3.19.2.8 Drive at low speed [PR8]
1- Chock both wheels as indicated below :
2- Connect the pressure gauge to the pressure
plug "M" on the FUNCTION MANIFOLD.
3- Position the speed selector to (
).
4- Push the joystick forward to actuate a
FORWARD DRIVE movement. Adjust the
pressure relief valve setting if necessary.
5- Disconnect the pressure gauge.
3.19.2.9 Slewing to the left [PR9]
1- Connect the pressure gauge to the pressure
plug "M" on the FUNCTION MANIFOLD.
2- SLEW fully the structure to the LEFT. Adjust
the pressure relief valve setting if necessary.
3- Disconnect the pressure gauge.
3.19.2.10 Slewing to the right [PR10]
1- Connect the pressure gauge to the pressure
plug "M" on the FUNCTION MANIFOLD.
2- SLEW fully the structure to the RIGHT. Adjust
the pressure relief valve setting if necessary.
3- Disconnect the pressure gauge.

CAUTION
3.19.2.7. Brake release maximum pressure
[PR7]
1- Chock both wheels as indicated below :
2- Disconnect and cap the brake supply hoses
(see §3.10).
3- Connect a pressure gauge to the pressure plug
"M" on the BRAKE MANIFOLD.
4- TIGHTEN FULLY the setting screw for the
pressure relief valve [PR7].
5- Position the DRIVE SPEED selector on (
).
6- Push the joystick forward to actuate a
FORWARD DRIVE movement. The maximum
pressure reading on the pressure gauge must
be between 15 and 21 bar corresponding to
the setting of the pressure reducing valve.
Record the exact value indicated by the
pressure gauge.
If the pressure is below 15 bar or higher than
21 bar, consult your JLG distributor.
7- LOOSEN the setting screw on the pressure
relief valve [PR7] until the pressure drops just
under the value recorded previously, then
TIGHTEN the setting screw by ¼ turn.
8- Remove the pump handle and push the lever of
the release control valve to the released position
.
9- Insert the handle in the hand pump and actuate
the handle vigorously. Note the pressure peak
on the pressure gauge. If the pressure peak
exceeds 35 bars, loosen the setting screw on
the pressure relief valve PR7 by 1/8 of a turn
and check the pressure peak again.
10- Disconnect the pressure gauge.
11- Reconnect the brake supply hoses.
Maximum brake supply pressure = 30 bar.
Maximum admissible pressure peak during
use of the hand pump to release the brakes
= 35 bar.
