THE  FOLLOWING  SAFETY  PRECAUTIONS

1.  Wear  personal  protective  equipment  such  as,

but  not  limited  to,  protection  for  eyes,  ears,  feet,

ment. Do not wear loose clothing or jewelry that may
catch on equipment moving parts.

2.  Do  not  lift  heavy  parts  or  assemblies.  Use

crane,  jack,  tackle,  fork  trucks  or  other  mechanical
devices.

3.  Select  an  area  for  assembly  that  is  clean  and

free of any debris which might cause persons work-
ing on the assembly to trip.

4.  Arrange  parts  to  be  assembled  neatly  in  the

work area and have tools or other mechanical assist-
ing devices in easy reach.

5. Inspect all parts and assemblies thoroughly and

remove  any  sharp  edges,  grease,  oil  or  dirt  which-
might cause pieces to slip when handling.

6. Preview the assembly instructions in your oper-

ator’s manual before proceeding further.

7.  If  the  assembly  instructions  call  for  parts  or

assemblies  to  be  blocked  up,  use  only  blocking
material  that  is  in  good  condition  and  is  capable  of
handling  the  weight  of  the  assembly  to  be  blocked.
Also, insure that the blocking material is on a clean,
dry surface.

8.  Never  put  hands  or  any  other  part  of  body

under blocked up assemblies if at all possible.

9.  Always  wear  goggles  or  safety  glasses  when
