WARNING!
• Do not stand, sit or climb onto the tilter.
• Do not load or unload a moving tilter.
• If the tilter fails to move or exhibits strange movements
or sounds, stop immediately. Do not operate the tilter
until it has been checked and repaired.
• Obey all warning labels.
• Load the lift only in the lowered position.
• Do not stand near the tilting side when tilting containers
of loose parts. Parts may fall out of the container and
could harm the operator.
6. All people and unrelated objects must stand clear of
the lift when operating in order to avoid personal injury or
property damage.

MAINTENANCE
Generally, the tilter lifts will require little maintenance. How-
ever, routine inspection and maintenance will minimize costly
repairs or hazardous conditions.
WARNING!
Before servicing the unit, read and understand
this entire section and the section entitled Op
-
erating Instructions. Never go under or service
a tilter with a load on the platform or with the
platform in a raised position. Always service the
tilter in a down or chocked position.
A. ROUTINE MAINTENANCE
All routine inspection and maintenance should be performed
monthly. When servicing the tilter in a partially or fully raised
position, chocks or safety pins must be in place to secure the
platform during maintenance. Follow the chocking procedure
in Section 5B if chocks or safety pins are not available. Con-
tact Presto-ECOA for the recommended parts.
1. Safety steps
a) The unit using a power supply of 115 Volt AC must
be disconnected from its power source.
Do not
work
on electrical parts unless you are a qualified electrician.
b) AC 3 phase or high voltage units must have the power
disconnected via standard lock out, tag out procedures
prior to servicing.
Do not
move the unit in an up or down
motion while performing maintenance.
c) For performing any maintenance the unit must be
fully secured according to Section 5B.
Do not
remove
hydraulic lines unless the tilter has been lowered to its
fully secured position. This should be verified several
times by pushing the down button on the switch.
d) When removing hydraulic hoses, crack the fittings
slowly to be sure that any hydraulic pressure that my
be residual is released.
2. Inspect the following:
a) Check the oil level and add oil if necessary according
to the instructions on the hydraulic chart and schematic.
b) Check the bolts on the pivot bar that holds the tilt
platform in place, if loose tighten.
c) Check hydraulic lines for damage or leaking. Replace
if damaged.
d) Check for oil spots or leaks around fitting and tighten.
e) Check wiring for damage. Replace immediately if
any signs of wear are evident.
f) Bearings on all lifts are permanently lubricated. (
Do
not
lubricate bearings.) Replace if worn.
B. TROUBLESHOOTING MAINTENANCE
All servicing should be done by qualified personnel who
should have read and understood all of the information pro-
vided in the Operating, Installation and Maintenance sections
in this manual.
1. Tilt will not move
.
a) For the 115 volt and 3 phase AC units:
• Check the power switch, fuses and overload as
-
sociated with its electrical circuits.
• Check voltage at motor; motor may have failed.
2. Operational noises
(tilter is very noisy)
a) Tilter may be overloaded or jammed. Check
load weights and obstructions.
b) For 115 volt AC motor, check voltage at terminal.
May have low voltage.
c) Oil shortage, reservoir low or oil line failure.
Repair or replace.
d) Down valve open, check wiring. Replace if
necessary.
3. Motor overheats
:
a) Excessive cycling (15 cycles per hour maximum).
Check actual time in use.
b) Low voltage-check voltage of 120 volt motors.
