Wall Chasers MACROZA

More meters in less time

It is the fastest, reduces costs significantly. Compared to the traditional method of hammer and chisel, grinders and other machines from chases, the wall chasers MACROZA makes the work of opening chases in walls and partitions to embed electrical, water, heating, TV, air conditioning, etc. pipes exceptionally fast, easy and light. With MACROZA it takes only 15 seconds to open one meter of chase. The following table shows the production speed with MACROZA.

* These values are approximate, depending on the hardness and degree of abrasion of the material.

The best cost-benefit ratio

You will recover your investment in a very short time. Being able to make more than 500 m of chase in one day, calculate the time it takes to amortize the cost of the wall chaser. Thanks to the benefits offered by MACROZA, you recover the initial cost of the machine in a short period of time.

Does not break, does not shatter

Opens chases clean in a single pass. Have you calculated the cost of wreckage when doing the chases by hand or with a jackhammer? With MACROZA you can make chases clean and perfect in a single pass. Compared to conventional methods of opening chases, with MACROZA you can save up to 80% in time and materials.

More from wall chasers MACROZA

Hardly makes any dust

Granulates the material avoiding the production of dust. The MACROZA Wall Chasers produce hardly any dust. The low speed at which the milling cutter works means that it does not polish the material when cutting, as the diamond disc does, but simply granulates it. The debris produced accumulates on the disc cover and is then deposited on the floor. Therefore, it does not require a vacuum cleaner, as other machines do. All our models incorporate the option of attaching a vacuum cleaner if you need to work in indoor environments.

Attaches itself to the wall

The weight of the machine is not supported by the operator. The unique design of the MACROZA machine causes it to lean against the wall when cutting, thus taking up part of the weight of the machine. That is why we say that its weight is not important because it is supported by the wall itself. With MACROZA you can work longer with less effort. To work, just push the machine once it has been nailed to the wall.

The most powerful on the market

Works in materials where other Wall Chasers cannot. The MACROZA wall chasers have the most powerful engines on the market, which allows them to work in materials that other chasing machines cannot, such as cement block, solid bricks and concrete. With the MACROZA machine you will be able to work on:

• Gypsum wall
• Cellular concrete
• Cement plaster
• Hollow brick
• Solid brick
• Cement block
• Concrete

With MACROZA you can cut all types of material including stone and reinforced concrete.

Built to last

Low maintenance of the machine. Our more than 50 years of experience have resulted in a machine with simple yet very robust mechanics, ideal for the hard and rigorous work of opening chases. There are only 3 basic cares to be done to the machine:

• Clean the dust machinewith compressed air at least twice a week.
• Perform a general overhaul of the machine every 100 working hours, with emphasis on the brushes and bearings.
• If you work with milling cutters, always keep them sharp. Otherwise , you will not cut the material but will hit it, transmitting the blows to the machine and causing damage to bearings, pinions and motor.

Increased safety

Exclusive design to avoid accidents. The unique design of the machine protects the operator from the cut-off wheel, unlike other machines such as radials. The disc cover encloses the disc to prevent accidents. The wall chasers MACROZA has double electrical insulation and complies with all electrical safety regulations.

Open all types of chases

It hardly leaves any finishing touches in the corners. The MACROZA Wall Chasers can open vertical, horizontal, oblique and close to the ground chases. The milling chasers also allow to make all kinds of curved chases, unlike the other machines on the market. It leaves only 1 cm of overhang in corners and ceilings thanks to the position of the discs located on one side of the machine, unlike other milling cutter disc machines.

Vacuuming of dust and debris

Dust and debris collection option. All our models can be connected to a vacuum cleaner if the job requires it. To do this we screw an aluminum tube into the cap of the Milling cutter, which is in turn connected to the vacuum cleaner. This is highly recommended for working in indoor or living spaces, or work environments that require minimizing dust and debris production as much as possible. If it is not necessary to use the vacuum cleaner, a protective cap, also made of aluminum, is screwed in place of the aluminum tube.

It is essential that the machine is properly gripped, as this is essential for the proper performance of the work. To do this we must follow the instructions in the instruction manual.

The photos below show the correct way to hold the machine.

To start the work, operate the switch with the discs rotating in the air to check the direction of rotation and positioning of the discs.

the discs should move forward. Lean the machine sideways on the wall and, swinging, insert the discs little by little into the wall. Hold the machine firmly to avoid initial vibrations.

The vertical chases are made from top to bottom. The right hand will be on the switch handle and the left hand on the disc housing.

The left hand is the guiding hand and the main effort. Once the discs are inserted into the wall, by pulling the machine with both hands at the same time, it will produce a straight channel.

It is very important that the machine is properly gripped. Guides on each side of the disc cover will indicate the cutting direction.

To open chases obliquely we will follow a process similar to that for opening vertical chases.

The horizontal chases are made from right to left. The right hand will grasp the machine by the right side of the disc housing handle and push to the left.

The right arm will rest on the machine and push it from the bottom also to the left. The left hand will embrace the switch handle acting on it.

The following pictures show how to place the hands. It is very important that the machine is properly gripped.

MACROZA’s M90 and SC300PRO milling cutters are the only ones on the market capable of making curved chases. To do so, we will start from the traditional chases opening described above.

When performing chases both vertically and horizontally, a difference in displacement between one hand and the other rotates the machine, producing a curved chase.

The following photographs show the different postures that the hands must adopt in the successive opening phases of a curved chase.

The horizontal chases near the ground are made from left to right.

The right hand will grasp the machine by the rear handle and the left hand will grasp the left side of the disc housing handle and push to the right.

Thanks to the unique design of the machine MACROZA, the user will be able to work in places that are more difficult to access.

In the following photos we can see how chases is made close to the ground. It is very important that the machine is properly gripped.

It is possible to make wider chases. To do this, we will make two parallel cuts side by side, obtaining twice the width.

It is also possible to build manhole and switch boxes. To do this we will first make a cut on each of the sides where the register box will go. Then remove the remaining center by moving the machine from one side to the other until it is emptied.

In the following pictures we see the correct position of the hands.

We recommend that all maintenance work be carried out by a specialist at an Official Service Center MACROZA.

Always use original spare and replacement parts MACROZA to avoid risks to the user’s safety.

DAILY

If your wall chaser has a milling cutter

Check the state of sharpness of the teeth of the milling cutters approximately every hour of work. To do this, use the sharpness tester MACROZA. Replace or sharpen the milling cutter when it becomes dull.

The sharpening of the milling cutter will be done dry using the Sharpening kit MACROZA , specially designed for our milling cutters. Alternatively, a grinder with a silicon carbide 80 grit, Grade JK grinding stone may be used.

Machine cleaning

At the end of each working day, it is important to check the condition of the brushes and clean the machine of dust by blowing pressurized air through the grids if necessary.

PERIODICALLY

All wall chaser used professionally on a daily basis should be checked at least once a month.

Bearings

Check the clearance in the Milling cutter shaft bearings. At the slightest oscillation we recommend its replacement, otherwise it will cause serious damage to the mechanics of wall chaser.

Under normal conditions and due to the hardness of the work performed, it may be necessary to replace the bearings every month.

Brushes

Check through the side slots if the sparks produced by the brushes in the collector are higher than normal. Check their condition. If necessary, replace them. Never change only one wiper blade, always replace both at the same time.

It is not advisable to use up the brushes.
