1 GENERAL SAFETY INSTRUCTIONS
1. During use, maintain control of the tool.
2. The operators represent the most important aspect of safety. To best protect against
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.
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

Parts
1. Grab the pneumatic tool correctly, using the appropriate "gun" handle.
2. Never touch the rotating parts of the tool, particularly the spindle.
3. Vibration, repetitive motions and uncomfortable positions may be harmful to your arms
and hands. Discontinue use of the drill if you experience symptoms of physical
discomfort, tingling and pain.
4. 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.

2 DESCRIPTION OF THE DRILL AND INTENDED USE
The Reversible air drill(Art. 0339) is a portable pneumatic tool, to be used for drilling
holes in various kinds of material such as wood, metal, plastic, etc.
The drill is made up of the following parts (see Figure 1):
1) the typical "gun" shaped steel casing, which contains the vane rotor and the other
moving parts connected to the spindle shaft;
2) the spindle for mounting the bits on the drill;
3) the selector lever to set the spindle rotation direction;
4) the "trigger" switch to activate the spindle;
5) the compressed air inlet nozzle.

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 3.
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 3 – 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 Mounting the cutting bits
Crushing and Cutting
Before mounting and/or removing the cutting bits, always disconnect the air supply hose.
Protective gloves
Before attaching and/or removing the cutting bits, wear suitable protective gloves.
1. Insert a cutting bit (with a diameter between 1.5 mm and 10 mm) inside the spindle.
2. Close the spindle jaws by manually rotating the outer ring nut in a clockwise direction,
so that the bit is secured by the jaws themselves.
3. Insert the key into one of the circular slots on the spindle (Figure 4), then rotate
clockwise to tighten the spindle jaws. When finished, remove the key!

Centring of the bit
Always make sure that the bit is perfectly centred and aligned, before using the tool.

5.2 Power On / Off
(Personal Protective Equipment) PPE
Before using the drill, wear suitable work clothing, gloves, shoes and protective goggles.
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 drill.
Keep the work area clean, uncluttered and well lit.
Precautions for use
When drilling small or irregularly shaped objects, secure the work piece in a vice with soft
jaws.
After assembling the cutting bit and connecting the flexible compressed air supply hose, grab
the drill by its "gun" handle.
Position the selector lever to choose the spindle rotation direction (Ref. 3 in Figure 1) as
follows:
F(up) →Clockwise rotation (FORWARD)
R(down) →Anti-clockwise rotation (REVERSE)
To turn it on and begin the rotation of the spindle, press the button on the butterfly valve
(Ref. 4 in Figure 2).
The drill's start button is a continuous hold lever, in the sense that the controlled function
(i.e. the rotation of the spindle) is active as long as the lever itself continues to be pressed
down. Therefore, release the button to stop operation when finished drilling or in an
emergency.
Emergency
In the event of an emergency, immediately release the drill's power button.
Disconnect the air hose and turn off the tool in the following situations:
to change or replace the cutting tool;
to clean, rebuild or perform maintenance on the drill;
if the drill is not used for some time.

6 MAINTENANCE AND CLEANING
The purpose of this section is to provide all the information on maintenance procedures and
their frequency, as required by the Drill, Art. 0339.
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 5).

the nozzle.
