Maintenance and Lubrication
Maintenance
DANGER: Never put lubricants on the blade
while it’s spinning.
WARNING: To avoid injury from unexpected
starting or electrical shock, unplug the power
cord before working on the saw.
WARNING: For your safety, this saw is double
insulated. To avoid electrical shock, fire or
injury, use only parts identical to those identi­
fied in the parts list reassemble exactly as orig­
inal assembly to avoid electrical hazards.
Replacing Carbon Brushes
The carbon brushes furnishGd will last approximately 50
hours of running time or 10,000 on/off cycles Replace
both carbon brushes when either has less than IM’’
length of carbon remaining. To inspect or replace first
unpiug the saw Then remove the motor cap on the end
of the motor by removing 2 screws. Remove the lead
wires from the tabs on the brushes, then pull out the
brushes. To reassemble reverse the procedure. Tighten
the screws snugly but do not overtighten
Lubrication
Ail the motor bearings in this too! are lubricated with a
sufficient amount of high grade lubricant for the life of
the unit under normal operating conditions, therefore,
no further lubrication is required, (See below.)
Infrequent Lubrication as Required:
1. Lubrication of arm pivot for free movement,
a Apply oil between washer and contact face of
Table/Pivot casting
b Apply oil to pivot shaft next to inside surface of
ears on arm casting,
NOTE: Disassembly should be done by an authorized
service technician. Removal of the upper guard and the
stopshaft is necessary before pivot can be disassem­
bled Pay close attention to the spring-end positions in
the castings, mark with chalk to avoid later confusion.
2 Lubrication of mechanism which pivots lower guard;
(see picture) Use light household oil (sewing
machine oil) or a pressurized light spray oil on metah
to-metal or metai-to-p!astic guard contact areas as
required for smooth, quiet operation Avoid excess
oil to which sawdust will cling. Lubricate the lov^er
guard spacer, roller, pivot plate and ¡Ink pivot.
3. Lubrication of miter index Indents; Use a small
amount of grease on the miter index indents that are
located below the table on the front of the unit
NOTE: To reinstall the same brushes, first make sure
the brushes go back in the way they came out, This will
avoid a break in period that reduces performance and
increases wear,
Lower Blade Guard
Do not use the saw without the lower guard. The lower
blade guard is attached to the saw for protection.
Should the lower guard become damaged, do not use
the saw until damaged guard has been replaced,
Develop a regular check to make sure the lower guard
is working properly Clean the lower guard of any dust
or build up with a damp cloth, ___________ _
CAUTION: Do not use solvents on the guard.
They could make the plastic “cloudy” and brittle..
WARNING: When cleaning lower guard unplug
the saw from the outlet to avoid unexpected
start-up.
Saw Dust
Periodically, sawdust will accumulate under the work
table and base This could cause difficulty in the move­
ment of the work table when setting up a miter cut.
Frequently blow out or vacuum up the sawdust.
WARNING: If blowing sawdust, wear proper
eye protection to keep debris from blowing into
eyes.
