Autoquip TITAN UPENDER - Manual (Page 31)

31
PROBLEM POSSIBLE CAUSE AND SOLUTION
Upender seems bouncy during
operation. • Lower the Upender to the Tilt Return position
and continue to hold “Tilt Return” button an
additional 10-30 seconds to bleed air from the
cylinder.
• Check for oil starvation.
Motor labors or heats
excessively. • The voltage may be low. Check at the motor
terminals while the pump is running loaded, not
at the line source or while the pump is idling.
Inadequate wiring can starve the motor even
when the source voltage is ample.
• Most of Autoquip’s standard motors are rated for
intermittent duty (two minute run times with two
minute rests). If a single-phase motor is being
run more than 15 – 20 motor starts per hour, or
a 3-phase motor more than 200 starts per hour,
the problem may be motor over-heating.
• Running against relief pressure unnecessarily
due to over loaded Upender or hitting physical
stops.
• Failure to observe wiring diagram on nameplate
for proper voltage connections.
• The pump may be binding from oil starvation,
which develops high internal heat. Check for
low oil level or closed breather holes in the
reservoir fill plug. The pump can be irreparably
damaged by oil starvation and may have to be
replaced.
