INSTALLING THE MILLING CUTTER
• There are several sizes of MACROZA milling cutter depending on desired width and
depth of the chase.
• Only original MACROZA milling cutters should be used as they are specifically
designed for MACROZA Wall Chasers.
• Make sure MACROZA Wall Chasers are switched off and unplugged from mains
power before handling the milling cutter.
• Install milling cutter as shown on Figure 1, with teeth facing downwards in cutting
position.
• Milling cutter shaft rotates to the left as indicated on arrow engraved on the milling
cutter cover (fig.1).
• Before installing the milling cutter it is very important to place a washer (supplied with
the machine and cutters) between the shaft and milling cutter. This will ensure perfect
seating on the shaft and will make it easier to remove the milling cutter after use.
It is also recommended to grease the thread shaft with oil or lubricant
• To remove milling cutter, use the special wrench as shown on Figure 2.
Fix the spanner between the shaft and milling cutter cover. Once the spanner is
attached hit the special wrench as shown in Figure 3. Do not hit the special wrench if
the spanner is not fixed between the shaft and milling cutter cover.
VERY IMPORTANT: Check the following each time before using MACROZA wall
chasers
• Milling cutter does not have any Tungsten Carbide plate missing.
• Ensure all milling cutter teeth are well sharpened.

VERTICAL CHASES
• Vertical chases are done from top to bottom.
• Right hand should hold on to handle and switch while the left hand firmly grips on the
milling cutter cover (Figure 5).
• Left hand guides the chaser machine bearing most of the force.
• Once the cutter has entered the wall, pull down MACROZA wall chaser with both
hands producing a straight vertical cut.
• A difference in movement from one hand to the other will produce a curved cut.
• Plug MACROZA wall chaser in the mains socket.
• Switch on the machine before contact with the surface to verify its rotating direction.
Teeth must rotate forward as shown in Figure 4.
• Lean your MACROZA wall chaser lateral to the wall. Slowly insert the milling cutter
into the wall (Figure 4).
• Hold the machine firmly to avoid initial vibrations.

MILLING CUTTER TUNGSTEN PLATE REPLACEMENT
eep your milling cutter sharpened at all times and without any missing Tungsten Carbide plate.
A milling cutter with a missing or broken Tungsten Carbide plate will be useless within a few hours
of work and may be a potential hazard. Repair immediately.
Tungsten Carbide plate replacement:
1. Use a blowtorch to remove all old plate remains.
2. Use a file to make the original gap. The gap should maintain the original position
3. New plate must welded with an autogenously filler weld. It should protrude 0.5 mm above the
milling cutter (figure 7).
4. Sharpen the new following instructions above.
MAINTAINING THE MACROZA CHASER MACHINE:
All repair & maintenance work on the machine must be carried out at a MACROZA Technical
Service Centre.
MACROZA Maintenance
We strongly recommend that all maintenance of Macroza Wall Chasers is done at an official
Macroza Technical Service Centre.
Regular maintenance should be done to ensure the best performance of your wall chaser.
DAILY MAINTENANCE
Check the milling cutter sharpeness approximately after each hour of use. Change milling cutter
when blunt.
After each day’s use, clean the machine to remove all traces of dust. If necessary, blow shots of
compressed air through the machine’s lots to remove dust.
MONTHLY MAINTENANCE
All MACROZA Wall Chasers used on daily basis should be checked at least once a month.
It is extremely important to check if there is play in the bearings located in the milling cutter shaft. At
the slightest play we strongly recommend that bearings are changed. Failure to do so may lead to
severe failures in the machine engine. Always change the pair of bearings.
In normal working conditions and due to the harsh nature of chasing job, it may be necessary to
change bearings each month.
Look through the lateral slots of the chaser to check whether there are sparks produced by the
carbon brushes in the commutator. If necessary replace both carbon brushes. Always replace the
pair of carbon brushes.
