3.2 Brake release circuit pressure
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 t o 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.

3.3.4. Mast elevation (PR4)

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 Relief Valve
Pressure Settings, adjust the pressure setting
as necessary.
3- Remove the pressure gauge.
