check
1- Chock both front wheels as indicated below :
2- Connect the pressure gauge to the pressure
test plug at port "M" on BRAKE MANIFOLD.
3- Position the DRIVE SPEED selector switch to
HIGH ( ).
4- Activate a DRIVE FORWARD function by
pushing the controller forward (away from the
operator). If the maximum reading on the
pressure gauge is not between 15 and 21 bar,
ref er to
BRAKE RELEASE MAXIMUM
PRESSURE in § 3.3.7. If the maximum reading
is over 21 bar, consult your local JLG distributor
for servicing.
5- Remove the pressure gauge.
3.3 Circuit relief valve adjustment
3.3.1. Main pressure (PR1)
1- Chock both rear wheels as indicated below :
2- Connect the pressure gauge to the pressure
test plug at port "M" on FUNCTION MANIFOLD.
3- Position the DRIVE SPEED SELECTOR switch
to HIGH ( ).
4- Activate a DRIVE REVERSE function by FULLY
pulling the controller to the rear (towards the
operator). Note the maximum reading on the
pressure gauge. If the reading is not within ± 5
bar of the relief pressure shown in the table
titled
Relief Valve Pressure Settings , adjust the
pressure setting as necessary.
5- Remove the pressure gauge.
3.3.2. Right swing (PR2)
1- Connect the pressure gauge to the pressure
test plug at port "M" on FUNCTION MANIFOLD.
2- SWING the superstructure fully to the RIGHT
(jib over the front). Note the maximum reading
of the pressure gauge. If the reading is not
within ± 5 bar of the relief pressure shown in
the table titled
Relief Valve Pressure Settings ,
adjust the pressure setting as necessary.
3- Remove the pressure gauge.
3.3.3. Left swing (PR3)
1- Connect the pressure gauge to the pressure test
plug at port "M" on FUNCTION MANIFOLD.
2- SWING the superstructure fully to the LEFT
(jib over the front). Note the maximum reading
of the pressure gauge. If the reading is not
within ± 5 bar of the relief pressure show in the
table titled
Relief Valve Pressure Settings ,
adjust the pressure setting as necessary.
3- Remove the pressure gauge.

1- Connect the pressure gauge to the pressure test
plug at port «M» on FUNCTION MANIFOLD.
2- Perform a MAST RAISING function until the
the mast cylinder reaches the end of its course.
Note the maximum reading of the pressure
gauge. If the reading is not within ± 5 bar of the
relief pressure shown in the table titled
Relief
Valve Pressure Settings , adjust the pressure
setting as necessary.
3- Remove the pressure gauge.
3.3.5. Jib elevation (PR5)
1- Connect the pressure gauge to the pressure test
plug at port «M» on FUNCTION MANIFOLD.
2- Perform a JIB RAISING function until the jib
cylinder reaches the end of its course. Note
the maximum reading of the pressure gauge. If
the reading is not within ± 5 bar of the relief
pressure shown in the table titled
