LIMB SAW HYDRAULIC CONNECTION
SAFETY FIRST!! READ AND UNDERSTAND THE SAFETY INSTRUCTIONS
(pages 3-5
of
this manual)
BEFORE BEGINNING ANY HYDRAULIC CONNECTION.
1.
You must purchase and install two hydraulic hoses that have fittings permanently attached to each end. These hoses
and fittings must meet the following specifications:
Inside diameter ................................................. 0.375"
(3/8")
Maximum operating pressure ............................ 3,000psi.
Hose end fittings ............................................... One hose end must be a female
NPT fitting. The fitting for the other
end can be whatever you determine to be the most beneficial to making the connection to your power unit.
Length ............................................................... You must make this determination based upon recommendations
provided in your power unit's operator's manual. The hoses must be long enough to avoid applying any tension to
them
(i.e. stretching)
in all operating positions of this product. Excessive length could cause the hoses to drag on
ground, be pinched in equipment, become entangled in moving parts, etc., any of which will shorten life of hoses
and could cause injury to operator or others near equipment.
2.
Remove all protective plastic caps from hose ends and this product's connection fittings.
3.
Ensure the male and female threads, as well as the inside of the hoses, are clean.
4.
Make connection to power unit using appropriate method below for your power unit.
If your power unit has male or female threads for connecting hydraulic hoses to auxiliary lines, ensure all threads
and inside of fittings and hoses are clean; then secure hoses to fittings using torque specified in your power unit's
operator's manual.
If your power unit has quick-couplers for connecting hydraulic hoses to auxiliary hydraulic lines, you may need to
purchase proper quick-coupler fittings which you must install on the free ends of the two hoses. In most cases, the
owner's manual for your power unit will describe the exact type of fitting which 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
quick-coupler fittings are properly installed, the hoses can then be coupled to the power unit's hydraulic valve body
or auxiliary hydraulic lines as per the instructions found in your power unit's operator's manual.
5. Carefully raise the loader arm and cycle the tilt cylinders to check hose clearances and to check any interference.
WARNING
Do not lock the auxiliary hydraulics of your tractor or power unit in the "ON" position.
Failure to obey this warning could result in death or serious injury.
