OPERATOR SAFETY INSTRUCTIONS WARNING AVERTISSEMENT ADVERTENCIA DANGER means: Severe bodily injury or death can occur to you or other personnel if the DANGER statements found on this machine or in this Owner's Manual are ignored or are not adhered to. Read and observe all DANGER statements found in this Owner's Manual and on your machine.
DANGER: Electrocution could occur if maintenance and repairs are performed on a unit that is not disconnected from the power supply. Disconnect the power supply before attempting any maintenance or service. DANGER: Electrocution could occur if machine is used on ungrounded electrical circuit. Never remove or disable the grounding supply conductor on the electrical cord. Consult an electrician if the grounding conductor is missing or if you suspect your circuit is not grounded properly.

230V Electrical Connection Instructions CAUTION: This machine will operate only on AC frequency and on electrical voltage shown on the motor nameplate. Make sure you have the correct frequency and voltage before connecting the power cord to an outlet. The machine has a plug as shown in figure #1. This machine must be connected to an electrically ground circuit 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. Use proper lifting techniques. Transporting the Machine - One Person To transport the machine, follow this procedure: 1. Make sure the power cable is disconnected from the electrical outlet. 2. Disconnect the handle pigtail cord connection. (twist and pull) See figure #2. Figure 2 3. Loosen the belt tension T-screw completely. 4.
How to Transport the Machine (cont.) Note: It is not necessary to adjust the fan belt independently during this procedure or during replacement. The idler pulley is factory adjusted. 6. Close the belt guard door. 7. Plug the motor pigtail in, twisting to lock. Transporting the Machine - Two People When transporting the machine with two people follow this procedure. Figure 5 1. One operator places hands under the front of the machines main casting. 2. Person #2 lifts the machine by the handle.
7. Install a new abrasive belt by sliding the abrasive over the tension roller and contact wheel. See figure #8. 8. Rotate the release lever upward and back to tighten the abrasive belt. 9. Make sure the motor circuit breaker is in the "Off" position. Plug the pigtailed power cord into the handle. Twist the cord connection clockwise to lock. 10. Jog (turn on momentarily) the motor circuit breaker while observing the belt tracking.
How to Operate the Machine DANGER: DANGER: DANGER: DANGER: DANGER: Page 10 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.
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. 9.
Sanding Cuts and Sandpaper Initial Cut Final Cuts 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.
Chatter Wave Prevention American 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 American Sanders Technology’s Sander 16. To minimize chatter when using a belt or drum sander the following steps should be taken: 1. DRUM MARKS...
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. The following information provides details on how to adjust different features/controls of the sander.
The machine is factory set and no adjustments should be necessary. After any maintenance is performed to the carriage system, pointer must be returned to original mark (See figure 13). If it is necessary to reset level after replacing wheels follow this procedure: 1. Lower contact wheel and loosen all three clamping nuts. 2. Drive adjusting screw in, to sand heavier on the left (the drive belt side). Back adjusting screw out, to sand heavier on the right (the side opposite the drive belts).
Sanding Adjustment Procedures (CONT) To decrease the travel or reduce the reach on the grip control follow this procedure: 1. Hold the control rod and loosen the locknut. See figure #16. 2. Screw the control rod out until desired reach is found. 3. Hold the control rod and tighten the locknut. Routine Maintenance The following items need to be periodically inspected and maintained to keep your sander in good working condition.
Bearings Periodically check the bearings for wear or damage according to the following schedule: Guide rollers Idler pulley Fan shaft Tension roller Arbor shaft Motor shaft after 1st 650 hrs. after 1st 1500 hrs. after 1st 2500 hrs. after 1st 2500 hrs. after 1st 5000 hrs. after 1st 5000 hrs. Rollers Periodically check the guide rollers and the tension roller for wear.
Troubleshooting Problem Cause Action Drive belts slip. (Squeaking or squealing sound) Insufficient tension. Tension drive belt as described in adjustment procedures. (See pg. 7) Worn belts. Replace belts. Squealing, growling or grinding noise coming from machine. Damaged and/or worn bearing. Remove drive belts, rotate arbor motor, fan, shafts and idler pulley to locate dragging or rough bearing. Contact an authorized ALTO dealer. Dust pickup is poor. Dust bag is over 1/3 full.
Troubleshooting Problem Cause Action Burning or glazing. Dull abrasive. Replace abrasive. Excessive sanding pressure. Decrease sanding pressure setting. (Fig. #12, page 14). Too fine of an abrasive belt. Use coarser abrasive. Dull abrasive. Replace abrasive. Too fine of an abrasive belt. Use a coarser abrasive belt. Insufficient sanding pressure. Increase sanding pressure setting. (Fig. #12, page 14). Debris on wheels. Remove and clean wheels. Flat spot on tire(s). Replace tires.
