GENERAL SAFETY INSTR
UCTIONS
1.
During use, maintain control of the tool.
2.
The operators represent the most important aspect of safety. To better protect again
st
the risk of injury, work cautiously and carefully.
3.
The pneumatic tool should not be used and repaired by someone under the influence of
drugs or alcohol.
4.
When a fault / defect is detected, immediately disconnect the power supply cord from
the tool.
5.
Only
carry the pneumatic tool by its handle, and without pressing the "trigger" power
button. 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 envi
ronment and the
pneumatic tool.
2.
Only use to tool with proper lighting and visibility.
3.
Pay attention to 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
Grab
the pneumatic tool correctly, using the appropriate "gun" handle.
Never put your hands in front of the cutting edge of the chisel.
Vibration, repetitive motions and uncomfortable positions may be harmful to your arms and
hands. Discontinue use of the air
hammer 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.

COMMISSIONING
1.
Remove the air inlet cap, then screw the supplied 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
con
ditioning group, consisting of a filter, pressure regulator and lubricator, as shown in
Figure 4.
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. Furth
ermore, the
maximum length of the hose between the lubricator and the tool must be a maximum
of 6/8 meters.

6.
Insert the quick coupling of the supply hose into the
air inlet nozzle at the bottom of
the hammer.
Air Pressure
To ensure proper operation and compliance with safety regulations, the operating pressure of
the compressed air must not exceed 600 kPa (6 bar
s
).
Higher pressures may cause damage and excessive
wear of the tool.
Information for 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, while attaching the quick coupling, do not
hold down the air hamm
er's power "trigger."


Always make sure that the chisel is assembled correctly while trying to manually
remove it from the air hammer.

If it is not inserted all the way or the lock is incor
rectly tightened, the chisel may
release suddenly and may hit the operator or someone else
Inserting the Chisel
Always check that the chisel is compatible with the pneumatic tool.
Check that the chisel is in good condition, i.e. no cracks and not comp
letely worn out, before
operating.
Make sure that the tool is sharp before using it.
5.2
Power On / Off
(Personal Protective Equipment) PPE
Before using the air hammer, wear suitable work clothing, gloves, shoes and protective

f 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 air hammer.
A
lways make sure that there are no electrical cables, gas lines or waterlines installed beneath
the demolition area.
Keep the work area clean, uncluttered and well lit.
After assembling the tool and connecting the flexible compressed air supply hose, grab
the air
hammer by its "gun" handle.
The
Air Hammer
,

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 labe
ls.
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 dis
colouration.
3.
Clean 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.
Lubricate moving parts:
lubricate all the
moving mechanical parts on the air hammer
by inserting, at least once a day, lubricating oil within the compressed air intake
nozzle. To do this, disconnect the air hose, turn over the air hammer and put a few
drops of oil into the nozzle using a suitable
oiler (Figure 9).
