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. See example in figure 1. This machine must be connected to an electrically ground circuit in order to protect the operator from electric shock. This machine has an approved power cord with three conductors as well as a plug with three terminals.
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 - Using the Dolly Cart CAUTION: CAUTION: When deploying the dolly, the drum will contact the floor or ground over which the machine is resting. Care should be taken to avoid surfaces which might damage or contaminate the drum.
How to Transport the Machine (cont.) 4. To store the dolly in the "UP" position, swing the dolly up against the top of the mainframe as far as it will travel and close the quick release levers to secure it in place. (See Figure 5) 5. To remove the dolly, loosen the quick release adjustment nuts until the levers and nuts clear the counter-bore on the dolly brackets, and remove the dolly. 6. Tighten the adjustment nuts until the quick release levers can be closed to secure the dolly in place.
ÂÂ CAUTION: Premature bearing failure can occur if the fan belt is set too tight. The fan belt should deflect ½" at the center of the span with 5 lbs. of pressure. NOTE: It is necessary to adjust the fan belt independently during this procedure or during replacement. The idler pulley is factory adjusted. Transporting the Machine by Carrying - Two People 1. Person #1 places his hands under the front of the machine's main casting. 2. Person #2 lifts the machine by the operating handle.
Machine Set-Up (Cont) 7. Install a new abrasive belt by sliding the abrasive over the tension roller and contact wheel. (See figure 12) 8. Rotate the release lever backward to tighten the abrasive belt. CAUTION: Do not force the release lever. Doing so can damage the tracking mechanism and cause the abrasive belt to mis-track. Figure 12 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.
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.
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.
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 Clarke 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’s Sander 16. To minimize chatter when using a belt or drum sander the following steps should be taken: 1. DRUM MARKS...are caused by the operator lowering the drum to the floor without forward traverse.
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.
Sander Adjustment Procedures (cont) 2. Drive the adjusting screw in, to sand heavier on the left (the drive belt side). Back the adjusting screw out, to sand heavier on the right (the side opposite the drive belts). Test the setting on an even surface. Make further adjustments if necessary. 3. Mark new pointer location on main frame Belt Tracking WARNING: AA Injury to the operator could occur if any machine adjustments are made while the motor is running.
Sanding Adjustment Procedures (Cont) To decrease the travel or reduce the reach on the grip control follow this procedure: 1. Loosen the locknut on the control rod. (See figure 20A) 2. Screw the control rod adjuster"out" until desired reach is found. 3. 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 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.
