DANGER
Hydraulic fluid under high pressure can penetrate skin. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Use a piece of cardboard or wood
rather than hands when searching for hydraulic leaks. If
hydraulic fluid is injected into the skin or eyes, it must be
treated by a doctor familiar with this type of injury within a
few hours or gangrene may result. DO NOT DELAY.
!
WARNING
Be sure to relieve all hydraulic pressure before disconnecting
any hydraulic lines between the Retractable Box Scraper and
the tractor hydraulic system.
Refer to Figure 1-4:
1. Connect hydraulic hoses to tractor remote outlets.
2. Cycle hydraulic system by extending and retracting
hydraulic cylinder several times. It may be necessary
to purge the system of trapped air if operation
remains sluggish. The system may be purged as
follows:
a. Lower Box Scraper until it is resting on the ground
and shut tractor engine off.
b. Remove lower cylinder pin (#1) and then loosen
fitting (#3) on to allow fluid to escape.
c. Slowly activate tractor control valve to purge any
trapped air from the system.
d. Once the system has been purged, retighten
fitting (#3) and reattach cylinder (#4) to lower
lugs (#5) with pin (#1). Secure with cotter pin (#2).
