Additional Safety for Drum Sanders

FEEDING STOCK. Do not allow anyone to stand

in the path of the workpiece at the outfeed end when feeding your stock. Never sand more than one piece of stock at a time. Do not jam the workpiece into the machine during operation. Firmly grasp the workpiece in both hands and ease it into the machine using light pressure.

MINIMUM STOCK DIMENSIONS. Do not sand any stock thinner than shorter than 6". Do not sand thin stock by using a “dummy” board under your workpiece.

CLOTHING. Do not wear loose clothing while operating this machine. Roll up or button sleeves at the cuff.

HAND PROTECTION. Do not place hands near, or in contact with, sanding drums during operation. Do not allow fingers to get pinched between board and conveyor belt during operation. This may pull the operator’s hand into the machine and cause serious injury!

⁄8", narrower than 1⁄8", or

DUST COLLECTION SYSTEM. Never operate the sander without an adequate dust collection system in place and running.

UNAT TEND ED OPER ATION . Never leave the machine running unattended.

REPLACING SANDING PAPER. Replace sanding paper when it becomes worn.

EXPERIENCING DIFFICULTIES. Any problem, with the exception of conveyor belt tracking that is concerned with any moving parts or accessories, must be investigated and corrected with the power disconnected, and after all moving parts have come to a complete stop.

MAINTENANCE AND ADJUSTMENTS. Never attempt to adjust conveyor belt tracking when the sanding drums are engaged. Perform machine inspections and maintenance service promptly when called for. Disconnect power before performing maintenance or adjustments on the sander.

INSPECTING WORKPIECES. Always inspect workpiece for nails, staples, knots, and other imperfections that could be dislodged and thrown from the machine during sanding operations.

Like all machines there is danger associated with this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to lessen the possibility of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

RESPIRATOR AND SAFETY GLASSES. Always

wear a respirator and safety glasses while operating the machine. Dust and chips are created when sanding. Some debris will be ejected, becoming hazards to the eyes and lungs.

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equipment, or poor work results.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrican or qualified service personnel in accordance with all applicable codes and standards.

Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

For your own safety and protection of

Note: The circuit requirements listed in this manual apply to a dedicated circuit—where only one machine will be running at a time. If this machine will be connected to a shared circuit where multiple machines will be running at the same time, consult a qualified electrician to ensure that the circuit is properly sized for safe operation.

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

This machine is prewired to operate on a 110V power supply circuit that has a verified ground and meets the following requirements:

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

We do not recommend using an extension cord with this machine. cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle, and meet the following requirements:

Grounding & Plug Requirements

Serious injury could occur if you connect

Dust Collection

DO NOT operate the Model G0458 without adequate dust collection. This sander creates substantial amounts of wood dust while operating. Failure to use dust collection can result in short and long-term respiratory illness.

You may attach the Model G0458 drum sander to a dust collection system if you do not use the included dust bag. If you are using your own dust collection system, we recommend using a system that can collect a minimum of 400 CFM AT THE

DUST PORT.

19. Slide the dust hose clamp over the dust

bag, insert the bag and clamp over the dust port (Figure 17), and secure with the clamp handle. DO NOT overtighten the clamping

adjustment or it may break!

Clamp

Dust Bag

Figure 17. Installing dust bag and clamp.

Dust Port

Note: Do not confuse this CFM recommendation with the rating of the dust collector. To determine the CFM at the dust port, you must take into account many variables, including the rating of the dust collector, the length of hose between the dust collector and the machine, the amount of branches or wyes, and the amount of other open lines throughout the system.

When the dust collection is working properly, a fine layer of dust may be present on your stock as it comes out of the sander. This is a normal characteristic of all drum sanders.

To connect the dust ports to a dust collector:

1. Attach a 2 port and secure with a hose clamp.

Adjustments

For your convenience, the adjustments listed below have been performed at the factory and no further setup is required to operate your machine.

