collection port. Secure a 4-inch dust collection hose (not provided) to the port with a hose clamp (see Figure 5-2). Connect to a high volume dust collector, minimum 400 CFM. Note: Dryer vent hose is not acceptable for this purpose. Read and understand the entire contents of this manual before attempting set-up or operation. Failure to comply may cause serious injury.

The tapered edge of strip end should follow as closely as possible to edge of drum. 6.0 Electrical connections 5. Continue to wrap abrasive in spiral fashion by rotating drum with one hand and guiding strip with the other. See Figure 5-5. All electrical connections must be done by a qualified electrician in compliance with all local codes and ordinances.
depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Failure to comply may cause serious or fatal injury.
1. Make sure proper belt tension has been achieved (sect. 7.3.1). 2. Turn on conveyor and set to maximum speed. Watch for tendency of conveyor belt to drift to one side of conveyor. 3. If conveyor drifts, slightly loosen two screws (A, Figure 7-2) and turn take-up screw (B, Figure 72) on one side of conveyor as needed. Note: Adjust take-up screw only 1/4-turn at a time. Allow time for belt to react to adjustments before proceeding further. 4. Figure 7-1: depth scale adjustment 7.

If drum does not contact gauge equally on both ends of drum, alignment is needed. 7.4.1 Performing drum alignment Tension roller pressure may be increased or decreased by turning the screws on the tension roller brackets (Figure 7-4) at each end of drum.. To align conveyor table with drum: 1. Loosen both table locking screws (C, Figure 73) with 5mm hex wrench. Loosen both table locking screws before adjusting drum alignment.
8.2 Switch safety key 8.5 Establishing drum height To prevent unauthorized use of sander, turn off main switch and pull out safety key (Figure 8-1). Store key in a safe place. Key must be reinserted to start sander. A good rule of thumb when sanding with grits finer than 80: 1. To establish drum height, position stock under the drum. Do NOT start drum. 2. Lower drum to the stock thickness, making sure drum can still be rotated by hand while just contacting stock.
8.6 Maximum performance tips 8.6.5 Sanding imperfect stock The versatility designed into the JWDS-series drum sander allows it to be used for a variety of tasks that will boost return on your investment. For example, it will speed up fine sanding work often done with slower, dust-generating hand sanders, and will achieve fine thickness adjustments not possible on some sanders. It can be used to surface figured woods – bird’s eye or curly maple, for example – which can be damaged if fed through a planer.
9.0 User-maintenance Before doing maintenance on the machine, disconnect it from the electrical supply (pull out the plug), unless indicated otherwise. Failure to comply may cause serious injury. 2. Loosen two screws on the coupling (D, Figure 9-2). 3. Carefully slide drum out of coupling and remove from machine. 9.1 Cleaning and lubrication For best results, make cleaning the sander a regular shop procedure.
Note: If conveyor belt continually tracks to one side of the machine, reversing the belt on the conveyor table may remedy the problem. To make sure the conveyor table is not twisted, place a level on the conveyor table. Level the machine if needed. If there is still a problem, proceed with the steps below: 4. Step 1: Check conveyor drive roller and driven roller to make sure they are parallel to surface of conveyor table. To do this, first center conveyor belt on the conveyor table.
Note: Grits that are too fine can sometimes burnish the wood and leave a glossy surface which will not accept stains evenly. This will vary by type of wood. Oak, for example, is susceptible to burnishing because of its open pores. 10.0 Abrasives The abrasive material you choose will have a substantial effect on the performance of your sander. Variations in paper type, weight, coating and durability all contribute to achieving your desired finish. 10.
