Release the brakes manually Section 6 – Additional Procedures
6.3 Release the brakes
manually
WARNING
Do not manually disengage the brakes if the
MEWP is on a slope. If you do not obey, there is a
risk of death or serious injury.
1. Make sure that the MEWP is on firm, level
ground. Use wheel chocks or blocks at the front
and rear side of the wheels to prevent MEWP
movement.
2. Turn the main power disconnect switch to the
off position.
CAUTION
Do not use the hydraulic power with the brake
disengaged.
3. Find the drive-bypass valve on the inboard side
of the drive pump. Loosen the valve stem
(item
1
- identified with yellow paint - Figure 15)
90 degrees clockwise to bypass the drive pump.

NOTE
If the MEWP does not have a pressure gauge,
refer to the service manual for the installation
procedure.
5. Continuously push and release the knob (item
2
- Figure 16) of the hand pump until firm
resistance is felt or until the pressure gauge
(optional equipment) shows 300 - 430 psi
(2068 - 2965 kPa). The brake is now released to
permit wheel rolling.
