Variable Speed The variable speed dial located on the control panel allows you to increase the feed rate from 020 FPM. The correct speed to use depends on the type of stock you are using (hardwood vs. softwood) and the stage of finish you are at with that stock. As a general rule, a slower feed rate will sand the surface smoother, but runs the risk of burning the wood; a faster feed rate will remove material faster, but runs the risk of overloading the motor. Use trial-and-error to determine the best settings for your specific applications. Load Meter The load meter located on the control panel displays the current amperage draw of the drum motor. The needle rises when you increase the load on the sanding drums and decreases when you decrease the load. Use this meter to avoid overloading your machine with too heavy of a cut. NEVER exceed 25 amps—this is the maximum that your machine can safely handle! Since various types of stock will react differently with various loads, use trial-and-error to determine the best settings for your applications. As a general rule, always start with a small load and work your way up. We recommend that you do not push your machine to its maximum load; instead, make multiple passes or install a coarser grit paper. Operation Under most sanding conditions, a normal cut is no more than 1.64". This depth can be achieved by approximately 1.4 turn of the handle. Excessively heavy cuts can cause jamming, wood burning, rapid paper wear, poor finish and belt slippage. We recommend that wide stock be sent through two to three times without adjusting the table height—this is important for preventing burned wood or ruined sandpaper. Also, turn the stock 180° to ensure an even cut. The following is the correct start-up and operating procedure for this model. 1. Start the dust collector. 2. Place stock on the conveyor table and turn the table handle to raise the conveyor table until the stock barely touches the pressure bar. 3. Start the drum motor and the feed motor. Pass the stock through the sander and slowly raise the conveyor table while listening for stock-to-drum contact. As soon as you hear contact, stop raising the table and watch the load meter (if it gets too high, immediately lower the conveyor table). Retrieve your workpiece by standing to the side of the sander—NOT directly behind it. 4. Without moving the table, make multiple passes and check your workpiece. 5. Check the sanded piece. Is the piece smooth? Mark a squiggly pencil line on a board and sand it to test for even sanding. Look for uniform removal of the line. If the line is not removed uniformly, refer to the Adjustments section earlier in the instruction manual. -24- G1066/G1066Z/G1079 Drum Sander Hook & Loop Sandpaper Although hook & loop sandpaper is convenient and easy to install, care must be taken not to overload it while sanding by taking excessively heavy cuts. Excessively heavy cuts will cause the underlying hooks and loops to slightly depress and deform under the sandpaper, resulting in small surface grooves and ridges on all subsequently sanded pieces. If this should happen, the only way to correct the situation is to unwrap and then re-wrap the sandpaper around the drum to “reset” the hooks and loops. Simply stated: DO NOT take excessively heavy cuts. If you need to remove material faster, switch to a coarser grit of sandpaper. Choosing Sandpaper There are many types of sanding belts to choose from. We recommend Aluminum Oxide for general workshop environments. Below is a chart that groups abrasives into different classes, and shows which grits fall into each class. Grit Type 60 Coarse 80-100 Medium 120-180 Fine 220 Very Fine The general rule of thumb is to sand a workpiece with progressively higher grit numbers, with no one grit increase of more than 50. The Model G1066/G1066Z/G1079 allows you to place two different grit sandpapers on each drum.The first drum should have a coarser grit than the second. Usually this translates into combinations of successive group types. A common selection for stock that is planed before being sanded is a 100/150 grit combination. Ultimately, the type of wood you use and your stage of finish will determine the best grit types to install on your sander. G1066/G1066Z/G1079 Drum Sander -25 -26- G1066/G1066Z/G1079 Drum Sander SECTION 7: MAINTENANCE General Lubrication Bearing blocks must be lubricated every 20 hours of operation. Use a high-quality, lithium-based grease. The grease fittings are located on the top of each bearing block. Other moving parts such as chains should be lubricated periodically with a light machine oil. Motor bearings need no lubrication. Use only adequate lubrication. Too much lubricant will attract dirt and sawdust and will clog the chain mechanism. Make a habit of inspecting your Model G1066/G1066Z/G1079 each time you use it. Check for the following conditions and repair or replace when necessary. • Loose mounting bolts. • Worn switch. • Worn or dam...
