230V Electrical Connection Instructions CAUTION: This machine will operate only on AC frequency and on electrical voltage shown on the equipment nameplate. Make sure you have the correct frequency and voltage before connecting the power cord to an outlet. See the example in figure 1. This machine must be connected to an electrical source with an earthing conductor in order to protect the operator from electric shock.
How to Transport the Machine WARNING: The machine is heavy. Remove the motor from the machine before transporting. Get help loading the machine and motor. To transport the machine, follow this procedure: 1. Make sure the power cable is disconnected from the electrical outlet. 2. Disconnect the handle plug connection. See figure 1. 3. Remove the belt cover. 4. Remove the fan belt. Figure 1 5. Loosen the motor bolt. Using the ¾" wrench, turn the motor bolt counterclockwise. See figure 2. 6.

Make sure all operators of this machine have read this Owner's Manual. If they cannot read English, have the manual explained fully before allowing anyone to operate the sander. 2. Locate the power supply. The receptacle should be compatible with the plug. The receptacle must be grounded and must be fused (30 amp) to avoid an electrical hazard. 3.
8. Put the smooth side of the abrasive against the sanding drum. 9. Put one end of the abrasive against the sanding drum slot (1). See figure 3. 10. Turn the drum one revolution. Put the other end of the abrasive in the drum slot (2). See figure 3. 11. Tighten the abrasive. To tighten the abrasive, follow this procedure: 1. The end wrenches are given with the machine. Put a wrench around the nut at each end of the durm (1). See figure 4. Figure 3 2.
How to Operate the Machine DANGER: Sanding/finishing wood floors can create an environment that can be explosive. Cigarette lighters, pilot lights and any other source of ignition can create an explosion when active during a sanding session. All sources of ignition should be extinguished or removed entirely if possible from the work area. DANGER: Work areas that are poorly ventilated can create an explosive environment when certain combustible materials are in the atmosphere, i.e.
To operate the machine follow this procedure: 1. Install the operator's belt as follows: a. Position the operator's belt around waist. b. Cross the straps at the waist. See figure 5. 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.
A. First pass forward, right to left. B. First pass reverse, retrace same path. C. Second pass forward, overlap ½ the drum width. D. Second pass reverse, retrace second path forward, etc....for the entire room E. Work the remaining unsanded floor in the same fashion, right to left.
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 should be used. If the surface is severely damaged by deep scratches, pre-existing dwell marks, uneven planks, etc., it may be necessary to sand across or diagonally to the grain to restore evenness to the surface.
Sander Adjustment Procedures DANGER: Electrocution could occur if maintenance and repairs are performed on a unit that is not properly disconnected from the power source. Disconnect the power supply before attempting any maintenance or service. DANGER: Moving parts of this machine can cause serious injury and/or damage. Keep hands, feet and loose clothing away from all moving parts of the sander. Sanding Pressure To adjust the sanding pressure follow this procedure: 1.
Leveling If the sanding drum is out of adjustment, follow this procedure: 1. Remove the belt cover. 2. Loosen the eccentric lock screw. Using the 7/16" wrench, turn the eccentric lock screw (1) counterclockwise. See figure 7. 3. To raise or lower the drum, turn the eccentric (2). See figure 7. 4. Tighten the eccentric lock screw. To tighten the eccentric lock screw, turn the screw clockwise. 5. Install the belt cover.
Routine Maintenance The following items need to be periodically inspected and maintained to keep your sander in good working condition. Wheels Periodically remove the debris from the truck and caster wheels. Debris can cause waves on a sanded surface. Lubricate truck mechanism every 25 hours of use. The machine is equipped with lubrication fittings and are located on shaft supporting mechanism.
Troubleshooting Problem Cause Action Drive belts slip. Insufficient tension. Tension drive belt. (Squeaking or squealing sound) Worn belts. Squealing, growling or grinding Damaged and/or worn bearing. noise coming from machine. Replace belts. Dust pick-up is poor. Dust bag is over 1/3 full. Dust bag is dirty. Dust chute is obstructed.

Chatter - Wave Prevention Clarke American Sanders Sanders are designed and manufactured to the most rigid tolerances. However, after a finishing cut it is possible to see “chatter” or “waves”. The best guarantee to remove the chatter is to finish the floor with a rotating horizontal sander, such as Clarke American Sanders’s Sander 16. To minimize chatter when using a belt or drum sander the following steps should be taken: 1) DRUM PAPER...insure the paper is secured in the slot, but not too tight.
Chatter - Wave Prevention (cont) 3) UNEVEN WALKING PACE..... can leave lengthy “waves”. The machine cuts more material during the slower pace. Pay particular attention to a steady, even pace. 4) EXCESSIVE LIGHT CUTS.... may reveal high spots on the paper/contact wheel and cause chatter. Take a heavier cut and increase the pace. 5) DEBRIS.... lodged between the paper and the drum will leave chatter. On a belt sander, debris may be adhered to the drum.
