Fig. 4: When starting to drill into brittle materials (tiles etc), unlock the adjusting sleeve to "rotary drilling only", hold

the machine by the adjusting sleeve and press it slowly against the work surface until it hammers weakly. Hold and

continue to drill the hole. Switch off the machine briefly and relock the adjusting sleeve.

Fig. 5:Rotary drilling only

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.

Before working under water

•

Check the machine with regard to leakages

•

Check the machine regarding functioning of all parts (drilling, striking, actuating valves, etc.)

After having worked under water

•

Clean the machine

•

Dry the machine by blowing out with compressed air

•

Spraying of all moving parts with Multi-Oil-Spray (or similar).

For additional information refer to the machine specific operation and maintenance manual as well.

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:

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.

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:

In the crank casing

In the bevel gears

In the spur gears

Only proper maintenance can ensure constant performance, reduction in wear and thus, a decrease in operating costs

and an increase in service life.

Our hydraulic tools are equipped for an operating pressure of up to 100 bar. Regulator setting for a lower operating

pressure is possible.

The tools should not run empty, because this results in heat and higher wear of the output section and the tool

holder. The hydraulic oil should be clean. This is ensured by professional equipment. Clean the connecting parts before

connecting the hydraulic hoses.

For an economic use of the hydraulic tools the required sizes of pipe, fittings and hoses have to be adjusted.

Proper greasing of the gear and the tool heads is a must. See the operation manual on this.

After finishing the work the tools have to be cleaned and protected against corrosion.

Visible grease nipples are provided for regular lubrication of the gears with a grease gun, or the gearboxes have a

long term greasing.
