Maintenance - Milwaukee 6370-20 Operator's Manual

1. Beginning at a corner, line up the sight line with
your cutting line. Tilt the saw forward, firmly fixing
the front of the shoe on the workpiece. The blade
should be just above cutting line, but not touching it.
Raise the lower guard using the lower guard lever.
Fig.4
2. Pull the trigger and allow the motor to reach full
speed before beginning cut. Using the front of the
shoe as a hinge point, gradually lower the back
end of the saw into the workpiece. Release the
lower guard lever.
3. When the shoe rests flat against workpiece,
advance the saw to the far corner. Release the
trigger and allow the blade to come to a complete
stop before removing it from workpiece. Repeat
the above steps for each side of the opening.
Use a Sawzall reciprocating saw, jig saw or
®
small hand saw to finish the corners if they are
not completely cut through.
Troubleshooting
If the blade does not follow a straight line:
• Teeth are dull. This is caused by hitting a hard
object, dulling teeth on one side. The blade tends
to cut to the side with the sharpest teeth.
• Shoe is out of line or bent
• Blade is bent
If the blade binds, smokes or turns blue from friction:
• Blade is dull
• Blade is on backwards
• Blade is bent
• Blade is dirty
• Workpiece is not properly supported
• Incorrect blade is being used

Warning
always unplug your tool before performing
any maintenance. Never disassemble the tool
or try to do any rewiring on the tool's electrical
system. Contact a milWaukee service facility
for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the
general condition of your tool. Inspect guards,
switches, tool cord set and extension cord for
damage. Check for loose screws, misalignment,
binding of moving parts, improper mounting, bro-
ken parts and any other condition that may affect
its safe operation. If abnormal noise or vibration
occurs, turn the tool off immediately and have the
problem corrected before further use. Do not use a
damaged tool. Tag damaged tools "DO NOT USE"
until repaired (see "Repairs").
Under normal conditions, relubrication is not neces-
sary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest MILWAUKEE service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears, spin-
dles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electrical
operation
Warning
electric shock and damage to the tool, never
immerse your tool in liquid or allow a liquid
to flow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your
tool since certain cleaning agents and solvents
are harmful to plastics and other insulated parts.
Some of these include: gasoline, turpentine, lacquer
thinner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use flammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
