“PORTABLE ELECTRICAL CHASER MACHINE”

The term “power tool”, “machine”, and “chaser machine” in all warnings below refers to mains-
operated MACROZA SC-100 wall chaser.
1. Keep your work area clean, tidy and well lit. Dirty, untidy and dark work areas increase the
risk of accidents.
2. Do not operate MACROZA SC-100 in explosive atmospheres such as in the presence of
flammable liquids or gasses. Power tools create sparks which may ignite fumes.
3. Do not expose MACROZA SC-100 to rain or wet conditions. Contact with water when using
a power tool will increase the risk of electric shock.
4. Keep bystanders, children and visitors away while operating MACROZA SC-100.
5. Tools with an earth or ground connection to the exposed metal parts must be connected to
a power outlet that has an earth or ground connection in accordance with all codes and
regulations. Check with a qualified electrician if you are in doubt as to whether the outlet is
properly earthed or grounded.
6. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
7. Do not abuse the cord. Never use the cord to carry the MACROZA SC-100 or pull the plug
from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged
cord immediately. Damaged cords increase the risk of electric shock.
8. When operating MACROZA SC-100 use only outdoor extensions cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce the risk of electric shock.
9. Stay alert; watch what you are doing when operating MACROZA SC-100. Use common
sense. Do not use the power tool when tired or under the influence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in serious personal
injury. To reduce the risk of fatigue it is recommended to have a break of no less than 10
minutes after every hour of work
10. Use safety equipment. Always wear eye and ear protection and rubber gloves. Safety
equipment such as dust mask, non-slip footwear or hard hat used for appropriate conditions
will reduce personal injuries.
11. Dress properly. Do not wear loose-fitting clothing or jewellery. ong hair should be tied
back. Keep your hair, clothing and gloves away from moving parts as they can be caught in the
power tool.
WARNING! Read and understand all instructions before using the MACROZA SC-100. Failure
to follow all basic safety measures listed below may result in electric shock, fire and/or serious
personal injury.

12. Do not overreach. Keep a proper footing balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations. Follow instructions in this book of
proper chasing positions.
13. Store idle MACROZA SC-100 in a dry safe place under lock and key and out of reach of
children. Do not allow persons unfamiliar with the chaser machine or these instructions to
operate the power tool. Tools are dangerous in the hands of untrained users.
14. Avoid accidental starting. Make sure the switch is off before plugging in. Do not carry
MACROZA SC-100 with your finger on the switch. In case an unexpected jam occurs, switch
the power tool off and unplug it from the mains socket.
15. Remove adjusting tools and attachments before turning MACROZA SC-100 on. A wrench
or a key that is left attached to a rotating part of the machine may result in personal injury.
16. Disconnect the plug from the power source before making any adjustments, changing
accessories or storing the MACROZA SC-100. Such preventive safety procedures will reduce the
risk of starting the machine accidentally.
17. Do not overload the MACROZA SC-100 as it will work more safely and efficiently within
the indicated power range. Do not use this wall chaser on extremely hard materials such as
concrete or stone.
18. Do not force the tool. Use the correct tool for your application. The correct tool will do the
job better and safer for which it is designed.
19. Do not use MACROZA SC-100 if the switch does not turn on and off. It must be repaired
immediately.
20. Maintain MACROZA SC-100 with care. Keep power tool clean and milling cutter sharp to
ensure perfect working condition.
21. All moving parts should be periodically inspected together with the cord and cutter
protective cover.
22. Keep handles clean and free from grease and oil. Properly maintained tools reduce risk of
personal injury.
23. Warning! Use only MACROZA original parts. Failure to do so may lead to personal injuries.
24. Before starting the job, check for damages or breakages and any other condition that may
affect the operation of the wall chaser or moving parts. If damaged, service the MACROZA SC-
100 before using it. Many accidents can be caused by poorly maintained tools.
25. Always use approved MACROZA service centres for maintenance. Have power tool service
by a qualified repair person. This will ensure safety of the machine is maintained.
26. MACROZA SC-100 is designed in accordance with these instructions and in the manner
intended for the particular type of job. All maintenance should carry out by a specialist and
using only MACROZA original spare parts.
27. The MACROZA SC100 chaser machine should not be used to perform work for which it has
not been designed (for example, to cut wood). Use of chaser machine for operations different
from those intended could result in a hazardous situation.

The MACROZA SC100 chaser machine’s cutting attachment is a widia-tipped (Carbide
Tungsten) milling cutter.
It is used with seven different types of milling cutters depending on the measure of chase
required (depth x width):
NOTES:
Cut width and depth might vary depending on milling cutter’s level of wear.
• For cuts wider than 50 mm, make two parallel cuts side by side
• For gear or switch boxes, make two additional parallel cuts on each side of the existing cut.

INSTALLING THE MILLING CUTTER
• There are several sizes of MACROZA milling cutter depending on the width and depth of the
chase.
• Only original MACROZA milling cutters should be used as they are designed specifically for
the MACROZA SC-100.
• Make sure that the MACROZA SC-100 is switched off and unplugged from mains power
before handling the milling cutter.
• Install milling cutter as shown in 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 (Figure1).
• 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 make it easier to remove
the milling cutter after use.
• 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 it is
not fixed between the shaft and milling cutter cover.
VERY IMPORTANT: Check the following each time before using MACROZA SC-100
• Milling cutter does not have any widia (Carbide Tungsten) tip missing.
• Ensure all milling cutter teeth are sharpened.

REPAIRING THE MILLING CUTTER (plate replacement):
Keep your milling cutter sharpened at all times and without any missing carbide widia tooth.
A milling cutter with a missing or broken widia tooth will be useless within a few hours of work
and may be a potential hazard. Repair immediately.
Widia tooth replacement:
1. Use a blowtorch to remove all old widia tooth 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 widia tooth following instructions above.
MAINTAINING THE MACROZA CHASER MACHINE:
All maintenance and repair jobs on the machine must be carried out at a MACROZA Technical
Service Centre.
MACROZA Wall Chaser 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 sharpness of the milling cutter approximately after each hour of use and change the
cutter when it becomes blunt.
After each day’s use, clean the machine so that there is no dust. If necessary, blow shots of
compressed air through the machine to remove the 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 any play in the bearings located in the milling
cutter shaft. At the slightest play we strongly recommend that the bearings are changed.
Failure to do so may lead to severe failures in the machine engine.
In normal working conditions and due to the harsh nature of chasing job, it may be necessary
to change the bearings each month.
ook through the lateral slots of the chaser to check whether sparks produced by the carbon
brushes in the commutator are stronger than normal. If necessary replace both carbon
brushes. Always replace the pair of carbon brushes.
AFTER-SALES SERVICE FOR YOUR MACROZA SC100:
MACROZA has an Official Technical Service Centre network to provide you with excellent service
and fast repairs.
The use of non original MACROZA spare parts could lead to machine damage.
