KEEP YOUR SAW CLEAN -
LUBRICATE REGULARLY
There's no way to prevent sawdust from col-
lecting on the saw mechanism. To keep the
saw operating smoothly and efficiently, take a
few minutes to re gularly remove the side panel
to clean out the sawdust - about once a month
clean and lubricate the saw mechanism.
It's easy to do. With a whisk broom or b111sh
clean sawdust from mechanism. Then lubri-
cate the parts indicated at right . DON'T
over-lubricate - it will only collect sawdust-
wipe off excess oil and grease. Don't get oil
or grease on the belts or pulleys.
Lubricate with ball bearing grease or
No. 130AA Lubriplate grease (avail-
able from hardware or sporting goods
store):
Lubricate with S.A.E . No. 10 oil:
NOTE: Motor beari11gs aud saw arbor beariugs
are permauetztly sealed agaimt dust and dirt - no
furtber /ubricatiou is necessary.
