Ripping (Fig. A, B, S, T)

WARNING: Sharpedges.
1. Set the blade to bevel 0°.
2. Install the rip fence and lock the rip fence latch
18
(Fig.A).
3. Raise the blade until it is about 3 mm higher than the
top of the workpiece. Install upper blade guard and anti-
kickbackassembly.
4. Adjust the position of the fence and lock the rail lock
lever
5
, refer to Rip FenceOperation.
5. Hold the workpiece flat on the table and against the fence.
Keep the workpiece away from theblade.
6. Keep both hands away from the path of the blade(Fig.S).
7. Switch the machine on and allow the blade to reach
fullspeed.
8. Slowly feed the workpiece underneath the guard, keeping
it firmly pressed against the rip fence. Allow the teeth to
cut, and do not force the workpiece through the blade. The
blade speed should be keptconstant.
9. Always use a push stick
21
when working close to the
blade(Fig.T).
10. After completing the cut, switch the machine off, allow the
blade to stop and remove theworkpiece.

WARNING:
• Never push or hold the "free" or cut-off-side of
theworkpiece.
• Do not cut excessively smallworkpieces.
• Always use a push stick when ripping
smallworkpieces.
Bevel Cuts (Fig. A)
1. To set the required bevel angle, rotate the bevel lock
lever
7
by pushing it up and to theright.
2. To set to desired angle, rotate the lever by pushing it down
and to the left to lock inplace.
3. Proceed as forripping.
Cross-Cutting and Bevel Crosscutting (Fig. S)
1. Remove the rip fence and install the mitre gauge in the
desiredslot.
2. Lock the mitre gauge at 0°.
3. Proceed as forripping.
Mitre Cuts (Fig. A)
1. Set the mitre gauge
10
to the requiredangle.
NOTE: Always hold the workpiece tightly against the face of the
mitregauge.
2. Proceed as forripping.
Compound Mitre
This cut is a combination of a mitre and a bevel cut. Set the
bevel to the angle required and proceed as for a cross-cutmitre.
Support for Long Pieces
• Always support longpieces.
• Support long workpieces using any convenient means
such as saw-horses or similar devices to keep the ends
fromdropping.
Non-Through-Cutting
(Grooving and Rabbeting)

WARNING: Remove the blade guard assembly
11
and
install the non-through-cutting riving knife
52
for non-
through-cutting operations. Use featherboards for all
non-through-cutting operations where the blade guard
assembly, anti-kickback assembly and riving kife cannot
beused.
Instructions in the Ripping, Crosscutting, Bevel Crosscutting,
Mitreing, and Compound Mitreing sections are for cuts
made through the full thickness of the material. The saw can
also perform non-through cuts to form grooves or rabbets in
thematerial.
Non-Through-Ripping (Fig. D, X)

WARNING: A rip fence should ALWAYS be used for
ripping operations to prevent loss of control and personal
injury. NEVER perform a ripping operation freehand.
ALWAYS lock the fence to therail.

WARNING: When bevel ripping and whenever possible,
place the fence on the side of the blade so that the blade is
tilted away from the fence andhands.

WARNING: Keep hands clear of theblade. With non-
through-cutting the blade is not always visible during the
cut, so increased caution is necessary to ensure hands are
clear of theblade.

WARNING: Use a push stick to feed the workpiece if there
are 51–152mm between the fence and the blade. Use a
narrow ripping fence feature and push block to feed the
workpiece if there are 51mm or narrower between the
fence and theblade.
1. Remove the blade guard assembly
11
and install the non-
through-cutting riving knife
52
(Fig. D). Refer to: Mounting
the Blade Guard Assembly/RivingKnife.
2. Lock the rip fence by pressing the rail lock lever down.
Remove the mitregauge.
3. Raise the blade to the desired cutdepth.
4. Hold the workpiece flat on the table and against the fence.
Keep the workpiece about 25.4mm away from theblade.

WARNING: The workpiece must have a straight edge
against the fence and must not be warped, twisted or
bowed. Keep both hands away from the blade and away
from the path of the blade. See proper hand position in
FigureU.
5. Turn the saw on and allow the blade to come up to speed.
Both hands can be used in starting the cut. When there
are approximately 305mm left to be ripped, use only one
hand, with your thumb pushing the material, your index and
second finger holding the material down and your other
