MODEL 638.244 with ENGINE 104.900
Danger! | Risk of accident because of automatic startup when operating in jacked-up state. Risk of injury from rotating parts if running engine or drive shaft accessed whilst engine is running. | Check that jacks are securely positioned. Driver's seat should only be occupied by an authorized person. Wear buttoned-up, tight-fitting clothing. Do not touch hot or rotating parts. | |
Danger! | Risk of fatal injury through trapping or crushing by rotating parts during testing on the brake test stand | Only leave the vehicle in emergencies whilst the vehicle is on the rollers. No persons should be underneath the vehicle or in the vicinity of rotating parts during testing. In emergencies, switch off the test stand using the EMERGENCY OFF switch. | |
Danger! | Risk of poisoning if brake fluid is ingested. Risk of injury if eyes and skin come into contact with brake fluid | Only pour brake fluid into suitable and appropriately marked containers. Wear protective clothing and glasses when handling brake fluid. | |
Danger! | Risk of accident when starting up the vehicle because of lack of braking power when service brake operated for first time after repair work | Before starting up the vehicle, press brake pedal several times until pressure has been built up and maintained in the brake system. | |
