Head Lubrication
The head should be oiled every 30 to 40 hours of usage. The head, once it is broken in beyond its
initial start-up, should run very quietly with no loud metallic racket or grinding.
In order to maintain the machine in good working order, the head should never be run dry. The head
uses oil impregnated bushings that need to stay oiled for optimal performance.
The oil that is used in lubricating this machine consists of two ingredients: Non-Detergent, 30 WT
Motor Oil and Slick 50. The two are mixed at a ratio of 4:1 respectively.
SOLUTION STEPS:
1. Loosen the two plastic, tri-armed knobs that hold down the bit cover on top of the machine.
Remove the bit cover by lifting and sliding it to your right as you lift.
2. Locate the 4 lubrication holes in the top of the head. These may be partly covered by the spindle
housings, requiring a slight repositioning of the housings
