Braun RA300 service manual Keep clear of area in which ramp operates

Page 12
If you are an attendant operating the ramp, it is your responsibility to oversee and/or assist in performing safe passenger loading and unloading procedures. Observe your passengers at all times when they are entering and exiting the vehicle. Attendants must
Gravity Down Drift
Deploy Gravity Down Drift (All RA300 models):
When deploying (unfolding) the ramp, the ramp pump motor stops running when the ramp reaches an approximate 45° angle (shut off point). The ramp continues to slowly lower the remaining dis- tance by the force of gravity (non-powered).
Allow the ramp to unfold (deploy) fully before boarding the ramp. Forcing the ramp out or down during the deploy (unfold) function, or boarding onto the ramp before it is fully-deployedmay re- sult in damage to the ramp and/or drive assembly.

The ramp opera- tor (attendant) and bystanders must keep clear of the area in which the
ramp operates and clear of all mov-
ing parts. Attendants must ensure that passengers keep clear of the area in which the ramp operates. Do not attempt to grip or hold the ramp, ramp drive arm assemblies or the tension cables.
Provide adequate clearance outside of vehicle to ac- commodate ramp. Failure to do so may result in serious bodily injury and/or property damage.
WARNING
Be certain there is adequate clearance outside the vehicle before deploying the power ramp.
RAMP OPERATION
Ramp Power Operation
The power ramp is attendant operated and activated by the control switch provided by the vehicle con- verter (ramp installer). A momentary contact ramp control switch (center off) will typically be provided near the driver. The control switch may be part of a panel providing other features and controls (power on/off indicators, LED’s, etc.).
Power Ramp Safety

Before operating the ramp, park the vehicle on DOHYHODUHDDZD\IURPYHKLFXODUWUDIÀF3ODFH the vehicle transmission in “Park” and engage the parking brake. Meet all other interlock conditions (as equipped). Activate the vehicle “kneel” system to lower the vehicle (if so equipped). Lowering the vehicle reduces the slope of the ramp.

be aware of any special needs and/or procedures required for safe transport of wheelchair passengers.

Do not attempt to load or unload a passenger in

DZKHHOFKDLURURWKHUDSSDUDWXVWKDWGRHVQRWÀW on the ramp. Do not exceed the 660 pound (300 kilograms) load capacity of the ramp. Passengers should enter and exit one at a time. The attendant should not board the ramp with the passenger except when assistance is required and the load capacity is not exceeded. Always return the ramp to the stowed position when not in use.

WARNING

Keep clear of area in which ramp operates.

Stow Gravity Down Drift ("Y" ramp models only):

When stowing the ramp and it reaches an approxi- mate 15° angle (shut off point), gravity lowers the UDPSWRWKHSDQ ÁRRU

CAUTION

Allow ramp to deploy fully before boarding. Failure to do so may result in damage.
