Vehicle Systems Testing And Adjusting
Tilt and Sideshifter Relief Valve Check and
Adjustment
1. Turn the key switch on and activate the hydraulics
until the hydraulic oil is at the normal operating
temperature. Put the carriage in the full sideshift
position.
2. With the motor at fast rpm, hold the sideshift posi-
tion and watch the gauge. The gauge indication is
the pressure that opens the relief valve.
3. The correct pressure setting is shown in the chart.
4. If an adjustment to the relief valve setting is nec-
essary, loosen locknut (5).
Relief Valve Adjustment
(5) Locknut. (6) Stud
5. Turn stud (6) clockwise to increase or counter-
clockwise to decrease the pressure setting of the
relief valve.
6. Tighten the locknut and check the pressure stting
again for correct adjustment.
Flow Control Valve Adjustment
The tilt and first attachment speeds can be adjusted
at the control valves. They can be adjusted by turn-
ing the plug in the hydraulic control valve body. The
lift speed can not be adjusted.
Do the procedure that follows to change the flow
control assembly.
1. Remove the nut from the slotted tie-stud of main
hydraulic valve.
2. Remove the slotted tie-stud from the valve.
3. Use Hex Wrench (6mm or 1/4 inch), turn the flow
control adjuster clockwise to increase the flow or
counterclockwise to decrease the flow.
4. Assemble the tie stud in the valve. Torque the stud
to 40.5 L 2.5 NIm (360 L 24 lbIin)
5. Reinstall the nut.
Hydraulic oil, under pressure, can remain in the
hydraulic system after the motor and pump have been
stopped. Personal injury can be caused if this pressure
is not released before any work is done on the
hydraulic system. To prevent possible injury, lower the
carriage to the ground, turn the key switch off and
move the control levers to make sure all hydraulic pres-
sure is released before any fitting, plug, hose or com-
ponent is loosened, tightened, removed or adjusted.
Always move the lift truck to a clean and level location
away from the travel of other machines. Be sure that
other personnel are not near the machine when the
engine is running and tests or adjustments are made.
Standard Lift Cylinder Air Removal
After the standard lift cylinder has been disassem-
bled and then assembled again, it may be necessary
to remove the air (bleed) from the cylinder.
1. With no load, lift and lower the mast and carriage
through one complete cycle.
2. With the forks on the floor, check the oil level in
the hydraulic tank. Add oil (if necessary) to bring
the oil level to the full mark.
3. With no load, lift and lower the mast and carriage
again through four complete cycles.
