Clean Up Site Considerations The unpainted surfaces are coated with a waxy oil to protect them from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser such as Grizzly’s G7895 Degreaser. To clean thoroughly, some parts may need to be removed. For optimum performance from your machine, make sure you clean all moving parts or sliding contact surfaces that are coated.
Beginning Assembly Floor Mounting This section will cover the basic assembly and adjustment instructions needed to begin operation. Complete the assembly in the order provided in this manual and then read the remaining portion of the manual before attempting any type of operation. To mount the sander to the floor: Your safety is important! Please follow the warnings below during this entire section: Mount the sander to wooden floors with 1⁄2" lag bolts and washers.
Air Line Hook-Up To hook up the air line: 1. Connect the hose from your air compressor to the air inlet (Figure 7) on the regulator. 2. Make sure the red handle on the regulator is in the open position (parallel with the air inlet). Dust Collection An efficient and clean dust collection system is essential to the proper function of the sander. Ensuring a healthy work environment is also dependent upon cleaning and maintaining your dust collection system. To hook up the dust collection system: 1. 3.
Sanding Belt 4. Remove the spacer block (Figure 10). 5. Install the sanding belt by starting first on the upper roller and then the lower roller. Note— The sanding belt must be centered between the limit switches. If either edge of the sanding belt is touching either limit switch, turn the belt tension switch off and adjust the belt until it is properly centered as shown in Figure 11. To install the sanding belt: 1. Disconnect the sander from the power source! 2.
Pressure Rollers The pressure rollers have been set at the factory, but for safety, you should verify that they are set below the level of the sanding roller. Serious personal injury could result if the machine is connected to the power source during assembly or adjustment.
Starting the machine: 1. Wear safety glasses at all times when running the machine! 2. Connect the machine to the power source. 3. Press the TABLE UP and TABLE DOWN keys. The table should go up and down smoothly. 4. Press the FEED BELT START and FEED BELT STOP buttons. The feed belt should start, run and stop smoothly. 5. Press the SANDING BELT START and SANDING BELT STOP buttons. The sanding belt should start, run and stop smoothly.
SECTION 6: OPERATIONS Before Sanding Your safety is important! Please follow the warnings below during this entire section: Choosing Sandpaper NOTICE #100 and #150 grit sanding belts are included with the Model G0527. To avoid serious personal injury, read and become familiar with the entire instruction manual before using the Model G0527. Damage to your eyes, lungs, and ears could result from failure to wear safety glasses, a dust mask, and hearing protection while sanding with this machine.
Table Movement Adjusting Feed Rate The table height can be adjusted either manually or by power assist. The feed belt motor and gear assembly (Figure 13) controls the speed of the feed belt. The Model G0527 features feed belt speeds of 16.4, 23, and 32.8 FPM. Manual Adjustment—Manual adjustments are made by turning the handwheel located under the front of the infeed table. The thickness measurement is displayed on the digital readout.
Amperage Meter Sanding Workpiece The amperage meter is located above the control panel as shown in Figure 14. Use the meter to monitor the amperage load on the machine while performing sanding operations. Typically, no more than 0.5mm (approx. 1⁄64") of material is removed during each pass. Attempts to remove too much material can cause jamming, wood burning, rapid paper wear or tearing, poor finish and belt slippage. The following is the correct sanding operating procedure: 1.
SECTION 7: MAINTENANCE General Schedule Your safety is important! Please follow the warnings below during this entire section: The following items should be checked each time the sander is used: ON OFF Disconnect power to the machine when performing maintenance, assembly or adjustments. Failure to do this may result in serious personal injury. Loose hair and clothing could get caught in machinery causing serious personal injury.
Servicing Brakes 3. Pull the mounting pins out of the caliper bracket and remove the air line from the caliper. The caliper should now be able to be removed as in Figure 15. Eventually the brake pads will wear out. Checking and replacing these is a simple project that can be done in the shop, with the exception of having the rotor resurfaced. 4. The brake pads are secured to the caliper with cap screws.
Air Circuit Filters Clean Sanding Belts The air filter on the Model G0527 is located on the main regulator (Figure 16). Empty the filter trap as it becomes filled with moisture and dirt. The internal white filter should be replaced yearly. You can greatly increase the lifespan of your sanding belts if you clean them often. As mentioned on page 35, cleaning pads are the fastest way to clean wood dust from the sanding belts. Regulator Filter Trap Drain Valve Figure 16. Regulator filter trap.

SECTION 8: SERVICE ADJUSTMENTS Calibration NOTICE 7. Using a precise micrometer or set of calipers, measure the thickness at various points around the board. 8. Continue sanding the board until the average thickness measurement is within +⁄-0.003". Note—The final several passes should be done without adjusting the table height. This ensures the most consistent average thickness. 9. Make note of the digital display read-out. It should be the same as the average thickness of the sanded wood.
Feed Belt Tension Feed Belt Tracking To adjust the feed belt tension: 1. Disconnect the sander from the power source! 2. Raise the safety guard (Figure 17) on the front end of the feed table. 3. Increase or decrease the feed belt tension by adjusting the bolts located on the left and right side of the front table roller (Figure 17). Note—When tensioned properly, you should not be able to lift the feed belt off the table surface or slide it back and forth. DO NOT sand boards with the guard removed.
Belt Oscillation NOTICE The oscillation adjustments have been performed at the factory and should require no further attention. However, we recommend verifying the settings. When the oscillation is correctly adjusted, the sanding belt oscillates to the left and to the right at the same speed and without coming into contact with the limit switches.
Table Parallelism Table Mounting Bolts NOTICE The table has been adjusted at the factory and should require no further attention. However, we recommend verifying that it is parallel with the sanding roller. Adjusting the table parallelism can be a very tedious task that takes a great amount of patience. DO NOT adjust the table unless you are having trouble sanding your workpiece to a uniform thickness. Take precise notes on any adjustments you make to any of the table elevation screws (Figure 20).
Pressure Rollers 5. Disconnect the sander from the power source! 6. Loosen the roller lock nuts (Figure 22) on the infeed pressure roller. Turn the adjustment bolts (Figure 22) to lower the pressure roller until it just touches the board. Note—DO NOT continue to lower the roller beyond that point. Note—Variables such as feed rate, depth of the cut, and the type of sanding belt can play a big part in determining the proper amount of downward pressure exerted by the rollers.
V-Belt Adjustment To adjust either V-belt: 1. Disconnect the sander from the power source! NOTICE 2. Loosen the lock nut (Figure 23 & 24). The V-belts have been properly adjusted at the factory and should require no further attention. If future adjustment is needed follow the instructions below. 3. Turn the adjustment nut up or down until the proper V-belt tension is achieved. Note—The V-belt should deflect 1" off of center when pushed with your finger.
