3.1 General Procedures
IMPORTANT: Troubleshooting the SIDESHIFT or CLAMP
circuits can be found in J-Series Carton Clamp Service
Manual, part no. 6883648.
3.1-1 Truck System Requirements
• Truck hydraulic pressure should be within the range
shown in Specifications, Section 5.1. PRESSURE TO
THE ATTACHMENT MUST NOT EXCEED:
Low Pressure – 2755 Psi (189 bar)
High Pressure – 3625 Psi (250 bar)
• Hydraulic flow should be within the volume range as
shown in Specifications, Section 5.1.
• Hydraulic fluid supplied to the attachment must meet the
requirements as shown in Specifications, Section 5.1.
3.1-2 Tools Required
In addition to a normal selection of hand tools, the following
will be required:
• Inline Flow Meter Kit:
20 GPM (75 L/min.) - Cascade Part No. 671477.
• Pressure Gauge Kit:
5000 psi (345 bar) - Cascade Part No. 671212. Two kits
are required.
OR
Wireless Pressure Monitor Kit:
Pressure transducers monitor the hydraulic pressure
and wirelessly transmit the data to the receiver display.
• Assorted fittings and hoses to adapt the gauge and flow
meter to the components being tested.
WARNING: Before servicing any
hydraulic component, relieve pressure
in the system. Turn the truck off and
move the truck auxiliary control valves
several times in both directions.
After completing any service procedure, test the
attachment through several cycles. First test
the attachment empty to bleed any air trapped
in the system to the truck tank. Then test the
attachment with a load to be sure it operates
correctly before returning to the job.
Stay clear of the load while testing. Do not raise
the load more than 4 in. (10 cm) off the floor while
testing.
