Site Considerations Weight Load The Model G9953 16" Ultimate Series Jointers and the Model G4815 20" Ultimate Series Jointer represent a large weight load. Most shop floors should be sufficient to carry the weight of the machine. Reinforce the floor if you question its ability to support the weight.
Beginning Assembly This section will cover the basic assembly and adjustment instructions needed to begin opera- tion. Complete the assembly in the order provid- ed in this manual and then read the remaining portion of the manual before attempting any type of operation.
Pedestal Switch To mount the pedestal switch: Attach the pedestal switch (Figure 13) to the back of the base with (4) M10-1.5 x 25 cap screws and (4) M10 flat washers . Figure 13. Attaching pedestal switch. Ultimate Series Jointers To attach dust collection hose to the dust port: Attach a 5"...
NOTICE The remaining instructions in this section cover factory settings which should already be adjusted correctly; however, we recommend checking the settings to be sure they were not bumped out of adjust- ment during the shipping process. If it is determined that a setting is out of correct adjustment, please refer to Section 8: Service Adjustments.
Carbide Cutter To Outfeed Table Alignment (Models G9953ZX, G9953ZXF and G4815) The outfeed table must be perfectly level with the carbide cutters. Note—You only need to verify the outfeed table height with one of the carbide cutters. To verify the factory setting:...
Infeed Table To Outfeed Table Alignment NOTICE Review the "Knife To Outfeed Table Alignment" and the "Carbide Cutter To Outfeed Table Alignment" sub-sections on the previous pages before continuing. The surface of the infeed table must be perfectly level with the surface of the outfeed table. To verify the factory setting: 1.

Start Up Serious personal injury could result if the machine is connected to the power source during assembly or adjustment. Wait until the machine is turned off, unplugged and all working parts have come to a complete stop before attempting to assemble or adjust the machine! Loose hair and clothing could get caught in...
SECTION 6: OPERATIONS Operation Safety Your safety is important! Please follow the warnings below during this entire section: To avoid serious personal injury, read and become familiar with the entire instruction manual before using the jointer. Damage to your eyes, lungs, and ears could result from failure to wear safety glasses, a dust mask, and hearing protec- tion while using with this machine.
• Remove foreign objects from the stock. Make sure that any stock you process with the jointer is clean and free of any dirt, nails, staples, tiny rocks or any other foreign objects that may damage the jointer blades. • Only process natural wood fiber through your jointer.
Surface Planing The purpose of surface planing on the jointer is to make one flat face on a piece of stock (Figure 30) to prepare it for surface planing on a thick- ness planer. Figure 30. Illustration of surface planing results. NOTICE If you are not experienced with a jointer, set the depth of cut to 0", and practice feeding...
Edge Jointing The purpose of edge jointing is to produce a fin- ished, flat-edged surface (Figure 31) that is suit- able for joinery or finishing. It is also a necessary step in the squaring process of rough or warped stock. Figure 31.
Bevel Cutting The purpose of bevel cutting is to cut a specific angle into the edge of a workpiece (Figure 32). The Ultimate Series Jointers have preset fence stops at 45˚ to the left and 45˚ to the right. If your situation requires a different angle, the preset fence stops can be easily adjusted for your needs.
SECTION 7: MAINTENANCE Maintenance Safety Your safety is important! Please follow the warnings below during this entire section: Disconnect power to the machine when perform- assembly ments. Failure to do this may result in serious per- sonal injury. Loose hair and clothing could get caught in machinery and cause serious personal injury.
Carbide Cutters (Models G9953ZX, G9953ZXF and G4815) The carbide cutters are typically rotated at the same time when they become dull; however, the cutters can also be rotated individually when one becomes nicked or damaged.
SECTION 8: SERVICE ADJUSTMENTS Adjustment Safety Your safety is important! Please follow the warnings below during this entire section: Disconnect power to the machine when perform- assembly ments. Failure to do this may result in serious per- sonal injury. Loose hair and clothing could get caught in machinery and cause serious personal injury.
Knives (Model G9953 Only) Setting the knives correctly is crucial to the prop- er operation of the jointer and is very important in keeping the knives sharp. If one knife is higher than the others, it will do the majority of the work, and thus, dull much faster than the others.
12. Repeat step 10, but final tighten each gib bolt. Ultimate Series Jointers Carbide Cutters (Models G9953ZX, G9953ZXF and G4815) The dot on each cutter is used as a reference point when determining which cutter edges are used, or dull, and which are sharp. Be sure to...
4. Sparingly oil the threads of the carbide cutter Torx® screws with a light machine oil. 5. Adjust the compressor air pressure to 30 PSI. Note—The low pressure (torque) setting will reduce the chance of cross threading the Torx® screw threads as well as seat the car- bide cutters correctly.

2. Remove the two hex bolts and flat washers that secure the back eccentric cover behind the infeed table. Carefully remove the back eccentric cover and set it aside. 3. Using a 4mm Allen wrench, loosen the set screw located on the side of each eccentric (Figure 39).
Fence Stops To set the 90˚ stop: Place a square on the outfeed table fairly close to the cutterhead as shown in Figure Figure 41. Use of square to align fence. While holding the fence adjusting handle, loosen the check nut on the 90˚ stop screw (Figure 42).
Depth-Of-Cut Scale The depth-of-cut scale indicates the amount of material that will be removed with each pass over the jointer. To set the depth-of-cut scale: Unplug the machine from the power source! Open the access door on the back of the machine, just below the fence adjustments.
