1. Carriage lock knob must be locked.
2. Radial arm must be locked in 0° position.

When rippir g stock 2 inches or !ess between the blade
and feuce (guide) use an Auxiliary Fence and Push
Block. Make these work helpers to the dimensions
shown,
Make the Auxiliary Fence using a piece of 3!8 in. and
3/4 in, plywood. Fasten together with glue and nails.
Make the Push Block using a piece of 3/8 in. and 3/4
in. plywood,
NOTE: Since the Push Block is used with the Auxiliary
Fence, the 4-3/4 in. dimensions must be held identical
on both the pieces.
The small piece of wood 3/8 in. x 3/8 in. x 2-1/2 in.
should be GLUED to the plywood... DO NOT USE
NAILS. This is to prevent dulling the sawbtade in the
event you f_istakirlgly cut into the push block.
Position th_ handle in the center of the plywood and
fasten together with glue and woodscrews.
The push hlock should feed the stock being ripped
until the stock is clear of the rear of the blade, and
then pulled r_ack with use of the grip,
Hands mHst be kept well away from saw blade.
9. Saw blade MUST be parallel to fence, to nTininlize
possibility of kickbacks.
10. When ripping narrower than 3/8 in, position the
sawblade to remove the narrow strip from edge of
workpiece furthest from the fence. Follow procedures
as above based on distance from blade to fence.

OPERATION No. 5 -- OUT-RIPPING
AND IN-RIPPING
Ripping is the prqcess of sawing the workpiece by
feeding it into the saw blade when using the fence as a
guide and as a positioning device to obtain the desired
width of cut The sawbtade is parallel to the fence.
WARNING: NEVER RIP FREE-HAND. BEFORE
RIPPING, MAKE SURE THE GUARD, AND
ANTIKICKBACK AND SPREADER ASSEMBLY ARE
SET UP PROPERLY. ALSO, MAKE SURE THE SAW
BLADE IS PARALLEL WITH THE FENCE. NEVER
RIP WORKPIECES SHORTER THAN THE SAW
BLADE DIAMETER.
