Hold and continue to drill the hole. Switch off the machine briefly and relock the adjusting sleeve.
Rotary drilling only
Fig. 5: Unlock the adjusting sleeve. The quick-release chuck is used at this setting. Commercially available twist drills can be used in the quick-release chuck.

OPERATING INSTRUCTION FOR UNDERWATER TOOLS

Before working under water

• Check the machine with regard to leakages
• Check the machine regarding functioning of all parts (drilling, striking, actuating valves, etc.)
• Spraying of all moving parts with spray OKS 8604 (or similar).
• Fitting the tools with grease.

After having worked under water

• Clean the machine
• Dry the machine by blowing out with compressed air
• Spraying of all moving parts with spray OKS 8604 (or similar).
  For additional information refer to the machine specific operation and maintenance manual as well.

Maintenance Instructions
Our pneumatic motors are designed for an operation pressure of 4 -6 bar (65-90 PSI).
Service life and performance of the machines are decisively determined by:
a) The air purity
Blow the air hose clear before connecting it to the machine. Install dirt and water separator upstream of the machine, if it is not possible to prevent the formation of rust and water condensation in the air distribution lines.
b) The lubrication conditions and maintenance see „Maintenance of pneumatic tools“

The proper quantity of grease is very important with regard to good lubrication and low heat generation. The grease quantities listed in the following table must be complied with:

Maintenance of pneumatic tools

Only proper maintenance can ensure constant performance, reduction in wear and thus, a decrease in operating costs and an increase in service life.
Our pneumatic tools are equipped for an operating pressure of 6 bar. A regulator setting for an operating pressure of 4 bar is possible as well as expedient for grinding
machines with a built-in regulator so as to take full advantage of the speed prescribed for the corresponding grinding wheels.
Pneumatic tools should not run empty, because this results in heat and higher wear. The compressed air should be clean and dry.
This is guaranteed by a proper pneumatic system. Blow through the pneumatic hose before connecting it.
For the economical use of pneumatic tools. The prescribed air quantities are necessary, i. e. , the line, armatures and hoses must have the required cross sections so that the flow pressure remains constant.
Proper lubrication is a must; for this reason, our pneumatic tools usually have built-in oilers. Which are located between the inlet valve and the motor, and which function in any position. In smaller and lighter hand tools, these oilers must often be left out, because the machines would then be too heavy and not easy to manage. In such
cases, lubrication must be carried out by service units or by manual hose oilers. We recommend service units for permanently installed workplaces (see accessories list). However, where longer hose lines are necessary.
line oilers built into the hose lines are more effective. The distance between the tool and oiler should not be more than 5 m. Most of pneumatic tools have located at the connection a lined-up screen, which is to be regularly checked and cleaned.
After ending a working task, the machines are to be flushed with a thin oil, or protected some other way against corrosion.
Visible grease nipples are provided for regular lubrication of the gears with a grease gun. Note the following for grease lubrication: Every 60 hours of operation check striking
mechanism, friction bearings and antifriction bearings; if necessary, grease them.
Every 300 hours of operation grease the gears and antifriction bearings anew.
In the case of impact wrenches, use a grease gun to grease the anvil guide before beginning daily work or every 6 to 8 hours.
All inner parts must be lubricated before storing for longer periods of time in order to prevent rusting.
It is recommended to check the vanes and bearings at regular intervals. Store pneumatic tools in dry rooms only.
Lubricating oils to be used:
Generally SAE 5 W to SAE 10 For gearless impact wrenches and small grinders, only SAE 5 W.
For damp compressed air, oils are to be used that take up water ( without losing the lubricating effect) and that contain anticorrosive additives. At lower temperatures (especially for work outside) it may be necessary to use an antifreeze lubricant (e.g. Kilfrost, BP Energol AX 10, Kompranol N 74).
For saw-chain lubrication on chain saws:
Machine oil with adhesive additive, viscosity c ST 49-55’ (6.5-7.5 E)/ 50°C

Greases ( free of resins and acids)
Multi-purpose greases for antifriction and friction bearings Special greases for high-speed miter gears

Before starting: Check correct oiler setting!

Oiler types used on or with our tools

Oiler to mount on the machine or connect in the hose line
Setting the oiler: The adjustment screw item 2 is visible after removing the screw plug item 3. Theoil supply is decreased by tightening the screw, and by loosening the screw, more oil gets into the machine. In most cases it is sufficient to tighten or loosen the screw by ¼ or ½ of a turn. When plugged, clean borehole (dia. 2 mm) with wire.
Correct setting; When under pressure and with the filler screw (item 4) open, the oil must bubble slightly. The fillint lasts for approx. 8 operating hours.

Line oiler
For stationary pneumatic machines and motors, the lubrication is carried out by lined-up oilers for horizontal or vertical installation.
Setting of oilers: Shut off air supply. Open plug item 3.
Loosen visible lock nut item 5 with a socket wrench.
Using a screw driver turn back the tightened screw plug item 4 by ¼ to ½ of a turn and then lock again.
No oil is to get into the borehole “a” when filling. Close plug item 3 and open the air supply.
Correct setting: A piece of paper held for a short time in front of the outlet must be coated with oil without drops forming.

Transparent oiler
For installing in permanently equipped workplaces (especially for type using service units – see accessories list)
The transparent supply containers allow for good checking as well as for good setting possibility by means of a screw driver via a set screw with visible dripping. (The set screw is above the lateral thread connection – turning to the right for less oil; turning to the left for more oil) The setting (2 to 5 drops per m³/min air consumption) is to be carried out when air is flowing through, i.e., when the machine is running.

Spare Parts and Accessories
Only original spare parts may be used. There is no warranty for damages and liability is disclaimed, if non-original spare parts and accessories are used.
The repairing of the machine is allowed authorised expert companies only.
The accessories applicable with our machine are listed in our brochure.
