Replacing Carbon Brushes; Lower Blade Guard; Sawdust; Lubrication - RIDGID MS1050 Owner's Manual

Replacing Carbon Brushes

The carbon brushes furnished will last approximately 50
hours of running time or 10,000 on/off cycles. Replace
both carbon brushes when either brush has less than 1/4"
length of carbon remaining. To inspect or replace first
unplug 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.
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 regu-
lar check to make sure the lower guard is working prop-
erly. 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.

Sawdust

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. Fre-
quently blow out or vacuum up the sawdust.
WARNING: If blowing sawdust, wear proper eye
protection to keep debris from blowing into eyes.

Lubrication

All the motor bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of the
unit under normal operating conditions. Therefore, no fur-
ther lubrication is required.
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

stopshaft is necessary before pivot can be disassembled.
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 illustration): Use light household oil (sewing
machine oil) or a pressurized light spray oil on metal-
to-metal or metal-to-plastic guard contact areas as
required for smooth, quiet operation. Avoid excess oil,
to which sawdust will cling. Lubricate the lower guard
spacer, roller, pivot plate and link 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.
