Black & Decker BT1800, 90544326 manual Machine USE, Changing the Blade, Cross-Cutting

CHANGING THE BLADE

DISCONNECT MACHINE FROM POWER SOURCE.

Use only 10” diameter saw blades rated for 4700 RPM or higher. Use only saw blades with 5/8” arbor holes.

1.Raise the saw blade to its maximum height and remove the table insert (A) Fig. 38.

2.Place a piece of wood (B) Fig. 38 flat on the table against the blade so that a tooth of the blade can “grab” the wood to keep the blade from turning. Remove the arbor nut (C) with the blade removal wrench (D). Turn the nut (C) counter-clockwise to remove. Remove the outside blade flange (E) and saw blade (F).

3.Reverse the procedure to install the new blade.

MACHINE USE

Common sawing operations include ripping and crosscutting plus a few other standard operations of a fundamental nature. As with all power machines, there is a certain amount of hazard involved with the operation and use of the machine. Using the machine with the respect and caution demanded as far as safety precautions are concerned, will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or completely ignored, personal injury to the operator can result. The following information describes the safe and proper method for performing the most common sawing operations.

THE USE OF ATTACHMENTS AND ACCESSORIES NOT RECOMMENDED BY BLACK & DECKER MAY RESULT IN THE RISK OF INJURY TO THE USER OR OTHERS.

CROSS-CUTTING

Cross-cutting requires the use of the miter gauge to position and guide the work. Place the work against the miter gauge and advance both the gauge and work toward the saw blade, as shown in Fig. 39. The miter gauge may be used in either table slot. When bevel cutting (blade tilted), use the table groove that does not cause interference of your hand or miter gauge with the saw blade guard.

Start the cut slowly and hold the work firmly against the miter gauge and the table. One of the rules in running a saw is that you never hang onto or touch a free piece of work. Hold the supported piece, not the free piece that is cut off. The feed in cross-cutting continues until the work is cut in two, and the miter gauge and work are pulled back to the starting point. Before pulling the work back, it is good practice to give the work a little sideways shift to move the work slightly away from the saw blade. Never pick up any short length of free work from the table while the saw is running. Never touch a cut-off piece unless it is at least a foot long.

For added safety and convenience the miter gauge (A) can be fitted with an auxiliary wood-facing (B), as shown in Fig. 39A, that should be at least 1 inch higher than the maximum depth of cut, and should extend out 12 inches or more to one side or the other depending on which miter gauge slot is being used. This auxiliary woodfacing (B) can be fastened to the front of the miter gauge by using two wood screws (C) through the holes provided in the miter gauge body and into the woodfacing.

NEVER USE THE FENCE AS A CUT-OFF GAUGE WHEN CROSS CUTTING.

When cross-cutting a number of pieces to the same length, a block of wood (B) Fig. 39B can be clamped to the fence and used as a cut-off gauge as shown in Fig. 39B. It is important that this block of wood always be positioned in front of the saw blade as shown. Once the cut-off length is determined, secure the fence and use the miter gauge to feed the work into the cut. This block of wood allows the cut-off piece to move freely along the table surface without binding between the fence and the saw blade, thereby lessening the possibility of kickback and injury to the operator.

WHEN USING THE BLOCK (B) FIG. 39B, AS A CUT-OFF GAUGE , IT IS VERY IMPORTANT THAT THE REAR END OF THE BLOCK BE POSITIONED SO THE WORK PIECE IS CLEAR OF THE BLOCK BEFORE IT CONTACTS THE BLADE.
