Prior to starting work
Check:
• The oil level, if necessary, refill oiler (line oiler or maintenance unit)
• If the drill bit is firmly clamped to the drill chuck.
• If the pneumatic hose is correctly connected.
Start the machine by actuating the valve trigger 1 and start operation. (The speed can be adjusted by
opening the valve more or less, or by increasing, respectively lowering, the drill pressure.)
After finishing the work
• Shut the valve.
• Shut compressed air supply and disconnect air hose.
• Dismount drill bit, if necessary.
Before underwater operation
Ensure that:
• The exhaust hose is connected and fixed at the supply hose.
• The exhaust hose is long enough to protrude above the water. In case of a short exhaust hose (in
the water) a reverse valve is used, so that water cannot get into the machine when plunging with the
machine.
• The machine is tested for leakage and for the functioning of all parts (drilling, blowing, valves, etc.).
Notice: Keep in mind that 10 meter water depth corresponds to 1 bar.
When working in greater depths match the diameter of the supply and exhaust hose appropriately.
After underwater operation
• Clean and dry the machine with compressed air.
• Spray all moving parts with multi-oil-spray.
Read operation instructions/safety instructions!
Before working on or with the tool, read the safety instructions and follow the
instructions during operation.
Do not modify the machine or the machine tools and accessories after receipt. Any constructive changes
or modifications need the manufacturer`s acceptance and have to be in compliance with the safety
instructions. Use the machine only for its determination. Consider the technical data of the equipment and
the ambient temperatures. Pay attention to labels, restrictions of use and special instruction notes on the
machine tools and the machine itself. Check regularly that the type plate and symbols on the machine are
legible. If necessary, contact the manufacturer to replace them. Only operators with technical knowledge,
trained by authorized responsible technical personnel, may install, adjust, operate, transport and store the
machine.
