solely the resp nsibiliy of the p r on making the claim S ch a declaraton is not to b confused wih third p rty certficaton of

conformiy,which ma also b desira le

Appendix A Overload type test

Position the jack on a lev el sur ace Apply a load

equiv alent to1.25×SW L to the lfting head and

operate the jack throug hout its entire rang e of

mov ement

Appendix B Stabi ity type test

Position the jack on a plane incl ned at6° to the

horiz ntal and with the long itudinal a is of the jack

p ral el to the g rou d and at9 ° to the plane

( se Fig ure 2) Apply a loa equiv alent to the SW L

to the centre of the l fting head when at its

max imum heig ht Repeat the test with the jack

turned throug h18 °

Appendix C Prooftest

Test each jack as fol ows:

a) raise the lfting beam to its ful desig ned

heig ht, ensuring that suficient hy draulc fluid is

present in the reserv oir at al times to prev ent

ing res of air to the hy draul c pres urizing

sy stem;

b) measure and record the ma imum raised

heig ht;

c) lower the l fting beam to its position of

ma imum hy d raulc pres ure;

d) ad just the ov erloa dev ice so that it is

inoperativ e;

e) a ply a loa to the lfting hea eq uiv alent

to1.25× SW L;

f) al ow to stand for5min to permit ex ansion;

g ) make any neces ary a justments to ensure

that the loa is maintained at1.25× SW L;

h) observ e the jack for any sig ns of c e p

for5min;

i u loa the jack an ex mine for permanent

deformation or faiure of any p rt;

j) reset the ov erloa dev ice so that it operates

betwe n the SW L and1.1× SW L when the lfting

beam is horiz ntal
