Operating Conditions; Use Of The Tool - YATO YT-09740 Manual Original

GB
experience numbness, tingling, pain, or skin whitening in the fingers and hands, you should stop the use of pneumatic tool and
then inform the employer and consult a doctor. Service and maintain the pneumatic tool according to instructions will allow to avoid
unnecessary increase in the level of vibration. Keep the tool lightly, but securely, taking into account the required reaction forces,
because the threat from vibration is generally larger, when the grip force is stronger.
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 flow. In
the case of excessive air pressure supply you should use reducer with safety valve. Pneumatic tool should be fed by the system of
filter and lubricator. It will provide, at the same time, purity and air lubrication by oil. Status of filter and lubricator should be checked
before each use and possibly clear the filter or complement deficiency 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 specifications.
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.

USE OF THE TOOL

Before each use the tool to make sure that no part of the pneumatic system is not damaged. In the case of observed damage, that
part should be immediately replaced by new undamaged system component.
Before each use of the pneumatic system it should be dried from the moisture condensed inside tool, compressor and pipes.
Connection of the tool to pneumatic system
The figure shows the recommended method to connect the pneumatic tool. The presented method will ensure the most efficient
use of tool and also will extend the lifespan of tool.
Let a few drops of oil with a viscosity SAE 10 to the air inlet.
To the air intake thread tightly and firmly screw the proper ending, which will allow to connect the hose of air supply (ii).
On tool driver you should mount the adequate tip. For work with pneumatic tool you should use only equipment designed for work
with the percussive tools.
Adjust the proper direction of revs. Clockwise revs are marked by the F letter, counterclockwise revs are marked by the letter R.
Where possible, adjust the pressure (revs). Clockwise turn of the regulator reduces pressure, and rotation in the opposite direction
increases it.
Connect the tool to pneumatic system using a hose of inner diameter 10 mm / 3/8 ". Make sure that the hose resilience is at least
1,38 Mpa (iii).
Start the tool for few seconds making sure that it does not produce any suspicious noises or vibrations.
Assembly and exchange of the equipment (iv)
Make sure that the maximum speed of the equipment is higher than the speed of the grinder.
Lock the spindle with key.
Holding the spindle, firmly tighten the wheel to spindle.
Grinder is equipped with a shield with Velcro to allow installation of various overlays, such as sandpaper. Sandpaper should be
placed concentrically. It is recommended to attach to disc the sanding sheet with holes cut out so that the holes in the disc match
the holes in shield. This will increase the efficiency of removal of dust created during operation.
Attention! Before attachment of the overlay you should check it for a damage, it is forbidden to use damaged overlays. This creates
a risk of injury during operation.
