1 GENERAL SAFETY INSTRUCTIONS
1. During use, maintain control of the tool. The operators represent the most important
aspect of safety. To best protect against the risk of injury, work cautiously and carefully.
2. The pneumatic tool should not be used and repaired by someone under the influence of
drugs or alcohol.
3. When a fault / defect is detected, immediately disconnect the power supply cord from the
tool.
4. Only carry the pneumatic tool by its handle, and without pressing the start lever. Always
disconnect the compressed air supply hose before transport.
1.1 Risks Associated with the Work Area
1. Keep unqualified people, children, etc. away from the work environment and the pneumatic
tool.
2. Only use to tool with proper lighting and visibility.
3. Pay attention in unknown work environments and areas. The pneumatic tool is not isolated
from the power supply.
4. Be especially careful to avoid contact with dust, air jets or other pollutants. If necessary,
wear a dust mask.
5. It is important to maintain a stable and secure position while working. Beware of air hoses,
which can cause you to trip and fall.
1.2 Risks Associated with the Presence of Rotating and/or Moving
Parts
Hold the pneumatic tool correctly, using the handles.
Never touch the rotating parts of the tool, particularly the disc and disc holder shaft.
Vibration, repetitive motions and uncomfortable positions may be harmful to your arms and
hands. Discontinue use of the sander if you experience symptoms of physical discomfort,
tingling and pain.
While working, do not wear loose clothing or jewellery that could get caught in the moving
parts of the tool. Similarly, put hair back in a net or a cap.

4 COMMISSIONING
1. Remove the air inlet cap, then screw the nozzle into hole: 1/4" NPT Male Quick-Release
Coupling
2. Put a few drops of lubricating oil (without resin acid) in the air inlet nozzle.
3. Check the flexible air supply hose.
If it is damaged, broken, torn or deformed it must not be connected to the tool.
4. Check the state of the quick-release couplings (both on the tool and the hose). If signs of
damage are detected, it is broken or excessively corroded, the tool or the flexible hose
cannot be used.
5. The tool must be connected to the air supply source by means of an FRL air conditioning
unit, consisting of a filter, pressure regulator and lubricator, as shown in Figure 2.
The compressed air used must be clean and with the right mix of oil. Adjust the lubricator
in such a way that it applies 3 to 6 drops of oil per minute. Furthermore, the maximum
length of the hose between the lubricator and the tool must be a maximum of 6/8 meters.
Figure 2 – Connecting the air supply
6. Insert the quick coupling of the supply hose into the air inlet nozzle at the bottom of the
grinder.
7. Connect the suction tube of the vacuum to the suction inlet.
Air Pressure
To ensure proper operation and compliance with safety regulations, the operating pressure of
the compressed air must not exceed 6 bar (90 psi).
Higher pressures may cause damage and excessive wear of the tool.
Information on the working pressure is displayed on the tool's CE plate and in the
instructions.
Crushing and Cutting
When connecting the air supply hose to the tool, do not hold down the grinder's power lever
while attaching the quick coupling.

5 HOW TO USE
5.1 Attaching the abrasive tools (discs)
Crushing and Cutting
Before attaching and/or removing the discs, always remove the air supply hose.
Protective gloves
Before attaching and/or removing the discs, wear suitable protective gloves.
1. Select the disc with the desired size.
2. Tighten the disk lock firmly.
3. It is also possible to install discs with a "strap" on the pad already present on the machine.
Press the disc firmly to make it adhere completely to the pad.
5.2 Power On / Off
(Personal Protective Equipment) PPE
Before using the sander, wear suitable work clothing, gloves, shoes and
protective goggles. Also wear a mask if you work with materials that produce
dust or fumes. Also wear protective devices for the ears (hearing protectors),
such as earmuffs, earplugs, etc.
Workspace
Be familiar with the work area.
Always check the work area before using the sander.
Keep the work area clean, uncluttered and well lit.
Machining metals, such as magnesium, can lead to the formation of potentially explosive or
combustible dust or fumes; therefore, avoid the presence of flames or hot surfaces in the
work area.
After mounting the disc and connecting the flexible compressed air supply hose, hold the
sander by its handle.

The Sander is equipped with a knob for adjusting the rotation
speed of the disc according to the type of material and the type
of work to be performed: the harder the material, the greater
the speed of rotation.
Turn the speed adjustment lever of the disc to the desired
position:
Figure 3 – Speed
adjustment lever.
To start the sander, that is activate the rotation of the tool, press down with the palm of your
hand
The sander's start lever is a continuous hold lever, in the sense that the function controlled
(i.e., the rotation of the disc) is active as long as the lever itself continues to be pressed.
Therefore, release the lever to shut it down in an emergency.
Emergency
In case of an emergency, immediately release the sander's power lever.
Disconnect the air hose and turn off the tool in the event of the following:
to replace the discs;
to clean, rebuild or perform maintenance on the sander;
if the sander is not used for some time.

6 MAINTENANCE AND CLEANING
The purpose of this chapter is to provide all the information on maintenance procedures and
their frequency as required by the Sander.
INTERVENTION Frequency
Daily Weekly
1. General visual inspection X
2. General cleaning X
3. Clean the air outlet nozzle X
4. Lubricate moving parts X
1. General visual inspection: check the overall condition of the pneumatic tool,
particularly for any damaged or missing parts. Also check for the presence and legibility
of plates.
2. General cleaning: cleaning is necessary to rid the body of oil deposits, dust or dirt
accumulation.
Risks associated with cleaning
Disconnect the air supply hose and clean the body of the tool. Do not use organic solvents to
avoid corrosion or discolouration.
3. Cleaning the air outlet nozzle: cleaning is necessary to free the hot air outlet nozzle
and filter of dirt accumulation. Do not use paint thinner, gasoline, or similar substances to
clean the nozzle.
4. Lubricating moving parts: lubricate all the gears and
moving mechanical parts on the sander by inserting
lubricating oil inside the compressed air intake nozzle at least
once a day. To do this, disconnect the air hose, turn over the
sander and put a few drops of oil into the nozzle using an
suitable oiler (Figure 4).
Figure 4 – Lubricating
the nozzle.
