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 of the wheels to prevent MEWP
movement.
2. Turn the main power disconnect switch to the
off position.
3. Push the plunger

of the brake auto-reset
valve on the drive manifold at the rear side of the

of
the hand pump until firm resistance is felt or until
the pressure gauge (optional equipment) shows
300 - 350 psi (21 - 24 bar). The brake is now
released to permit wheel rolling.
5. Turn the freewheeling valve knob
3
counterclockwise to a fully open position.
6.3 Winch and tow the MEWP
WARNING
Tip-over hazard. Make sure that platform is fully
lowered before you push, winch or tow. Sudden
movement can cause the MEWP to become
unstable. If you do not obey, there is a risk of
death or serious injury.
WARNING
Tip-over hazard. In emergency situations, where
the MEWP functions are unavailable, and an
obstruction prevents the platform lower function,
carefully move the MEWP. Move the MEWP
sufficiently far away to clear the obstruction. Do
not move at a speed faster than 50 mm/sec (2 in/
sec). If you do not obey, there is a risk of death,
serious injury, and/or MEWP damage.
WARNING
When you push, winch or tow, do not move the
MEWP at a speed faster than 3.2 km/h (2.0 mph). If
you do not obey, there is a risk of death or serious
injury.
WARNING
Do not push, winch, or tow the MEWP onto a
slope. Only brake the tow vehicle slowly. Do not
pull the MEWP down a slope to a winch. Make sure
that there are no personnel in the path you plan to
travel. If you do not obey, there is a risk of death,
serious injury, and/or MEWP damage.
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.
WARNING
Tip-over hazard. Disengage the brakes manually
before you push, winch, or tow the MEWP. If you
