6. The saw should be pushed firmly into the mate-
rial while cutting.
7. Do not allow the saw blade or the blade support
to leave the work piece while cutting.
8. Never allow the saw blade to float into material
while cutting.
9. Never permit any part of the saw, except the
blade or the blade support, to contact the work
piece during the cut.
B. LARGE CROSS SECTIONS:
1. Rocking the saw in the cut will speed up the cut-
ting action. An 8 tpi (tooth per inch) blade is
recommended.
C. SINKING THE BLADE THROUGH A SUR-
FACE:
1. Your power hand saw is not designed for regular
use in starting its own hole by sinking blades
through a surface, commonly called “plunge
cutting”. If attempted, the operator must:
a. Keep the saw blade as parallel to the work
as possible.
b. Immediately, as the blade makes contact
with the work piece, start to draw the saw
back slowly from the starting point.
c. Repeat the operation outlined in “b”, if nec-
essary.
d. Have room to draw the saw at least 4--6 in-
ches before cutting through a 1 inch thick-
ness.
e. Do not force the saw blade, but keep it
moving slowly on the draw back from the
starting point. After the break through cut
has been made and the end of the blade sup-
port extends through the material at least
1--1/2 inches, the saw may be tipped to a
normal cutting angle.
D. NOT FOR CUTTING METAL:
1. Due to the blade speed and design, your
Jarvis
Wellsaw is not for cutting metal.
E. NOT FOR CUTTING SMALL RADII:
F. HEAVY & CONTINUOUS WOOD CUTTING:
1. For heavy or continuous wood cutting, lubricate
the blade grove with oil or
Jarvis
Wellsaw lubri-
cant 1062023.
2. When cutting wet or gummy wood or other ma-
terial where there is a tendency for a deposit to
build up on the sides of the blades, use a 50--50
mixture of kerosene and lubricating oil and
place it on the sides of the blade and the blade
support.
G. ALWAYS KEEP A SHARP BLADE ON THE
SAW:
1. Cutting with a dull or badly worn blade can
overload the saw and cause damage from over-
heating.
2. New blades can be purchased from
Jarvis.
MAINTENANCE INSTRUCTIONS
Always disconnect the saw from its power supply
before performing any maintenance.
Item numbers: refer to the parts diagram on page 4.
A. LUBRICATION:
1. The gear case should be kept 1/3 full of grease.
To check the grease level, remove the bottom
plate (item 43) and its gasket (item 42). It should
be checked every thirty days for saws that are
used moderately and every two weeks for saws
that are used daily. If replacement grease is re-
quired it should be obtained from
Jarvis
.
B. BLADE SUPPORT INSTALLATION:
1. Tap (3) inserts (item 32) gently into the bores on
blade support cover (item 22).
2. Align the blade support cover (item 22) onto saw
housing (item 54), making sure the inserts stay
in place.
3. Assemble (3) studs (item 31) with cap nuts (item
23) and place them through the saw housing and
the blade support cover.
4. Draw down all (3) cap nuts evenly until the in-
serts are bottomed out into the saw housing.
