saw _lode cuts through the work_

The carriage will tend to move toward the operator so be

,prepared to restrain it by keeping your arm straight from fife shoulder to the wrist, When the cut is complete, the saw should be returned to the back of the radial arm and the

swltch key turned "Off". it will be noticed, that the saw blade tends to feed itself through the work due to the rotation of the blade and the direction of feed. Therefore, the operator should develop the habit

of holding his right arm straight from the shoulder to the wrlst_ After this method is used a few times the oper-

ator will find that it is necessary to roll or rotate the body

from the waist up. If this method is followed, it will become

apparent that very little effort is required on the pert of the

operator to move the saw blade through the work, and in most cases, the right arm is used merely to control the rate of

feed of the saw through the board_ It will also be found that when cross-cuttlnga thick board it wilt be necessary to retard movement of the saw through the work. By holding the right arm (right hand normally grips the saw handle) _alght, the

operator can easily control the rate of feed, thus prever_ing the saw blade from overfeeding and stalling the saw motor.

This must be avoided whenever possible. In some casesit may

become necessary to cross-cut tong boards which extend over the saw table on one, or both sides. This can cause

buckling of the board and bind the sow during the cut, To eliminate th;s condition the ends of the board should be sup-

ported. Figure 27 illustrates a typical support which can be made and used to facilitate cross<utting of long lumber°

RIPPING

Ripping is the sawing of wood with the grain. It is always done with the help of the fence as a guide to position and maintain the work at the correct width for the cut_ Because the work is pushed along the fence, it must have a reason..

ably straight edge to make sliding contact with the fence° Also, the work must make solid contact wlth the table sa that it will not wobble or rock. Provide a straight edge, even if this means temporary nailing of an auxiliary straight edge board to the work_ If work piece is warped, torn the hollow side down.

Use of the sow guard is always recommended; and the arrti- kicEback paw! assembly shoud always be used in both in-rip

or our-ripoperations, Before ripping and after the saw has been positioned prior to cutting, the saw guard and anti- kickback pawl assembly must be properly adjusted_ Loosen the wing nut holding the guard to the motor and lower the

nose of the guard to within _" above the top surface of

the board to be cu_. Refighten the wing n_ securely.

CAUTION

The nose of the guard refers to that end of the guard which is opposite to the end which mounts the anti-kickback pawl assembly. Always rlp from the nose of the guard. See Warning [.abel on guard.

F;gure 27 Figure

At the opposite end of the guard, loosen the wing screw holding the anti-kickback pawl assembty and lower the assembly until the tips of the pawls are 7/8" below the top _Jrface of the board to be cu/_ Retighten the wing screw

IN-RIPPING--In-riprefers to a posltion when the blade is between the motor and the fence and parallel to the fence. See Figure 28. To place the sow in this position, unlock the yoke, disengage the swivel latch pin and rotate the yoke 90 ° clockwise (viewing it from the carriage) until the swivel latch pin automatically indexes the yoke 90% Relock the yoke. See "'Adjustmentof Pointers" to check accuracy of "lnoRip" scale reading. Position the motor on the radial arm until the pointer on the "In-Rip" scale indicates the desired width of the finished cut board_ Tighten the carriage lock knob se- curely. Position the discharge elbow on the guard _o that sawdust will be blown toward the rear of the saw. Turn the saw "'On"end lower the saw blade until it cuts into the table top about 1/32",, Turn the saw "Off"° Haw adjust the saw guard and anti.kickback pawl assembly as described

in the paragraph "Ripping". The board to be ripped must be fed into the saw blade from the right side of

the table, therefore, the normal position for the operator

is also at the right side of the table. With the left hand safely clear of the blade and holding the board to be ripped down

against the table and against the face of the fence as a guide, use the right hand to feed the board into the saw. The left hand should remain stationary, serving as a guide only. As the right hand approaches the left hand, hold a push stick with the right hand to complete the cut°Do not leave a long board unsupported so that the spring of the board causes it to shift on the table_ A support like that described in "Cross_ Cutting" can be used to support the board behind the blade; and if the board is very long, use another support in front of the saw° R_pped boards up to 8_" wide can be cut in

the In-Ripposltiom

OUT-RIPPING-_Ouf_rip refers to a position when the motor is between the blade and the fence° Normally, this position is only used when the width of the required ripped board cannot be cut from the in-rip position. Ripped boards up to 181,_°'wide can be cut in the out_rlp position when the fence is against the front table. If the fence is moved to the extreme rear position against the table clamps, ripped boards up to 25,%" wide can be cut_ To place the saw in the out.rip position, the yoke must be rotated and indexed 90 ° counterclockwise from the crossocutposition and locked.. The same procedure far sawing is used except that now the operator stands at the left side of the table and a push stick is normally nat required°

NOTE

For added table space in front of the blade see "Movement and Position of the Yoke".
