Safety glasses conforming to standard BS EN 166:1996 must be worn when working on
this equipment for the following reasons:
1. The test equipment is capable of producing high pressure fluid jets or sprays which
can cause severe eye injury in the event of a malfunction.
2. The test equipment uses fluid which is harmful to the eyes.
Gloves conforming to standard BS EN 407:1994 should be worn if regular contact with
test fluid is likely.
Gloves should also be worn when handling fixture parts or injectors after testing which
may be hot. Refer to the Health & Safety Data Sheets.
Safety footwear must be worn in the test area at all times. Injury to the feet may be
sustained in the event that equipment under test (during loading or unloading) or
covers, are dropped.
High Voltage!
Isolate the electrical supply by removing the mains lead before performing any
maintenance operations. Do not work on electrical equipment while voltage is supplied.
If such cannot be avoided, e.g. for measurements, tests or adjustments, have the action
carried out by qualified personnel only.
Do not open the guard while the system is running. Wait for the machine to stop before
opening the guard.
Do not attempt to remove the rear cover of the machine while the system is running.
Wait for the machine to stop, ensure the pressures have decayed to zero and the
machine is isolated from the services before opening.
It is mandatory to clean injectors in an ultrasonic tank/device before installing on the
YDT-35. Failure to do so may cause contamination of the fuel system on the YDT-35.
