Cross-Cutting, Preliminary CROSS-CUT AT Position

STANDARD SAW OPERATIONS

PRELIMINARY CROSS-CUT AT THE

0 ° POSITION

1.Loosen the carriage lock knob (4, figure 23) and move

the carriage to position the saw just forward of the rip fence (See figure 22.)

2.Lower the radial arm until the saw blade just clears the table top.

3.Tighten the carriage lock knob (4, figure 23.)

CAUTION: Before making the cut, make sure the arm latch handle (8, figure 23) is fully en- gaged in the detent notch.

4.Plug in the power cord (if not already connected).

5.Insert the safety lock key (figure 24) and pull the switch lever out to "ON" position.

6.Lower the radial arm, by rotating the elevation crank, until the saw blade cuts into the table top surface to a depth of approximately 1/32-inch.

7.Complete the blade clearance groove in the table and rip fence as follows:

a.Grasp the handle (14, figure 23) with the left hand and loosen the carriage lock knob (4, figure 23) with the right hand.

b.Slowly pull the carriage with the right hand out to the extreme end of its travel.

c.Push the carriage slowly rearward to the extreme end of the travel. This stroke will cut through the

rip fence.

d.Push the switch to "'OFF" position.

CROSS-CUTTING

Cross-cuttingis the sawing of wood across the grain. Boards are sawed with the grain running the length of the board. If a straight cross-cut is desired, the board is placed on the saw table against the fence so that the grain is parallel to the fence. (See figure 30.)

CAUTION: Make sure the guard chute is in the

maximum raised position before turning on the motor.

NOTE: When cross-cutting normal pieces of lumber, the long end of the board should be

placed to the left of the saw blade, as the board is normally held by the left hand during the sawing operation.

1.The radial arm'must be positioned at 0 ° as indicated by the radial arm position indicator. The arm latch handle must be indexed and arm lock handle tightened. (Refer

to paragraph entitled "Angular Movement and Locking of the Radial Arm".)

2.The yoke must be indexed at the 0 ° position, making the saw blade perpendicular to the rip fence, and the yoke clamp arm placed in locked position.

3.The motor must be positioned at 0 °, as indicated by the bevel scale, and locked.

4.Turn the elevation crank to lower the saw until the blade teeth are approximately 1/32 prbelow the table surface and ride in the saw slot made when performing the

"PRELIMINARY CROSS-CUT AT THE 0 ° POSITION".

5.Push the saw carriage to the rear of the radial arm so the blade is behind the rip fence.

6.Adjust the anti-kickback pawl assembly so it clears the board to be cut.

7.Turn the switch key "ON'" and pull out the switch lever to start the saw motor.

8.Hold the board firmly against the rip fence with the left hand and grasp the handle with the right hand.

9.The cut is then made by pulling the carriage forward until saw blade cuts through the work. When the cut is complete, the saw should be returned to the back of the radial arm and the switch turned "OFF". When more experience is gained by using the saw, it will be noticed that when pulling the saw forward dur- ing cross-cutting, 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 wrist. After using this method a few times, the operator will find that it is necessary to roll or rotate the body from the waist up. It will soon become apparent that very little effort is required to move the saw blade through the work, and in most cases, the right arm is used merely to control the rate of feed. It will also be discovered that when cross-cutting a thick board, movement of the saw through the work must be retarded. By holding the right arm /right hand normally grips the saw handle) straight, the operator can easily control the rate of feed, thus preventing the saw blade from overfeeding and stalling the saw motor, which must be avoided whenever pos-
