Safety

 I

nformation

Only operate a Chunc 45

75

 with the 

Chunc option AAT v-max pushing 
and braking aid if training has been 
provided and if this manual, the 
Chunc user manual  and the v-max 
user manual been read in full. For 
more information also see chunc.com 
and aat-online.de.

Consider stability at all times. Exercise 
caution when manoeuvring and 
turning especially on slopes. Do not 
attempt slopes or terrain you would 
not normally attempt without a 
pushing or braking aid, for example, 
slopes with a gradient steeper than 
disabled access ramps. 

Be aware of your stopping distance 
when using at full speed.

Anti tipping levers (1) should be 
engaged during use.

Beware of potential fi nger trap around 
the drive and rear wheel gears (2). 
Note: Spoke guards (3) are fi tted as 
standard and should not be removed.

T

rans

p

ortation

When used in accordance with these 
guidelines a Chunc Wheelchair is 
fi tted with the Chunc option AAT 
v-max pushing and braking aid can 
be used as a forward facing seat in a 
suitably adapted motor vehicle. The 
occupant and wheelchair should 
be secured with a 4 point tie down 
system with integrated lap belt and 
vehicle mounted shoulder belt. 

Ensure the battery pack (4) is located 
securely with the long Velcro straps 
(5) through the battery handle (6) and 
around the gas strut mount(7).

Engage the drive pinions in the rear 
wheel locking the drive unit in place
