Perkins D6500 Installation & Operational Manual page 30

Hand valve is leaking oil
This is typically caused by worn or damaged seals. Install new seals with part number D63217
In some cases, the spool itself is worn. If so, replace the hand valve.
Unable to achieve 1950 psi at the hand valve
The truck's pressure setting may be too low. Adjust the truck pressure according to the manufacturer's
instructions.
If pressure cannot be increased further, it may be necessary to install a speed up switch which will rev
the engine higher during peak need to deliver the desired pressure. Note that speed up switches will
increase fuel consumption.
Unable to achieve over 1400 psi
The truck pressure is too low. If adjustments do not help, the pump may be bad or underpowered.
Contact your truck manufacturer.
Lifter breaks upper bar of carts
The upper bar of the cart is typically broken when the cart is lifted while it is excessively loaded, or while
the lifter is operated too quickly. Adjust the speed of the lifter to bring the cycle time to 6-8 seconds.
Make sure the pressure is set no higher than 1650 psi.
Make sure the lifter is not damaged. Bent or broken lifter parts can contribute to cart damage.
Lifter drops carts
Make sure the upper hook is not damaged and make sure the lower stop is in place. Some customers
have been known to remove the lower stop, but this leads to dropping carts and latch damage.
Carts which are damaged or have missing lower bars will obviously not latch properly and should be
repaired or replaced.
Some carts do not meet ANSI standards. Measure the problem cart and see that the bar to bar spacing
is within 14 ½ - 15 ¼.
