ƒ When tracing the hoses, you should be looking for kinks or splits in the
material. These are most likely to occur in places where the hoses run out
of the machine and are susceptible to being pinched.
ƒ Once you trace the hoses all the way back to the Index Pin, then make
sure that you have a firm connection at the barb that connects into the
pins.
ƒ
Check the barbs for any splits or cracks. This is especially likely to occur
where the barb nipple comes out of the fitting part of the barb.
Loud Racket When Drilling
If your machine is making a loud racket when drilling you will need to check a
few adjustments on the machine. If necessary, refer to the Machine Adjustments
section to adjust the depth of the head and adjust the tabletop. If you have
checked these and the machine still has a racket you will need to check the guard
frame.
ƒ The Guard Frame could be moving from left to right on the Drill Frame
at the rear of the machine.
ƒ The short hex bolts on the sides, and at the rear of the machine should be
checked.
