** Working pressure on a Hydro is 400 PSI. What is the 600 PSI Max. (805)
correct Relief Valve Setting? 400 psi x 150% = 600 psi
** A contractor wants to raise the car speed from 100 FPM 15"
to 125 FPM. It currently has a 12" sheave. What size sheave (125 /100 = 1.25 1.25 x 12 = 15)
is required?
** There is slight arcing at the Brushes and Commutator. None. (430)
What actions must be taken? "Heavy arcing is due to light brush pressure. Mechanical wear indicates heavy
brush pressure.

acceptable) (90 seconds is code)
5 year test (Class 5) is car at rated load and speed. Buffer must return in 90
seconds. CWT at rated speed and buffer must return in 90 seconds.
