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
saw housing (item 49), making sure the inserts
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).

the blade support knob (item 52).
1. Insert the hex key through the hole in the outer
end of blade (item 56 or 58) and pull the blade
to the outer end of stroke.
