Floor sanding machines can cause flammable material and vapors to ignite. Read the manufacturer's label on all chemicals used to determine combustibility. Keep the work area well ventilated. DANGER: Sanding dust can self ignite and cause an injury or damage. Remove the contents of the dust bag each time you finish using the machine. Always dispose of the dust in a metal container located outside of the building. Never leave a dust bag unattended with sanding dust in it. Empty the contents frequently. Do not empty the contents of the dust bag into a fire. DANGER: Hitting a nail while sanding can cause sparks and create an explosion or fire. Always use a hammer and punch to countersink all nails before sanding floors. To operate the machine follow this procedure: 1. Before sanding, decide on best approach for sanding desired area. If the floor is uneven, it may be necessary to sand diagonally to the direction that the floor is laid. This will help "pull" or stretch low and high spots in the floor over a greater area, producing a flatter surface. Premiminary cuts should be performed at angles approximately 15° to the direction of the wood grain. Cut direction should change on succesive cuts with the final cut performed in the direction of the wood grain. This will minimize the tendency of waves to form and provide the most even floor surface. When sanding the area, work in a way so that you are moving away from where the cord set enters the room. This will help to avoid entanglement with the cord set and eliminate the need to move the cord set out of the way so frequently. Work the area in a way that avoids interruption or termination points ( an end of pass.) Make long continuous passes. 2. Swing cable arm to side of machine opposite the direction you intend to work. Rotate elbow on dust pipe until dust bag rest on motor. This will maintain balance and sanding pressure as the dust bag fills. The machine should be operated with the dust bag in this position whenever possible. 3. If the operating belt (Clarke American Sanders PN 60724A) is used proceed as follows: a. Position the operating belt around waist. b. Cross the straps at the waist. See figure #13. c. Slide the belt loop end over the handle on the control lever side. Adjust the length as needed. d. Wrap the remaining strap around the opposite side of the handle, and hold it in place with your hand. WARNING: Serious operator injury could occur if the operator has tied or strapped the loose end of the operator's belt strap to the machine. Always wrap the strap so that you can let go and get away quickly in case of bag fire or explosion. 4. Activate the control switch. CAUTION: To prevent damage to the floor, make sure the machine is in motion when the contact wheel is engaged with the floor. 5. Feather-cut in by easing the contact wheel down onto the surface with the control lever while the sander is in motion. Clarke® American Sanders Operator's Manual (EN) - Floorcrafter - 11 ENENGLISH How to Operate the Machine ENENGLISH How to Operate the Machine 6. When contact wheel is fully engaged with the surface, gradually adjust your pace for adequate finish removal. Keep sander in motion while the contact wheel is engaged with the surface or dwell marks will occur. 7. Move the machine in the direction of the grain in the wood whenever it is possible. Sand the surface at a constant pace. 8. Gradually feather-cut out at the termination point by easing the contact wheel up with the control lever. (See Figure 13) 9. Repeat technique described in steps 5, 6, 7, and 8 and sand back down pass just made. When completed, begin a new pass by overlapping previous pass half the width of the abrasive. Stagger termination points to prevent a distinct ridge and a better blend when edging. 10.Empty contents of the dust bag into a metal container located outside the building. Dust bag should be emptied whenever full, as indicated on bag. Figure 13 WARNING: Do not overfill dust bag or seri ous fire may result. Never leave a dust bag containing dust unattended. Sanding dust can self ignite and cause a fire or explosion. Use only genuine Clarke American Sanders replacement bags. CAUTION: An overfilled dust bag may effect machine balance and performance. Do not handle or disturb dust bag and elbow while sanding or damage to the floor may occur. -12- Clarke® American Sanders Operator's Manual (EN) - Floorcrafter ENENGLISH Sanding Cuts and Sandpaper ENENGLISH Sanding Cuts and Sandpaper Initial Cut The purpose of the initial cut is to remove old finish and gross imperfections on the floor surface. The sanding equipment should be adjusted to heavy sanding pressure setting and a coarse abrasive belt should be used. If the surface is severely damaged by deep scratches, preexisting dwell marks, uneven planks, etc., it may be necessary to sand across or diagonally to the grain to restore evenness to the surface. If these conditions are not present, the initial cut should be done in the d...
