Autoquip TITAN UPENDER - Manual (Page 28)

DANGER !
To avoid personal injury, NEVER go under the Upender platform until the load is
removed and the platform is securely blocked in the open position.
Upender tilts very slowly. • Check for pinched tubing or hose. Where pipe
is used, check for obstruction in the line.
• The oil is extremely viscous due to low ambient
temperatures. Add or replace with lower weight
oil that stays thinner in cold conditions (5W-15,
etc.)
PROBLEM POSSIBLE CAUSE AND SOLUTION
Upender tilts, then drifts back
slowly after the pushbutton is
released. • The solenoid valve may not be seating.
Remove the solenoid coil and check again. If
the Upender does not hold, the valve cartridge
should be removed and cleaned or replaced as
necessary.
• The oil line, hose, or fitting may be leaking.
Check and repair if necessary.
• The “check valve” may not be seating. This is
indicated by the pump shaft and motor turning
backward on their own with no power applied.
Generally, this condition can be heard.
Replace the pump assembly.
