QUICk OPERATIONS CHECkLIST
Before using the saw each time, verify the following:
1, The blade is tight.
2. The bevel angle and height lock-knobs are tight.
3. If ripping, ensure that the fence lock lever is tight and that the fence is parallel to the blade.
4. If crosscutting, ensure that the miter gauge knob is tight.
5. Proper eye, hearing, and respiratory equipment are being used.
6. The blade guard is properly attached and the anti-kickback pawls are functioning.
Failure to adhere to these common safety rules can greatly increase the likelihood of injury.
BLAdE gUARd ANd SPLITTER USE
The blade guard assembly provided with
delta saws (Fig. 52) must be used for all through-sawing
operations. The splitter prevents the kerf from closing and
binding the blade, causing kickback. The anti-kickback pawls
(A) Fig. 52 prevent the workpiece and the cut-off piece from
being thrown back at the operator. The guard prevents dust
and debris from being thrown at the operator. To use the guard
properly:
1. Make sure that the splitter is aligned with the blade
as described in the section "BLAdE gUARd ANd
SPLITTER ASSEMBLY ANd ALIgNMENT."
2. Replace or sharpen the anti-kickback pawls when they
become dull.
3. Keep the guard clean.
4. Use caution when feeding workpieces that may catch
on the guard and cause a bind, or force the guard into
the blade (such as when cutting moulding).
CROSS-CUTTINg
Cross-cutting requires the use of the miter gauge to posi tion and guide the work. Before starting the cut, raise the blade so that
it is about 1/8" (3.2mm) higher than the top of the workpiece. Place the work against the miter gauge and advance both the
gauge and work toward the saw blade (Fig. 53). You can use the miter gauge in either table slot. Start the cut slowly and hold
the work firmly against the miter gauge and the table. Keep both hands on the miter gauge and workpiece. Do not touch the
cut-off piece. Feed the workpiece steadily through the blade until the workpiece is completely cut. Shift the workpiece slightly
sideways away from the blade, then pull the workpiece and miter gauge back to the starting position. Remove the workpiece,
then use a push stick to push the cut-off piece past the blade and off the table before beginning the next cut.
For added safety and convenience, you can attach an auxiliary wood-facing (C) Fig. 54 to the miter gauge. This facing should
be at least 1" higher than the maximum depth of cut, and should extend out 12" or more to one side or the other depending
on which miter gauge slot is used. Attach this auxiliary wood-facing (C) to the front of the miter gauge by using two wood
screws with a washer through the slots provided in the miter gauge body.