Before starting the sander, make sure you have performed the preceding assembly and adjustment instructions, and you have read through the rest of the manual and are familiar with the various functions and safety issues associated with this machine. Failure to follow this warning could result in serious personal injury!

To test run the sander:

1. Put on safety glasses and make sure any

bystanders are out of the way and also wearing safety glasses.

2. Connect the sander to power.

3. Flip the ON/OFF switch ON. Make sure that

your finger is poised over the ON/OFF switch, just in case there is a problem.

The drum sander should run smoothly, with

little or no vibration or rubbing noises. Strange or unnatural noises MUST be investigated and corrected before operating the machine further. To avoid injury or damage to the machine, DO NOT attempt to make adjustments to the machine without turning it Off and unplugging it from its power source.

However, because of the many variables involved with shipping, some of these adjustments may need to be repeated to ensure optimum results. Keep this in mind as you start to use your new drum sander.

Step-by-step instructions for these adjustments can be found in SECTION 7: SERVICE ADJUSTMENTS.

1. V-Belt Tensioning (Page 27). Perform after

the first 16 hours.

2. Feed Belt Tensioning & Tracking (Pages 31 & 32).

3. Table Adjustments (Page 34).

Investigate and correct any problems before operating the machine further. If you need help, refer to the Troubleshooting section in the back of this manual or contact Tech Support at (570) 546-9663.

SECTION 4: OPERATIONS

Damage to your eyes, lungs, and ears could result from using this machine without proper protective gear. Always wear safety glasses, a respirator, and hearing protection when operating this machine.

Depth of Cut

The optimum depth of cut will vary based on the type of wood, feed rate, and sandpaper grit. Attempts to remove too much material can cause jamming, wood burning, rapid paper wear or tearing, poor finish, and belt slippage.

To set the depth of cut:

1. Rotate the table height handwheel (Figure

18) until the table is too low, then raise the

table, allowing a gap between the workpiece and the sanding drum.

Loose hair and clothing could get caught in machinery and cause serious personal injury. Keep loose clothing and long hair away from moving machinery.

NOTICE

If you have never used this type of machine or equipment before, WE STRONGLY RECOMMEND that you read books, trade magazines, or get formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training.

Note: When adjusting the table to sand a

thicker workpiece, lower and then raise the table to remove backlash from the adjustment mechanism.

Figure 18. Table height handwheel.

2. Turn ON the feed belt and sanding drum and

feed the workpiece into the sander. SLOWLY raise the feed belt until the workpiece makes light contact with the sanding drum. This is the correct height to begin sanding the workpiece.

Model G0458 (Mfg. Since 5/11)

3. After the initial pass, turn the handwheel up to

⁄4 turn (1⁄64" or 0.4mm)—the maximum depth

for most sanding conditions. Note: Each full

turn of the table height handwheel raises the feed table approximately 0.060" (

1.5mm.

⁄16") or

-19 -

Variable Speed

The variable speed knob allows you to increase the feed rate from 2–12 FPM. The correct speed to use depends on the type of stock you are using (hardwood vs. softwood) and the stage of finish with that workpiece.

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 or damaging the sandpaper.

Use trial-and-error to determine the best settings for your specific applications.

To adjust the feed belt speed:

Sanding

DO NOT sand more than one board at a time. Minor variations in thickness can cause one board to be propelled by the rapidly spinning sanding drum and ejected from the machine. NEVER stand directly in front of the outfeed area of the machine. Failure to do so could result in severe personal injury.

To sand a workpiece:

1. Adjust the table height according to the instructions in Depth of Cut on Page 19.

1. Turn ON the feed belt (DO NOT adjust con-

veyor speed when the conveyor motor is Off).

Adjusting the variable speed when the conveyor motor is Off can damage the V-belt and the adjusting mechanism.

2. Rotate the variable speed knob (Figure 19)

counterclockwise to increase the feed speed, or clockwise to decrease the feed speed.

2. Make sure the filter bag is secure (or start the dust collector, if connected) and turn the sander ON.

3. Feed the workpiece through the sander. Retrieve the workpiece by standing at the side—not at the outfeed end.

4. Run wide stock through two or three times without adjusting the table height. Turn the stock 180° between passes to ensure an evenly sanded surface.

