Yale 11353395D manual Section Iv - Lubrication, Changing Gearcase Oil

dd)DO NOT use limit switches as routine operating stops unless recommended. They are emergency devices only.

ee)DO NOT use hoist to lift, support, or transport people.

ff)DO NOT lift loads over people.

gg)DO NOT leave a suspended load un- attended unless specific precautions have been taken.

hh)DO NOT allow sharp contact between two hoists or between hoist and obstructions.

ii)DO NOT allow the rope or hook to be used as a ground for welding.

jj)DO NOT allow the rope or hook to be touched by a live welding electrode.

kk)DO NOT remove or obscure the warnings on the hoist.

ll)DO NOT adjust or repair a hoist unless qualified to perform hoist maintenance.

mm)DO NOT attempt to lengthen the wire rope or repair damaged wire rope.

nn)Personnel not physically fit or properly qualified, shall not operate hoist.

oo)DO NOT operate hoists unless hook moves in the same direction as indicated on the push button. If opposite direction occurs, see pre-operation checks, Section II Paragraph 2-4.b.

pp)DO NOT operate hoist unless limit switch is operating properly.

qq)DO avoid operating hoist when hook is not centered under hoist. Avoid side pulls and swinging of load or load hook when traveling hoist.

rr)DO operate hoist within recommended duty cycle and do not “jog” unnecessarily.

ss)DO conduct regular visual inspections for signs of damage and wear.

tt)DO NOT operate hoist with hooks that have opened up. See Section V, Paragraph 5-2.f.

uu)DO provide supporting structure that has an appropriate design factor based on the load rating and dead weight of the hoist. If in

doubt of the supporting structure’s strength, consult a structural engineer.

WARNING

DO NOT operate hoist with the hoisting rope out of the drum grooves. Such operation may result in damage to the rope and/or the rope breaking. This may result in dropping the load that can cause damage to equipment and injury to operator or other personnel. Hoist rope will remain in the drum grooves during operation under normal operating con- ditions, however, slack or kinked rope, excessive side pulls, swinging or jerking of load, or similar abuse, may cause the rope to leave the grooves.

vv)DO NOT use hoist in location that will not allow operator movement to be free of the load.

ww)DO, when starting to lift, move the load a few inches at which time the hoist should be checked for proper load holding action. The operation shall be continued only after the operator is assured that the hoist is operating properly and that the load is supported in the center of the base/bowl/saddle of the hook.

xx)DO Observe recommended inspection and maintenance procedures.

yy)DO Use common sense and best judgment whenever operating a hoist.

SECTION IV – LUBRICATION

4-1.GENERAL.The lubrication services outlined in Paragraphs 4-3 thru 4-6 should be performed before initial operation of the hoist. The lubrication services outlined in Paragraphs 4-2 thru 4-6 should be performed at regular intervals at least every six (6) months, coinciding with spring and fall seasons is recommended. The reason for this is that on hoists installed outside or in unheated areas a “cold test” oil is required in such (below freezing) climates making seasonal changes necessary.

4-2. CHANGING GEARCASE OIL.

a)Add 5% solution of Mobilsol A (or equivalent) to the oil and run for a short time. This will clean components and hold particles in suspension for draining.
