Compound Mitre Cut - Ryobi RMS-1525 Operator's Manual

GB
• The bevel angle can be set from 0° to 45°.
• For your convenience, there is a double scale located on the mounting bracket. See Figure 26. If one side becomes
difficult to read as you lower the saw arm to the left, simply refer to the other side. Set the indicator at the desired angle,
on either side.
• Once the saw arm has been set to the required angle, tighten the bevel lock knob securely.
• Put the workpiece flat on the mitre table with one edge firmly against the fence. If the workpiece is warped,
put the convex side against the fence. If the concave side of a workpiece is put against the fence, the kerf could pinch
the blade and jam it near the end of the cut. See Figures 32 and 33.
• When cutting long pieces of wood or mouldings, support the far end of the workpiece on a stand or workbench level
with the mitre table.
• Align the cutting line on the workpiece with the saw blade.
• Hold the workpiece with one hand firmly against the fence. Use a vice or G-clamp to secure the workpiece whenever
possible. See Figure 27.
WARNING: To avoid serious personal injury, keep your hands outside the "keep hands clear" zone, at least 80 mm
from the blade. Never cut freehand (without holding the workpiece against the fence). The blade could jam in the
workpiece if it slips or twists.
• Before turning on the saw, try a dummy run to make sure that no problems will occur when the cut is made.
• Hold the saw handle firmly, press the lock button, then squeeze the trigger. Allow several seconds for the blade to reach
maximum speed.
• Slowly lower the blade down through the workpiece. See Figure 27.
• Release the trigger and allow the saw blade to stop rotating before raising the blade out of the workpiece. Wait until
the electric brake has stopped the blade turning before removing the workpiece from the mitre table.

COMPOUND MITRE CUT

A compound mitre cut is a mitre cut with a bevel. This type of cut is used for making picture frames, cutting mouldings, making
boxes with sloping sides and for cutting certain roofing timbers.
For compound mitre cuts, the control arm must be turned to the required angle and the saw arm must be tilted
to the required bevel angle. Care should always be taken when making compound mitre setups due to the interaction
of the two angle settings.
Adjustments of mitre and bevel settings are interdependent. When you adjust the mitre setting, you change the effect of
the bevel setting. Equally, when you adjust the bevel setting you change the effect of the mitre setting.
It may take several settings to obtain the required cut. The first angle setting should be checked after setting the second
angle, since adjusting the second angle affects the first.
Once the correct settings for a particular cut have been achieved, always make a test cut in an offcut before making
a final cut in the workpiece.
10.8 MAKING A COMPOUND MITRE CUT WITH YOUR MITRE SAW
• Pull out the locking pin and raise the saw arm fully.
• Loosen the bevel lock handle by turning the mitre lock handle approximately one-half turn to the left.
• Press the mitre lock plate down with your thumb and hold.
• Rotate the control arm until the pointer aligns with the desired angle on the mitre scale.
• Release the mitre lock plate.
Note: You can quickly locate 0°, 22.5°, 30°, and 45° left or right by releasing the lock plate as you rotate the control
arm. The lock plate will slot into one of the positive stops at the base of the mitre table.
• Tighten the mitre lock handle securely.
WARNING: To avoid serious personal injury, always tighten the mitre lock handle securely before making a cut.
If the mitre lock handle is not properly tightened, the control arm and mitre table may move during cutting.
• Loosen the bevel lock knob and tilt the saw arm to the left to the required angle.
• The bevel angle can be set from 0° to 45°.
• For your convenience there is a double scale located on the mounting bracket. See Figure 26. If one side becomes
difficult to read as you lower the saw arm to the left, simply refer to the other side.
Set the indicator at the desired angle, on either side.
• Once the saw arm has been set to the required angle, tighten the bevel lock knob securely.
• Recheck the mitre angle setting. Make a test cut in an offcut.
• Put the workpiece flat on the mitre table with one edge firmly against the fence. If the workpiece is warped,
put the convex side against the fence. If the concave side of a workpiece is put against the fence, the kerf could pinch
the blade and jam it near the end of the cut. See Figures 32 and 33.
