Safety

2.5Attention

!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.

2.6Further 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.

2.7Combination with Accessories

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.

2.8Exchange of Parts

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.