Overloading the motor or pushing the sander to failure weakens the electrical system. Repeatedly doing so is abuse to the machine that will cause motor, capacitor, or thermal breaker damage, which is not covered by the warranty.

Sanding Tips

Choosing Sandpaper

• Replace the sandpaper with a higher grit to

achieve a finer finish.

• Raise the table a maximum of handwheel until the workpiece is the desired thickness.

• Reduce snipe when sanding more than one board of the same thickness by feeding them into the sander with the front end of the second board touching the back end of the first board.

• Feed boards into the sander at different points on the conveyor to maximize sandpaper life and prevent uneven conveyor belt wear.

• DO NOT sand boards less than 6" long or less than workpiece and the drum sander.

• Extend the life of the sandpaper by regularly using a PRO-STICK

24).

• When sanding workpieces with irregular surfaces, such as cabinet doors, take very light sanding passes to prevent gouges. When the drum moves from sanding a wide surface to sanding a narrow surface, the load on the motor will be reduced, and the drum will speed up, causing a gouge.

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 Class Usage

36 Extra Coarse Rough sawn boards,

thickness sanding, and glue removal.

60 Coarse Thickness sanding

and glue removal.

80–100 Medium Removing planer

marks and initial finish sanding.

120 –180 Fine Finish sanding.

The general rule of thumb is to sand a workpiece with progressively higher grit numbers, with no one grit increase of more than 50. Avoid skipping grits; the larger the grit increase, the harder it will be to remove the scratches from the previous grit.

Ultimately, the type of wood you use and your stage of finish will determine the best grit types to install on your sander.

• DO NOT edge sand boards. This can cause boards to kickback, causing serious personal injury. Edge sanding boards also can cause damage to the conveyor belt and sandpaper.

• When sanding workpieces with a bow or crown, place the high point up (prevents the workpiece from rocking) and take very light passes.

• Feed the workpiece at an angle to maximize stock removal and sandpaper effectiveness, but feed the workpiece straight to reduce sandpaper grit scratches for the finish passes.

SECTION 6: MAINTENANCE

Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury.

Schedule

For safe and optimum performance from a machine that is used on a daily basis, follow this maintenance schedule and refer to any specific instructions given in this section.

Daily Checks and Maintenance:

• Loose mounting bolts.

• Damaged sanding belt.

• Worn switch.

• Worn or damaged cords or plugs.

• Damaged V-belts.

• Any other unsafe condition.

• Oil the feed belt roller and drive bushings.

• Clean/vacuum dust buildup from inside cabinet and off of the motor.

Cleaning

Cleaning the Model G0458 is relatively easy. Vacuum excess sawdust, and wipe off the remaining dust with a dry cloth.

Lubrication

The feed belt bushings should be lubricated daily with a light machine oil. Lubricate the chains and gears with a high-quality, lithium-based grease. The bearings do not need lubrication.

Avoid using excess lubrication. Too much lubricant attracts sawdust and will clog the chain.

Bushings: Must be oiled daily or each time the sander is used. Oil the bushings on each end of the feed belt rollers and remove the pulley cover and oil the drive bushings (see Figure 29).

Model G0458 (Mfg. Since 5/11)

Pulley Alignment

Tools Needed: Qty

Hex Wrenches 4 & 8mm .............................. 1 Ea

Phillips Head Screwdriver ...................................1

Pry Bar ...............................................................1

Pulley alignment is another important factor in power transmission and belt life. The pulleys should be parallel to each other and in the same plane (coplaner) for optimum performance.

4. Remove the V-belts.

5. Loosen the set screws on the motor pulley

and align the motor pulley with the feed belt pulley.

6. Loosen the set screws on the sanding belt pulley and align the sanding belt pulley with the motor pulley.

7. Tighten the set screws, replace the V-belts, and repeat Step 3. Belts should be parallel and aligned as shown in Figure 39.

