INSTALLATION INSTRUCTIONS
These instructions have been prepared to assure you of
satisfactory operation through proper use of your Jarvis
Wellsaw.
Read them carefully and keep them for future reference.
POWER SUPPLY
Your Jarvis Wellsaw operates on 50 or 60 Hz., single
phase alternating current. Its voltage rating is indicated
on the name plate (either 115 or 230 Volt). If an exten-
sion cord is to be used, be sure that the wire size is ade-
quate to maintain full line voltage to the tool.
GROUNDING
Your Jarvis Wellsaw should be grounded to prevent the
user from electric shock or electrocution.TheJarvis
Wellsaw is equipped with an approved three conductor
cord and three prong grounding--type plug to fit the prop-
er grounding--type receptacle. The green conductor in
the cord is the grounding wire. Never connect the green
wire to a live terminal. If your Jarvis Wellsaw is the 115
volt model, it has a plug that looks like figure ”A”. If
your Jarvis Wellsaw is the 230 volt model, it has a plug
that looks like figure ”B”.
figure A figure B
grounding blade grounding blade
Do not use any adapters with the Jarvis Wellsaw
EXTENSION CORDS
Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy
enough to carry the current your Jarvis Wellsaw will
draw. An undersized cord will cause a drop in line volt-
age resulting in loss of power and overheating. The table
below shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use the
next heavier gage. The smaller the gage number, the
heavier the cord.

OPERATION INSTRUCTIONS
Before starting regular operation of the Jarvis Wellsaw,
we recommend that you make a few cuts with a fine pitch
blade to acquaint yourself with the operation of the tool
before using any of the coarser blades.
A. AVERAGE CUTTING AND RIPPING:
1. Place your work piece on a solid support at a
convenient working height.
2. Adjust the material so that the line of cut will be
close to the support. Secure it firmly.
3. To prevent starting torque of the motor from
pulling the saw away from line of cut, the opera-
tor should make a few short strokes until the
blade has cut into the material about 1/4 inch be-
fore squeezing trigger switch.
4. Both hands should be on the saw at all times
while cutting. Continue holding the tool with
both hands until the saw blade comes to a
complete stop.
5. The saw should be kept at a 90 degree angle to
the work piece while cutting material that is
thicker than 1 inch.
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 the mate-
rial while cutting.
9. Never permit any part of the saw, except the
blade and 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.
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 a 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 SMALL RADII:
E. 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 36) and its gasket (item 35). 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 30) gently into the bores on
blade support clamp (item 22).
2. Align the blade support clamp (item 22) onto

stay in place.
3. Assemble (3) studs (item 29) with cap nuts (item
23) and place them through the saw housing and
the blade support clamp.
4. Draw down all (3) cap nuts (item 23) evenly un-
til the inserts are bottomed out into the saw hous-
ing.
5. Remove the cap nuts (item 23) and the blade
support clamp (item 22). (The inserts should
now be properly set into the saw housing).
6. Assemble blade support (item 55 or 57) over the
inserts on the saw housing. Place the blade sup-
port clamp (item 22) on the saw housing and fas-
ten it with the studs (item 29), the cap nuts (item
23) and the phillips screws (item 24).
7. Install handle stud (item 54) using two larger
phillips screws (item 53).
C. BLADE REMOVAL:
