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.

The tool is operated by means of a lever which opens the air valve and thus ensures the supply of compressed air to the tool drive.

If the lever is equipped with a lock that prevents the lever from being accidentally pressed. Turn the lock, so that it is parallel to

the lever, and then pull the lever towards the tool housing. This will start the tool. Allow the tool to reach its rated speed and only

then start working.

The tool stops when the pressure on the lever is released. The lever automatically returns to the rest position and the lock secures

the lever. Please note that the inserted tool can still move for some time after. Do not put the tool away until the inserted tool has

come to a complete standstill.

Drilling

Adjust the pressure in the pneumatic system so that it does not exceed the maximum value for the tool.

Fit a suitable drill bit in the holder.

Connect the drill to pneumatic system .

Press the switch and check that the drill / bit does not show excessive axial run out. If necessary, disconnect the drill from the

source of compressed air power, then replace the drill /bit with a new one.

Insert an appropriate drill bitt to the area designated for the opening.

Gradually press the trigger of the tool.

To make it easier to take the drill bit out of the hole, release the pressure on the switch, wait for the drill bit to come to a complete

stop. Change the direction of rotation to opposite and tap the trigger gently. Take the drill bit out of the hole carefully.

After ﬁ nished work, dismantle the pneumatic system and preserve the tool.

MAINTENANCE

Never use gasoline, solvent or other ﬂ ammable liquid to clean the tool. The vapours can be ignited, may result the tool explosion

and serious injury.

Solvents, used to clean the tool holder and the body, can result softening of seals. Thoroughly dry out the tool before starting

your work.

In case of any irregularities in the tool operation, the tool should be immediately disconnected from the pneumatic system. All the

components of the pneumatic system must be protected against contamination. Any contamination which enters the pneumatic

system can damage the tool and other components of the pneumatic system.

Tool maintenance before each use.

Disconnect the tool from the pneumatic system.

Before each use, let a few drops of preservative ﬂ uid WD-40 through the air inlet.

Connect the tool to the pneumatic system and run for about 30 seconds. It will allow to distribute the preservative ﬂ uid inside the

tool and clean it.

Disconnect the tool from the pneumatic system again.

Let a few drops of oil with viscosity SAE 10 inside the tool, through the air inlet and special designed openings for this purpose.

It's recommended to use oil SAE 10 intended for maintenance of pneumatic tools. Connect the tool and run it for the short time.

Note! WD-40 may not be used as an appropriate lubricating oil.

Wipe away excess oil, which has leaked out through the outlets. The oil, which has been leave may damage the tool seals.

Other maintenance operations

Before each use of the tool, check that no signs of damage are visible on the tool. Tool drivers, holders and the spindles must be

kept clean.

Every 6 months or after 100 hours of operation, it's necessary to hand over the tool for reviewing by the qualiﬁ ed personnel in

the repair workshop. If the tool was used without the use of a recommended air supply system, it's necessary to increase the

frequency for reviewing of the tool.
