7.1 Protective clothing and equipment Caution! Wear hearing protectors! The supplied hearing protectors must be worn when using the machine. The following sound level values have been measured for the parquet floor sander KING COBRA according to DIN 45 645: Idle mode LEQ = 85 dB(A) Working mode LEQ = 87 dB(A) The noise produced when the machine is working depends on various factors. Local conditions such as room size and quality of the floor affect noise development. 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. Caution! Wear safety goggles! When using the parquet floor sander KING COBRA and when working on KING COBRA, always wear safety goggles to protect your eyes. Caution! Wear proper working clothing! When using the parquet floor sander KING COBRA and when working on KING COBRA, never wear loose clothing. This can get caught up in moving parts.

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. 2. Fasten the dust bag here using the Multiclip. 15 05/2011

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. The dust is collected in the dust bag. Even so, this cannot prevent fine and ultra-fine dust being produced when using the machine. Caution! Health risk! Wood dust, particularly when treated with impregnating agents, solvents and coatings, can cause allergic reactions (e.g. of the skin or respiratory system) after a sensitization period. Beech and oak dust is classified as being carcinogenic (cancer of the nasal mucous membranes). Dust from other kinds of wood is suspected of having a carcinogenic effect. Caution! Fire risk! No smoking while sanding! All ignition sources are prohibited in rooms where sanding work is being carried out! Air the rooms thoroughly. Together with an ignition source and the oxygen in the air, wood dust can cause fires and explosions. Caution! Fire risk! Sanding over metal parts such as nails can produce sparks which are blown into the dust bag together with the wood dust. Here the glowing metal chips can still cause a fire even hours later. Every time after the machine has stopped and at the end of working, the sanding dust contained in the dust bag must always be disposed of immediately in a fire-proof, non-flammable container. The container must be covered with a fire-proof, non-flammable lid. Store the container only outdoors.

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. The container must be covered with a fire-proof, non-flammable lid. Store the container only outdoors. Caution! At the latest when 1/3 full, the sanding dust contained in the dust bag must be disposed of, because the dust collecting capacity is reduced when the bag is any fuller. The sanding dust must be disposed of in a fire-proof, non-flammable container. The container must be covered with a fire-proof, non-flammable lid. Store the container only outdoors. Caution! Always wear a respirator when disposing of the sanding dust (included with the accessories). 17 05/2011

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. Always wear safety gloves when replacing the sanding belt. Instructions for replacing the sanding belt: 1. Switch the machine off. 2. Disconnect the machine from the mains power. 3. Open the sanding drum cover (1). 4. Move the tension lever (2) forward. The sanding belt which was held under tension is now released. Pull it out to the side. 5. Insert a new sanding belt. 6. Clamp the new sanding belt by moving the tension lever (2) backward. 7. Close the sanding drum cover (1).

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. Hitting a nail while sanding can produce sparks and can cause a fire. For example a spark can create a fire in the dust bag. Floors are sanded in sanding paths which are arranged overlappingly from left to right.

floor is not sanded over an area of approximately 1.5 m to the wall behind the sander. Turn the machine 180° and sand the remaining area of the floor also in sanding paths which are arranged overlappingly from left to right. Make sure that the two areas are blended together without leaving any marks. Note! In most cases, the floor is sanded in several procedures. The whole floor area is sanded down in every sanding procedure. Informations about the proper abrasive grits, sanding pressures and sanding directions for the several sanding procedures you will find in the brochure: Sanding parquet and plank floors with the PALLMANN parquet floor sander COBRA and the PALLMANN edge sander GECKO S

1. Before starting the machine, the main lifting lever for the sanding drum (1) must be in the rear position. The sanding drum is clearly raised from the floor. The distance to the floor is approx. 15 mm. 2. Before starting the machine, ensure that the sanding belt is tightened. 3. Bring the machine into the start position. 4. Set the switch to setting "I".
