Ryobi P550 manual To Compound Miter CUT

OPERATION

nGrasp the stock firmly with one hand and secure it against the fence. Use the optional work clamp or a C-clamp to secure the workpiece when possible. See Figure 36.

nBefore turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made.

nGrasp the saw handle firmly, depress the switch lock, then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.

nSlowly lower the blade into and through the workpiece.

nRelease the switch trigger and allow the saw blade to stop rotating before raising the blade out of workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from miter table.

TO COMPOUND MITER CUT

See Figure 37.

A compound miter cut is a cut made using a miter angle and a bevel angle at the same time. This type of cut is used to make picture frames, cut molding, make boxes with sloping sides, and for certain roof framing cuts.

To make this type of cut the control arm on the miter table must be rotated to the correct angle and the saw arm must be tilted to the correct bevel angle. Care should always be taken when making compound miter setups due to the interaction of the two angle settings.

Adjustments of miter and bevel settings are interdependent with one another. Each time you adjust the miter setting you change the effect of the bevel setting. Also, each time you adjust the bevel setting you change the effect of the miter setting.

It may take several settings to obtain the desired cut. The first angle setting should be checked after setting the second angle, since adjusting the second angle affects the first.

Once the two correct settings for a particular cut have been obtained, always make a test cut in scrap material before making a finish cut in good material.

nPull out the lock pin and lift saw arm to its full height.

nLift the miter table clamp.

�n Rotate the miter table until the pointer aligns with zero on the miter scale.

�n Push the miter table clamp down to lock.

NOTE: You can quickly locate 0˚, 15˚, 22-1/2˚, left or right, 30˚ and 45˚ left or right by releasing the miter lock plate as you rotate the control arm. The miter lock plate will seat itself in one of the positive stop notches, located in miter table frame.

nLoosen the bevel lock knob and move the saw arm to the left to the desired bevel angle.

nBevel angles can be set from 0˚ to 45˚.

nOnce the saw arm has been set at the desired angle, securely tighten the bevel lock knob.

nRecheck miter angle setting. Make a test cut in scrap material.

nPlace the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade. See Figures 41 - 42.

nWhen cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table. See Figure 38.

nAlign the cutting line on the workpiece with the edge of saw blade.
