WARNING: Do not attempt under any circumstances, to
service,repair,dismantle, or disassemble any mechanical
or electrical components withoutphysically disconnecting all
power soumes.
CLEANING
Clean off any preservative on bright (machined) parts with
appropriate solvent (mineral spirits). Avoid getting cleaning
fluid on any rubber parts as they tend to deteriorate
rubber.
• Use soap and soft water on rubber and plastic parts.
° After cleaning, lubricate unpainted surfaces with a light
application of medium consistency machine oil. This lubri-
cation should be repeated at least once every six months.
NOTE: Instead of oil, a good quality paste wax can be applied
to rip fence and table surface. Paste wax will enhance move-
ment of workpieces. In addition to providing lubrication, paste
wax will help prevent rusting.
= Keep your machine and your workshop clean. Do not allow
sawdust to accumulate on saw or inside cabinet.
Frequently vacuum or blow out any sawdust that may
accumulate within cabinet.
• Be certain motor and internal mechanisms are clean and
are frequently vacuumed or blown free of any dirt.
LUBRICATION
All bearings on the arbor are shielded ball bearings. These
bearings are permanently lubricated at the factory.
• As needed, clean the grease off the rack and worm gears
of height and tilt mechanism. Lubricate rack and gears
with a medium viscosity machine oil.
• Be sure to lubricate trunnion ways and all bushings.
• Occasionally oil all other bearing points, including bIade
guard assembly, miter gauge and rip fence.
SERVICE
