RE 92750-01-B/06.2018, A10VG, Series 10,
Bosch Rexroth AG
To activate the bypass function:
1.
Switch off the combustion engine.
2.
Remove the plastic tamper-proof cap from the high-pressure relief valve with a
suitable tool (e.g., pliers).
3.
Loosen the lock nut (2) by turning it counterclockwise one half-turn with a
hexagon head screw (AF 10 for size 18 and AF 13 for size 28 to 63).
4.
Use a hexagon socket wrench (AF 3 for size 18 and AF 4 for size 28 to 63) to
turn the screw (1) clockwise until the screw (1) is against the spring seat. This
is indicated by the increased resistance. Then turn the screw (1) one half-turn
clockwise.
5.
Retighten the lock nut (2), turning clockwise to a torque of 10 Nm for size 18 and
22 Nm for size 28 to 63.
Removing the plastic tamper-proof cap will destroy it.
The maximum towing speed depends on the gear ratio in the vehicle and must be
calculated by the vehicle manufacturer. Do not exceed a corresponding flow of
q
V
= 30 l/min.
Only tow the vehicle out of the immediate danger zone.
CAUTIOn! Excessive heat generation and inadequate lubrication!
Risk of burning or property damage. High towing speeds and long towing distances
lead to excessive heat generation and inadequate lubrication. This will overheat and
damage the axial piston unit.
▶
Wear heat-resistant protective clothing, e.g. gloves.
▶
Only tow the vehicle out of the immediate danger zone.
nOTICE! Draining of the hydraulic circuit!
Risk of damage! While towing with the bypass function activated, the closed
hydraulic circuit drains itself. This can result in unintended functions when restarting
the travel drive.
▶
Start the travel drive only after completely filling and air bleeding the hydraulic
circuit (see chapter 8.1 “Initial commissioning” on page 47).
To deactivate the bypass function:
1.
Immediately following towing, switch off the bypass function.
2.
Restore the function of the high-pressure relief valve. To do this, perform the
steps under the “Activating the bypass function” in the reverse order: Loosen the
lock nut (2) with a hexagon head screw (AF 10 for size 18 and AF 13 for size 28 to
63), then turn the screw (1) counterclockwise with a hexagon socket wrench
(AF 3 for size 18 and AF 4 for size 28 to 63) as far as it will go.
3.
Retighten the lock nut (2), turning clockwise to a torque of 10 Nm for size 18 and
22 Nm for size 28 to 63.
4.
Place a tamper-proof cap on the screw (
1) to protect the pressure relief valve
against unauthorized adjustment.
