Reaching For Objects; Driving On Falling, Rising Or Transverse Gradients; Crossing Obstacles - Meyra 2.322 OPTIMUS 2 Operating Manual

Reaching for objects

Avoid an extreme forward or backward in-
clination of the upper body when picking
up or placing heavy objects. – Danger of
electric wheelchair tipping over, especially
in the case of narrow seat widths and high
seat heights (seat cushion)!
Driving on falling, rising or trans-
verse gradients
For safety reasons, the maximum permitted
gradient is limited because the tip-over sta-
bility and the braking and steering behav-
iour are impaired by a reduced floor/road.
☞ Observe chapter Technical data on
page 51.
Never lean towards the downhill direction
when driving on rising, falling or transverse
gradients.
Avoid jerky changes of the driving condition
(especially with critically adjusted driving
parameters as for example high delay val-
ues).
Always drive with a low speed on rising/fall-
ing gradients.
Extreme inclinations or slopes are to be driv-
en on with adequate final speed.
Never switch to push mode on gradients.
The automatic brakes are inoperative in the
push mode.
Do not push the vehicle on gradients.
While driving in curves and when turning
on inclinations and slopes there is a danger
of tilting.
Avoid driving on inclinations or slopes with
insufficient surface condition. Even with
only on sided existence of ice, water, moss
or similar on the ground, there is a danger
that the electric wheelchair will loose trac-
tion and begin to slide out of control. If re-
46
quired immediately bring the joystick back
into the neutral position.
Never drive faster than walking speed.
The braking force transferred to the driving
surface is much less on a downward slope
than on a level driving surface and is fur-
ther reduced by poor road conditions (e.g.
rain, snow, grit, dirt). A dangerous slipping
of the wheels due to excessive braking and
an associated unwanted course deviation
must be avoided by way of a careful dosed
braking.
At the end of the downward slope, take care
that the foot plates do not make contact
with the ground and endanger you through
a sudden braking effect.
Transverse surfaces to the driving direction
(e.g. transversely sloped pavements) effect
a turning of your electric wheelchair in the
downhill direction. You or an accompany-
ing person must compensate for this drift
by a counter-steering.

Crossing obstacles

The obstacle crossing capability depends
on the driving surface gradients, the ad-
justment of the leg supports and other
factors.
Each crossing of obstacles involves a risk!
– tilting danger of the electric wheelchair.
The crossing of obstacles is a special dan-
ger situation in which a combination of the
safety advice in the sections headed uphill
driving, downhill driving and driving trans-
verse to a slope must be observed in addi-
tion to other safety advice.
Keep well clear of obstacles like ruts, rails
and gully covers or similar sources of dan-
ger.
Always drive slowly and at a right (90°) angle
towards small obstacles, e.g. curbs/edges.
