Set the right direction of rotation. The
Install the additional holder, insert the bracket through the drill body and tighten screw the holder. Fit the holder in a position that
will provide safe and ergonomic work. (V)
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

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.
Troubleshooting
It's necessary to stop using the tool immediately, if the tool is found to be defective. Using a defective tool can cause injury. All
repairs or replacements of the tool components should be carried out by qualifi ed personnel at an authorized repair workshop.
