SAFETY PRECAUTIONS 

 

Read these operating instructions carefully and thoroughly before 

attempting to operate the equipment. 

 

This operating manual should be available at the testing site at all times. 

 

Always follow the procedures and actions defined in this manual, failure to 

do so may result in personal injury or other damage. The manufacturer 

cannot be held liable for personal injuries or vehicle damage that occur as 

a result of misuse of the equipment. 

 

All the national and international safety guidelines and legal regulations 

are to be followed when operating testing equipment. 

 

The operator is obliged to adhere to all the regulations applying to the 

workplace and to ensure his knowledge of such regulations is up to date. 

 

Do not allow other personnel near the test vehicle or rollers while a test is 

in progress. Check that the area is clear before the rollers are started or 

the vehicle moved EACH TIME this action is taken. 

 

Testing often takes place with the engine running, to provide a vacuum 

supply to the brake servo.  Ensure exhaust extraction or adequate 

ventilation is used to clear the poisonous exhaust gasses. 

 

Do not modify the equipment or change any internal settings – this could 

result in a very dangerous condition where the rollers could be started  

WITHOUT a vehicle in the rollers! 

 

 

TESTING STANDARD 

 

When performing statutory MOT tests it is vital to follow the brake 

test procedure detailed in the latest version of the relevant MOT 

Inspection Manual
