Safety, Care and Handling
Proper repair is important to the personal safety of the maintenance technician and to the safe and reliable operation of
the 621B Scraper. This manual outlines basic recommended procedures, some of which require special tools, devices or
work methods. Although not necessarily complete, a list of warnings is provided at the front of this manual.
Improper repair procedures can be dangerous and may cause INJURY.
READ AND UNDERSTAND ALL SAFETY WARNINGS BEFORE PERFORMING REPAIRS ON THIS
Basic safety cautions are listed before the procedures to which they apply. Warning labels have also been put on the
machine to provide instructions and identify specific hazards, which if not heeded, may cause INJURY or death. These
labels identify hazards during repair, but there is no way to label the machine against all such hazards. Warnings in the
service manual and on the machine are identified by the word WARNING.
Operations that may result in machine damage are identified by labels on the machine and are noted in this manual by
the word CAUTION. Every possible hazard cannot be anticipated. If you use a procedure, tool, device or work method
not specifically recommended, ensure that it is safe for you and others. Make sure that the machine will not be damaged
or made unsafe by the procedure you choose.
Do not lift heavy components by hand. Use a lifting device and follow the recommendations in the manufac-
turer's manual. Provide adequate support and use assistance during procedure. Use lifting tools as shown in
illustrations to get the correct balance of the component you lift. This makes your work safer at all times.
Lower it onto blocks or stands. Make sure the component rests solidly. A sudden fall can cause an accident.
When jacking up the machine, be sure to block the wheels at front and rear. Always place earthmoving equipment (bowl
and apron) in lowered position when parking machine to prevent possible injury to personnel and to prevent needless
stress on hydraulic and mechanical components.
