Caution! Wear a respirator! When using the parquet floor sander KING COBRA and when disposing of the sanding dust, always wear a respirator (see chapter 7.3 and 7.4). Wear the respirator which is supplied with the accessories.
Fitting the dust bag Caution! Only use original PALLMANN dust bags for the parquet floor sander COBRA. Caution! The dust bag must be firmly fitted to the dust pipe before sanding. Instructions: 1. Pull the dust bag over the dust pipe to behind the pipe reinforcement.
Safety instructions regarding dust Caution! Ultra-fine sanding dust! Always wear a respirator when sanding parquet and plank floors (is included with the accessories). When the machine is used for its proper purpose, the sanding of wooden floors naturally produces dust. The machine has an integrated dust collecting system which blows the dust into the dust bag.
Disposing of sanding dust Caution! Fire risk! Because of the fire risk, the sanding dust contained in the dust bag must always be disposed of immediately every time after the machine has stopped and at the end of working. The sanding dust must be disposed of immediately in a fire-proof, non-flammable container.
Replacing the sanding belt Caution! Danger from machine starting up! When replacing the sanding belt, there is a risk from the machine starting up unintentionally. Always disconnect the parquet floor sander from the mains power before working at the sanding belt. Caution! Risk of cutting your hands! The sanding grains of the sanding belt have sharp edges.
Adjusting the sanding pressure Use the pressure regulating bolt to adjust the required sanding pressure. High sanding pressure: Turn the pressure regulating bolt inwards as far as it will go. Low sanding pressure: Turn the pressure regulating bolt outwards to the marking (2) on the bolt thread.
Caution! Mortal risk from electric shock! Running over the electric cable with the sander entails a mortal risk from electric shock! Never point the machine towards the cable! Connecting the KING COBRA to the mains power 05/2011...

Remarks about sanding parquet and plank floors Caution! Check the floor to see if any boards are loose. These must be fastened before sanding. Caution! Fire risk! If there are nails in the floor, they must be countersunk so low every time before sanding that there is no risk of hitting a nail while sanding.

If with time the sanding belt fails to run concentrically to the sanding drum, the tension roller must be newly adjusted. Caution! Danger of injury! Adjustments of the sanding belt while the machine is running and the sanding drum cover is open may only be performed by qualified personnel (in accordance with VBG 1,...
