SYMPTOM

HRT (A6)
Dead length collets
sticking, and/or insuffi-
cient clamping force.

Air leaking around rear
brake disc.

Display reads:
Indr dn

Platter does not lift
(HRT 320FB)

REMEDY

n

Lubricate spindle and collet with a
Molybdenum disulfide grease.

n

Contact HAAS Service Dept. (Do Not use
air gun around rear brake disc). See
section 8.5.

n

Check Air Pressure (60psi min.)

o

Check for platter clearance or excessive

weight of workpiece.

n

Air pressure should be between 40

and 120PSI

PROBABLE CAUSES

n

Excessive spindle/collet friction.

n

Chips blown in between O-ring and brake
disc.

n

Insufficient Air Pressure.

o

Platter face prevented from lifting

n

Low air plressure
