D.  TESTING THE TILTER WITH NO  LOAD

Before operating the tilter, read and understand this section.

1.  Before testing the tilter, clear the area of any loose mate-

rial.  Be sure the tilter has no obstruction above it or on 

any side.  Using the controls provided, briefly operate 

the tilter (5-10 seconds).  If the tilter begins to rise with 

a humming sound and functions properly, continue to 

the full upright position.

CAUTION!

If the tilter does not rise immediately, or there is 

any operational problem, stop it immediately.  Be-

fore continuing, check the rotation of the pump 

and motor and the voltage at motor terminals, 

again briefly operate the tilter.  If the tilter does 

not  move  smoothly  with  the  humming  sound, 

stop and review the procedures in the section 

on troubleshooting (Section 5B).

2.   After raising the tilter completely, lower the tilter com-

pletely.  It should move slowly and smoothly without a 

humming sound.  If the tilter operates properly, raise 

and lower the tilter and stop at different levels in order 

to familiarize yourself with the tilter’s operations and 

movements.

WARNING!

As  the  tilter  platform  and  forks  move  up  and 

down, pinch points are created at locations near 

the base of the frame.  While operating the tilter 

the operator should be standing clear of the tilter 

and container while in use.  In that way, the op-

erator’s arms, legs or clothing will not be caught 

in the moving parts.  During operations the op

-

erator should avoid the pinch point areas which 

are located on either side of the tilter.  See the 

diagram pointing out the particular pinch points.

OPERATION

A

.  METHOD OF OPERATION

All tilters are provided with a special hydraulic relief valve, 

which is factory preset to the maximum safe capacity of the 

container tilter (see the nameplate attached to the tilter.)  

Activating and holding the up switch will energize the motor.  

The motor is attached to a positive  displacement pump which 

draws hydraulic fluid from the reservoir and transfers it under 

pressure to the cylinder.  This forces the piston forward and 

the raise to rise in a thirty (30º) to ninety degree (90º) arc.  

Releasing the up button will stop the tilter.  A check valve 

between the pump and piston holds the platform in position.  

Depressing and holding the down button of the switch will 

energize a solenoid, which allows the oil from the cylinder 

to return to the reservoir through a preset flow control.  This 

allows the tilter to lower smoothly and at a controlled speed.

                             

CAUTION!

Do not

 maintain the up button on the switch en

-

ergized if the tilter does not move or has reached 

its upper limit.  This may cause damage to the 

motor, pump and controls.

B.  OPERATION PROCEDURES

In order to operate the tilter, follow these operating proce-

dures:
1.  Read and understand all the instructions before op-

erating.  If the tilter has modifications or accessories, 

read and understand their functions.

2.  Load the tilter correctly.  Refer to the attached name-

plate for load capacity information.
a)  Load the tilter while it is in the lowered position.

b)  Do not

 exceed the maximum rated load (note 

that load capacity is on the nameplate of the 

tilter).

c)  Place the load in the center and at the very back 

of the platform (pivot end).

d)  If the load is unstable or may become unstable, 

fasten it into position.

e)  Use additional precautions when tilting a load 

of loose parts.  Excessive (what?) can cause 

parts to fall out of the container.

3.  Operate the tilter.

a)  To raise the tilter, press and hold the up button 

on the switch.

b)  To lower the tilter, press the down button on the 

switch.

c)  Release the button to stop the tilter in either 

direction.

4.  Wait until the tilter has come to a complete stop 

before loading or unloading.

5.  Stand clear of the tilter when operating in order to 

avoid injury.
