Periodically, sawdust will accumulate 

under the work table and base. This 

could cause difficulty in the movement 

of the worktable when setting up 

a miter cut. Frequently blow out or 

vacuum up the sawdust.

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 further lubrication is 

required.
Lubricate the Following as necessary:
Chop pivot: Apply light machine oil to 

points indicated in illustration. 
Central pivot of plastic guard: Use 

light household oil (sewing machine 

oil ) on metal-to-metal or metal-to-

plastic guard contact areas as required 

for smooth, quiet operation. Avoid 

excessive oil, to which sawdust will 

cling.
Link: (which actuates the lower guard 

movement) may be oiled at the rear 

pivot, greased at ball bearing contact, 

and oiled where the link actuates the 

acetyl roller of the lower guard, if the 

down chop motion is hard to start.
