Additional safety instructions for pneumatic tool
Air under pressure may cause serious injuries:
- always cut off the air supply, drain hose of air pressure and disconnect the tool from the air supply, when: it is not used, before
the exchange of accessories or before the repairs;
- you should never direct air stream towards yourself or anyone else.
A stroke by the hose can cause serious injuries. You should always check for damaged or loose hoses and couplings. Cold air
should be directed out of the hands. Every time when the universal screwed connections are used (claw connection) you should
use protective mandrels and connectors, which are protecting against possible damage of connections between hoses and be-
tween the hose and tool. Do not exceed the maximum air pressure required for the tool.
Never transport the tool by holding its hose.

OPERATING CONDITIONS

Make sure that the compressed air source can generate appropriate working pressure and that it ensures the required air fl ow. In
the case of excessive air pressure supply you should use reducer with safety valve. Pneumatic tool should be fed by the system of
fi lter and lubricator. It will provide, at the same time, purity and air lubrication by oil. Status of fi lter and lubricator should be checked
before each use and possibly clear the fi lter or complement defi ciency of oil in the lubricator. This will ensure proper exploitation
tool and will extend its life span. Do not use tools and grinding wheels, which are designed for cutting.
Do not use grinding wheels other than those, which are indicated in the technical specifi cations.
Make sure that the maximum rotational speed of the disc is higher than the speed of the grinder.
Semi-mounted sanding disks should be placed concentrically on the pillow.
Wear safety goggles during the work, it is also recommended to use gloves and protective clothing.
During some operations may arise poisonous or combustible dusts and fumes. Work in a well ventilated area and use personal
protection equipment.
TOOL USE
Before each use of the tool, make sure that no parts of the pneumatic system are damaged. If you notice damage, immediately
replace the components with new, undamaged ones.
Dry condensed moisture inside the tool, compressor and hose before each use of the pneumatic system.
Preparing the tool for operation
Screw a suitable nozzle to the air inlet thread fi rmly and securely to connect the air supply hose (II).
Before installing the blade, make sure that the permissible rotation speed of the blade is equal to or higher than that of the grinder.
Mount the blade with the dimensions specifi ed in the technical data table on the spindle. Tighten the blade by hand (IV) while
holding the spindle with a wrench. Make sure that the wrench is removed from the tool after the blade has been mounted. If the
wrench is left in the tool, it will turn into a projectile after it has been started, and this can cause serious injury.
Manually rotate the blade (several revolutions) to ensure that the blade rotates smoothly and without jams.
Attach a disc of abrasive paper or cloth to the underside of the blade. The surface of the disc to be clamped shall be covered with
a special non-woven fabric to allow the disc to be held in place by the blade velcro. The disc should have the same diameter as the
blade, it should be attached concentrically. The edge of the disc must not project beyond the edge of the blade. It is recommended
to use discs without holes for the extraction of dust generated during work. The grinder blade is not equipped with holes and will
wear out more quickly if you use a hole disc.
Adjust the air outlet of the tool so that the outgoing air stream is not directed towards the operator (V).
The tool is ready to be connected to a pneumatic system.
Connecting the tool to the pneumatic system
The fi gure shows the recommended manner of connecting the tool to the pneumatic system. This will ensure the most effi cient
use of the tool and also prolong the tool's service life.
Apply a few drops of SAE 10 viscous oil into the air inlet.
If the tool is equipped with a rotation reversing switch, set the correct direction of rotation.
Wherever possible, adjust the pressure (torque).
Connect the tool to the pneumatic system using a hose with an internal diameter of 10 mm / 3/8". Make sure the hose has a
durability of at least 1.38 MPa. (V)
Make sure that the inserted tool is not in contact with any object, then run the tool for a few seconds to make sure that no suspi-
cious sounds or vibrations are coming from the tool.
Starting and stopping the tool
Caution! Before starting the pneumatic tool, make sure that the mounted inserted tool does not come into contact with any object
or any body part.
