Electrical Connection Instructions CAUTION: This machine will operate only on AC frequency and 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 below. Figure 1 Note: European machines are not equipped with an electrical plug. 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. 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. 3. Loosen the belt tension T-screw completely. 4.
NOTE: It is not always necessary to adjust the fan belt independently during this procedure or during replacement. NOTE: New drive belts may shed particles of rubber until seated to the pulley grooves. This seating process can take up to 24 hours to accomplish. 6. Close the belt guard door. 7. Plug the motor pigtail in. Twist clockwise to lock. Transporting the Machine - Two People When transporting the machine with two people follow this procedure: 1.
Machine Set-Up To set-up your machine follow this procedure: 1. Familiarize yourself with the machine and read all danger, warning and caution statements. 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.
How to Operate the Machine DANGER: Sanding/finishing wood floors can create an environment that can be explosive. Cigarettes, cigars, pipes, 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 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 9. 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 belt 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 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.
Leveling To adjust the machine leveling follow this procedure: 1. Locate the leveling screw. See figure 13. The leveling screw is located towards the rear of the chassis beneath the sanding pressure knob. 2. Tighten the leveling screw (compress the leveling spring) to sand heavier on the left (drive belt side). 3. Loosen the leveling screw (relax the leveling spring) to sand heavier on the right (side opposite the drive belts).
Routine Maintenance The following items need to be periodically inspected and maintained to keep your sander in good working condition. Sanding Chamber Periodically blow out the sanding chamber to prevent accumulations of debris which could interfere with the performance of the tension roller. Wheels Periodically remove the debris from the truck and caster wheels. Debris can cause waves on a sanded surface. Dust Bag Remove the dust bag from the machine and shake it thoroughly to remove the sanding dust.
