BOX SCRAPER HYDRAULIC CONNECTION
READ AND UNDERSTAND ALL SAFETY STATEMENTS
Read all safety decals and safety statements in all manuals before beginning any Snow
Blower hydraulic connection. Know and obey all OSHA regulations, local laws, and other
professional guidelines for your operation. Know and follow good work practices when
assembling, maintaining, repairing, mounting, removing, or operating this equipment.
1. Remove all the protective plastic caps from the hose ends.
2. Make the connection to your prime mover using the appropriate method below for your prime mover:
• If your prime mover has male or female threads for connecting the hydraulic hoses to the auxiliary
hydraulic lines, make certain that the threads, as well as the inside of the fittings and hoses, are
clean, then secure the hoses to the fittings using the torque specified in your prime mover’s
operator’s manual.
• If your prime mover has quick-couplers for connecting the hydraulic hoses to the auxiliary hydraulic
lines, you may need to purchase the proper quick-coupler fittings that you must install on the free
ends of the two hoses. In most cases, the owner’s manual for your prime mover will describe the
exact type of fitting that is needed for your hydraulic coupling system, but in no case should any
fitting have an allowable operating pressure of less than 4,000 psi. Once all the quick-coupler
fittings are properly installed, then the hoses can be coupled to the prime mover’s hydraulic valve
body or auxiliary hydraulic lines as per the instructions found in your prime mover’s operator’s
manual.
3. Carefully raise the 3-point hitch to check hose clearances and to check for any interference. Operate
the hydraulic cylinder(s) on this product to make the same checks.
4. Cycle the hydraulic cylinder(s) on this product several times from fully retracted to fully extended
until all air has been completely removed from the cylinder(s).
WARNING!
Do not lock the auxiliary hydraulics of your prime mover in the "ON" position.
Failure to obey this warning could result in death or serious injury.
NOTICE:
When shipped, the hydraulic cylinder(s) on this product contained air or an air-fluid mixture.
There are orifices beneath the port(s) in the hydraulic cylinder barrel(s) that will restrict the
exit of that air. Failure to remove all the air from the hydraulic cylinder(s) can cause
uneven, jerky cylinder movement when the hydraulic controls are being operated and
unwanted cylinder movement when the controls are not being operated.
