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 41) and its gasket (item 40). 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 31) gently into the bores on
blade support clamp (item 21).
2. Align the blade support clamp onto saw housing
(item 51), making sure the inserts stay in place.
3. Assemble (3) studs (item 30) with cap nuts (item
22) and place them through the saw housing and
the blade support clamp.
4. Draw down all (3) cap nuts evenly until the in-
serts are bottomed out into the saw housing.
5. Remove the cap nuts and the blade support
clamp. The inserts should now be properly set
into the saw housing.
6. Assemble blade support (item 56) over the in-
serts on the saw housing. Place the blade sup-
port clamp on the saw housing and fasten with
the studs, the cap nuts and phillips screws (item
23).
7. Install handle stud (item 55) using two larger
phillips screws (item 53).

ing) into the hole in the end of push rod (item

with the hole in the push rod for the set screw to
be fastened. (It may be necessary to turn the ar-
mature fan to adjust the push rod properly).
