TEST UNIT PERFORMANCE by operating the unit with a test load equal
to the load rating.
• Listen for unusual noises, and look for signs of damage as you operate the
unit.
• Observe the rotating drum, look for signs of loose or misaligned bearings.
• Make sure the unit responds to the control device. It must rotate as shown
on the control labels, and it must turn off when you release the control.
• Make sure the load moves smoothly without hesitation or strain.
• Check the brake. Raise the load, then lower it and stop it a few feet off
the ground. If the load continues to coast or creep under normal operating
conditions, the brake needs adjustment. Refer to brake manufacturer’s
instructions.
g
DISCONNECT ELECTRIC POWER and inspect electrical equipment.
• Check electrical wires for worn insulation, cuts, corroded connections,
and other damage.
• Make sure the electrical control box is securely installed. Look inside
the control box for signs of moisture, corrosion, burn marks, cracks, and
other damage.
h
CONNECT ELECTRIC POWER.
• Check voltage of electrical supply with a UL approved voltmeter. If
voltage is low, have a licensed electrician inspect the circuit.
• Check power supply at the motor and make sure it agrees with the motor
rating. Do not operate the unit until proper power is supplied to the motor.
Completely correct all problems before continuing. Use the troubleshooting
chart to help determine the cause of certain problems. See Table 2.
