Section 6 – Additional Procedures Push, Winch and Tow the MEWP
6.2 Push, Winch and Tow the
MEWP
WARNING
Tip-over hazard. Make sure the platform is fully
lowered before you push, winch, or tow, unless
movement is necessary to clear an obstacle.
Sudden movement can cause the MEWP to
become unstable.
In emergency situations where the MEWP
functions are not available, and an obstruction
prevents the platform lower function, carefully
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
Runaway hazard. After you release the brakes,
the MEWP rolls freely on slopes. Do not manually
disengage the brakes unless the MEWP is on a
level surface or the MEWP is fully restrained.
Keep the travel path clear at all times.
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.
