properties:

• idling up to 5000 rpm;

• section of the cutting wheel up to 12.5 cm;

• torsion at rated load at a speed of up to 4200 revolutions;

• torque intensity 6 Nm;

• rated electrical consumption 1.92 kW;

• power during operation (output) 1.12 kW;

• weight excluding mains cable 4 kg 600 g.

For concrete, the more professional MFE 65 can also be used. It weighs 18.8 kg, but this weight is fully justified by the capabilities of the product. The groove width can be flexibly adjusted as required. Prevention of unintentional starts is provided. Thanks to the locking spindle, the replacement of the working discs is greatly facilitated.

Technical specifications:

• total power 2.4 kW;

• 2 main disks;

• the possibility of a cut 2-6.5 cm in depth;

• groove width from 0.3 to 4.1 cm (with several intermediate steps);

• the landing section of the disk is 2.22 cm.

This list includes more than just discs and shrouds, as is often believed.

For furrowers, the following may also come in handy:

• tension flanges;

• rubber bushings for anchors;

• washers;

• brush holders;

• start buttons;

• ventilation discs;

• half-countersunk screws;

• cable insulators;

• keys;

• lubricants;

• adjusting nuts;

• thermal sensors;

• indicators;

• handles;

• cross-shaped handles;

• adapters;

• traction;

• clamps;

• friction discs;

• bolts;

• covers;

• spindles and some other parts.

Even the best Metabo equipment, complete with good equipment, must be used carefully and thoughtfully. Appropriate personal protective equipment must of course be used. Diamond blades are better than others because they work more efficiently and wear less.

Correct gating means making accurate measurements. The depth of the groove for the cable must also take into account the amount of insulation (outer sheath), which must also be hidden. You need to hold the wall chaser strictly with both hands. They need to move slowly; disc braking should occur by itself, and it is most correct to wait until it is completed, without trying to force this process. The motor should be periodically purged, and the replacement of brushes is always entrusted to professionals working in a prepared workshop - you cannot change them with your own hands.
