Operation; Connecting To A Dust Collector - King Industrial KC-12HJPC Instruction Manual

CONNECTING TO A DUST COLLECTOR

This machine is equipped with a dust chute for use during jointing and planing
operations. The dust chute (A) Fig.22 has a 4" opening. It's very important to use
some type of dust collection system with this machine to prevent the build up of
wood chips that could interfere with the rollers or the cutterhead. Attach an
appropriate 4" diameter hose (B) (not supplied) to the dust chute and secure it in
place using a wire clamp (not supplied).
USING THE MACHINE IN JOINTER MODE
Operator Positioning: The operator should be positioned offset behind the infeed
table, as shown in Fig.23. The workpiece is fed through the jointer from the right
side of the machine to the left.
Hand Placement: Never allow your hands to pass over the cutterhead. At the
beginning of the cut, place both hands on the workpiece, with the left hand holding
the workpiece against the infeed table, and the right hand pushing it against the
fence. Slowly slide the workpiece toward the cutterhead. As the workpiece moves
across the cutterhead, the left hand will move to the outfeed table side of the
workpiece without passing directly over the cutterhead. As the end of the
workpiece approaches the cutterhead, the right hand will move to the outfeed table
side of the workpiece to finish the cut.
Surfacing: The jointer can be used to produce a flat, even surface on the
workpiece. The other side can then be fed through a planer to achieve two
perfectly flat and parallel surfaces. Tips for surfacing:
1. If the wood is bowed, place the concave side down and make small cuts until
the surface is flat.
2. Never use a workpiece that is shorter than 12" without using a special workpiece
holding fixture.
3. Use a push block on workpieces that are thinner than 3".
4. Making small cuts incrementally is recommended. Cuts of approximately 1/16" at
a time will produce the best results.
Direction of Grain: Always feed the workpiece with the grain when possible, and avoid feeding a workpiece through against the grain. Feed-
ing against the grain could result in chipped or uneven surfaces.
Jointing: Jointing produces a flat edge surface that is suitable for joinery, finishing, or ripping stock on a table saw.
Safety instructions for jointing:
1. Always use a push block for workpieces less than 3" wide, less than 1/4" thick, or 12" long.
2. Adjust the fence so that only the width of the cutterhead being used for jointing is exposed.
3. Ensure that long workpieces are properly supported on both infeed and outfeed sides.
Jointing a Workpiece:
1. Use a square to set the fence at 90°.
2. Ensure the workpiece is appropriate for jointing, and determine the direction of the grain.
3. If the wood is bowed, place the concave side down.
4. Pass the workpiece across the cutterhead, making small cuts of approximately 1/16" until the surface is flat.
beveling: The jointer can be used to create a beveled edge. Use a bevel gauge to set the desired angle and adjust the fence by tilting it
accordingly. Follow the same steps as used in the section "Jointing". Make small cuts, and several passes to achieve the desired bevel.
USING THE MACHINE IN PLANER MODE
Thickness Planing: Thickness planing refers to feeding the workpiece through the planer until the desired thickness is achieved. Tips for
thickness planing:
1. Depth of cut will have a big impact on the quality and results of thickness planing.
2. Setting the depth of cut will depend on the workpiece material, width, grain direction, dryness, etc.
3. The maximum recommended depth of cut for a single pass is 1/8" for planing operations on a workpiece up to 5-1/2" wide. The maximum
depth of cut for a single pass of wider workpieces up to 12" is 1/16".
4. Using a depth of cut less than 1/16" will produce the best results.
5. Plane the workpiece repeatedly, taking off a small amount with each pass. Once the workpiece has one level side, flip the workpiece to
plane the other side. Alternate sides of the workpiece with each pass until the desired thickness has been achieved.
