3, Drill two holes in table at marked locations. Holes in saw
base are 7/16-inch in diameter. It is recommended that
3/8-inch bolts be used for mounting.
4. Cut an opening in the table top undersawbase, in order
to prevent accumulation of sawdust inside the base. The
opening should be at least 12-inches, The actual size
will depend upon the type of table or bench being used.
5. Mount the saw with proper length bolts.
PERIODIC MAINTENANCE OPERATIONS
This Craftsman saw is a fine machine and should be given
the best of care. If kept clean andproperly lubricated, it
will provide many years of trouble-free service. There are
no specific maintenance time tables. However, operations
listed and described in paragraphs immediately following
should be performed when conditions or symptomssuggest
need for attention.
1. Removing Saw Blade.
NOTE: The saw blade, regardless of type
being used, should be kept sharp at all times.
Accurate and effective work cannot be
achieved with a dull blade. The saw arbor
has right-hand threads which causes the
arbor nut to become tighter in response to
saw rotation.
a. Remove the table insert, as described under "'Assem-
bly and Adjustments".
b. Slide a wedge shaped block of wood under a saw
tooth to wedge the blade and prevent rotation. CSee
figure 50.)
c. Using the arbor wrench supplied with the saw, rotate
the arbor nut counterclockwise to loosen it Remove
the nut and loose collar with fingers.
d. Remove the wood block and slide saw blade off the
arbor shaft.
2. Installing Saw Blade.
CAUTmON: Under no circumstances should a
blade with a diameter greater than 10 inches
be used with this saw.
ARBO_ WRENCH
WOOD BLOCK
a. Slide the new blade on arbor shaft, making sure saw
teeth are "'pointing'* toward the front of saw table.
install the loose collar and arbor nut finger tight.
b. Insert the wedge shaped wood block into the table
opening at the rear of saw blade and tighten the
arbor nut with the arbor wrench supplied wlth the
saw. (See figure 51.1 Remove the wood block.
c. install the table insert as described under "Assembly
and Adjustments".
3. Lubricate Saw When Needed.
Lubricant should be applied to friction points when they
appear dry upon visual inspection,or when friction increases
on the various controls.

a_ The tilt and lift screws are self-cleaning, which pre-
ventsclogging or gummingof the threads, as the sharp
threads w_pe and clean the gear teeth. Apply a few
drops of SAE 20 or 30 oil as needed to keep parts
rotating smoothly.
b. The saw arbor bearings have been packed at the
factory with proper lubricant and require no addi-
tional lubrication. Other parts requiring lubrication
should be oiled frequently with SAE No. 20 or 30 o I.
The following parts should be lubricated regularly:
(1) Table trunnions.
(2) Lift screw and gear rack of assembled arbor.
WOOD BLOCK
(3) Tilt screw block, tilt screw threads and tilt nut.
(4) Pivot pin and saw arbor housing guide.
(5) Clamp screw.
c. All points where a slip fit is necessary for adjustment
purposes should be oiled occasionally. (Pivot arm
screw, for example, figure 46.)
d. Attention should be given to moving parts in the rip
fence and miter gauge for cleanliness and lubrication.
