Wait for the hydraulic fluid to cool before serv-
icing any hydraulic component. Hot hydraulic
fluid can cause severe burns.
Warning
Before starting the engine be sure all hydraulic
connections are tight and all tools are removed
from the forklift.

3. Remove the transmission cover from the
frame.
4. Install a tee and pressure gauge capable of
measuring 0-4000 psi
(275,6 bar) at the 15
gpm section outlet of the tandem pump, Fig.
9.13.
Warning
Relieve hydraulic pressure before servicing any
hydraulic component. Escaping hydraulic fluid
under pressure can penetrate the skin causing
serious injury.

5. Start the engine. Operate the frame tilt control
several times to purge the system of air.
6. With the engine at idle, place the fork and
frame control lever in the “left” position and
hold until the frame tilt cylinder bottoms out.
Continue holding the lever in the “left” position
until the pressure readings are taken.
7. Check the pressure gauge reading. It should
read 1300 ± 50 psi (89,6 ± 3,4 bar). If not,
adjust the frame tilt “left” relief valve, Fig. 9.13,
turning the adjustment screw clockwise to
increase pressure or counterclockwise to
decrease pressure. Torque nuts on relief
valve to 10 ± 1.5 lb-ft (13 ± 2 Nm) after
adjustment.
8. Stop the engine. Operate the hydraulic
controls after the engine has stopped to
relieve any trapped pressure.
9. Remove the pressure gauge and tee from the
tandem pump and reconnect the hydraulic
line.
10. Start the engine. Operate the frame tilt control
fully several times to purge the system of air.
11. Install the transmission cover after adjustment.
