HIGH-PRESSURE HOSE
•
The AUTOBOX® (ABX-2L-V2) Hose Tractor is designed to be used with Parker Pro-Lance® and/or Spir Star Blast-Pro® hose ends. Standard
hose ends may not fit into Hose Tractor and/or Guide Tubes.
Note: MAXIMUM hose end diameter must NOT exceed .71 in. (18 mm)
•
Only high quality hoses intended for waterblast applications should be used as high-pressure hoses. Pressure rating of high-pressure hoses
MUST NEVER be exceeded.
•
Verify that the high-pressure hose is properly installed in the back-out preventer. Operate the high-pressure hose and waterjet tool at full
pressure to test the clamp force. Proper clamp force will provide good control of the hose in forward and reverse directions, and keep the hose
running through the Drive Rollers.
•
The AUTOBOX® (ABX-2L-V2) Hose Tractor MUST be supervised at all times.
•
HOSE LENGTHS
The ABX-2L-V2 has a variety of accessories that will require additional hose length to be considered in addition to the tube
bundle length. This should be verified prior to ordering high pressure hose for each job. The chart below shows the actual length of each con-
figuration and recommended additional length necessary to keep the assembly from lifting off the ground during operation. Provide the tube
bundle length and use the chart to follow the calculation below to determine the total hose length.
(Tube Bundle Length, in./mm) + (Actual Length of Configuration, in./mm) + (Recommended Additional Connection Length, in./mm)
= Total Hose Length in./mm
NOTICE
Do not use a shrouded hose or hose with a steel protective cover. This will cause severe damage to the Drive Rollers.
•
Open the door to install the high-pressure hose. The
HOSE CLAMP PRESSURE REGULATOR
on the Control Box MUST be turned
to zero pressure to open the Drive Rollers for easy hose installation. Insert the hose, equipped with the waterjet tool, between the Drive
Rollers. Increase the pressure on the
HOSE CLAMP PRESSURE REGULATOR
to extend the clamp rollers and clamp the hose. Close
and lock the door before operating the AUTOBOX
®
(ABX-2L-V2) Hose Tractor.
Test the Control Box before operating the AUTOBOX® (ABX-2L-V2) Hose Tractor with high-pressure water to verify the control valves move the
hose in the intended direction, and that the dump valve is working properly.
HOSE CLAMP
•
The Drive Rollers are controlled by turning the
HOSE CLAMP PRESSURE REGULATOR
. Use the
HOSE CLAMP PRESSURE GAUGE
to record desired pressure for future use. Clamp force will not damage hoses. Proper clamp force will provide good control of the hose in
forward and reverse directions, and will keep the hose running through the Drive Rollers.
WARNING
Do not fully release the hose clamp (decreasing pressure to zero) during operation, or the AUTOBOX
®
(ABX-2L-V2) Hose Tractor will release the
hose and may create a dangerous runaway hose condition, which can result in severe injury and/or death.
Crush Hazard. Keep hands, hair, and clothing clear of drive rollers and belts. Contact with moving parts can result in severe injury.