Each pulley can be adjusted by loosening the set screw that secures the pulley to the shaft, sliding the pulley in/out, and retightening the set screw to lock the pulley in place.

To align the pulleys:

1. Disconnect power to the sander!

2. Open the pulley cover.

3. Looking from the top, sight down the V-belts

and pulleys and check to see that the pulleys are parallel and aligned with each other (see Figure 39).

— If the pulleys are aligned, go to Step 9.

— If the pulleys are NOT aligned, perform

Steps 4 –8.

8. Adjust the pulleys again, if necessary, until they are all coplanar with each other.

9. Replace the pulley cover.

Feed Belt Tracking

Tools Needed: Qty

Wrench 8mm ......................................................1

Hex Wrench 4mm ...............................................1

The feed belt must track straight. If the feed belt tracks to either side, then the tracking must be corrected or the feed belt will become damaged and have to be replaced.

Tracking the feed belt is a balancing process that takes patience and a small degree of trial-anderror. Usually you must over-tighten the loose side (the side the belt is tracking towards) to make the feed belt move to the middle of the rollers, then loosen that same side to make the feed belt stay in position. If you adjust the bolt too much either way, then you have to repeat the process until the feed belt rides in the middle and stays there during continuous operation.

Note: Tracking affects tension, so tension must always be adjusted after tracking.

To track the feed belt:

1. Turn the feed belt ON and watch it track. If

the belt moves to one side, immediately stop the machine and adjust the belt tracking. If the belt tracks evenly, leave it alone.

-31-

2. Loosen the lock nut (Figure 40) on the side that the feed belt tracks towards and tension the tracking adjustment screw until the feed belt tracks in the opposite direction.

Note: Small tracking changes may take up to

three minutes before they are noticeable.

To tension the feed belt:

1. Loosen the feed roller lock screws, shown in Figure 41, on both sides of the feed belt.

3. When the feed belt is near the middle of the

rollers or table, loosen the tracking adjustment screw until the feed belt stops moving and tracks straight.

—If the feed belt tracks too far to the other

side, loosen the tracking adjustment screw as necessary to bring it back. Repeat Steps 2 & 3 until the tracking is correct.

The feed belt will stretch when new and will eventually need to be tensioned. This is most obvious if the feed belt starts slipping on the rollers.

When you tension the feed belt, focus on adjusting the tensioning bolts in even increments. Adjusting one side more than the other will cause tracking problems, which will require you to take additional steps to get the sander operating correctly.

Figure 41. Feed belt tensioning controls.

2. Use a permanent marker, paper correction

fluid, or fingernail polish to mark the feed belt tensioning bolt on both sides. This step will aid you in keeping track of the rotations as you turn the bolts, so they remain as even as possible.

3. Loosen the lock nuts and turn both of the feed belt tensioning bolts clockwise one full turn at a time until the feed belt no longer slips during operation.

—If the feed belt starts tracking to one side,

back off the feed belt tensioning bolt that is being adjusted.

—If the feed belt continues tracking to one

side, immediately turn the drum sander Off and perform the tracking instructions.

4. Tighten the lock nuts to lock the feed belt tensioning bolts in place.

Note: When tensioned properly the belt

should not lift off the table, slide back and forth, or slip.

DO NOT over-tension the feed belt, this may cause premature wearing of the belt, bushings, and cause strain on the motor.

Replacing the feed belt is a simple process, but will require tensioning and tracking when completed.

To replace the feed belt:

1. Disconnect power to the sander!

2. Use a permanent marker, paper correction

fluid, or fingernail polish to mark the front of the feed belt tensioning bolt (Figure 41) on both sides. This step will aid you in returning the bolts to their original position, reducing the amount of tracking necessary.

6. Clean any dirt or dust off of the table and rollers, have an assistant lift the table, then slide the new feed belt on.

7. Re-install and tighten all of the table cap screws.

8. Tighten the feed belt adjustment bolts equally, then follow the tensioning instructions on

Page 32.

