12. TROUBLESHOOTING GUIDE
A. HYDRAULIC CYLINDER NOT WORKING - Check level of hydraulic fluid (see sight gauge on tank). Check
to see if pump is functioning properly by attempting to use another cylinder or pressure gauge. If pump is
working properly, check the pressure on the line. The relief valve may be by-passing fluid at too low
pressure. If cylinder is still not functioning properly, check the line for stoppage. The pistons in hydraulic
cylinders are virtually trouble-free, but occasionally one will have a scored wall and allow oil to flow around
the piston. In this case, replace the cylinder.
NOTE: Refer to repair parts section on valve bank settings on individual relief cartridges.
B. HYDRAULIC MOTOR NOT WORKING - Check lines for kinks or pinched place. If motor is “bogging down”
under load, recheck the relief valve setting on the cutter valve - 2500 PSI.
C. HYDRAULIC VALVE - Failures in the hydraulic system are almost always caused by other elements in the
system other than the valve; so the entire system should be checked before valve is changed. A
malfunction in any hydraulic valve section will require replacement of that section (but not the replacement
of the valve bank) since the insides are honed to fit individually. Attachment such as the relief valves and
detents may be serviced individually.
D. STRUCTURAL MEMBERS - Failure in structural members generally results from rough treatment. While
they are constructed to withstand abuse, they cannot be made strong enough to withstand abnormal
abuse. The factory does not warrant these parts to any extent other than in normal use in grass, weeds,
brush, small bushes, and small trees which the unit is designed to cut.
Arrange the chains so that when tightened, the
chains are pulling downward and against
themselves. Carefully tighten the securing chains or
other fasteners using boomers or binders to apply
maximum tension. Use extreme care when
attaching and removing the securing devices as the
extreme tension involved when released has the
potential to inflict serious injury.
While hauling the tractor and implement, make
occasional stops to check that the tractor and
implement have not moved or shifted and that the
securing chains have maintained tension. If during
transport a hard braking, sharp turning, or swerving
action was performed, stop at the next safe location
to inspect the security of the load. OPS-U- 0026
