!  When the vehicle is on the brake tester roller set with the driven axle, exit the roller set only 

when the roller drive is running. Exiting when the roller drive is not on can destroy the electric 
motors due to extreme acceleration of the rollers. 

!  The brake tester may not be operated without a functioning slip monitoring. Otherwise there 

is risk of tire damage. 

!  Never start a vehicle engine using the roller set drive. This can lead to equipment damage. 
!  No vehicle with a rigid 4-wheel drive may be tested on the brake tester with a standard roller 

set. This can lead to damage to both vehicle and test lane. Please ask your MAHA service 
representative for more information. 

!  4 wheel drive vehicles cannot be tested using the standard roller set. Erroneous tests will be 

the result.  
A special 4 wheel drive control is necessary. Please ask your MAHA service representative 
for more information.  

!  Avoid unnecessary strain on vehicle and test stand.  

Drive the vehicle slowly onto the test stand.  
Pay attention that the vehicle has sufficient ground clearance.  

The test stand may only be operated with accessories which MAHA has provided or approved. 
This applies especially for every accessory with electrical and/or mechanical connections to the 
MAHA test stand.  

Only genuine MAHA spare parts may be used to guarantee reliable functioning and thereby the 
safety of the MAHA test stand. Original MAHA spare parts are manufactured under the highest 
quality standards.