Note: The feed belt will stretch slightly when

new and will need to be re-tensioned after a short amount of use.

9. Track the new feed belt according to the instructions on Page 31.

Note: One side of the belt may need to be

tighter than the other for the belt to track straight.

3. Loosen the lock nuts shown in Figure 41 and turn both of the feed belt adjustment bolts counterclockwise one full turn at a time to release the tension from the feed belt.

4. Remove the outside table cap screws shown in Figure 42 and loosen the corresponding cap screws on the inside edge.

The gauge blocks described here will be required to complete the remaining service procedures in this section.

To make the gauge blocks:

1. Edge joint the concave edge of the 2x4 flat on a jointer, as shown in Figure 43.

Figure 43. Edge jointing on a jointer.

2. Place the jointed edge of the 2x4 against the

table saw fence and rip cut just enough off the opposite side to square up the two edges of the 2x4, as shown in Figure 44.

Aligning the drums parallel to the conveyor belt (Figure 45) is critical for sanding accuracy. Care should be taken to make the tolerances as close as possible (within 0.002" from one side to the other) when adjusting the drum height.

3. Raise the table until the gauge blocks just touch the drum.

Pressure Plate

Note: A good way to know when they are

touching is to rock the drum back and forth while raising the table until you hear or feel contact with the gauge blocks.

4. Lower the table one full crank of the handwheel (taking handwheel free-play into consideration; or in other words, wait until the chain starts moving before starting to count the handwheel rotation).

5. Starting at one end, find the largest size feeler gauge that can pass between the drum and your gauge block. (The feeler gauge should slide with moderate resistance, without forcing the drum to roll.)

6. Repeat Step 5 at the other end of the drum.

—If the difference between the two sizes is

0.002" or less, then no adjustment is necessary.

When properly positioned, the pressure plates should be approximately 0.004" lower than the drum.

Adjusting the pressure plates is a fine balance between too much pressure and not enough. Too much pressure can cause problems like snipe or overloading the motor, not enough pressure may allow the workpiece to kick out of the sander towards the operator.

The pressure plates have been set correctly at the factory. Do not adjust the pressure plates unless absolutely necessary.

— If the difference between the two sizes is

more than 0.002", then one end must be adjusted to within 0.002" from the other. Continue to the next step.

7. Loosen the table cap screws and adjust the height of the table by rotating the adjustment knob shown in Figure 47.

To check pressure plate adjustment:

1. Disconnect power to the sander!

2. Place the gauge blocks on the feed belt as shown in Figure 46.

3. Raise the table until the gauge blocks just

touch the rear pressure plate.

4. Find the largest size feeler gauge that can pass between the drum and your gauge block. (The feeler gauge should slide with moderate resistance, without forcing the drum to roll.)

—If the gap is 0.004" (0.1mm) or less, then

no adjustment of the rear pressure plate is necessary.

— If the gap is more than 0.004" (0.1mm),

then the rear pressure plate must be adjusted.

5. Raise the table until the gauge blocks just touch the drum.

6. Find the largest size feeler gauge that can pass between the front pressure plate and your gauge block. (The feeler gauge should slide with moderate resistance, without forcing the drum to roll.)

—If the gap is 0.004" (0.1mm) or less, then

no adjustment of the front pressure plate is necessary.

— If the gap is more than 0.004" (0.1mm),

then the front pressure plate must be adjusted.

To adjust the rear pressure plate:

1. Disconnect power to the sander!

2. Loosen the lock nuts and tighten the cap

screws on both ends of the rear pressure plate shown in Figure 48 to raise the pressure plate, or loosen the cap screw to lower the pressure plate.

To adjust the front pressure plate:

1. Disconnect power to the sander!

2. Loosen the lock nuts and tighten the cap

screws on both ends of the front pressure plate shown in Figure 49 to raise the pressure plate, or loosen the cap screw to lower the pressure plate.

3. Adjust the front pressure plate until it is equal to, or up to 0.004" (0.1mm) lower than the height of the drum.
