Before using the tool, check the operational area, freeing if of objects that could cause
obstruction and ensuring that there are not electric cables or pipes walled in or under the part
to be drilled or demolished.
Prepare a sort of “working plan”, trying to foresee and avoid unexpected events, damage or,
worse, accidents.
1 - Connect the tool to the hydraulic hoses of the power pack (or other hydraulic source).
The pressure hose enters the hole in the tool at “IN” , is the port corresponding of the upper
hole where on the short hose is installed a female quick coupler .
2 - The discharging/ return hose ( Tank) comes out of the tool from the tube at the hole market
“OUT”, is the port corresponding of the lower hole where on the short hose is installed a male
quick coupler .
IF THE HOSES OF THE POWER PACK ARE LEFT IN THE SUNLIGHT FOR A LONG TIME, THE
EXPANSION OF THE OIL DUE TO THE HEAT COULD OBSTACLE THE PREVIOUS OPERATION.
WHENEVER POSSIBLE, CONNECT THE ENDS OF THE HOSES TO ONE ANOTHER.
3 - Choose the SDS MAX bits of the appropriate diameter
4 - Check the wear of the bits. If the bits in Widia or Tungsten are damaged or missing, even
the best drill will give poor performance.
STARTING ON /OFF
To start the tool, simply pull the trigger. To stop it, release the trigger. The number of
revolutions of the bit can be changed according to the pressure exercised on the trigger. Tthis
characteristic facilitates the initial approach when drilling hard materials.
DRILLING
Place the bit where the hole is to be made and pull the trigger. Do not force the tool. Light
pressure gives best results. Keep the drill in place and prevent it from slipping out of the hole.
If the holes become blocked by splinters or particles, instead of forcing the tool, let it idle then
pull the bit out of the hole, removing the rubble. By repeating this operation several times, the
hole will be completely cleaned and bits will rotate freely.
END OF OPERATIONS
1. LAY DOWN TOOL, TRY LIMITING CONTACTS WITH THE MUD AND DIRT
2. PUT THE FLOW LEVER OF THE POWER PACK IN OFF POSITION, THIS WILL TAKE AWAY FLOW
TO TOOL
3. PUT THE PACK ENGINE OFF
